So let me ask you, if they tell you they are ok and to mind your own business (not as crappy as that but you get the idea) would you respect them?
Or better yet, what if they tell you and you don't agree with their plans what are you going to do, force them to spend the money or invest their money the way you want?
I'm not talking about incapacitated parents. I mean fully functional parents who's only crime is that they are elderly.
This is where we stand with my IL's and it makes me literally sick at heart. They have spent a lifetime bailing out my BIL financially. We finally got them to agree to sell their house this summer to get out of the terrible debt they had gotten in. They were able to settle into a lovely apartment with some savings. Now, six months later, we find they are again over $20,000 in debt because they simply cannot say no to their (alcoholic) son. They are 82 and 81. I don't know what's going to happen but I suspect they will at some point be forced to live with one of us due to poor decisions on their part. I know we don't have a say in how they spend their money, yet it WILL, without a doubt, become OUR problem before too long.
I don't know the answer. I never would have considered involving myself in my parents' financial affairs but they never had any issues. Because my dad was so good financially, mom is able to live out her final years in a luxury retirement place and I'm thankful every day that he made that happen. But my IL's will never be able to do that and it makes me sad and angry.
