Sadly for me, I am going through this right now with my wife and her sister. The Mom passed and left them both a ladybird deed in their names, and before she died insisted they work together to finalize her estate. It has been anything but that! The sister does nothing, she’s “too overwhelmed”, both at home and with the situation. There’s a property line issue that I’ve been entrusted to fix, which I’ve had no problem doing, except for the fact that the sister “just wants it done”, but does nothing to help. I’ve spent hours upon hours with the lawyers, the folks who are involved, the buyers who are waiting patiently, and I ask nothing for my time or effort. Of course tho, I’m the asshole as always. My wife made me fill out a list of everything I’ve done, from clean out the house, fix it up, paint the entire place, and do all the legal stuff. I have a very low estimate of 100 hours and almost $9k into this, and I want nothing but to be done. We just turned in the bill, as the property line issue has been resolved and they are ready for a closing. I’m waiting for the **** storm to start because of the bill. For a pair that was supposed to “work as a team”, it has been anything but. I keep telling my wife that if she wants any kind of relationship with her sister, they have to work together on this, but sadly so, that never happened, and now won’t. In the end, I’ll be the asshole to my SIL, because in her eyes, that’s what I am. I just want to go back to the relationship I’ve had with her and her husband….NONE. I just want my time and sanity back!
