Texas Agency Relationships

Agency law in Texas is governed by the Texas Real Estate License Act (TRELA) and common law principles. Understanding agency relationships is critical for the Texas state exam.

Important: This section covers Texas-specific agency law. For general agency concepts, see our Real Estate Salesperson exam prep.

Types of Agency Relationships

Texas recognizes three types of agency relationships:

TypeDescription
Seller's AgentRepresents the seller's interests
Buyer's AgentRepresents the buyer's interests
IntermediaryRepresents both parties with limitations

Single Agency

In single agency, the license holder represents only one party:

  • Seller's Agent - Owes fiduciary duties to seller
  • Buyer's Agent - Owes fiduciary duties to buyer

No Subagency Default

Key Point: Texas eliminated subagency as the default relationship. A cooperating broker working with a buyer is not automatically a subagent of the seller.

Brokers must establish their agency relationship through:

  • Written buyer representation agreement, OR
  • Acting as the seller's subagent (with agreement)

Fiduciary Duties (OLD CAR)

Texas agents owe six fiduciary duties to their clients, remembered by the acronym OLD CAR:

DutyDescription
ObedienceFollow lawful instructions
LoyaltyPut client's interests first
DisclosureReveal all material facts
ConfidentialityProtect client's private information
AccountingAccount for all money and property
Reasonable CareUse skill and diligence
