Legal Question in Wills and Trusts in Illinois

Could be a legitimate request, but obviously an attorney would need to look over the relevant documents, including the will to be certain. Who sent him the letter?

Hard to tell for certain, but it sounds like maybe the house is the only asset and they are trying to use a bond in lieu of probate to sell or transfer the house. For a bond in lieu of probate, the title company is probably going to require that all heirs, including disinherited heirs, sign off on the validity of the Will. Otherwise, your husband could later go into Court and attempt to contest the Will or have it said aside, and the title company could have liability.

Of course, that's just my suspicion from what you posted, it could be something else entirely. Your husband should have an attorney look over the documents and advise him.

Boy, that's an excellent question. You have good reason to be suspicious. I suggest that you tell your husband's sisters to provide an explanation in writing. Then, take that explanation, along with the previous letter that your husband received, to an attorney who practices in estate administration. That attorney will be able to help you sort this out, and may do so as a free consultation. In fact, if you'd like to provide these items to me, I'd be happy to provide a brief, free consultation about this at no charge. That might be all that you need.
