Understanding Brokerage Services in Texas. Our Texas Real Estate Commission believes that consumers should understand the basics of agency law and fair housing requirements and understand that license holders will not abrogate those principles. This is a simple Form and a informative form explaining how brokerage works in Texas. This from is required by Texas law to be given to prospective buyers, tenants, sellers, and landlords. IABS and Consumer Protection Notice are statutorily required forms for consumer information to help ensure that consumers of Real Estate Services better understand how a broker or agent can represent them and where to find help if they need it.
