Missouri: buyer-agreement requirements.

This page lists what Missouri requires, at the state level, before a licensee represents a buyer: who regulates real-estate licensees, whether a written buyer agreement is required by state law or rule, the statute or rule that says so, and whether the state mandates an agency-disclosure form or publishes an approved agreement form.

It is built for broker-owners and transaction coordinators who need the state rule in one place before setting office policy. Read it alongside your brokerage's own forms and your broker of record's guidance — the written-agreement question became a national practice issue in 2024, but the rule that binds you is your state's, and it is the state rule this page cites.

Missouri, field by field.

Regulating authority

Missouri Real Estate Commission (MREC) — Division of Professional Registration

Written agreement required by state law

Yes

Statute or rule

§ 339.780, RSMo (Missouri broker relationships); ministerial acts defined at § 339.710; licensed activity at § 339.010. Read at revisor.mo.gov.

Agency disclosure form

Not verified. § 339.780 does not itself prescribe a disclosure form — Missouri's broker disclosure duties sit elsewhere in the chapter, and we did not read them.

State-approved form available

Not verified

Notes. 'Before engaging in any acts enumerated in section 339.010, except ministerial acts defined in section 339.710, a designated broker acting as a single agent for a buyer or tenant shall enter into a written agency agreement with the buyer or tenant.' There is a parallel rule for transaction brokerage: a designated broker who intends to act as a transaction broker and who expects to receive compensation from the party assisted 'shall enter into a written transaction brokerage agreement.' Both must state the duties and responsibilities and the compensation terms. The live question in practice is the carve-out — ministerial acts under § 339.710 do not trigger the requirement, so get your broker of record to define in writing what this office treats as ministerial before an agent has to decide it standing in a driveway.
