If you’re getting married and the words “prenuptial agreement” have come up, you’re probably picturing something out of a movie — a cold, unromantic document that assumes the marriage is doomed from the start. In reality, a well-drafted prenup (or its lesser-known cousin, the postnuptial agreement) is closer to insurance than a prediction. Most couples never need to pull it out. But for the ones who do, it can be the difference between a straightforward, private resolution and a long, expensive fight.
Here’s what these agreements can actually do under Texas law, what they can’t, and how to know if one makes sense for you.
Prenuptial vs. Postnuptial: What’s the Difference?
A prenuptial agreement (or “premarital agreement,” which is the term Texas law actually uses) is signed before the wedding. A postnuptial agreement covers the same ground but is signed after the marriage has already taken place. Texas recognizes both, and the legal standards for writing, signing, and enforcing them are very similar.
Postnups tend to come up in a few common situations: a couple who didn’t get around to a prenup before the wedding and wants to put something in place now, spouses who’ve received an inheritance or started a business since marrying and want to formally protect it as separate property, or a couple working through a rough patch who wants to clarify financial expectations going forward as part of rebuilding trust.
What Texas Law Requires to Make One Valid
Texas has adopted a version of the Uniform Premarital Agreement Act, and courts take the formal requirements seriously. To hold up, an agreement generally needs to meet a few conditions:
- In writing and signed by both parties. Texas does not recognize oral or “we agreed on it” prenups — no exceptions.
- Entered into voluntarily. If one spouse can show they were pressured, rushed, or coerced into signing, a court can throw the whole agreement out.
- Fair and reasonable disclosure of assets and debts. Both spouses need a genuine picture of what the other person owns and owes before they sign. An agreement built on hidden assets is an agreement asking to be challenged later.
- Not unconscionable at the time it was signed. Courts won’t enforce terms that were so one-sided or unfair that no reasonable person would have agreed to them with full knowledge of the facts.
Practically speaking, the agreements most likely to survive a challenge are the ones where both spouses had their own attorney, disclosed their finances honestly, and signed with plenty of time before the wedding — not the night before, under pressure, with a deadline looming.
What a Prenup or Postnup Can Actually Control
Texas is a community property state, meaning property and income earned during the marriage is generally considered to belong to both spouses equally, regardless of whose name is on it. A premarital or marital agreement is one of the few tools that lets you opt out of some of those default rules. Done properly, it can address:
- Which assets stay separate property rather than becoming community property, and how that’s tracked over time
- How a business, professional practice, or ownership interest is treated if the marriage ends
- Whether spousal maintenance (Texas’s version of alimony) will be paid, and if so, how much and for how long
- How property acquired during the marriage will be divided
- Rights to life insurance proceeds or death benefits
- How inheritances or gifts from family are treated, which matters a lot for blended families or anyone expecting to inherit
This is especially worth considering if you’re entering a second marriage with kids from a prior relationship, own a business, are bringing significantly more assets or debt into the marriage than your spouse, or expect to receive an inheritance you want to keep protected for your children.
What It Can’t Touch
There’s one category these agreements cannot control no matter how they’re written: child custody and child support. Texas courts decide conservatorship and support based on the child’s best interest at the time, not on what two people agreed to years earlier, possibly before the child was even born. A clause trying to pre-decide custody or waive child support won’t be enforced — the court will simply ignore it and rule on those issues independently.
Agreements also can’t include anything that violates the law, and they generally can’t leave a spouse eligible for public assistance as a way of avoiding support obligations.
Getting It Right the First Time
The biggest risk with a DIY or template prenup isn’t that it’s illegal — it’s that it doesn’t hold up when it’s actually needed, usually years after it was signed, when memories of the circumstances have faded and the stakes are much higher. Having each spouse represented by their own attorney, making sure disclosure is documented, and giving the agreement time to breathe before the wedding date all go a long way toward making sure it does what you intended if you ever need it.
