Can our bankruptcy attorney take a percentage of the money being held by the trustee?

Your bankruptcy attorney only gets paid the amount you agreed in your contract with her. No jurisdiction allows an attorney fee which is a percentage of the payments.

Your concern makes no sense and I expect you misunderstood your attorney. Read your fee agreement? it will specify how you pay your attorney. Your trustee is paid a percentage of any assets that are not protected by an exemption. Your attorney is usually paid by a flat fee for a set of services, and is paid by the hour for additional work required. And meeting with you to ask more questions about the fee is generally considered to be additional work, as these questions should have been raised before you signed the fee agreement.

I would suggest you meet with an attorney face to face to ask your questions. Anyone giving you an answer without looking at your BK file, including the fee agreement, would be guessing. It's like trying to ask a doctor by phone, whom you have never met, to give you an opinion about Xrays taken of you a year ago, and asking the doctor to hazard a guess about what the Xrays mean.

All bankruptcy cases are managed by a trustee. Attorneys fees can be paid from the BK plan and the Trustee is paid as a percentage of the un-exempted assets of the case.
