This is going to get complicated. Weiland's debtors have to be paid upon his death, and the money specifically comes from the estate. I have a friend who is a family estate lawyer, so I will have to check with her on the details.
What complicates things is who the executor is, and Mary has sued saying she is the executor. I know for a fact from my lawyer friend that there is no mechanism in place to make sure the executor does his or her job. We had this happen to my great aunt who had stopped contact with the family. After 15 years or more, my mom got a phone call from a service that calls seniors each morning to make sure they are okay. My mom happened to still be the emergency contact all these years later, and the service felt as if my great aunt didn't sound right, so they called my mom. Turns out dementia was well underway, some neighbor had wormed her way onto the checking account, bags of cash were stashed around the house, and we have no idea how much the neighbor stole, nor can we prove it.
The aunt eventually died, and the executor of the trust was someone none of us knew, he no longer did that kind of work, but he still executed trusts he had set up on the past. The will said that all of her assets were to go to some feline charity.
Well it's been almost 2 years now, and the executor of the trust has not paid the charity. He has full access to her bank account (it was in the low-mid 6 figures). That money and the money from selling her house should have been paid to the charities. It still hasn't. In fact, he has been renting the house and (presumably) keeping the money. We do know that the executor lost his job and his wife lost her job around the time this all happened, so my mom being very religious believes that they need the money more than the cats (we were all shut out of the will), so she is not interested in turning them in.
I asked my lawyer friend about this, and she said there is no mechanism, no checks or balances. The executor is simply trusted to do what the will says.
Obviously this is a higher profile case, but if Mary has the will and she is the executor, maybe she is legitimately concerned that things could be sold or stolen out from under Scott's wishes in the meantime. Maybe she just wanted a guitar. Maybe she is the executor and can do what she wants. If that is the case, no one may ever know what is actually supposed to go where.
