My brother and I sold a property we owned together. My brother has liens against him. The attorneys are holding a portion of my share of the money

You should not have signed the deed without getting the money.  Whether it is "legal" depends on what you signed.  You should have had separate counsel.  At this point you need a lawyer to look at the closing and determine what you should get and what you owe.  The lawyer clearly has a conflict, and you should fire the lawyer.
