Buying a House Together Without Being Married in Texas: What Dallas Couples Need to Know

What happens legally when an unmarried couple buys a house in Texas?

In Texas, community property laws apply only to legally married spouses. If you and your partner buy a home without being married, you have no community property protections, and the default ownership structure is tenancy in common. That means either of you can legally force a sale without the other's consent. You need to choose your title structure carefully (tenancy in common or joint tenancy with right of survivorship) and put a written co-ownership agreement in place to protect both of your interests.

You found the house. You've got the down payment. You're ready to buy together. The only thing missing is a ring, and right now, that's not the priority.

More Dallas couples are buying homes together before marriage than at any point in recent memory. Young professionals in Uptown and the M Streets, move-up buyers heading north to Frisco or Plano, long-term partners who have decided that homeownership makes financial sense before a wedding date does. It's a smart move in a lot of ways, but it comes with legal exposure that most buyers don't realize until something goes wrong.

Here's what you need to know before you sign anything.

Texas Community Property Does Not Cover You

This is the first thing to understand, and it matters.

Texas is a community property state, which means married couples share most assets acquired during marriage. But that protection applies only to legally married spouses. If you're unmarried when you buy the home, community property law doesn't enter the picture at all, even if you later get married.

What you have instead is a private co-ownership arrangement. And the default terms of that arrangement under Texas law may not be what you'd expect.

Your Two Title Options

When two unmarried people buy a home in Texas, the deed determines who owns what and what happens if one partner dies, moves out, or wants to sell. There are two primary options.

Tenancy in Common

This is the Texas default. If your deed doesn't specify otherwise, you own the home as tenants in common.

Under tenancy in common:

• Each partner holds a defined ownership percentage (which can be unequal, like 70/30 if one person contributed more to the down payment)
• If one partner dies, their share passes through their estate, not automatically to the survivor
• Either partner can sell their individual share or leave it in a will to whoever they choose

The survivorship risk is real. If you and your partner own as tenants in common and your partner dies without a will, their share goes to their legal heirs. That could mean their parents, siblings, or whoever inherits their estate becomes your new co-owner on the property.

Joint Tenancy with Right of Survivorship

This is the structure most unmarried couples actually want when they think it through.

Under joint tenancy with right of survivorship:

• Both partners hold equal shares (you can't do 70/30; this structure requires equal ownership)
• If one partner dies, the other automatically inherits the full property, bypassing probate
• The deed must explicitly state the right of survivorship

This language matters more than most buyers realize. Texas law does not assume survivorship rights just because two people are on a deed. The deed has to say, specifically: "as joint tenants with right of survivorship and not as tenants in common." Your title company and real estate attorney need to include that exact phrase.

The Partition Problem Nobody Talks About

Here's the legal reality that catches most unmarried co-buyers off guard.

Under the Texas Property Code, either co-owner in a tenancy in common has the right to file for partition. That means they can go to court and force the sale of the property, even if the other partner refuses.

As Dallas family law attorney Lisa McKnight has explained, buying property with an unmarried partner is legally similar to a business partnership: each partner has "the unequivocal right to partition, which means to sell if they want to."

The scenario plays out like this. The relationship ends. One partner wants to keep the house and refinance, but can't qualify alone. The other can legally force a sale through the courts. Neither person wins. The house gets sold, proceeds get split, and both partners lose the equity they spent years building.

A properly drafted co-ownership agreement with a buy-out provision can prevent this from ever becoming a court case.

One Name or Two Names on the Mortgage?

The mortgage question is separate from the deed question, and buyers confuse these constantly.

Both on the mortgage: Both partners are equally responsible for the debt. Lenders typically use the lower of the two credit scores when qualifying you for the loan. If one partner has a significantly weaker credit profile, this can affect your rate or your approval. Co-Borrower vs. Co-Signer on a Texas Mortgage: What Dallas Buyers Need to Know covers the trade-offs in detail.

One name on the mortgage: Only the named borrower is legally responsible for the loan. This can improve your rate if one partner has stronger credit. But the non-borrowing partner needs to be protected on the deed, and both partners need a clear written agreement on how payments, expenses, and equity are tracked.

The key distinction: whoever is on the deed holds legal ownership. The mortgage determines debt liability. These can be structured differently, and sometimes that's the right call. Just make sure the equity and payment agreement is in writing before you close.

Why You Need a Co-Ownership Agreement

A co-ownership agreement is a written contract that defines how the property will be managed, how costs will be split, and what happens if the relationship changes. Under Texas Business and Commerce Code Section 26.01, agreements about real property must be in writing and signed by both parties to be enforceable.

Without one, any dispute over the property defaults to Texas law. That usually means a partition lawsuit, significant legal fees, and a forced sale neither person wanted.

A solid co-ownership agreement should cover:

• Down payment contributions and how unequal contributions are tracked
• Monthly payment split for mortgage, taxes, insurance, and any HOA dues
• Maintenance and capital improvement costs, and whether they adjust each partner's equity stake
• What happens on a breakup: buy-out timeline, how to calculate the buy-out price, and whether one partner has right of first refusal
• What happens if one partner can't pay: a grace period, a refinance clause, or a sale trigger
• Dispute resolution: mediation before litigation

This doesn't need to be a long document. A few pages drafted by a Texas real estate attorney gives both of you the protection you'd otherwise spend significantly more on in court.

One more thing to sort out while you're thinking through ownership structure: what happens to the property if one partner dies before you sort out the deed type?

Frequently Asked Questions

Can an unmarried couple buy a house together in Texas?

Yes. Unmarried co-buyers in Texas can purchase a home together, appear on the deed, and structure the mortgage with one or both names on the loan. You don't have community property protection, so your legal ownership structure and a written co-ownership agreement become the tools that protect both of you instead.

What is the difference between tenancy in common and joint tenancy with right of survivorship in Texas?

Tenancy in common is the Texas default for unmarried co-buyers. Each partner holds a percentage share that passes through their estate when they die. Joint tenancy with right of survivorship gives the surviving partner automatic full ownership when the other partner dies, but requires explicit language in the deed and equal ownership shares. Most unmarried couples who want survivorship protection should choose joint tenancy, and the deed must say so specifically.

Can one partner force the sale of a jointly owned home in Texas?

Yes. Under Texas Property Code Chapter 23, any co-owner can file a partition action, which forces a court-ordered sale of the property and a split of the proceeds. A co-ownership agreement with a buy-out clause and a defined dispute resolution process is the most practical way to prevent this outcome when the relationship ends.

Does it matter whose name is on the mortgage versus the deed?

Yes, significantly. The deed determines legal ownership. The mortgage determines debt responsibility. Both partners can appear on the deed while only one is on the mortgage, which is a common structure when there's a meaningful credit score difference between partners. A clear written agreement on how payments and equity are handled becomes essential in that arrangement.

Do I need a real estate attorney when buying a home with an unmarried partner in Texas?

You don't legally require an attorney to purchase real estate in Texas, but buying as unmarried co-owners makes one strongly advisable. The deed language, the ownership structure, and the co-ownership agreement each require legal precision that a real estate attorney specializing in property or family law can provide. In Dallas, there are firms that handle this type of transaction alongside a standard real estate closing.
