Your FIL is in charge. Whatever plan you come up with probably won't mean squat. The transfer will move along at his pace and on his terms. I know you are anxious but he has got 7 other people to run this idea to first. He will come back with a plan for you in 2 weeks after the lawyer meeting. Don't get pushy but indeed stay connected with him on the matter.
This is my advice after being involved in the almost identical situation.
