Not every Houston couple living together wants to be married. Some plan to marry someday but are not ready yet. Some have been married before and have no interest in doing it again. Some are committed long-term partners who simply do not want the legal entanglement of marriage. For all of these couples, Texas presents a quiet risk: an informal marriage can form without anyone meaning to create one, and the legal consequences are the same as a ceremonial marriage.
A cohabitation agreement is the cleanest tool for couples who want to share their lives without sharing a marriage. Here is how it works, what it should cover, and why it is one of the most underused legal documents in Texas family law. For the full picture of how informal marriage actually forms in Texas, see our complete guide to common law marriage.
The Risk Most Couples Don’t See Coming
Texas Family Code Section 2.401 allows a common law marriage to form whenever three things line up: an agreement to be presently married, cohabitation in Texas as spouses, and holding yourselves out to others as married. None of those elements requires paperwork. None of them requires anyone to call a lawyer. The agreement element can be inferred from conduct, and the holding-out element can develop accidentally through tax returns, insurance forms, hospital paperwork, or even casual social introductions.
That means couples in Houston, the Heights, Spring, Cypress, Richmond, or anywhere else in Texas can drift into a common law marriage simply by living their lives. If the relationship later ends, one partner can claim the marriage existed and seek property division, spousal maintenance, and other rights. Even if the claim ultimately fails, defending against it costs time and money.
What a Cohabitation Agreement Does
A cohabitation agreement is a written contract between unmarried partners that spells out the financial and practical terms of their relationship. For couples who do not want to be married, the most important thing it does is directly address the agreement element of an informal marriage. A clear, signed statement that the parties do not intend to be married is strong evidence on the question Texas courts ask first.
A well-drafted cohabitation agreement typically covers:
- Marital intent. An explicit, signed declaration that the parties are not married, do not intend to be married, and are not entering into an informal marriage under Texas law.
- Property ownership. How property purchased before and during the relationship is owned. Whose name is on what. How jointly purchased property is treated if the relationship ends.
- Income and expenses. How household expenses are split, whether either party is contributing to the other’s separate property, and how shared accounts (if any) work.
- Debts. Each party’s responsibility for their own debts. Whether either party is co-signing or guaranteeing the other’s obligations.
- Separation procedures. What happens to shared property and shared debts if the parties separate. How disputes are resolved.
- Inheritance and estate planning. Confirmation that neither party expects to inherit from the other absent a will. Coordination with each party’s existing estate plan.
- Children. Provisions for any children born or adopted during the relationship, while recognizing that parental rights and child support are determined by Texas law and cannot be contracted away.
Who Should Consider One
Cohabitation agreements make sense for a wide range of Houston-area couples, including:
- Couples who plan to live together long-term without marrying.
- Couples where one or both partners have significant separate assets, business interests, or retirement accounts they want to protect.
- Couples who have been previously married and are deliberately choosing not to marry again.
- Couples who plan to marry someday but want clarity about their financial arrangement during the interim.
- Couples where one partner is moving into a home owned by the other.
- Couples who are blending finances, sharing big purchases, or running businesses together but do not want the marital framework.
Why Texas Courts Take Them Seriously
Texas generally enforces written contracts between adults, and cohabitation agreements are no exception when they are properly drafted, voluntarily signed, and supported by full disclosure. A clear, signed statement that the parties are not married does powerful work in any later dispute. It is direct, contemporaneous evidence on the agreement element, and it is much harder to disprove than testimony reconstructed years after the fact.
Cohabitation agreements are not bulletproof. A party can still try to argue that despite the agreement, the parties’ subsequent conduct created a marriage anyway. But starting from a written, signed denial of marital intent puts the other side in a much weaker position than starting from silence.
How to Get One Done
A cohabitation agreement is a contract. It needs to be drafted clearly, signed by both parties, and supported by an honest exchange of financial information. Both partners should ideally be represented by their own attorneys, or at minimum, both should have a chance to review the agreement with independent counsel before signing. Agreements signed under pressure, without disclosure, or without independent advice can be challenged later.
For Houston couples, the cost of a properly drafted cohabitation agreement is modest compared to the cost of fighting an informal marriage claim later. Whether your relationship is just starting or you have been together for years and want to clarify where you stand, talking to a Houston family law attorney about a cohabitation agreement is worth the time.
