Why a postnuptial agreement is valuable even if you have a prenup

On Behalf of | May 21, 2025 | Divorce

Most everyone knows about prenuptial agreements. They’re becoming increasingly common for couples of all ages and income levels who are about to marry. Fewer couples, however, consider the value of a postnuptial agreement.

Whether a couple got a prenup before they married or not, putting a postnup in place can address the assets they’ve accumulated (separately and together) during the marriage. The only way to update a prenup is to get a postnup. Therefore, if a prenup is no longer relevant to a couple’s current lives and finances or if there are sections that could potentially be ruled invalid, getting a postnup is an important step towards continuing the protections initially addressed with the prenup.

A postnup can also help protect both spouses if their lives have gone in different directions than they anticipated when they married. For example, if one spouse ended up being a stay-at-home parent while the other built a successful business or medical practice, a postnup can address how much spousal support and property they’ll receive in a potential divorce.

An alternative to community property requirements

A postnup can be particularly valuable in California because it can help couples avoid the state’s community property law. Under California law, if a divorcing couple can’t negotiate their own property division agreement, the court is required to ensure that each spouse receives an equal amount of assets accumulated during the marriage.

In a postnup, a couple can detail how they want to divide all of their assets, regardless of what the law says. As long as it’s not an egregiously unfair division, a judge will typically approve it in a divorce.

A postnup can serve multiple purposes. Here, we’ve discussed just a few. As with a prenup, each spouse should have their own legal representation to help ensure that their rights and interests are protected.
