|---|---|
| Writing, signature, and effect | Writing signed by both; no consideration; effective on marriage (§§ 4.002, 4.004) |
| Execution formalities | No notary, acknowledgment, witnesses, or recording required by the UPAA for basic validity (§ 4.002) |
| Financial disclosure and waiver | Fair and reasonable disclosure; written express waiver or adequate knowledge can defeat the disclosure-based challenge (§ 4.006(a)(2)) |
| Independent counsel and timing | No express counsel, counsel-waiver form, review period, or pre-wedding waiting period; voluntary signing still required (§§ 4.002, 4.006) |
| Fairness standard and source | Statute — involuntary signing defeats enforcement; unconscionability at signing plus all three disclosure failures also defeats it; statutory remedies/defenses are exclusive (§ 4.006) |
| Spousal-support limits | May modify or eliminate spousal support; no counsel gate or enforcement-time second look in the UPAA, but the general § 4.006 test applies (§§ 4.003(a)(4), 4.006) |
| Child and public-policy limits | Cannot adversely affect child support; custody/access remain subject to court-determined best interests; no term may violate public policy or a criminal statute (§§ 4.003, 153.002) |
| Amendment and revocation | After marriage, only by a writing signed by both; no consideration required (§ 4.005) |
Requirements one by one
Texas uses the Uniform Premarital Agreement Act
Tex. Fam. Code § 4.010 names Subchapter A the Uniform Premarital Agreement Act. It supplies the form, permitted subjects, enforcement test, and change rules for agreements between prospective spouses.
The basic form is a signed writing
Tex. Fam. Code §§ 4.002 and 4.004 require the agreement to be in writing and signed by both parties, make it enforceable without consideration, and make marriage—not the signature date—the event that activates it.
The UPAA adds no notary, witness, or filing requirement
Section 4.002 states the complete statutory formalities for the prenup itself: a writing and both signatures. Subchapter A does not add notarization, acknowledgment, witnesses, or recording as a condition of basic validity.
That is different from treating a notary or separate property instrument as a practical safeguard for a particular transaction. Those choices do not become universal UPAA requirements.
Disclosure uses alternatives, not one absolute format
The § 4.006(a)(2) route requires more than an omitted asset. The party resisting enforcement must prove that the agreement was unconscionable when signed and that all three listed facts applied before signing: no fair and reasonable disclosure, no voluntary express written waiver of further disclosure, and no actual or reasonably available adequate knowledge of the other party's property or financial obligations.
The statute does not require the waiver to be a separate document. It does require the waiver itself to be express, voluntary, and in writing.
Texas specifies no counsel or pre-wedding clock
Chapter 4 does not impose independent counsel, a counsel-advisement form, a review period, or a minimum number of days before the wedding. The absence of those formal requirements does not eliminate the separate requirement that the agreement be signed voluntarily under § 4.006(a)(1).
The statute supplies an exclusive enforcement test
Under § 4.006(a)-(c), an agreement is not enforceable if the resisting party proves either involuntary signing or the combined execution-time unconscionability and disclosure test. The court decides unconscionability as a matter of law.
Subsection (c) says these statutory remedies and defenses are exclusive, including against common-law remedies or defenses. The act does not add a general enforcement-time fairness or changed-circumstances review.
Spousal support may be modified or eliminated
Section 4.003(a)(4) expressly permits modification or elimination of spousal support. Texas's UPAA does not condition that term on independent counsel and does not add a support-specific unconscionability review at enforcement. The agreement as a whole remains subject to the exclusive § 4.006 test.
Child matters and public policy remain outside private control
Tex. Fam. Code § 4.003(a)-(b) says the agreement may not adversely affect a child's right to support. For custody, possession, and access, § 153.002(a) makes the child's best interest the court's primary consideration.
Section 4.003(a)(8) also limits personal-rights and other terms: they may not violate public policy or a statute imposing a criminal penalty.
Changes after marriage require another signed writing
Under § 4.005, a post-marriage amendment or revocation must be in writing and signed by both parties. No consideration is required for the change.
What trips people up
- “Fair and reasonable” is the Texas disclosure phrase. Section 4.006 does not use California's “fair, reasonable, and full” formulation.
- Marriage pauses a limitations period, but not every timing defense. Under § 4.008, an applicable limitations period is tolled during marriage while laches and estoppel remain available.
Common questions
Can a Texas prenup choose which state's law governs its construction?
Yes. Section 4.003(a)(7) includes a choice-of-law term among the subjects the parties may address. How a court resolves a multistate dispute remains a separate question beyond the face of that provision.
Can it address property at death and related estate arrangements?
Yes. Section 4.003(a) permits terms about property disposition at death, a will or trust arrangement used to carry out the prenup, and ownership or disposition of a life-insurance death benefit.
What if the marriage is determined to be void?
Tex. Fam. Code § 4.007 limits an agreement that otherwise would have been a premarital agreement to enforcement necessary to avoid an inequitable result.
