Family law: marital property agreements

Prenuptial Agreements in Texas

Prenuptial agreements in Texas let two people decide, before the wedding, how their property and income will be treated during the marriage and if it ends. Chapter 4 of the Family Code sets the rules. This page covers what an agreement can include, when a court will not enforce one, and agreements signed after marriage.

What counts as a premarital agreement under Chapter 4?

A prenuptial agreement in Texas is a written contract between two people who plan to marry, made in contemplation of the marriage and effective only once they marry. The Family Code calls it a premarital agreement. Texas adopted the Uniform Premarital Agreement Act as Subchapter A of Chapter 4, beginning at Section 4.001.

The formal requirements are short. Under Section 4.002, the contract has to be a written document carrying the signatures of both future spouses. No consideration is needed for it to bind them, so neither person has to hand over money or anything else of value to make the deal stick. Under Section 4.004, the agreement takes effect on the wedding day. If the wedding never happens, the agreement never takes effect.

Terms that prenuptial agreements in Texas may include

Section 4.003 of the Texas Family Code gives a couple broad room to settle, in advance, who owns what and what becomes of it if they separate, divorce or one of them dies. The same section reaches spousal support and life insurance proceeds.

  • Each person's rights and duties in property, no matter when or where it was obtained
  • Control and management of property, including buying, selling, using, transferring or mortgaging it
  • How property is divided on separation, divorce, death or another event
  • Changing or waiving spousal support
  • Signing wills, trusts or similar documents that put the agreement into effect
  • Who owns the proceeds a life insurance policy pays at death
  • Which state's law governs the agreement
  • Any other matter, including personal rights and obligations, that does not violate public policy or a criminal statute

One limit is absolute. Section 4.003(b) keeps a premarital agreement from reducing the support a child is owed. Child support is set under its own rules, whatever the parents signed before the wedding.

When will a Texas court refuse to enforce a premarital agreement?

Under Texas Family Code Section 4.006, a court sets a premarital agreement aside only when the spouse attacking it proves one of two things: the signature was not voluntary, or the terms were unconscionable at signing and that spouse was also kept from a fair picture of the other person's finances. The challenging spouse carries the burden of proof.

The two defenses in Texas Family Code Section 4.006(a)
DefenseWhat the challenging spouse must prove
Involuntary signatureThe spouse did not sign the agreement voluntarily.
Unconscionable without disclosureThe terms were unconscionable on the day of signing, and beforehand the spouse (1) was not given fair, reasonable information about the other person's property and financial obligations, (2) did not voluntarily and expressly waive further disclosure in writing, and (3) did not have, and reasonably could not have had, adequate knowledge of those finances.

Unconscionability is decided by the judge as a matter of law, not by a jury, and the defenses in Section 4.006 are the only defenses available. The statute focuses on voluntariness and financial disclosure. It does not set a signing deadline before the wedding and does not require each person to hire a separate attorney, so whether those steps make sense for a particular couple is a question to raise at a first appointment.

A premarital agreement can be changed after the wedding only in writing

Texas Family Code Section 4.005 allows a premarital agreement to be amended or revoked after the marriage only by a written agreement signed by both spouses. Like the original, the amendment or revocation is enforceable without consideration. A spoken promise to tear up the agreement does not change it.

  • Void marriage. If the marriage is later found void, Section 4.007 enforces the agreement only as far as needed to avoid an inequitable result.
  • Time limits. Under Section 4.008, a statute of limitations on a claim under the agreement is paused during the marriage, though equitable defenses such as laches and estoppel remain available.

Married couples can use partition, income and conversion agreements

Couples who are already married can sign what is often called a postnuptial agreement. Texas Family Code Chapter 4, Subchapter B, lets spouses split or swap community property so it becomes separate property, and to agree that income from separate property stays separate. Subchapter C allows the reverse: converting separate property into community property.

Partition or exchange
Under Section 4.102, spouses may divide existing or future community property so that each share becomes the receiving spouse's separate property. Section 4.103 lets them agree that income from separate property is also separate. Section 4.104 requires a signed writing for either kind, and Section 4.105 applies the same two defenses as a premarital agreement.
Conversion to community property
Under Section 4.203, the conversion document needs both spouses' signatures on paper, has to identify the property and state that it is being converted. Simply adding a spouse's name to a title is not enough. Section 4.205 presumes fair disclosure when the agreement carries a prominent statutory warning about the legal effect of conversion.

How a marital property agreement connects to divorce and support

A marital property agreement matters most when a marriage ends. It can change which property counts as separate in a divorce, limit or waive claims between the marital estates, and address spousal support, while child support stays protected by statute.

Prenuptial agreements in Texas: common questions

Do courts uphold prenuptial agreements in Texas once both people sign?

Upholding them is the default: under Section 4.002, a premarital agreement binds the couple once it is put in writing and signed, with no payment or other value required. A court will refuse to enforce it only if the challenging spouse proves one of the two defenses in Section 4.006: an involuntary signature, or an unconscionable agreement signed without fair financial disclosure.

If we have children later, does our prenup control their support?

It does not. Section 4.003(b) puts a child's support beyond the reach of any premarital agreement. Any child support is set under the Family Code's support rules, regardless of the agreement.

Could a premarital agreement take spousal support off the table?

It can. Section 4.003(a)(4) lets future spouses change or waive spousal support in advance. How such a provision applies in a particular divorce depends on its wording and the facts.

Can we still sign an agreement once we are already married?

Yes. Chapter 4, Subchapter B, lets married spouses divide community property so it becomes separate property, or agree that income from separate property stays separate, at any point in the marriage. Each of these agreements has to be a writing that both spouses sign.

Once we are married, can prenuptial agreements in Texas still be amended or revoked?

Yes, but only in writing. Section 4.005 allows a premarital agreement to be amended or revoked after marriage by a written agreement signed by both spouses, and no exchange of value is needed.
