Sorry, I figured as long as we were asking non-sensical questions, I'd throw my hat in the ring...
There are three BIG FLASHING RED LIGHT OPTIONS available to you that you should peruse first.
#1. Chat with husband. You would be surprised how well that works....unless you are suing him already.
#2. Chat with the agent.
#3. Chat with the agents broker.
Without your co-operation, the home CAN NOT BE SOLD! No one wants to waste their time and resources.
But your first thought was find someone to sue. There is not an attorney in the state of Florida who would not welcome your money. What you expect the outcome to be, however, is a mystery.
Your husband is presumably an adult... and he knew that he was signing without your knowledge... your issue should be with him.
Can you sue? Of course you can.... but whether you will win is entirely up to the facts of the case, and my guess (yes, it's a guess... I'm not a lawyer and this is not legal advice) is that the judge is going to side with the Realtor....
if you have a problem with this contract... the party to talk to is your husband. If he forged your signature, or signed a contract that binds you as well.... he should be sleeping on the couch for a while... but unless you have some facts that truly implicate the Realtor... stop trying to drag him/her through the muck.
Best of luck.
