“After three years the Judge at the Settlement Hearing today deemed that my verbal acceptance of the bid is a binding contract. Is this correct. (In the Circuit Court of Maryland, Elkton MD).”
What does your lawyer say? You do have one, right?
In general, a verbal acceptance of an offer can form a binding contract. In the case of the sale of real estate, however, most states still have the rule from the Statute of Frauds that a contract for the transfer of real estate must be in writing to be enforceable. That said, there are exceptions to that rule, and the exceptions vary from state-to-state.
Without knowing all the details of your case and exactly what the judge determined, it is impossible to know if the judge was correct. Since this was a comment made by the judge in a settlement conference, it is probably not a formal ruling of the court on the issue and not a final determination on the case, so it is likely that you cannot yet appeal the judge’s determination. Instead, it sounds like a comment the judge made in the context of trying to get you to reach settlement on this. But what you really need to do is consult an attorney asap since there may be limited time for you to act on this, whether it's the settlement, an appeal, or whatever else is appropriate. There is no way anyone here can tell you what the right answer is in your case or how you need to proceed.
