OK, so DFIL passed this week. He and MIL had a very...strange relationship, but the upshot is that my MIL has refused to have much of anything to do in regards to the finances, taxes, and their trust.
It is a standard (for CA) A-B trust, and has now become irrevocable with DFIL's passing. Their house is in the trust, along with their bank accounts.
Luckily, we were able to find a copy of their trust (and *that* took a lot of time and effort), so we have the complete document. I am assuming that once we have a death certificate, we need to do some sort of estate bank account, and re-title the house into the B trust.
Does anyone have a checklist for things to do when one member of the couple passes? I think it would be very useful to have such a document for MIL - she does OK when she has marching orders, but I've never had to go through the legal motions for an established trust.
All advice appreciated!
