In 2026, a prenup typically costs between $600 and $10,000 or more per couple, depending on how the agreement is created.
A DIY online template runs $600, software-drafted agreements with attorney review run $2,000 and up, and a traditional attorney billing hourly typically costs $2,500 to $10,000 or more.
At Prenups.com, a prenup is a flat $3,500, or $5,000 to include negotiations with your partner’s attorney. No hourly billing.
| Approach | Typical cost (per couple) | When a lawyer gets involved | Best for |
|---|---|---|---|
| DIY online template | $600 | Never | Simple finances, no major assets, willing to risk enforceability |
| Software-drafted + attorney review | $2,000 and up | After the document is generated | Couples who have already agreed on every term and want it documented |
| Attorney-drafted, flat fee (Prenups.com) | $3,500 flat, plus independent review for your partner | From the first conversation, before anything is drafted | Couples who want an attorney to design the agreement around their goals, at a predictable price |
| Traditional hourly attorney | $2,500 to $10,000+ | From the first conversation | Couples with an existing attorney relationship, open-ended budget |
A prenup drafted by a licensed attorney who knows Texas’s enforceability rules is a fundamentally different product from an online template. A $3,500 agreement that holds up in court is worth more than a $600 template that does not.
Key Takeaways
- In 2026, a prenup in Texas typically costs between $600 and $10,000 or more per couple, depending on how it is created. Prenups.com charges a flat $3,500, with no hourly billing.
- The $3,500 flat fee is about 11 percent of the $31,000 average Texas wedding cost reported by The Knot 2026 Real Weddings Study.
- Texas follows community property rules. By default, income earned during the marriage is community property, and so is income generated by separate property, such as dividends and interest. A prenup can change both defaults.
- Under Tex. Fam. Code § 4.006, a challenger can defeat a prenup by proving it was not signed voluntarily, or by proving it was unconscionable when signed and that, before signing, the challenger did not receive fair and reasonable disclosure, did not expressly waive disclosure in writing, and did not have and could not reasonably have had adequate knowledge of the other person’s finances. The statute makes those grounds exclusive.
- A Texas prenup must be in writing and signed by both people. Witnesses and independent counsel are not required.
What a Prenup Costs in Texas
A prenup in Texas typically runs between $2,500 and $10,000 when an attorney bills hourly. The low end usually means a simple agreement between two people with uncomplicated finances, and at the very bottom of that range you are often paying for a near-form document from an attorney who does not specialize in these agreements. Add a business, significant premarital assets, mineral interests, children from a prior relationship, or heavy negotiation, and the number climbs toward the top of the range.
Put the flat fee in context. The Knot 2026 Real Weddings Study, which surveyed couples married in 2025, puts the average Texas wedding at $31,000. A $3,500 agreement is about 11 percent of that figure, and it shapes how a divorce would work for as long as the marriage lasts.

What Community Property Does and Doesn’t Protect in Texas
Texas is a community property state. By default, income either spouse earns during the marriage is community property, whether or not it ever touches a joint account. That default is predictable and clean, and it applies without anyone having to prove anything. What it does not do is keep separate property separate on its own.
Texas adds a default that surprises most people: income from separate property is community property too. A brokerage account one spouse owned before the wedding stays separate, but by default the dividends and interest it earns during the marriage are community. Leave them in the account, add post-wedding paychecks, and the account becomes a mix of separate and community money. In a divorce, the spouse claiming separate property has to trace it by clear and convincing evidence, and whatever cannot be traced is presumed community.
A business works differently. Paying down a premarital business loan or mortgage with community income does not change who owns the asset, but it can give the community a reimbursement claim against it. Either way, the routines people adopt to keep things separate are often what create the community claim. A prenup is the instrument that settles, in writing and in advance, how income from separate property is classified and how contributions are treated.
The Only Grounds for Challenging a Texas Prenup
Texas follows the Uniform Premarital Agreement Act, Tex. Fam. Code ch. 4, and § 4.006 governs enforcement. A challenger has two routes. The first is voluntariness: an agreement that was not signed voluntarily is not enforced. The second is an unfairness challenge, and it is demanding. The challenger has to prove the agreement was unconscionable when signed, and also that before signing they did not receive fair and reasonable disclosure of the other person’s property and obligations, did not expressly waive that disclosure in writing, and did not have and could not reasonably have had adequate knowledge of it. A judge, not a jury, decides unconscionability.
Section 4.006 also states that these remedies and defenses are exclusive, including any common-law ones. That is what makes Texas strongly pro-enforcement: a challenger cannot reach for a broader fairness theory outside the statute. Separately, no prenup can adversely affect a child’s right to support. The statute also rewards a specific kind of preparation. Unconscionability is hard to control. Disclosure is not. An agreement with complete, documented disclosure leaves a challenger nothing to prove on that half of the unfairness route, and a signing with time to decide leaves little to argue on voluntariness.
Thinking about a prenup?
Talk to an attorney before you decide. A 30-minute consultation is $150, credited toward your agreement if you move forward.

No agreement can promise how a particular court will rule, and anyone who says otherwise is overselling. A prenup that is enforceable in court in Texas is one where disclosure, voluntary signing, and fair terms were built in from the first draft.
What Moves the Price
Complexity does most of the work. Two people early in their careers with straightforward assets need a simpler agreement than a couple bringing a business, real estate, retirement accounts, or equity compensation into the marriage. Couples are also marrying later. The U.S. Census Bureau reports a 2025 median age at first marriage of 30.8 for men and 28.4 for women, so many people arrive with years of financial history already built.
Negotiation is the second lever, since an aligned couple moves quickly and a couple working out support or a business spends more time. Independent review for your partner is the third. Texas does not require it, but it strengthens the agreement by showing both people understood what they signed.
A Known Price Before the First Draft
Many Texas family law attorneys bill prenups by the hour. That is hard to budget for, because the final bill depends on how many revisions you want and how long a negotiation runs, none of which you can know on day one. It also creates a quiet temptation to trim the disclosure work when the meter feels high, which is the half of the test an agreement can control.
Prenups.com charges $3,500 for a Texas prenup, with no hourly billing, so the price is known before the work begins. An attorney is also in the conversation from the first call, before anything is drafted, which is where the disclosure record gets built.
Starting the Process
The process begins with a consultation to understand your situation and goals, followed by financial disclosure from both people, drafting, a round of review and revisions, and signing. A Texas prenup has to be in writing and signed by both people, and no witnesses are required, so signing is straightforward once the agreement is ready.

Frequently Asked Questions
How much does a prenup cost in Texas?
In 2026, a prenup typically costs between $600 and $10,000 or more per couple, depending on how it is created. A traditional attorney billing hourly usually runs $2,500 to $10,000 or more. At Prenups.com, a Texas prenup is a flat $3,500, with no hourly billing.
Are prenups enforceable in Texas?
Yes, and Texas is strongly pro-enforcement. Under Tex. Fam. Code § 4.006, a challenger has to prove the agreement was not signed voluntarily, or that it was unconscionable when signed and that they did not receive fair and reasonable disclosure, did not expressly waive disclosure in writing, and did not have and could not reasonably have had adequate knowledge of the other person’s finances. Those grounds are exclusive, and the burden is on the challenger.
Is income from my separate property separate in Texas?
Not by default. Cash dividends, interest, rents, and most other income generated by separate property during the marriage are community property unless a prenup provides otherwise. Mineral royalties are a notable exception. Many Texas agreements are drafted specifically to keep that income separate.
Does a Texas prenup need witnesses or a lawyer for each partner?
Texas requires only that the agreement be in writing and signed by both people. Witnesses and independent counsel are not required. Independent review for your partner is still worth considering because it helps show that both people understood the terms. The $3,500 flat fee is for the agreement itself, and independent review for your partner is separate.
Is a $600 online template enough in Texas?
Rarely. A template does not build the disclosure record that is half of Texas’s unfairness test, and it comes with no attorney to design the agreement around your finances. A flat $3,500 agreement that holds up in court is worth more than a $600 template that does not.
Can we sign a marital agreement in Texas after the wedding?
Yes, but it is a different instrument. Texas spouses use partition and exchange agreements or conversion agreements, governed by separate subchapters of the Family Code with their own requirements, not prenups signed after the wedding.
