Consent to transition from single agent to transaction broker in Florida must be:

Oral consent is insufficient because Florida law specifically requires written documentation for agency transitions. Verbal agreements don't provide the clear record needed to demonstrate the client's understanding and agreement to change their level of representation.

Implied consent cannot be used for agency transitions in Florida. Agency relationship changes require explicit, affirmative consent rather than assuming agreement based on a client's actions or silence.

Notarization is not required for consent to transition agency relationships in Florida. While some real estate documents require notarization, this specific consent only needs to be in writing to be valid.
