I have changed my mind to rent a berth I own for a boat via a broker, as I have sold it privately.
The broker emailed me with details for renting from April 1st. I send an email to agree. Five days later before I had received a contract I emailed to say I had sold the berth and therefore would not proceed to rent it for a year. Is there any come back please as the broker is asking for compensation? That day he received a deposit from his client.
I don't think there is enough information to be confident of the answer here.
On the hand, it could be an unenforceable "agreement to agree"; on the other, it could be an enforceable contract. A lawyer would want (amongst other things) to discuss the surrounding circumstances and look at the chain of communications before advising.
