My adopted son has a piece of property that was deeded to him by his biological grand mother she died why he was in prison and his bio mother was living in an old mobile home on the property,that was his grandmas, the moble home has a large attatched rm and porch that is all so attached to a pole barn. Because the deed was for the property and the trailer is not mentioned in any will his mother, because at one time it was titled, says its hers and he cannot live there,because its attached to permanent structures on his land does it make it his?
