When Should You Update a Prenuptial Agreement in Maryland?

June 15, 2026 by Milstein Siegel

 

In This Article: Learn when to update a prenuptial agreement in Maryland and how a prenup attorney can help protect assets and establish legal enforceability

.


A prenuptial agreement is among the most useful legal instruments a couple can possess. It sets clear financial expectations before marriage, protects individual assets, and can help prevent costly disputes if the relationship changes. However, finalizing a prenup before the wedding doesn’t mean all the work is done.

Life changes. Careers grow. Children arrive. Inheritances land unexpectedly. Each of these developments can affect whether the agreement you signed years ago still reflects your current situation, or whether it would hold up in a Maryland court. Recognizing the right time to review the terms is equally important as possessing the document initially. 

Read on to explore the most common life events that signal it is time to update a prenuptial agreement in Maryland, how the modification process works, and why working with a qualified prenuptial agreement attorney in Maryland matters.

How Maryland Handles Prenuptial Agreement Modifications

Before getting into the triggers for an update, it helps to understand how Maryland law approaches these changes. Unlike many states, Maryland has not adopted the Uniform Premarital Agreement Act. Prenuptial agreements are instead governed by general contract law, with courts applying heightened scrutiny given the confidential nature of the marital relationship.

Under Maryland Family Law § 8-101 and related case law, spouses may modify a valid prenup after marriage, but any changes must be in writing and signed by both parties. Verbal agreements carry no legal weight. Courts will also expect full financial disclosure from both spouses, just as they did when the original agreement was signed. A family law attorney in Maryland can guide this process and protect the enforceability of any update.

Life Events That May Require an Update

Significant Changes in Income or Career

A prenuptial agreement written when one spouse had a modest income may look very different after they become a business owner or senior executive. Equally, if one partner leaves the workforce to raise children, the financial dynamics shift considerably.

When income changes substantially, the asset protection provisions in an existing prenup, including how marital versus non-marital property is classified, may no longer reflect either party’s intentions. A prenup modification in Maryland should address these changes before conflict arises.

Starting or Acquiring a Business

Business interests are among the most contested assets in a divorce. If you or your spouse launches a company, acquires equity, or buys into an existing business, your original agreement may not account for how that interest would be treated. Maryland courts regularly handle business valuation disputes, and updating the prenup to address ownership stakes and buyout terms can prevent significant complications later.

Purchasing Real Estate or Accumulating Major Assets

Buying a home, either jointly or individually, changes the property picture in ways a prenuptial agreement written years earlier may not have anticipated. The same principle applies to retirement funds, investment accounts, and other significant assets acquired after the marriage.

Updating a prenuptial agreement in Maryland to reflect these holdings creates a clearer record of what is marital versus non-marital property under Maryland Family Law § 8-201, which can prevent disputes later.

Having Children

In Maryland, courts do not enforce custody or child support agreements outlined in a prenuptial agreement, as such issues are addressed according to the child’s best interests at the time of the dispute. However, having children often prompts couples to revisit related financial matters, such as spousal support and how a stay-at-home parent’s contributions will be recognized. An updated prenup can address those realities in a way the original document likely did not.

Receiving an Inheritance or Gift

A large inheritance or gift can significantly change an individual’s financial standing. If those funds are commingled with marital assets, they may lose their non-marital character over time. Under Maryland Family Law § 8-201, property acquired by inheritance or gift from a third party is excluded from marital property, but only if it stays clearly separate. Working with a prenuptial agreement attorney in Maryland to update the agreement when a substantial inheritance is received helps protect that distinction.

When Maryland Law Changes

Family law does not stay static. Legislative updates and court rulings can affect whether specific prenup provisions remain enforceable. If several years have passed since signing, a review by a Maryland family law attorney is worth considering.

Consider a Postnuptial Agreement

If a couple wants to revise an existing prenup – or did not sign one before the wedding – a postnuptial agreement in Maryland is a recognized option. Maryland courts uphold these agreements as long as they adhere to the same criteria of fairness, transparency, and voluntary execution that apply to prenuptial agreements.
