So @Zamboni several things: first, and most important of which is THAT I AM TERRIBLY SORRY YOU AND YOUR SO ARE HAVING TO GO THROUGH THIS! That can't be said enough. This is not normal or humane behavior.
Seriously. You two may want to consider something that has helped us in the midst of awful situations: go out and have some fun some nights and try to forget about all of this. I know it's hard to do that in the midst of a tragedy, but it's also the best medicine, as folks have reminded me over the years (because I'll let the stress of it get to me).
Now, I can help as to where this is headed, as I have experience dealing with (lots of) conflicts and unreasonable situations. Actions speak louder than words, and this started with outright fraud and seizure of things that DotL (for short) had no business taking.
It's headed towards outright fraud and theft. She's going to camp on the estate, control it, and drain every thing of any possible value. It's already underway.
The estate will continue on until she converts everything that she possibly can into cash for herself, the estate goes bankrupt, and things get seized. Her cash problems will only hasten the speed of the theft.
This is someone who does what she wants, not someone who cares about paperwork, laws, and rules--that much she has shown you. I hate to tell you this, but to prepare yourself, I would prepare for maximum ugly here and start establishing those boundaries so that you can stay out of and above the drama.
Eventually, you're likely to need hard no-contact rules. Why let her drag your own emotional lives down, rather than shut her off for periods of time, and/or mediate it through a lawyer/trusted friend/someone else/ignore her completely, so that you can stay away from it all. That path is going to get increasingly attractive over time.
As I see it, there are two paths here: SO can either jump in, take over the estate, and fight it out (or, rather, employ the lawyers to do so), which would be a large emotional lift and expensive due to DotL and her inevitable shenanigans. Or you both can walk away, let her trash it all, ignore it all as it circles the drain, but preserve more of your peace and sanity. And nothing is worth more than peace and sanity...once you don't have it anymore.
Anyway, I'm sorry once again and wish you nothing but the best in dealing with a truly awful situation. There's nothing like death and money to bring out the worst in some people. But thankfully you two have each other to get through this and stay above the fray.
Thanks again for this. We decided to go on vacation to a tropical paradise this past weekend . . . that was a great idea!
Your predictions are so spot on.
Updates about the Destroyer of the Last Will and Testament (DotLWaT!, DotLW for short):
-DotLW got so mad that Mr. Zamboni wouldn't send her money for "the bills" that she threatened no contact with him . . . a threat that of course she just can't make good on because of her continuous need to send rude texts and demand things. And then there was the whole emergence of another copy of a will wrinkle she hadn't anticipated. So she's already followed up several times since then. *Eyeroll*
-Mr. Zamboni has decided that No Contact with DotLW is the only sane strategy from his side . . . so he is not responding.
-As far as I can discern, the named executor in the only copy of a will anyone has seen beside DotLW has thrown in the towel and given the reins over to DotLW. Honestly, everyone is just quietly backing away from the mess with their hands in the air. Other sane sibling is also just saying "whatever, do what you want, but I'm not giving you money" to all demands.
-DotLW has communicated that she is going to obtain the divorce finalization paperwork from the court to negate the named sole inheritor in the will from getting anything. No idea if this is how it works or not, and no idea if DotLW has sought any legal advice.
-DotLW has sent copies of credit card receipts for what she paid for the hastily solo planned over-the-top funeral/burial. Oh, Lordy, I guess it's no surprise that she spread it out over several different credit cards even to the same funeral home. Predictions that she is in financial trouble coming true. She appears to have bought the most expensive plot at the most expensive cemetery in town. Despite the deceased belonging to a large local church for decades, she paid extra to have the service held in the chapel owned by the funeral home instead. And despite having to charge it all on various cards, she is still vowing to spend over $4K additionally for a headstone which she is picking out. According to her texts, she IS doing this and she WILL get her money back and no one better stand in her way! No one else is on board with her plan. Seriously I've purchased cars for less than this theoretical headstone.
-DotLW is whining to extended family that people are not jumping in to pay her back for her ridiculous choices.
-DotLW also sent a copy of her bank statement showing that she is paying the bills of the deceased. These include normal things like utilities on the home and absurd things such as renewing an AARP membership (Um, why?) She is paying these from her personal account, rather than an established estate bank account.
-Although DotLW once said she planned to move into the house left by the deceased, she has reversed course and now says she plans to sell it.
