The Short Answer: Yes, Before You Show Property
Under TRELA Section 1101.563, enacted by SB 1968 and effective January 1, 2026, Texas agents must have a written buyer representation agreement in place before showing any property to a buyer. Open houses are not exempt. If you are acting as a buyer's agent and accompanying or meeting a prospective buyer at an open house, you need a signed agreement first.
This is one of the most commonly misunderstood rules in Texas real estate right now. Agents assume that because the door is literally open, the legal requirements relax. They do not. The obligation tracks to the relationship between agent and buyer, not the format of the showing.
Why Open Houses Cause So Much Confusion
The confusion stems from a fundamental misunderstanding about who the open house serves. When a listing agent hosts an open house, that agent is representing the seller. Walk-in visitors who browse on their own, without a buyer's agent present, are not being "shown" the property by a buyer's representative. No buyer representation agreement is triggered in that scenario because no buyer-agent relationship exists.
The rule changes the moment a buyer's agent enters the picture. If a prospective buyer contacts you, asks you to meet them at an open house, or expects you to provide guidance at the property, you are now operating in a representation capacity. TRELA Section 1101.563 requires the written agreement before that interaction begins.
The Listing Agent's Role at an Open House
If you are the listing agent hosting the open house, you do not need a buyer representation agreement with walk-in visitors. You represent the seller. Your duty is to the seller, and you are marketing their property. However, you cannot provide buyer-side advice, negotiation guidance, or representation to an unrepresented visitor without first entering into a written buyer representation agreement — which would also create a dual agency situation requiring separate disclosure under Texas law.
Which Agreement Form Should You Use at Open Houses?
Texas REALTORS® provides three buyer agreement forms, and the right one depends on the scope of your relationship with the buyer. For open house scenarios, two forms are particularly relevant.
- TXR 1507 (One Property/Day Agreement): Limited to one specific property or one calendar day. Ideal for a buyer who asks you to meet them at a single open house with no ongoing commitment.
- TXR 1508 (Showing Only Agreement): Non-exclusive, capped at a 14-day maximum term under TRELA Section 1101.562. Covers showings only — no representation or advice. Useful when a buyer wants to tour multiple open houses over a weekend without entering a full representation relationship.
- TXR 1501 (Full Representation Agreement): Exclusive, full fiduciary duty, no statutory term limit. Use this when the buyer is ready for a committed agent relationship beyond casual open house visits.
For most open house encounters, TXR 1507 is the most practical starting point. It covers exactly one property, creates minimal friction, and satisfies SB 1968's written agreement requirement.
What About the TXR 1508 for Showing Only?
The TXR 1508 is sometimes misused at open houses. Remember: this form provides no representation and no advice. You are essentially agreeing to unlock doors and nothing more. If you plan to discuss pricing, neighborhood data, or negotiation strategy at the open house, the 1508 does not cover that activity. You would need a TXR 1507 or TXR 1501 instead.
Also note the hard 14-day maximum term imposed by TRELA Section 1101.562 on Showing Only agreements. You cannot extend a 1508 beyond 14 days. If the buyer relationship develops, transition them to a 1501.
The Four Mandatory Clauses Still Apply
Regardless of which form you use, the NAR settlement requirements effective August 17, 2024, mandate four clauses in every buyer representation agreement. Open house agreements are not exempt.
- Exact compensation amount: A specific dollar figure or percentage — no open-ended ranges.
- Source neutrality: Compensation may come from the buyer, seller concessions, or other sources.
- Negotiability disclosure: Must appear in conspicuous text stating that compensation is negotiable.
- Specific services: The agreement must list the exact services you will provide.
For a TXR 1507 at an open house, the services section may be brief — attending and evaluating one property. For a TXR 1501, it will be comprehensive. Either way, all four clauses must be present.
Penalties for Noncompliance
TRELA Section 1101.563 violations carry real consequences. TREC fines start at $1,000 per violation, and license suspension is possible for repeated offenses. Showing a buyer a property at an open house without a signed agreement is a violation — full stop.
Beyond TREC enforcement, TRELA Section 1101.806 reinforces the Texas Statute of Frauds: all real estate agreements must be in writing to be enforceable. If you provide representation at an open house without a written agreement, you may have no legal basis to collect compensation even if the buyer later purchases the property.
A Practical Workflow for Open House Compliance
Here is a step-by-step process for buyer's agents handling open house requests in 2026.
Step 1: When a buyer asks you to attend an open house, send them a TXR 1507 (One Property/Day) agreement electronically before you meet. Under the ESIGN Act (15 U.S.C. § 7001), electronic signatures are fully valid for real estate agreements as long as the signer consents to electronic business.
Step 2: Confirm all four NAR mandatory clauses are present in the agreement — compensation amount, source neutrality, negotiability disclosure, and services list.
Step 3: Receive the signed agreement back before you arrive at the open house or before you begin providing any buyer-side guidance at the property.
Step 4: If the buyer wants to continue working with you after the open house, transition them to a TXR 1501 Full Representation Agreement for ongoing services.
Step 5: Store the signed agreement in your transaction management system. TREC can request proof of compliance during audits.
What If a Stranger Approaches You at Your Own Open House?
This is the scenario that trips up listing agents most frequently. You are hosting an open house for your seller. An unrepresented buyer walks in, loves the property, and asks you to help them write an offer.
You cannot represent that buyer without a written buyer representation agreement. Period. You also cannot provide negotiation advice, suggest offer terms, or act in any buyer-agent capacity without one. If you want to represent both sides, you must execute a buyer agreement with the required four clauses, disclose the dual agency situation, and obtain written consent from your seller as well.
The safer approach: hand the unrepresented buyer a list of other agents, or direct them to find their own representation. Protect your seller client and your license.
Bottom Line
Texas law does not carve out an open house exception. If you represent a buyer at any property showing — including an open house — TRELA Section 1101.563 requires a written agreement first. Use the right form for the scope of the relationship, include all four NAR-mandated clauses, and get the signature before you walk through the door. The $1,000-per-violation fines and potential license suspension make shortcuts indefensible.
