Can partition take place if not on the title?

Absent a written agreement, the broker has no remedy at law. Even if he could prove that you orally agreed to put him back on title or to partition the property with him, oral agreements concerning real property are unenforceable under the so called Statute of Frauds. And even if the broker could prove an enforceable contract, his remedy would be limited to money damages in the amount of the fair market value of his claimed share of the property. I suppose the broker could file some sort of proceeding in equity (e.g., reformation). But if he cannot prove that he contributed money to the acquisition of the property, then he cannot prevail. However, you should not rely entirely on the opinion of a LawQA attorney who has not heard all the facts and has not reviewed relevant documents. I urge you to seek an in person consultation an attorney specializing in real estate law. Your county bar association may have a lawyer referral program that will arrange a consultation with an attorney in whatever specialty you need for a nominal fee.

I can't answer that question, since it involves technical real estate advice. You will need to consult with a real estate attorney in order to straighten this matter out.
