Quick Answer: Under Family Code section 1615(c)(2)(B), for a prenup signed on or after January 1, 2020, the party against whom the agreement is later enforced must have had at least seven calendar days between first being presented with the final agreement and signing it. That applies whether or not the party has a lawyer. The advisement to seek independent counsel must also come at least seven calendar days before the final agreement is signed. If these requirements are not met, the court will deem the prenup involuntary, which makes it unenforceable against that party. The practical lesson is to start early and deliver the final version well before the wedding.
Many couples start thinking about a prenup a few weeks before the wedding, when venues are booked and calendars are full. California's seven-day rule is one of the most important timing requirements to understand. It is not about the wedding date. It is about the gap between the final agreement and the signature. Our prenuptial agreements page covers the rest of the prenup process.
What the Statute Says
Family Code section 1615(a) makes a prenup unenforceable if the challenging party proves they did not sign it voluntarily, or proves that it was unconscionable when signed and that they lacked fair, reasonable, and full disclosure of the other party's finances. Section 1615(c) then says the agreement is deemed involuntary unless the court finds, in writing or on the record, all of the following:
Independent counsel (1615(c)(1)). The party had independent counsel when signing, or, after being advised to seek independent counsel, expressly waived representation in a separate writing. The advisement must come at least seven calendar days before the final agreement is signed.
Seven days with the final agreement (1615(c)(2)). For agreements signed on or after January 1, 2020, the party had at least seven calendar days between first being presented with the final agreement and signing it, regardless of whether they had a lawyer. For agreements signed between January 1, 2002, and January 1, 2020, the seven days ran from being presented with the final agreement and advised to seek counsel. The current version came from AB 1380 (2019).
Unrepresented parties (1615(c)(3)). An unrepresented party was fully informed of the terms and basic effect of the agreement and the rights being given up, in a language they are proficient in, received that explanation in writing before signing, and signed a document acknowledging who provided it.
No duress, fraud, or undue influence, and capacity (1615(c)(4)).
Any other factors the court deems relevant (1615(c)(5)).
The seven-day requirement does not apply to nonsubstantive amendments that do not change the terms of the agreement.
What Counts as the "Final Agreement"?
This is where many timelines fail. Drafts exchanged during negotiation do not start the clock. The seven days run from when the party is first presented with the final agreement. If a substantive term changes on day five, for example a support provision or the treatment of a business, the safer course is to treat the revised version as a new final agreement and start a new seven-day period. Typo corrections and other nonsubstantive edits do not reset it.
Practical steps:
Keep a written record of when each version was delivered and to whom.
Label the final version clearly and confirm delivery by email.
Avoid substantive changes at the last minute.
Sign in front of counsel, with a record of the dates.
Why the Rule Exists
The Legislature added these requirements after In re Marriage of Bonds (2000) 24 Cal.4th 1, in which the California Supreme Court upheld a premarital agreement signed shortly before the wedding by a party who did not have her own lawyer, holding that lack of counsel was only one factor in judging voluntariness. In response, the Legislature amended section 1615, effective January 1, 2002, so that voluntariness depends on specific protections, including time to review and access to independent advice.
Spousal Support Provisions Need Extra Care
Family Code section 1612(c) provides that a spousal support provision, including a waiver, is not enforceable if the party against whom it is enforced was not represented by independent counsel when the agreement was signed, or if the provision is unconscionable at the time of enforcement. Having counsel does not, by itself, make an otherwise unenforceable support provision enforceable. In practice, both parties should have their own lawyers for any agreement that limits support. Section 1612(b) adds that a prenup cannot adversely affect a child's right to support.
What If You Miss the Seven Days?
If the final agreement is signed fewer than seven days after it was first presented, the court should deem it involuntary as to that party, and the agreement is then unenforceable against them. Options include:
Postpone the signing, even if it means moving a civil ceremony. A prenup must be signed before marriage to be a prenup.
Marry, then sign a postnuptial agreement. The seven-day rule in section 1615 does not apply to postnups, but postnups face fiduciary-duty scrutiny between spouses that is often tougher. See our posts on postnuptial agreements and the fiduciary duties spouses owe each other.
Narrow the agreement to terms both sides can review fully in the time available, and plan a later postnup for the rest. Any approach should be reviewed with counsel.
A Practical Timeline
The timeline below is illustrative, not advice for your situation:
3 to 6 months before the wedding: each partner retains independent counsel and the couple exchanges financial disclosures.
2 to 3 months before: the first draft is circulated and negotiated.
At least 30 days before: the final agreement is delivered, with a written record of the date.
No sooner than 7 full calendar days after delivery: signing, with counsel present.
Business owners and founders often need more time for disclosure and valuation questions. See our post on founder prenups. Couples signing a religious agreement alongside a civil prenup should coordinate both, as discussed in our post on halachic prenups.
Disclosure Still Matters
Timing is not the only requirement. Under section 1615(a)(2), a prenup can also be set aside if it was unconscionable when signed and, before signing, the challenging party did not receive fair, reasonable, and full disclosure of the other party's property and obligations, did not waive disclosure in writing, and did not have adequate knowledge of the other party's finances. Complete disclosure schedules attached to the agreement are standard practice.
Key Takeaways
Start Drafting Months Ahead
Begin talks at least three months before the wedding so negotiation does not run into the seven-day deadline.
Date Every Draft
Label and date each version so it is clear which document started the seven-day clock.
Keep Proof of Delivery
Save the email or receipt showing when the final agreement and the counsel advisement were delivered.
Sign Apart From Wedding Events
Signing at a rehearsal dinner or on the wedding day invites a later claim of pressure.
Frequently Asked Questions
How close to the wedding can you sign a prenup in California? There is no cutoff tied to the wedding date. The final agreement must be presented at least seven calendar days before signing, and the counsel advisement must also come at least seven days before. Starting months earlier is wise.
Does the 7-day rule apply if both of us have lawyers? Yes. For agreements signed on or after January 1, 2020, the seven days apply regardless of representation.
Does the 7-day rule apply to postnups? No. It is part of the premarital agreement statute. Postnups are governed by spousal fiduciary duties and the transmutation rules instead.
Can the 7-day requirement be waived? The statute does not provide for waiving the seven-day period. A prenup signed without it is deemed involuntary as to the party who did not have the time.
If you are planning a prenup, the calendar matters as much as the terms. To talk with Attorney Michael Geller about timing and drafting, call The Geller Firm at 415-840-0570 to schedule a consultation.
