Yea Scott. Just went through this when my Dad passed. It's worth talking with someone familiar with the appropriate state's laws.
Dad has a power of attorney but it was in case he couldn't manage his own affairs and was still living. Once he passed, that was void.
In CA, where Dad passed, they had a small estate provision. Under $100,000 was real simple; no probate. Since Dad had set up living trusts, those passed outside the estate. Same with insurance proceeds. Only left his bank accounts in the estate and they were under the $100,000 mark. Just had to have an attorney sign a small estate affidavit; copy of the will and letter from the executor with instructions. Couple banks gave us some grief, but it all worked out.
Hope all goes well. I know it's not fun.
Best,
Dave
