Even if we were the sort that would wait around for an inheritance, we still would be lucky to get any.
My Dad died several years ago now and nothing came my way (not that I wanted anything). Mum lives in a Retirement Home, spending her pension each fortnight. There will be nothing left.
Hubby's father died a bit before mine. Again, I think he got a circular saw, which promptly died too. Nothing else! When his mother passes, well, she owns her home (unlike my mother), but Hubby is the youngest of seven and she has something like 27 grandchildren and I can't remember how many great grandchildren, so it is possible that nothing much will be left there either, depending on how she chooses to make the split.
As far as I am concerned, I am more than happy for her to spend it all. It belongs to her, after all. She should enjoy it.
With our kids, we have discussed investments many times over the years. They have a head start in the knowledge stakes that neither Hubby or I had, so they should both be able to look after themselves. We won't be storing up money just to give them both an inheritance (sorry Lil), as we intend to enjoy ourselves with what we have achieved.
