No will, no estate planning, no lawyer.
Yikes! Is there any way you could tactfully convince her that maybe she should be thinking of taking care of that?
My husband, when asked by his parents what he wanted for Christmas, said the only thing he really wanted was for them to write a will. Not because he wanted their stuff, he didn't care if they wanted to leave every cent to his brother. But because he and his brother have a new and tenuous relationship
that has recovered from a great deal of strain, and they're working hard to mend it. He's seen what problems can be caused by an unfair will or by things not made clear (in the family, a particularly elderly woman of the type who loves to play favorites left almost everything to one nephew, and left a pittance to a niece who had been one of the ones who frequently visited and helped her, etc.). He wanted to make sure that when his parents died, it would be utterly clear who got what and they wouldn't have any need to argue over it.
