Quick claim deed

My friend is older and was very ill. He was going in the hospital to have bypass surgery where they didn't expect him to survive. He did a quick claim deed and had it notorized the day before surgery to allow his son to take care of the properies until he rocovered and or to distribute the the property if he passed. It has been three years and he is alive and well but his son refuses to give reverse the quick deed. He is still paying the morgage on one the properties. Does he have an leagal right to his properties?
