New Texas Law Requires a Signed Agreement Before an Agent Can Show You a Home — Here's What San Antonio Buyers Need to Know

If you are planning to buy a home in San Antonio this year — whether you are eyeing a starter home in Converse, a new build in Cibolo, a classic ranch-style house in Helotes, or a condo near the Pearl — there is a new rule you need to understand before you set foot inside a single property.

Effective January 1, 2026, Texas law under TRELA Section 1101.563 requires that any licensed real estate agent working with a prospective buyer of residential property must have a written agreement in place before showing any home or presenting any offer on your behalf. This is not a suggestion or a best practice — it is the law.

For most buyers in the San Antonio metro area, this will be the first time they have encountered this requirement, and it is worth taking a few minutes to understand what it actually means for you.

There are two types of written agreements that satisfy the new law. The first is a buyer representation agreement, in which you formally hire an agent and a brokerage to represent your interests throughout your home search. The second is a shorter, more limited option: a non-exclusive, non-representation showing-only agreement. This type of agreement covers a single agent showing you properties and lasts no more than 14 days. It does not create a full representation relationship, but it does meet the legal requirement to get you through the door.

Both types of agreements must clearly spell out what services the agent will provide and what the broker's compensation will be. They must also include a conspicuous statement — meaning it has to stand out, not be buried in fine print — that broker compensation is not set by law and is fully negotiable. That last point matters. You have the right to discuss and negotiate what an agent earns, and Texas law now requires that agents make that crystal clear to you in writing before anything else happens.

If you are wondering why this change came about, it is part of a broader national shift toward greater transparency in real estate transactions. The written agreement requirement puts the terms of your relationship with an agent on the table from the very first interaction rather than leaving them vague until you are already deep into the process.

For buyers in high-activity San Antonio markets — communities like Boerne, Schertz, New Braunfels, and Stone Oak, or ZIP codes like 78258, 78249, and 78209 — this change should not slow you down once you understand what to expect. Agents are prepared for this. Your first conversation with an agent will now include a brief explanation of the agreement, a review of services, and a discussion of compensation before you visit any property.

If you are relocating to San Antonio from out of state, this is important to know before you fly in for a weekend of showings. Coordinate with your agent ahead of time so the paperwork is handled before you land. Do not assume you can walk into an open house or call an agent and immediately tour homes without addressing this step first. Open houses operated directly by a listing agent or brokerage have their own rules, so it is worth asking your agent how those situations are handled.

For sellers in San Antonio neighborhoods like Alamo Heights, Leon Valley, or Shavano Park, this law does not change how you list or sell your home, but it does affect the buyers walking through your door. Every buyer who tours your property through a buyer's agent will have a written agreement in place, which actually adds a layer of structure and seriousness to the process.

Renters and current homeowners are not directly affected by this law, since it applies specifically to the purchase of residential property. However, if you are a renter in the Southtown area or near UTSA who is thinking about making the jump to homeownership in 2026, this is something to factor into your planning as you start conversations with agents.

The bottom line for buyers is straightforward. Do not be surprised when an agent asks you to sign something before showing you a home. Read the agreement carefully. Ask questions about what services are included and what the compensation terms mean. Know that everything in that agreement is negotiable. And remember that having these terms in writing from the start is designed to protect you, not complicate your home search.

San Antonio's real estate market moves quickly in many areas, and being prepared means you will not lose time on a property you love because paperwork caught you off guard. Start the conversation with your agent today.
