re: Spouses involved in succession

If the will says sell the property and split the proceeds, your sister (the executor of the will ) should tell your SIL to sit down and shut up and do what she needs to do.

I was the executor of my grandfather's will (grandmother had already passed) and my aunts were pissed about that. No fricks were given. I handed out property that was specifically stated to go to certain people and sold the rest and split the proceeds according to the will. My aunts started out "you should do this " and "you should do that" I shut that down quick. It only takes one person to sell property, not one person , his mom and 3 aunts.
