It can address property and debt.
Terms may cover ownership, management, disposition, businesses, real estate, liabilities, estate coordination, and other lawful financial rights.
Temecula prenuptial agreement lawyers
Your wedding date is fixed. Your financial future should not be improvised.
A California prenup can define property, debt, business, inheritance, and support expectations before marriage. The agreement is only as useful as the process behind it: timing, disclosure, separate review, and precise drafting all matter.
Free initial consultation. No obligation to hire. Calling early does not commit either person to specific terms.
Seven calendar days is a statutory floor, not a strategy
Property, debt, business, and support terms require careful drafting
Child support rights cannot be adversely affected
The expensive mistake is usually the process
A signature does not make a rushed template immune from a later enforcement fight.
California courts examine voluntariness, timing, counsel or a valid waiver, financial disclosure, capacity, and other relevant circumstances. Starting days before the ceremony can turn a planning tool into evidence about pressure, incomplete review, or misunderstood rights.
Start with what needs protection or review
Which side of the agreement are you standing on?
Choose the closest fit. The immediate work changes when you are protecting an existing financial structure, reviewing someone else’s draft, or running out of time.
Protect the financial structure, not just the asset list.
A useful agreement considers ownership, management, appreciation, income, debt, contributions, valuation, and what happens on separation or death.
- A business, professional practice, or investment entity already exists
- Real estate, retirement, equity, or family wealth is involved
- Children from an earlier relationship or estate plans need coordination
- One person expects a gift, inheritance, sale, or liquidity event
Do not let the other person’s draft become your explanation of the deal.
Independent review should identify what changes from California’s default rules, what is missing, and which terms may operate differently at divorce or death.
- You received a draft from your fiancé or their attorney
- A support waiver, business clause, or estate waiver is included
- Schedules of property, debt, or income appear incomplete
- You feel pressure to sign before deposits, travel, or guests are affected
The seven-day rule is not seven days to invent the entire agreement.
For agreements signed on or after January 1, 2020, at least seven calendar days must pass between first presentation of the final agreement and signing. Disclosure, drafting, negotiation, and review come before that final interval.
- No complete draft has been exchanged
- Financial schedules are still being assembled
- The other person does not yet have separate counsel
- Substantive changes are still being negotiated
When delay becomes part of the evidence
The closer the first serious draft is to the ceremony, the harder it becomes to separate negotiation from wedding pressure.
The statute supplies a minimum final-agreement interval. It does not replace disclosure, meaningful review, negotiation, translation when needed, or time to understand the rights being changed.
Review the calendar and the draftWhat the agreement can and cannot do
A prenup can change financial rules. It cannot privately replace the court’s duties to children.
Support terms face a separate test.
A spousal-support provision is not enforceable against an unrepresented party and remains subject to unconscionability review when enforcement is sought.
Children remain outside private control.
A child’s right to support cannot be adversely affected, and custody decisions remain governed by the child’s best interests when the issue reaches court.
A defensible process before a signature
Build the agreement in four stages.
The goal is a clear financial plan created with enough information and time that both people can make an informed choice.
- 01
Define the financial goals
Identify property, businesses, debts, income, estate plans, support concerns, and the default rules the couple wants to change.
- 02
Exchange the financial picture
Assemble accurate schedules and supporting information so the agreement is negotiated against real assets and obligations.
- 03
Draft and review separately
Write precise terms, give the other person meaningful review time, and use independent counsel where rights or support terms require it.
- 04
Finalize without ceremony pressure
Resolve substantive revisions before the statutory final-agreement interval and preserve the signed agreement, disclosures, and review record.
A strong prenup is not a threat to marriage. It is a documented financial plan built before pressure replaces choice.
Bring the information that turns a generic document into your financial plan.
You do not need all six before calling. Do not send confidential records until the firm explains a secure way to share them.
Three assumptions that create avoidable disputes
The conversation may feel awkward. Leaving the terms undefined can be worse.
“Asking for a prenup means I expect divorce.”
The agreement is a financial-planning decision. Starting early allows the couple to discuss expectations before a conflict or wedding deadline controls the conversation.
“We are not wealthy enough to need one.”
Debt, a home, retirement, future earnings, a business, children from another relationship, or an expected inheritance can create important planning questions without celebrity wealth.
“An online template covers the basics.”
A template cannot identify the rights changed by your facts, correct missing disclosure, negotiate with separate counsel, or establish that the process was voluntary.
Questions before drafting or signing
California prenuptial agreement FAQ.
What makes a California prenup enforceable?
Writing and signatures are required. Voluntariness, timing, counsel or a proper waiver, disclosure, capacity, language comprehension, and the surrounding circumstances can all matter under Family Code section 1615. A court decides enforceability when challenged.
What is California’s seven-day rule?
For agreements executed on or after January 1, 2020, the party against whom enforcement is sought must receive the final agreement at least seven calendar days before signing, regardless of representation. This is a minimum interval, not a complete drafting schedule.
Do both people need separate lawyers?
Section 1615 permits a separate written waiver after advice to seek independent counsel, but unrepresented parties face additional information requirements. A spousal-support provision cannot be enforced against a party who lacked independent counsel when signing.
What can a prenup address?
It may address property rights, management and control, disposition on separation, divorce or death, estate arrangements, life-insurance death benefits, governing law, and other lawful personal or financial matters.
Can it decide child support or custody?
It cannot adversely affect a child’s support rights. Future custody and parenting decisions remain subject to the child’s best interests rather than the couple’s premarital instructions.
When should we begin?
Begin well before the wedding. Disclosure, drafting, independent review, negotiation, and revisions should occur before the final seven-calendar-day interval. The right schedule depends on complexity and cooperation.

The Definitive Guide to
Prenuptial & Postnuptial Agreements
The agreement you hope you never need.
The one you’ll be grateful you have.
A complete legal reference for prenuptial and postnuptial agreements in Temecula, Hemet, and Riverside County. What makes a prenup enforceable under California law, the mandatory 7-day rule, what you can and cannot include, spousal support waivers, postnuptial differences, common mistakes that void agreements, and the drafting process from start to finish.
◆ Executive Summary
The Canonical Answer
A prenuptial agreement (premarital agreement) is a written contract between two people who are about to marry, governing their property rights, debts, and support obligations in the event of divorce or death. If you are searching for a prenuptial agreement lawyer in Hemet, this guide explains the same Riverside County drafting and enforceability rules that control those cases. In California, prenups are governed by the Uniform Premarital Agreement Act (FC §1600–1617). To be enforceable, the agreement must meet strict requirements under FC §1615: both parties must sign voluntarily, with full financial disclosure, and the party against whom enforcement is sought must have had independent legal counsel or expressly waived it in writing. California’s mandatory 7-day rule (FC §1615(c)(2)) requires at least 7 calendar days between presentation and signing. A prenup can address property characterization, debt allocation, spousal support, inheritance rights, and business protection — but cannot waive child support or limit child custody. Spousal support waivers require independent counsel and are subject to an unconscionability review at enforcement (FC §1612(c)). Postnuptial agreements (signed after marriage) are governed by different rules, including the transmutation statute (FC §852) and heightened fiduciary duties between spouses. This guide explains every requirement, every permitted provision, and every mistake that can void an agreement in Riverside County.

California courts examine the agreement and the process behind it. Timing, voluntariness, counsel, disclosure, capacity, and the surrounding circumstances can determine whether challenged terms are enforced.
What Makes a Prenup Enforceable
FC §1615 — The Six Requirements
California imposes some of the strictest enforceability requirements in the country for prenuptial agreements. As the attorneys at Family Law Matters explain to every client, a prenup is only as strong as its compliance with FC §1615. Timing, counsel or a proper waiver, disclosure, capacity, language comprehension, and voluntariness can become disputed years later when enforcement matters most.
01
Written & Signed
The agreement must be in writing and signed by both parties.
Oral prenuptial agreements are not enforceable in California.
Both signatures must be voluntary — obtained without
duress, fraud, or undue influence (FC §1615(a)(1)).
02
Independent Legal Counsel
The party against whom enforcement is sought must have been
represented by independent legal counsel at the time of signing,
or must have expressly waived counsel in a separate
signed writing after being advised to seek an attorney
(FC §1615(c)(1)). Without counsel, spousal support waivers
are automatically unenforceable (FC §1612(c)).
03
The 7-Day Rule
At least 7 calendar days must pass between
the date the final agreement is first presented to the party
and the date they sign, for agreements executed on or after
January 1, 2020, regardless of whether the party has counsel
(FC §1615(c)(2)). This is a hard rule — it cannot be waived.
Presenting a prenup 6 days before the wedding is too late.
04
Full Financial Disclosure
Both parties must make a full, fair, and reasonable disclosure
of all property, financial obligations, and income —
or the right to disclosure must be expressly waived in writing
(FC §1615(a)(2)). Hidden assets, undisclosed debts,
or misrepresented income can void the entire agreement.
05
No Unconscionability
The agreement cannot be unconscionable at the time it was signed.
An unconscionable agreement is one so one-sided that no reasonable
person would agree to it — for example, one party waives
all property rights while the other retains everything.
The party claiming unconscionability bears the burden of proof.
06
Informed Understanding
If the party did not have independent counsel, they must have been
“fully informed of the terms and basic effect of the agreement”
as well as the rights being waived (FC §1615(c)(3)).
The agreement should include a plain-language summary
and an acknowledgment of understanding.
Requirement
Always Required
Writing, signatures, voluntariness, timing, counsel or a proper waiver,
disclosure, capacity, and the surrounding facts all matter. Section 1615
supplies the legal tests; a court decides enforceability when challenged.
MANDATORY · FC §1615
Counsel
Independent Counsel or Written Waiver
Each party should have their own attorney. If one party declines counsel,
they must sign a separate written waiver acknowledging the advice to seek
representation. But note: without counsel, spousal support provisions
are automatically unenforceable.
COUNSEL CRITICAL · FC §1612(c)
Exception
Child Support Cannot Be Waived
No prenuptial agreement can limit or waive child support (FC §1612(b)).
Child support is the right of the child, not the parent.
Any provision attempting to restrict child support is void and unenforceable.
VOID · FC §1612(b)
For agreements executed on or after January 1, 2020, the final agreement must be presented at least seven calendar days before signing, regardless of representation.

What a Prenup Can & Cannot Include
FC §1612 — Permitted Provisions
California law broadly allows prenuptial agreements to address property rights, debts, spousal support, and other financial matters. As the attorneys at Family Law Matters emphasize, a well-drafted prenup is not about “winning” the divorce before it happens — it is about establishing clear, agreed-upon rules that eliminate ambiguity, reduce conflict, and protect both parties.
Property Characterization
Define what is separate property and what becomes community property.
Override California’s default community property rules.
Protect pre-marital assets, family inheritances, and gifts from being
divided as community property in a divorce. Specify how property
acquired during the marriage will be classified.
Business Protection
Shield a pre-existing business from community property claims.
Specify that the business and its appreciation remain the owner’s
separate property. Address the community’s potential reimbursement
claim for the non-owning spouse’s labor contributions
(the Pereira/Van Camp analysis). Establish valuation methodology in advance.
Spousal Support Terms
Waive, limit, or define spousal support (alimony) in advance.
Set caps, duration limits, or step-down schedules.
The party against whom a support term is enforced must have had
independent counsel when signing (FC §1612(c)).
The provision also remains subject to unconscionability review when
enforcement is sought.
Debt Allocation
Protect yourself from a spouse’s pre-marital debts (student loans,
credit cards, business liabilities). Specify that each party remains
responsible for their pre-existing obligations. Define how debts
incurred during the marriage will be allocated in a divorce.
Inheritance & Estate Rights
Modify or waive rights to inherit from each other’s estates.
Protect family wealth, trusts, and generational assets.
Coordinate the prenup with estate planning documents (wills, trusts,
beneficiary designations) to ensure a unified strategy.
Real Estate & Retirement
Clarify ownership of the family home, investment properties, and real estate
purchased before or during the marriage. Address how retirement accounts
(401(k), IRA, pension) will be treated — which portion is separate
property and what growth during the marriage is community.
What a Prenup Cannot Do
Prohibited
Waive or Limit Child Support
Child support is the right of the child, not the parent.
No prenuptial agreement can waive, limit, cap, or modify child support
obligations (FC §1612(b)). Any provision that attempts to do so
is void and unenforceable. The court will calculate child support
under the guideline formula (FC §4055) regardless of what the prenup says.
Prohibited
Determine Child Custody
Custody is determined at the time of separation based on the child’s
best interests (FC §3011). A prenup cannot pre-determine who gets custody,
set a visitation schedule, or restrict either parent’s custody rights.
The court has exclusive jurisdiction over custody and will not defer
to a prenuptial agreement.
Prohibited
Include Non-Financial “Lifestyle” Clauses
Clauses penalizing weight gain, mandating household chores,
requiring a certain frequency of intimacy, or imposing lifestyle
restrictions are not enforceable in California. Prenups are financial
contracts — they govern property, debts, and support.
“Infidelity clauses” are also generally unenforceable
because California is a no-fault divorce state.
Prohibited
Violate Public Policy
Any provision that violates California public policy is void.
This includes provisions that encourage divorce, penalize a party
for seeking divorce, attempt to limit the court’s jurisdiction,
or create incentives for one party to behave in a way that is
detrimental to the marriage or the children.
| Category | Permitted? | Notes |
|---|---|---|
| Property characterization | Yes | FC §1612(a)(1) — separate vs. community |
| Debt allocation | Yes | FC §1612(a)(1) — pre-marital and during marriage |
| Spousal support waiver | Yes (with restrictions) | FC §1612(c) — requires counsel, unconscionability review |
| Business protection | Yes | Classify business as separate, address appreciation |
| Inheritance / estate rights | Yes | FC §1612(a)(1) — waive or modify |
| Life insurance requirements | Yes | Require policies as security for support obligations |
| Child support | No | FC §1612(b) — void and unenforceable |
| Child custody | No | Court has exclusive jurisdiction (FC §3011) |
| Lifestyle clauses | No | Not enforceable in California |
Spousal Support Provisions
The Most Litigated Provision in a Prenup
Spousal support waivers are the single most challenged provision in California prenuptial agreements. As the attorneys at Family Law Matters advise, a spousal support waiver that is technically valid when signed can still be overridden by the court if it would be unconscionable at the time of enforcement. This makes drafting spousal support provisions both the most valuable and the most delicate part of a prenup.
Requirement
Independent Counsel Mandatory
Under FC §1612(c), any provision waiving or limiting spousal support
is automatically unenforceable if the party against whom
it is enforced did not have independent legal counsel at the time of signing.
This is a bright-line rule — no exception, no waiver.
NO COUNSEL = UNENFORCEABLE
Review
Unconscionability at Enforcement
Even with counsel, the court reviews the spousal support provision
at the time of divorce. If enforcing it would be unconscionable
given the circumstances at divorce — not at signing —
the court can modify or override it. Circumstances that changed
dramatically (career sacrificed, serious illness, disability) matter.
CASE-BY-CASE · FC §1612(c)
Strategy
Alternatives to Full Waiver
Rather than a complete waiver (which invites challenge), consider
a cap on support amount, a declining schedule tied to marriage duration,
or a formula-based approach. Agreements that are fair but limited
are far more likely to survive unconscionability review than total waivers.
STRUCTURED LIMITS · BEST PRACTICE
Approach A
Complete Waiver
Both parties waive all spousal support. Simple and clear,
but the most vulnerable to challenge at enforcement.
Works best for short marriages where both parties have
comparable earning capacity and no children.
Risk: High if circumstances change dramatically.
Requires independent counsel for both parties.
Approach B
Cap & Duration Limit
Support is capped at a specific amount (e.g., $3,000/month)
and limited in duration (e.g., one year of support for every
two years of marriage). Provides a reasonable safety net
while limiting exposure for the higher-earning spouse.
Risk: Moderate. Much more likely to survive unconscionability review.
Recommended for most cases.
Approach C
Declining Schedule
Support decreases over time — for example, $5,000/month
for the first year, $3,000 for years 2–3, then terminates.
Incentivizes self-sufficiency while providing transition support.
Tied to a percentage of income at the time of separation.
Risk: Lower. Courts view declining schedules favorably.
Best combined with a career-sacrifice escalator.
The strongest spousal support provisions are those that are fair to both parties at the time of signing and include built-in adjustments for changes in circumstances. A provision that leaves one spouse unable to meet basic needs after a 20-year marriage where they raised children full-time will not survive judicial review — regardless of what was agreed.

Free Consultation →Postnuptial Agreements
After the Wedding — Different Rules Apply
A postnuptial agreement is signed after the marriage has already taken place. While it addresses many of the same issues as a prenup, it is governed by different legal rules — most significantly the transmutation statute (FC §852) and the fiduciary duties that exist between spouses (FC §721). As the attorneys at Family Law Matters explain, postnuptial agreements receive greater judicial scrutiny than prenups because of the inherent trust relationship between married spouses.
| Factor | Prenuptial Agreement | Postnuptial Agreement |
|---|---|---|
| When Signed | Before marriage | During marriage |
| Governing Law | UPAA (FC §1600–1617) | General contract law + FC §850–853 |
| 7-Day Rule | Yes — mandatory | No statutory requirement (but advisable) |
| Transmutation Rules | Not applicable | FC §852 requires express written declaration |
| Fiduciary Duties | Arm’s-length transaction | Highest good faith required (FC §721) |
| Judicial Scrutiny | Standard | Heightened — presumption of undue influence |
| Burden of Proof | Challenger must prove invalidity | Advantaged spouse may need to prove fairness |
FC §852 — Transmutation
When a postnuptial agreement changes property from community to separate
(or vice versa), it must comply with the transmutation statute:
the change must be made by an express declaration in writing
that is accepted by the spouse whose interest is adversely affected.
A general statement is insufficient — the writing must specifically
identify the property being transmuted.
FC §721 — Fiduciary Duty
Spouses owe each other the highest duty of good faith and fair dealing
(FC §721). In a postnuptial agreement, the spouse who benefits from
the agreement may bear the burden of proving that it was entered into
freely and with full understanding. This is the opposite of the prenup context,
where the challenger bears the burden.
When to Use a Postnup
Common triggers: one spouse starts a business during the marriage,
a significant inheritance is received, the marriage is in trouble
and the parties want to define terms before deciding on divorce,
or the parties simply did not execute a prenup before the wedding
and now want the same protections.

Common Mistakes That Void Prenups
Every Mistake Is a Future Argument for Invalidation
A prenup is only challenged when a marriage ends — often years or decades after signing. As the attorneys at Family Law Matters warn, the spouse who wants out of the prenup will scrutinize every procedural detail. A single defect that seemed minor at signing can void the entire agreement at the worst possible moment.
Fatal
Last-Minute Presentation
Presenting the prenup days before the wedding — or worse,
the night before — violates the 7-day rule and creates
a strong argument for duress. The implicit message is
“sign or the wedding is off,” which courts treat
as coercion. Start the process at least 2–3 months before the wedding.
Fatal
No Independent Counsel
Using one attorney for both parties is a critical error.
The attorney cannot represent both sides — it is an inherent
conflict of interest. Each party must have their own attorney,
or the non-represented party must sign an express written waiver.
Without counsel, spousal support waivers are automatically void.
Fatal
Incomplete Financial Disclosure
Hiding assets, undervaluing businesses, or omitting debts
gives the other party a powerful argument to void the entire
agreement. Disclosure must be comprehensive — bank accounts,
investments, real estate, business interests, retirement accounts,
debts, and income. Attach financial statements as exhibits.
Risky
Extreme One-Sidedness
An agreement where one party waives everything and the other retains
everything is vulnerable to an unconscionability challenge.
Courts look at the overall fairness of the agreement —
if it shocks the conscience, it may be voided even if all
procedural requirements were met.
Risky
Boilerplate / Template Agreements
Online templates and generic forms do not account for California’s
specific requirements (7-day rule, independent counsel, FC §1612/1615).
They frequently include unenforceable provisions (child custody,
lifestyle clauses) and omit required procedural safeguards.
A template prenup is a false sense of security.
Risky
Failure to Update
A prenup drafted 15 years ago may not reflect current assets,
children born during the marriage, career changes, or new businesses.
While the original agreement remains valid if properly executed,
outdated provisions may be challenged as unconscionable at enforcement.
Consider amending the prenup as circumstances change.
The Drafting Process
Start Early — The Statutory Minimum Is Not the Drafting Schedule
A properly drafted prenup requires time — for financial disclosure, attorney review, negotiation of terms, and the mandatory 7-day period. The necessary lead time depends on the assets, disclosure, negotiations, independent review, and revisions. Starting well before the wedding helps keep ceremony pressure from becoming part of a later voluntariness dispute.
01
Initial Consultation
Meet with your attorney to discuss your goals, assets, debts,
business interests, and concerns. The attorney explains California’s
community property system, what a prenup can and cannot do,
and develops a strategy tailored to your situation.
02
Full Financial Disclosure
Both parties compile comprehensive financial disclosures —
all assets, debts, income, business interests, retirement accounts,
and real estate. This documentation is attached as exhibits to the agreement.
Fair, reasonable, and full disclosure is the safer course. Section 1615
also addresses express written waiver and adequate knowledge, so the effect
of a disclosure dispute depends on the statutory test and facts.
03
Draft the Agreement
Your attorney drafts the prenuptial agreement based on your goals
and the financial information provided. The draft addresses property
characterization, debt allocation, spousal support terms,
business protection, inheritance rights, and any other agreed provisions.
04
Independent Counsel Review
The draft is sent to your fiancé’s independent attorney for review.
The other attorney advises their client on the terms, identifies
unfavorable provisions, and proposes modifications. This back-and-forth
negotiation takes as long as the issues require. Separate representation
supports meaningful review, and spousal-support terms have an express
independent-counsel requirement for the party against whom enforcement is sought.
05
Negotiate & Finalize
Both attorneys negotiate on behalf of their clients until mutually
acceptable terms are reached. The final agreement is prepared with
all exhibits (financial disclosures, property schedules).
The final version is presented to the non-drafting party,
starting the mandatory 7-day clock.
06
Sign After 7+ Days
At least 7 calendar days after the final agreement is presented,
both parties sign in the presence of their respective attorneys.
Include certificates of independent counsel, acknowledgments of
disclosure, and confirmation of voluntary execution. Notarization
is not required but is recommended for additional protection.
Planning Sequence
Goals + Disclosure + Drafting + Separate Review + Final Seven-Day Interval
Start early enough for complete financial schedules, considered drafting,
independent review, substantive negotiation, and a final version delivered
before the statutory signing interval begins.
For current agreements, the seven-calendar-day period runs from first presentation of the final agreement to signing, regardless of whether the party is represented.

Already Married? A Postnup Uses a Different Legal Framework.
Spouses may consider a postnuptial agreement, but fiduciary duties, transmutation rules, consideration, fairness, and the specific terms require a separate analysis from a premarital agreement.
Discuss Your Options →Definitions Glossary
Prenuptial Agreement (Premarital Agreement)
A written contract between two people who intend to marry, governing their property rights, debts, and support obligations in the event of divorce or death. Governed by the UPAA (FC §1600–1617).
Postnuptial Agreement
A written agreement between spouses entered into after marriage. Governed by general contract law and the transmutation statute (FC §850–853). Subject to heightened fiduciary scrutiny under FC §721.
UPAA (Uniform Premarital Agreement Act)
California’s statutory framework for prenuptial agreements (FC §1600–1617). Establishes the requirements for enforceability, permitted provisions, and grounds for voiding a prenup.
7-Day Rule (FC §1615(c)(2))
For agreements executed on or after January 1, 2020, the party against whom enforcement is sought must receive the final agreement at least seven calendar days before signing, regardless of representation. Separate advice-to-seek-counsel timing also applies under FC §1615(c)(1).
Independent Legal Counsel
Each party’s own separate attorney who advises them on the prenup’s terms, effect, and their rights. Required for enforceable spousal support waivers (FC §1612(c)). One attorney cannot represent both parties.
Unconscionability
A legal standard meaning the agreement is so one-sided that no reasonable person would agree to it. Grounds for voiding a prenup at signing or overriding spousal support provisions at enforcement (FC §1615(a)).
Transmutation (FC §852)
The legal process of changing property from community to separate (or vice versa) during marriage. Requires an express written declaration accepted by the adversely affected spouse. Critical for postnuptial agreements.
Fiduciary Duty (FC §721)
The highest duty of good faith and fair dealing that spouses owe each other. In postnuptial agreements, the advantaged spouse may bear the burden of proving the agreement was entered into freely and fairly.
Community Property
Property acquired during marriage through the labor or effort of either spouse. Presumed to be equally owned (50/50) and divided equally in divorce under FC §2550. A prenup can override this default rule.
Separate Property
Property owned before marriage, acquired by gift or inheritance during marriage, or earned after the date of separation. Confirmed to the owning spouse in divorce (FC §770). A prenup can expand or restrict this classification.
Pereira / Van Camp Analysis
Two competing formulas used to determine the community’s interest in a separate property business that appreciated during the marriage. Pereira allocates a fair return on investment as separate and the rest as community. Van Camp allocates reasonable compensation for labor as community and the rest as separate. A prenup can specify which method applies.
Duress
Coercion that overcomes the free will of a party. A prenup signed under duress is void. Classic example: presenting the prenup hours before the wedding with the implicit threat that the wedding will not proceed unless the other party signs.
Full Financial Disclosure
A fair, reasonable, and full accounting of property and financial obligations. FC §1615(a)(2) evaluates disclosure together with written waiver, adequate knowledge, and unconscionability when enforcement is challenged.
Sunset Clause
A provision that causes the prenup (or specific provisions) to expire after a certain number of years of marriage. For example, a sunset clause might void the entire prenup after 15 years, converting the marriage to standard community property rules.
