Legal Question in Business Law in Pennsylvania

Re: Legally Binding

Unfortunately not just a somple answer. Agreements for certain subjects must be in writing to be enforceable under the "statute of frauds". Other agreements may only be partially enforceable depending on the subject matter. Even if legally binding, you will run into evidentiary problems if you try to enforce an oral agreement. At a minimum you want a letter confirming the agreement, which is not always sufficient to prove an agreement.
