Most people call them “prenups,” but Texas law generally refers to premarital agreements (before marriage) and marital property agreements (after marriage). A well-drafted agreement can reduce uncertainty, protect important assets, and create clearer financial expectations—especially in Texas, where community property rules apply by default. The Talley Law Firm serves Friendswood and the Houston metro area, including Harris County, Galveston County, and Brazoria County.

Prenup vs. Postnup: what Texas law calls these agreements

Texas has a detailed statutory framework for these agreements in Texas Family Code Chapter 4 (“Premarital and Marital Property Agreements”).

Premarital agreement (“prenup”): an agreement between prospective spouses made in contemplation of marriage and effective on marriage. (See Tex. Fam. Code § 4.001(1), § 4.004.)
Marital property agreements (“postnups”): agreements between spouses after marriage, including partition/exchange agreements and agreements concerning income from separate property. (See Tex. Fam. Code §§ 4.101–4.105, 4.102–4.104.)
Agreements converting separate property to community: allowed with specific formalities and disclosures. (See Tex. Fam. Code §§ 4.201–4.206.)

Why couples consider prenups in Texas (community property context)

Texas is a community property state. In broad terms, property acquired during marriage is often presumed community property, and division in divorce is guided by “just and right” principles. A premarital agreement can set clearer rules in advance—particularly for separate property protection, debt allocation, business ownership, and how property is treated upon divorce or death.

What a Texas premarital agreement can cover (overview)

Chapter 4 allows couples to contract on a wide range of financial topics. Common categories include:

Rights and obligations in property of either or both parties (wherever located). (Tex. Fam. Code § 4.003(a)(1))
Management and control rights: buying/selling/using/encumbering property. (Tex. Fam. Code § 4.003(a)(2))
Disposition of property on separation, divorce, death, or other events. (Tex. Fam. Code § 4.003(a)(3))
Modification or elimination of spousal support (as allowed by law). (Tex. Fam. Code § 4.003(a)(4))
Estate planning coordination (wills/trusts/other arrangements). (Tex. Fam. Code § 4.003(a)(5))
Life insurance benefits ownership and disposition. (Tex. Fam. Code § 4.003(a)(6))

Important limitation: child support

A premarital agreement cannot adversely affect a child’s right to support. (Tex. Fam. Code § 4.003(b))

Business owners, professionals, and complex assets (LLCs, partnerships, trusts)

Many “prenup” disputes are really property characterization disputes—what is separate, what is community, and what happens to growth over time. That is especially true for:

Closely held businesses, professional practices, and family companies
LLC and partnership interests (including distributions, reinvestment, and management rights)
Real estate portfolios and reimbursement/tracing issues
Trust interests, inheritances, and family gifts

Formalities and enforceability (why process matters)

Texas requires key formalities. A premarital agreement must be in writing and signed by both parties, and it is enforceable without consideration. (Tex. Fam. Code § 4.002.)

As for enforceability, Chapter 4 provides specific standards and defenses. In general terms, a premarital agreement may be unenforceable if it was not signed voluntarily, or if it was unconscionable when signed and disclosure/waiver/knowledge requirements are not met. (Tex. Fam. Code § 4.006.) Courts decide unconscionability as a matter of law. (Tex. Fam. Code § 4.006(b).)

Start early: last-minute signing increases pressure arguments and risk.
Disclose clearly: clean disclosure reduces future litigation.
Independent counsel is recommended: it helps both parties make informed decisions and reduces future attacks on the agreement.
Draft precisely: ambiguity invites disputes; clarity prevents them.

Prenup (and postnup) process: what to expect

Consultation: goals, timelines, and risk points (property, debt, business, inheritance planning).
Information gathering: asset/debt lists, supporting documentation, and disclosure approach.
Drafting: clear terms aligned with your real-world priorities.
Review and revisions: questions addressed, revisions tracked, execution planned.
Signing: a clean, documented process that is not rushed.

Prenuptial & Postnuptial Agreement FAQs

Is a “prenup” the same thing as a “premarital agreement” in Texas?

Yes. “Prenup” is the common term. Texas statutes refer to a “premarital agreement,” meaning an agreement made in contemplation of marriage that becomes effective on marriage. (Tex. Fam. Code § 4.001(1), § 4.004.)

What is a postnuptial agreement in Texas?

People sometimes use “postnup” to describe marital property agreements signed after marriage. Texas law allows spouses to partition/exchange community property and to make agreements about income from separate property, among other options—subject to writing/signature requirements and enforceability standards. (See generally Tex. Fam. Code §§ 4.101–4.105, 4.102–4.104.)

Are prenups enforceable in Texas?

They can be. Texas provides specific defenses and standards—most commonly issues about voluntariness, unconscionability, and whether disclosure/waiver/knowledge requirements were met. (Tex. Fam. Code § 4.006.) A careful process on the front end reduces enforceability risk later.

Can a prenup address spousal support or spousal maintenance?

Texas law allows premarital agreements to address “the modification or elimination of spousal support.” (Tex. Fam. Code § 4.003(a)(4).) Whether a particular provision will be enforced can depend on the facts, the language used, and other applicable law.

If a prenup says the “breadwinner” won’t pay the other spouse’s attorney’s fees, can a court still order fees?

Sometimes, yes—especially while a divorce is pending. Texas courts can have statutory authority to award interim attorney’s fees as part of temporary orders to ensure both sides can be represented (commonly addressed under Tex. Fam. Code § 6.502(a)(4)), and fee issues can also arise in the final decree under other Family Code provisions. The enforceability of any “fee waiver” language is fact-specific, so it is wise to discuss this during drafting if a large income disparity exists.

Do both parties need separate lawyers for a prenup or postnup?

Independent counsel is strongly recommended. It helps each party understand what they are agreeing to and reduces future claims that someone did not sign voluntarily or did not understand the effect of the agreement—issues that often drive litigation later.

We’re not “high net worth.” Is a prenup still worth considering?

It can be. Many agreements focus on debt allocation, future earnings, expected inheritances, a business being built during the marriage, or clear rules for property and reimbursements. The question is whether a written framework meaningfully reduces risk and future conflict in your situation.
