I’m with Kicksave. Just becuase the owner is in bankrupcy does not mean she does not own the house or that your rental agreement is cancelled. She SHOULD have you listed as a source of income in her bankrupcy petition, and she SHOULD be collecting the rent from you to pay off those to whom she owes money. The amounts involved may be small enough that no one thinks its worth pursuing you, and you may get lost in the shuffle, but as long as she is providing you a habitable house, you legally owe rent and the owner- or someone the court appoints to collect her money- might come after you.
Holding the money in your bank account might be the best choice under these circumstances, but don’t plan on spending that rent money yet.
