No. The principal must give written consent before a Florida single-agent relationship changes to a transaction-broker relationship. A verbal announcement or an assumption that the seller will not mind is not the required consent.

Florida Statutes section 475.278 sets out the transition and its disclosure requirements. Florida permits single agency and transaction brokerage, but not disclosed or undisclosed dual agency. A transaction broker provides limited representation rather than the fiduciary representation of a single agent.

Consider a hypothetical listing. A seller has agreed to single-agent representation. Later, a buyer approaches the same brokerage, and the brokerage proposes a transaction-broker arrangement. The seller's earlier listing agreement does not, by itself, make every later change acceptable. The brokerage must handle the required disclosure and obtain the seller's written consent before the transition.

It helps to separate three questions:

• What relationship exists now? Check the actual agreement and disclosures.
• What relationship is proposed? Explain the difference in representation, not just a new label.
• Has the required consent been obtained? Complete the applicable process before acting under the changed relationship.

Do not confuse Florida's presumption of transaction brokerage with permission to override an established single-agent arrangement. The presumption is not a substitute for transition consent. If the principal declines, the brokerage cannot treat silence or continued negotiations as the missing written approval.

For a real transaction, use the broker's compliant disclosure procedure and obtain legal guidance if the documents or relationships are unclear. This study explanation is not a replacement disclosure form. Our brokerage relationships guide compares the duties that continue with those that differ between the relationships.
