What Can Be Covered in a Prenuptial Agreement
A prenuptial agreement generally protects each spouse’s financial assets and any property in the event of a dissolution, separation, or divorce. Additionally, they may provide a clear definition of what can and cannot be divided upon dissolution. Prenuptial agreements are an assurance that the division is predetermined, to avoid any further litigation on any disputed property or assets between the two spouses.
Generally, prenuptial agreements can outline:
- What is separate property and community property – a property that can be divided equally in the event of a divorce.
- Who has the legal right to control separate property.
- Which debts are assigned to whom, and what happens following divorce.
- How income and assets accumulated during marriage are to be divided upon dissolution.
A prenuptial agreement can also address any provisions for medical coverage, life insurance, and any inheritance rights. In San Mateo County, prenups often protect high-value Peninsula real estate, tech company stock options, business interests, and substantial retirement accounts accumulated before marriage.
What is Not Covered in a Prenuptial Agreement
A prenuptial agreement cannot address anything regarding your children’s rights. This includes matters of child custody and child support. Ultimately, the courts make these decisions, and will make a judgment based on the “best interests of the child” under Family Code §3011.

Other factors that may or may not be enforceable in a prenuptial agreement, depending on the court’s interpretation, include:
- Waivers of Spousal Support: The state of California generally allows these provisions, but may choose not to enforce them if the result is extremely unfair to one party.
- Promoting Dissolution: Any agreement that encourages divorce or alters generally accepted relationship duties may be invalidated.
- Unfair Terms: Overwhelmingly unfair terms in the agreement may fall under this umbrella.
Because these can be generally left up to interpretation by a court, it is highly recommended that your prenuptial agreement be thoroughly analyzed by a family law professional before you officially sign it.

Frequently Asked Questions
Are prenuptial agreements enforceable in California?
Yes, if properly drafted and executed, prenuptial agreements are legally enforceable in California under the Uniform Premarital Agreement Act (UPAA), codified in Family Code §1610–1617. Both parties must sign voluntarily, with full financial disclosure and adequate time to review the terms before marriage.
Do I need a lawyer to create a prenuptial agreement in San Mateo?
While not legally required, having an attorney ensures your agreement meets all California requirements and holds up in San Mateo County Superior Court. Each spouse should have independent legal counsel to avoid potential challenges based on coercion or unfairness.
What can a prenuptial agreement cover?
A prenup can outline how property, debts, and assets will be divided in the event of divorce or death. It can also include terms about spousal support and business ownership, provided they comply with state law and public policy.
What can't be included in a prenuptial agreement?
California law prohibits prenups from containing provisions about child custody, child support, or anything that violates public policy. Including illegal or unfair terms can make the entire agreement invalid under Family Code §1612.
How far in advance should we create a prenup before our wedding?
Ideally, you should begin the process several months before your wedding. California law under Family Code §1615 requires at least seven days between when one party receives the final draft and when it's signed.
Can a prenuptial agreement be changed after marriage?
Yes. Couples can modify or revoke a prenuptial agreement after marriage by creating a postnuptial agreement. Both spouses must agree to the changes in writing and meet the same legal standards required for a prenup under Family Code §1615.
What happens if we don't have a prenuptial agreement?
Without a prenup, California's community property laws under Family Code §760 determine how assets and debts are divided. This means most property acquired during the marriage will be split 50/50 between both spouses.
Can a prenuptial agreement protect my business or inheritance?
Yes. A prenup can preserve your ownership of a business, inheritance, or other separate property by keeping it distinct from marital assets. This is particularly important for Peninsula entrepreneurs and tech professionals with equity compensation.
