Planning a wedding in San Diego is exciting — from choosing a venue with ocean views, finalizing menus, planning the guest list, music, and the list goes on… But amid all the fun details, one important topic often gets overlooked: the prenuptial agreement.

I know, it’s not nearly as glamorous as flowers or cake tastings. But a well-crafted prenup can give couples peace of mind and clarity, and in some cases, save years of financial stress down the road. Here’s what every couple in California should know about prenups, what they can (and can’t) do, and how the process works.

Why Talk About Prenups Now? It’s Peak Wedding Season

If it feels like everyone you know is getting married this time of year, you’re not wrong. I’m seeing an increase in clients come in requesting a prenup. In the U.S., May through October is peak wedding season. According to The Knot, October alone accounts for about 17% of weddings — making it the single most popular wedding month.

Here in San Diego, weddings can happen just about year round – in the spring and fall for cooler weather and beautiful coastal venues, and in the summer for something a little warmer. That means couples who are tying the knot soon should start prenup conversations early, before schedules (and attorneys’ calendars) get booked solid.

What A Prenup Can Do In California

A prenuptial agreement (prenup) is a contract you and your future spouse sign before you marry. Once the wedding happens, it becomes legally binding. In California, prenups can:

• Clarify property rights: Decide in advance what is separate property and what becomes community property.
  
• Address spousal support: You can agree to limit or waive spousal support, though courts will still review fairness.
  
• Protect businesses and assets: If one spouse owns a business, a prenup can protect it from division in a divorce.
  
• Handle debts: Keep one spouse’s debts from becoming the other’s problem.
  
• Coordinate with estate planning: Protect children from prior relationships or align with wills and trusts.

What A Prenup Cannot Do

Not everything is negotiable. California law places clear limits:

• Child support cannot be waived. Courts always retain the right to decide what’s best for children.
  
• Unfair or “one-sided” terms may be thrown out. Judges won’t enforce a prenup that is unconscionable.
  
• No last-minute agreements. California requires at least seven days between presenting the final draft and signing.
  
• No hiding assets. Both spouses must fully disclose finances.
  
• Public policy matters. A prenup can’t override certain legal protections or duties.

Benefits Of A Prenup

• Reduces stress and conflict if divorce happens.
  
• Protects premarital assets, family businesses, or inheritances.
  
• Shields spouses from each other’s debts.
  
• Helps couples talk openly about money before marriage.
  
• May save thousands in legal fees later.

Possible Drawbacks

• Can feel unromantic or signal “lack of trust.”
  
• May not anticipate big life changes (illness, career shifts, children).
  
• Costs time and money upfront — both parties usually need lawyers.
  
• Risk of being challenged later if requirements weren’t followed.

Who Might Not Need A Prenup?

A prenup isn’t for everyone. Couples with few assets, little debt, or those uncomfortable with the idea may decide it isn’t worth the strain. If discussing a prenup creates more conflict than clarity, it might not serve your relationship well.

The Process: How To Do A Prenup In California

Start early. Aim for at least 3–6 months before the wedding. The Uniform Premarital Agreement Act requires that at least 7 days must pass between the time the parties have the final version and signing… There is no mandatory 7 day (or any other minimum amount of time) window before the wedding, (parties can technically sign on their wedding day but usually do not want to do so).

• Full Disclosure between both spouses must share income, assets, and debts.
• Hire attorneys to represent both parties. Each person should have their own legal counsel (especially if spousal support is addressed).
• Draft, negotiate, review. Work out the terms together.
• Sign and notarize. Make it official.
• Keep copies safe. Store the agreement with your important documents.

Note: Post-nuptial agreements may be legally enforceable, however they are subject to extreme scrutiny…

Tips

• Book early. Just like venues and caterers, family law attorneys get busy during wedding season.
  
• Combine legal and financial planning. Consider consulting a financial advisor along with your attorney.
  
• Keep it collaborative. Some couples use mediation to avoid a combative process.
  

Connect with wedding professionals. Many local planners can recommend experienced San Diego family law attorneys for prenups.
