Be honest...the courts are closed and he probably knows that. However, you can advise him that the lawyer has been in contact w/you and advised you that the vehicles can be paid off with the marital assets.
If he should question about the release of funds for the purchase of another home, then I would advise him that he needs to speak to his lawyer about this particular issue. The reason that I am saying this is he needs to be speaking to his own lawyer about it because he may not accept what you tell him about it. For one thing, if I were in your shoes, I would never agree to allowing him to use marital assets in purchasing another home unless I were going to be living in it. BTW, if he purchases another home w/martial assets, that home will come into play when it comes to splitting up of marital assets and your lawyer just very well may go after 1/2 of that particular asset.
It's not your job to be advising him of what your lawyer tells you. Remember...your lawyer is representing you, not him. He's a grown man and should be working w/his own lawyer and if doesn't have one...then he needs to get one. Keep your cool and be very up front and honest...do not share anything more w/him that your lawyer tells you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
