Unmarried couples’ property rights in Texas are limited by default: each partner owns only what is titled in their name or what they can prove they paid for. There is no automatic sharing of assets acquired during the relationship, no matter how long you have lived together. Two things can change that picture — qualifying as an informal (common law) marriage, or signing a written agreement that spells out what you both own. Without one of those, Texas law treats you and your partner as separate individuals for property purposes.
The Default Rule: Title Controls
When two people live together without marrying, Texas law looks at legal title to decide who owns what. A house in one partner’s name belongs to that partner. A car loan in one partner’s name means that partner owns the car. Bank accounts, investments, and furniture bought on one person’s credit card all belong to the person whose name is on the account or receipt, regardless of how long the couple has been together or how much the other partner contributed to household expenses.
The result can be harsh. A partner who spent years paying half the mortgage on a home titled in the other’s name has no ownership interest in that home, unless they can point to a written agreement or prove a common law marriage. The same logic covers retirement savings, business assets, and anything else acquired during the relationship. Documentation matters enormously: keeping records of financial contributions, purchase receipts, and any written understandings about shared assets is the single most important thing an unmarried partner can do.
The Commingling Trap
Mixing your money with your partner’s creates a tracking problem that can cost you later. When separate funds go into a shared bank account and both partners deposit and withdraw from it, proving which dollars belong to whom becomes difficult. This is called commingling. If you deposit $30,000 of inheritance money into a joint checking account that both of you use for groceries, rent, and vacations, that inheritance may effectively disappear into the shared spending.
The legal remedy is tracing — following the money trail back to its source to prove which funds were yours. The party claiming ownership carries the burden of proving it by clear and convincing evidence, a higher bar than most civil cases require. In practice, that means detailed bank statements, deposit records, and often forensic accounting. Partners who want to protect separate assets should keep them in separate accounts and document any transfers carefully.
Common Law Marriage Changes Everything
Texas is one of a handful of states that still recognizes common law marriage, called “informal marriage” in the Family Code. If you qualify, your relationship carries the same legal weight as a ceremonial marriage, including community property rules. Property acquired by either partner during the informal marriage is presumed to belong to both of you equally.1State of Texas. Texas Family Code Section 3.002 – Community Property
To establish an informal marriage, you must meet all three requirements at the same time under Texas Family Code Section 2.401:2State of Texas. Texas Family Code Section 2.401 – Proof of Informal Marriage
- An agreement to be married. Both of you must have a present, mutual intent to be married now — not a plan to marry someday. The agreement can be spoken or implied from your behavior, but it must reflect an immediate commitment.
- Living together as spouses in Texas. You must share a household in the state. There is no minimum time requirement; even a brief period of cohabitation can count if the other elements are met.
- Holding out as married. You must represent to other people that you are married. That means introducing each other as spouses, wearing wedding rings, filing joint tax returns, signing documents as a married couple, or similar public declarations. A relationship kept private or described as “just dating” will not satisfy this element.
Courts evaluate these factors case by case, and satisfying all three simultaneously can be harder to prove than people expect. The partner claiming an informal marriage exists carries the burden of proof, and testimony from friends, family, landlords, and employers often becomes critical evidence.
The Two-Year Clock After Separation
If you believe you were in a common law marriage, do not wait too long to assert it. Texas law creates a rebuttable presumption that no agreement to marry existed if you do not file a legal proceeding within two years of the date you separated and stopped living together.2State of Texas. Texas Family Code Section 2.401 – Proof of Informal Marriage “Rebuttable” means you can still try to prove the marriage after two years, but the legal deck is stacked against you. Waiting past that mark makes an already difficult case significantly harder to win.
If You Move Out of Texas
A valid Texas common law marriage does not evaporate when you cross state lines. Most states recognize a marriage validly created in another state, even if that state does not allow common law marriages to be formed within its own borders. The Social Security Administration also recognizes common law marriages from states that permit them, so a surviving common law spouse may qualify for survivor benefits with proper documentation.3Social Security Administration. Code of Federal Regulations Section 404.726 – Evidence of Common-Law Marriage
Recovering Contributions Without a Marriage
Even when no common law marriage exists, a non-titled partner is not always out of luck. Texas courts can recognize equitable ownership claims based on financial contributions and implied agreements, though these cases are fact-intensive and expensive to litigate.
The most common approach is tracing. If you used your own separate funds, such as an inheritance or pre-relationship savings, as a down payment on property titled in your partner’s name, you can try to follow that money trail to establish your interest. The evidentiary standard is the challenge: clear and convincing evidence means more than your word against theirs. Bank records, wire transfer confirmations, and contemporaneous communications are the kinds of documentation courts want to see.
Courts may also look at the couple’s conduct for evidence of an implied agreement to share ownership. If both partners paid the mortgage, maintained the property, and made decisions about it together over many years, a court might infer that the titled partner intended to share ownership. These arguments are far from guaranteed and depend heavily on the facts.
Cohabitation Agreements
A cohabitation agreement is the closest thing unmarried partners have to a prenuptial agreement. It is a written contract that spells out who owns what, how debts are shared, and what happens to property if you split up or one of you dies. When properly drafted and signed by both parties, these agreements are enforceable in Texas under general contract principles.
A well-drafted cohabitation agreement typically covers:
- Real estate. Who owns the home, how mortgage payments are split, and what happens to equity if one partner moves out.
- Bank accounts and investments. Which accounts are shared and which remain separate, and how joint balances get divided.
- Debts. Who is responsible for the mortgage, car loans, and credit card balances incurred during the relationship.
- Personal property. Ownership of furniture, vehicles, and other belongings, especially items purchased together.
- Digital assets. Cryptocurrency, NFTs, and income-generating online businesses or social media accounts can have real value and are easy to overlook. Specifying ownership and valuation methods upfront avoids messy disputes later.
A cohabitation agreement also serves a defensive purpose. By explicitly stating that you do not intend to be married, it can help prevent an accidental common law marriage claim. If your relationship produces enough outward signals of marriage, one of you could later argue that an informal marriage existed; a clear written statement of intent undercuts that argument. Legal fees for drafting typically run a few hundred to several hundred dollars, a fraction of what contested property litigation costs.
When You Cannot Agree: Partition Suits
If an unmarried couple separates without a cohabitation agreement or a recognized common law marriage, and they cannot agree on how to divide jointly owned assets, either partner can file a partition suit. Texas Property Code Section 23.001 gives any joint owner of real or personal property the right to ask a court to divide it.4State of Texas. Texas Property Code Section 23.001 – Partition
In a partition action, the court can either physically divide the property (possible with land, rarely practical with a house) or order it sold and the proceeds split. The court determines each partner’s share based on actual contributions and any evidence of agreements between them, not the community property rules that apply to married couples. This is where documentation of payments, deposits, and written understandings pays off. Partition suits are real litigation with real costs, and a negotiated settlement almost always costs less than going to court.
What Happens If Your Partner Dies
This is where the gap between married and unmarried couples is starkest. If your partner dies without a will and you are not married, formally or informally, you inherit nothing under Texas law. The estate passes to the deceased partner’s children, parents, siblings, or more distant relatives, in that order, with no recognition of an unmarried partner.5State of Texas. Texas Estates Code Section 201.001 – Estate of an Intestate Not Leaving a Spouse
That means the home you shared, bank accounts in your partner’s name, and any other assets titled to them could pass entirely to family members you may barely know. Even property you helped pay for becomes part of their estate, and you would have to file a separate legal claim to recover your contributions.
Healthcare Decisions
The problem extends beyond property. If your partner becomes incapacitated and has not signed a medical power of attorney, Texas law dictates who makes healthcare decisions, and unmarried partners are not on the list. The statutory priority runs from spouse to adult children to parents to nearest living relative.6Texas Public Law. Texas Health and Safety Code Section 166.039 – Procedure When Person Has Not Executed or Does Not Have Effective Directive A partner of twenty years has no more legal authority than a stranger unless formally designated as a healthcare agent.
Essential Estate Planning Documents
Unmarried couples who want to protect each other need to take deliberate steps that married couples can often take for granted:
- A will that specifically names the other partner as a beneficiary for any assets you want to pass to them.
- A medical power of attorney giving your partner authority to make healthcare decisions if you cannot.
- Beneficiary designations on life insurance policies, retirement accounts, and payable-on-death bank accounts naming your partner directly. These override whatever your will says, so keeping them current is critical.
- A HIPAA authorization. Without it, hospitals and doctors may refuse to share medical information with your partner.
One quirk worth knowing: under federal ERISA rules, if you later marry someone else, that marriage automatically overrides a prior beneficiary designation on a 401(k) or employer-sponsored plan. Your new spouse becomes the default beneficiary, and they must consent in writing before anyone else can be named.
Federal Tax Consequences
Unmarried partners must file federal tax returns as individuals. You cannot file a joint return regardless of how long you have lived together or how intertwined your finances are. Each partner files as single, or as head of household if they have a qualifying dependent living with them. If both partners live with the same child, only one can claim head of household for that child.
Property transfers between unmarried partners can also trigger gift tax rules. Married spouses can transfer unlimited property between themselves tax-free; unmarried partners cannot. In 2026, each person can give up to $19,000 per recipient per year without filing a gift tax return.7Internal Revenue Service. Frequently Asked Questions on Gift Taxes Transfers above that threshold require filing Form 709, though no tax is actually owed until you exceed the $15,000,000 lifetime exemption.8Internal Revenue Service. What’s New – Estate and Gift Tax
Where this matters in practice: if one partner pays the entire mortgage on a home both partners live in, or adds the other to a property title without receiving payment, the IRS could treat the excess value as a taxable gift. Most couples will not hit the lifetime exemption, but failing to file the required return is itself a compliance problem worth avoiding.
Property Division If a Common Law Marriage Is Proven
If a court determines that an informal marriage existed, the couple goes through the same divorce process as any formally married couple. The court divides the community estate in a manner it considers “just and right,” taking into account each spouse’s circumstances and the needs of any children.9State of Texas. Texas Family Code Section 7.001 “Just and right” does not necessarily mean a 50/50 split. Courts can award a larger share to one spouse based on factors like earning capacity, fault in the breakup, and who has primary custody of children.
Property each partner owned before the informal marriage began, along with gifts and inheritances received during it, remains separate. But proving which assets are separate and which are community gets complicated fast, especially when the couple never had a clear start date. This ambiguity is one reason common law marriage disputes tend to be more expensive to litigate than conventional divorces: the fight over whether the marriage existed at all often comes before the fight over how to divide property.
