I'm in Florida and this is a question concerning contract law.
My boyfriend's exwife had me sign a notarized letter stating that I would give her my car and my boat and my boyfriend would continue to pay the same amount of child support (he pays extra to pay off arrears) and she would remove the arrears. I signed to her old titles to the boat and car (they're void because I ordered new ones) and she will not register them until the judge finalizes the petition to drop arrears.
This all started because my boyfriend could not renew his passport until the arrears were paid or dropped. She saw that we were in a difficult position and took advantage (the agreement states that he'll still pay the current child support and arrears).
Now I'm feeling skeptical about having signed all this. In the letter, she stated that I was his fiancee, which is not correct. We live together and he is married but separated. Can I get out of this agreement? This all happened overnight and I feel that I was ambushed by both of them. What are my chances on sucessfully rescinding on this agreement?
I'd really appreciate any feedback on this matter.

Simply getting something notarized doesn't create an enforceable contract - especially in child support cases, where the judge, and ONLY the judge, gets to decide what happens. SHE doesn't have the legal authority to remove arrears, even if she wanted to, nor to barter for alternative forms of payment.
