Premarital/Prenuptial Agreements

Premarital Agreements in California — What Every Couple in San Diego Should Know

If you’re planning to get married in San Diego County, it’s the perfect time to consider a premarital agreement — also known as a prenuptial agreement or prenup. A well-drafted prenup can give both parties clarity, financial protection, and peace of mind before saying “I do.”

At Kosla & De Alba Family Law Attorneys, we help engaged couples across San Diego, Carlsbad, Encinitas, Vista, and Oceanside create legally sound premarital agreements that protect their assets and define their financial expectations under California law.

What Is a Premarital (Prenuptial) Agreement?

Under California Family Code §§ 1600-1617, a premarital agreement is a written contract entered into by two people before marriage that becomes effective upon marriage. It allows couples to set their own financial terms instead of relying solely on California’s community property laws, which automatically divide most property and debts acquired during marriage equally upon divorce.

A California premarital agreement gives couples the freedom to decide how property, income, support, and other financial matters will be handled — both during the marriage and if it ends.

Why Consider a Prenup in San Diego?

California is a community property state, meaning that without a valid premarital agreement, nearly all income and assets earned during marriage become joint property. A customized prenup allows you and your partner to opt out of the default community property system and design your own arrangement.

A carefully drafted San Diego prenuptial agreement can help you and your future spouse:

• Limit, eliminate, or modify spousal support (alimony) within the limits of Family Code § 1612(c)

• Protect separate property owned before marriage, including real estate, bank accounts, and investments

• Preserve potential inheritances or gifts intended to remain separate property

• Protect family-owned businesses or professional practices from division at divorce

• Safeguard retirement accounts, pensions, and stock options

• Establish expectations for payment of living expenses and financial responsibilities during the marriage

With proper planning, a prenup can clarify expectations, prevent future disputes, and strengthen your relationship through transparency and fairness.

Legal Requirements for a Valid California Prenup

California law imposes strict procedural requirements to ensure that premarital agreements are fair and enforceable. Common requirements include:

1. Written and signed agreement – Oral prenups are not valid under California law.

2. Voluntary execution – Both parties must enter the agreement freely and voluntarily.

3. Full financial disclosure – Each party must provide complete information about assets, income, and debts.

4. Independent legal counsel – Each party should have the opportunity to review the agreement with their own attorney.

5. Seven-day rule – There must be at least seven calendar days between the time a party receives the final version of the agreement and when it is signed.

6. No unconscionability – The agreement cannot be extremely unfair or leave one party without reasonable financial protection.

Failing to meet any of these conditions may cause a court to invalidate all or part of the agreement.

How a Prenuptial Agreement Can Be Customized

Premarital agreements in California are flexible and can be tailored to meet the couple’s goals. For example, a prenup can:

• Define how separate and community property will be treated

• Determine whether future income or appreciation of assets remains separate

• Set guidelines for spousal support or waive it under certain conditions

• Protect real estate interests (for example, keeping a premarital home separate)

• Allocate business ownership interests in the event of divorce or death

• Specify how debts and expenses are managed during marriage

A prenup can also serve as part of broader estate planning, ensuring that your wishes align with your will or trust.

Are Premarital Agreements Enforceable in San Diego Courts?

Yes — when properly drafted, a premarital agreement is fully enforceable under California law. Courts in San Diego County will uphold valid prenups that meet the statutory requirements and were executed fairly, with adequate disclosure and representation. However, agreements that are coerced, unfairly one-sided, or not properly executed are often challenged successfully in court.

That’s why working with an experienced San Diego family law attorney is essential to ensure that your agreement is enforceable and truly protects your interests.

When Should You Sign a Prenup?

Ideally, couples should begin discussing and drafting their premarital agreement at least two to three months before the wedding. Rushing the process may raise issues of duress or lack of voluntary consent. Taking the time to consult with counsel ensures both parties understand the terms and have the opportunity to negotiate fairly.
