Monique tells her letting agent in writing: 'You may sign tenancy agreements on my behalf for my flat at a rent of at least £1,200 a month.' What type of authority does the agent have to sign a tenancy at £1,300 a month?

Correct answer: D) Express actual authority

Explanation

Express actual authority is authority the principal gives the agent expressly, orally or in writing. Signing at £1,300 falls within Monique's written instruction. Apparent authority comes from a representation to a third party, ratification happens after the event, and agency of necessity arises only in an emergency.
