Are the courts allowed to reform a contract that as a member of the chain of title I did not agree to.

Courts can reform a contract, but do so extremely rarely.  The main grounds for reformation are mutual mistake (where ALL parties to the contract are mistaken about a material fact underlying the agreement) or fraud (where one party lies to another about a material fact, and the other reasonably relies upon that misrepresentation in entering into the contract).  Neither seems to apply to your situation.  I don't know what you mean about being a member of the chain of title, but if someone agreed to something on your behalf, without your permission, and didn't have your authority to do so, you may be able to get the contract rescinded, but it is  unlikely that you will be able to get it reformed.
