Yes - this is so insightful.This is why I find the kids irresponsible. If you hate the old man so much and cut ties with him, don't fight for his money. If you want your old man's money, be nice (while he was alive). Plan a funeral. Do it for the public, at least that would look nice in the legal battle to the judge.
And as far as kids declining inheritances from estranged parents, FTLOG take the money and donate it to animal rescue or other worthy causes.
