Good Luck. Death and money cause such interesting interactions.
We got no accounting of FIL’s estate. Nothing, nada, zip. DH got a check.
Our attorney said we could send letters asking for an accounting, and the state would fine the executor $1000 for every one he ignored. But we knew the best he could do was make stuff up because he hadn’t kept records along the way, so there was no point to it.
It sounds like this is not about the money, it’s about broken relationships. You may be in for a long ride.
