More couples in New Braunfels are talking about prenuptial agreements before they marry. Some own a business or a home near the river. Some are marrying later in life, after building retirement savings or raising children from a first marriage. Others simply want to start their marriage with clear expectations about money. A Texas prenup, which the law calls a premarital agreement, lets you make those decisions together, in advance, instead of leaving them to a Comal County judge if the marriage ends. This page explains what a prenup can do and how to make one that holds up.
Why Texas Couples Consider a Prenup
Texas is a community property state. Unless a couple agrees otherwise, most property acquired during the marriage is presumed to belong to the community, and on divorce it is divided in a “just and right” manner. Income from separate property, such as rent from a house one spouse owned before marriage or dividends on inherited stock, is community property by default. Many people are surprised to learn that. Our pages on community property and separate property explain the default rules.
A premarital agreement lets you change many of those defaults. Common goals include:
- Keeping a business, practice or ranch as one spouse’s separate property, including its growth
- Making income from separate property remain separate
- Protecting an inheritance or family land for children from a prior relationship
- Defining how a home bought during the marriage will be owned and divided
- Addressing responsibility for debts, such as student loans
- Setting expectations about spousal support
- Coordinating with estate plans, trusts and life insurance
What a Texas Prenup Can Cover
Chapter 4 of the Texas Family Code allows engaged couples to agree on a wide range of property issues, including:
- Each spouse’s rights in property, whenever and wherever acquired
- The right to buy, sell, use, manage and control property
- How property is handled on separation, divorce, death or other events
- Modification or elimination of spousal support
- Making a will or trust to carry out the agreement
- Ownership of life insurance death benefits
- Which state’s law governs the agreement
- Any other matter, including personal rights, that does not violate public policy or criminal law
What a Prenup Cannot Do
There are firm limits. A premarital agreement cannot adversely affect a child’s right to support. Parents also cannot use a prenup to bind a court on custody or possession, because those issues are decided based on the child’s best interest when they arise. Terms that encourage divorce or violate public policy may also be unenforceable.
Making a Prenup Enforceable
Texas premarital agreements must be in writing and signed by both parties. They take effect when the couple marries. Under Texas Family Code § 4.006, a spouse who wants to avoid the agreement must prove one of two things:
- The agreement was not signed voluntarily, or
- The agreement was unconscionable when signed, and before signing, that spouse: - Was not given a fair and reasonable disclosure of the other party’s property or financial obligations, and - Did not voluntarily and expressly waive, in writing, any right to disclosure beyond what was provided, and - Did not have, or reasonably could not have had, adequate knowledge of the other party’s property or financial obligations.
Whether an agreement is unconscionable is decided by the judge, not a jury. Because these standards protect agreements that were fairly made, the best way to strengthen a prenup is to build a clear record of fairness.
Best Practices That Strengthen a Prenup
- Start early. Begin months before the wedding, not days. Venues, invitations and travel plans put pressure on people.
- Disclose fully. Attach schedules listing assets, debts and income, with values and supporting statements.
- Use separate lawyers. Each person should have independent counsel who reviews the agreement and explains it.
- Use plain language. Both people should be able to read and understand the terms.
- Sign in a calm setting. Avoid signing at the rehearsal dinner or on the wedding day.
- Keep copies. Store signed originals and disclosure schedules safely, and tell your estate planning attorney about the agreement.
A Practical Timeline for New Braunfels Couples
Every couple’s timeline is different, but a comfortable plan often looks like this:
| Before the wedding | Step |
|---|---|
| 4–6 months | Talk with your partner about the idea and your goals |
| 3–4 months | Each person meets with their own lawyer; begin gathering financial records |
| 2–3 months | First draft circulated with disclosure schedules |
| 1–2 months | Negotiate changes and finalize |
| At least several weeks | Sign, with time to spare before the wedding |
Starting the conversation is often the hardest part. Our guide to talking about a prenup offers suggestions for bringing it up kindly and productively.
Special Situations
Business Owners
For a business owner in New Braunfels, a prenup can define how the business, its growth and the owner’s salary will be treated. Without an agreement, a spouse’s time and effort during marriage can give the community a claim even if the business started as separate property. Our page on business in divorce explains why this matters.
Second Marriages and Blended Families
People marrying again often want to protect children from an earlier relationship. A prenup can work alongside a will, trust and beneficiary designations to make sure family property passes as intended.
Military Families
For service members near Joint Base San Antonio, a prenup can address military retirement and frequent moves. Federal law sets rules about direct payment of retirement shares, and an agreement should be drafted with those rules in mind.
Couples Moving to Texas
Couples who sign a prenup elsewhere and then move to Comal County should have the agreement reviewed. Choice-of-law clauses and Texas community property rules can interact in unexpected ways.
A Prenup and Your Comal County Divorce
If a marriage with a prenup ends in divorce, the agreement usually guides the property division. A spouse may still challenge enforceability under § 4.006, and the court will look at how the agreement was made. A carefully prepared prenup makes this part of a divorce much simpler, and often much less expensive.

Frequently Asked Questions
Does a Texas prenup have to be notarized?
Texas law requires a premarital agreement to be in writing and signed by both parties. Notarization is not strictly required for validity, but many lawyers recommend it, along with separate counsel and written disclosures, because those steps make the agreement easier to prove and harder to challenge.
Can a prenup decide custody or child support?
No. A premarital agreement cannot adversely affect a child’s right to support. Custody and possession are decided based on the child’s best interest when the issue arises. Parents can make plans, but a court is not bound by a prenup on those issues.
Can we sign a prenup the week before the wedding?
It is legally possible, but signing very close to the wedding invites a later claim that the agreement was signed under pressure. Starting at least a few months ahead gives each person time to review disclosures and talk with their own lawyer.
What if we are already married?
Then the agreement is a marital agreement, often called a postnuptial agreement. Texas law allows spouses to partition property and make other arrangements during marriage. See our page on postnuptial agreements.
Can a prenup be changed after the wedding?
Yes. After marriage, a premarital agreement can be amended or revoked only by a written agreement signed by both spouses. No additional consideration is needed for the amendment.
