The bill of sale and SF-97 will only work if you have the exact same name and address of who bought it in the peoples republic of MD. Maryland , like most states want to see the buyer, with SF-97 and GL Bill of sale, in hand, and they use these to get the title. Then that title can get transferred to the next person. I could not skip the step even to a family member, son, if they were present at the MV More steps equal more money!!!! Also, the international title companies have tightened up of granting titles for vehicles. Some states have slack rules on trailers but there are less and less of them.
