I'm Getting Bills for My Wife's Nursing Home Care While Waiting for Her Medicaid Approval

You might be responsible, but I would hold off until you learn whether Medicaid has been approved and for what date. It will be a lot easier to pay what you may owe than to recoup what you have already paid. In terms of accounts, you will need to keep any account in your wife’s name under $2,000, so you should transfer virtually all funds into your own name in any case.
