Postnuptial Agreement Attorney in Northridge

A Certified Family Law Specialist Drafting Postnuptial Agreements That Can Hold Up

Marriage doesn’t pause financial life, and circumstances change. A postnuptial agreement is a written contract entered into by two spouses after they’re already married, governing how assets, debts, property, and spousal support can be handled if the marriage ends. At Joel S. Seidel & Associates, our postnuptial agreement attorneys in Northridge bring over 60 years of combined family law experience and a Certified Family Law Specialist on the team. We don’t just draft the document. We draft it with a clear view of how it can perform if the marriage later dissolves.

Joel S. Seidel has held the Certified Family Law Specialist designation from the State Bar of California Board of Legal Specialization since 2004, a credential held by roughly 1% of California attorneys. His collaborative team approach means associates trained by leading law firms work alongside him on every case.

What a Postnuptial Agreement Can Cover

California’s community property default treats assets and income acquired during marriage as equally owned by both spouses. A valid postnuptial agreement can override that default across a wide range of financial matters.

Common subjects include:

• Property characterization: Designating specific assets as separate or community property, including transmutation under Family Code §852, which allows spouses to convert community property to separate property or vice versa through a written agreement
• Business interest protection: Under California community property law, the increase in value of a business during marriage may become subject to division without a written agreement addressing it
• Debt allocation: Assigning responsibility for existing or future debts between spouses
• Spousal support terms: Establishing, limiting, or waiving spousal support obligations in the event of divorce
• Inheritance and estate planning: Coordinating property rights with estate planning goals, including protections for children from a prior relationship

One firm boundary: a postnuptial agreement cannot predetermine child custody or child support. California courts retain jurisdiction over those issues based on the child’s best interests at the time a dispute arises.

Why Postnuptial Agreements Face Stricter Scrutiny Than Prenups

Postnuptial agreements face stricter judicial scrutiny than prenuptial agreements, and the reason is statutory. Family Code §721 imposes a fiduciary duty between married spouses that doesn’t apply to parties entering a prenuptial agreement before marriage. Because spouses owe each other the highest duty of good faith and fair dealing, courts examine the circumstances of a postnuptial agreement’s execution with particular care.

For a postnuptial agreement to be enforceable in California, it must be:

• In writing and signed by both spouses
• Notarized (not a statutory requirement, but strongly recommended and standard practice)
• Entered into voluntarily, free of duress, coercion, or undue influence
• Supported by full financial disclosure of all assets, income, debts, and liabilities by both parties
• Not unconscionable in its terms

Independent legal counsel is strongly recommended for both spouses. For any agreement that waives or limits spousal support, independent counsel for the waiving spouse is required. Without it, that provision may not be enforced. Unlike prenuptial agreements, which carry a mandatory seven-day waiting period under Family Code §1615, postnuptial agreements have no statutory waiting period. Rushed execution, however, increases vulnerability to challenge on grounds of duress. Full financial disclosure is the most common reason postnuptial agreements are invalidated: omitting or concealing assets can void the entire agreement.

Reasons Northridge Couples Consider a Postnuptial Agreement

Couples don’t need to be considering divorce to benefit from a postnuptial agreement. It can serve as a proactive financial planning tool at any stage of marriage. Common circumstances include:

• A significant change in financial circumstances, such as launching a business, receiving an inheritance, or a major career shift
• One spouse leaving the workforce to raise children or support the other’s career
• A desire to protect assets for children from a prior relationship
• Correcting or supplementing an existing prenuptial agreement that no longer reflects the couple’s situation
• Addressing concerns about financial transparency and establishing mutual clarity

A postnuptial agreement can reduce sources of financial uncertainty and give both spouses a clearer picture of where they stand, without waiting for a dispute to force the conversation.

How We Approach Postnuptial Agreement Matters

Our process begins with a consultation to understand each client’s circumstances and goals. From there, Joel S. Seidel and his associates work together to develop a strategy tailored to the couple’s specific financial picture. That process typically involves full financial disclosure by both parties, drafting and negotiation of terms, independent review by each party’s counsel, and properly witnessed and notarized execution.

We handle the sensitive financial negotiations that arise between spouses during drafting, working to produce an agreement designed to reduce future challenges. Because our practice covers the full scope of family law, including enforcement and challenge proceedings, we understand not just how an agreement reads at signing but how it can hold up if it’s ever tested.

Local Court Experience in the San Fernando Valley

Family law cases for Northridge residents are typically heard at the Van Nuys Courthouse, part of the Los Angeles Superior Court. Familiarity with local court procedures and judicial expectations is a practical advantage that carries through from drafting to any future proceeding. Our team has handled published appellate cases reversing judicial officers, which reflects the depth of experience clients draw on when they work with us.

Joel S. Seidel has been recognized by Super Lawyers in 2025. We serve clients in Northridge, Granada Hills, Chatsworth, Sherman Oaks, Porter Ranch, and throughout the San Fernando Valley.
