There are attorneys who specialize in, or at least partly specialize in (it's one of their main practice areas), defending people from foreclosure actions; such a lawyer would be the best choice, because even though your uncle is not necessarily trying to save the property from foreclosure, foreclosure law is involved as are court rules and proceedings--thus, a lawyer who defends foreclosures in court would be able to help him. Your uncle may be able to get a referral to such lawyer from the state bar association; a "Google" search would also turn up such attorneys.
