My mil died in 2014 and one of my wifes sisters was executor of the will. Everything went smoothly with sale of modest property and dividing up personal effects etc. They kept the po box for over a year after her passing to clear up all left over medical bills and also her bank acct remained open until nothing was coming in the mail except junk. My sil got a statement from Tricare yesterday with a balance on an ambulance trip for something that happened in 2014. Her net worth was dispursed sometime in 2016 and all accounts closed out. In my humble opinion she should tell them to go suck on a rope but legally I don't know for sure.
