It they filed a chapter 7 - I wouldn't give them another dime until the closing. However, you stated they filed a reorganization - that's chapter 11 (chapter 7 is liquidation).
If there is any issue - I would go to the bankruptcy court and ask them what to do - I would give no one any monies without knowing I'm protected and going to get the property pursuant to the contract and not be paying for anything extra whatsoever.
If you don't have an attorney I would most certainly tell you to get one at this time under the circumstances. They should be able to review the paperwork and will advise you not to give anyone any monies for anything - to wait until the closing - even then (at closing) to make sure you get clear title to the property before you give them any monies.
