Long story short, my husbands mother had a mental breakdown during covid, and now has to have 24 hr live in care. The father has sadly already passed and all her affairs have been left to her 3 children to sort out as she's incapable of making a decision. The 3 siblings share POA over finances and her health. My husband (eldest) is a sole trustee along with his mother on trusts that hold several properties and portfolios.
There's been a big fall out with the sister over the mothers care (she wants to do it her way, ignoring the wishes of the other two). One brother hasn't spoken to her for almost a decade over a separate issue, and my husband is getting very close to cutting her out completely. She's impossible to communicate with as most of her messages are entitled and vitriolic in nature, you cannot make firm decisions on anything as she changes her mind at a moments notice. This obviously causes him great stress, and in turn us as a family.
The latest issue is she's started to make it difficult for my husband to make changes to the properties that are in the trust. He would like to rent them out, so he isn't lumbered with having to sort out their maintenance etc, especially as none of them live nearby and also help to cover the mothers care costs, but she's said he cannot do this and they 'all have to agree as a family' (the irony...) when in fact legally its actually just him and his mother. The sister has also just started to take large withdrawals from the mothers bank account, significantly over the amount required for her care costs.
It's all getting really nasty and I feel for my husband who's now receiving counselling to help deal with it all.
Has anyone been in this situation before and can offer any advice? Can you appoint a solicitor/accountant to act as a 3rd party, how does this practically work?
