MIL is dying and has probably a few weeks left. No will or lasting power of attorney, not compos mentis so can't try and get this done now. FIL died 2 years ago so just DH and his brother, but DH's brother is estranged, nobody has seen or heard from him since FIL's funeral. DH is therefore dealing with everything alone.
MIL doesn't own her home or car. No investments, no private pension. MIL was a bit of a hoarder so while there is expensive stuff in her house e.g jewellery, kitchen gadgets etc, there is also a lot of junk/rubbish and she had a tendency to squirrel precious stuff away so every drawer, cupboard or box you have to go through with a toothcomb.
2 weeks ago when found out how ill she was we discovered that she hadnt been truthful about how much money was left to her by her parents who died 18 months ago (without a will) but she had lasting power of attorney so their accounts just moved into her name. She has other siblings but all were estranged from her parents and got nothing. Worth noting that all the relationships in MIL's family are complicated and there is a history of just about every kind of abuse you can think of.
What happens to her accounts when she dies? I did some research and think it goes to probate (we have found bank statements and believe it is just over £30k), funeral and debts paid out from that then remainder goes to intestacy and split between DH and his brother. DH thinks his brother gets everything as he is older than DH. I am presuming inheritance law doesn't take family politics into account?!
(Make a will folks. Especially if you've got odd family dynamics going on. Please don't give your loved ones this pain to deal with)
