my MIL recently died, her sibling was sole power of attorney, over the past couple of years various family members had concerns about this as they felt she wasn't always acting in the best interests of MIL. We tried to raise it with Mil, her sibling and social care as she was severely disabled but it would end up with Mil becoming distressed and insisting she was happy with her sibling being POA so we left it.
Upon MIL's death, we found out my DP was the sole executor of the will.
We closed the bank account earlier this week and asked for statements to check any DD or things we have missed when sorting out the estate.
We found POA had been using the account as her own, racking up between £1500-£2000 outgoings each month not including paying bills, mainly on supermarkets. In the last two years of her life, Mil was housebound and was visited by carers multiple times a day she also lost her appetite and was eating very little so even being generous her shopping costs would have been a maximum of £500 a month. Suggesting POA was spending a minimum of £1000 a month which was not for any benefit of MIL. We can see 5 months of this on the statements we have.
We have no idea what to do, we swing from wanting to call the police to just leaving it and cutting POA out of our life. We don't care about the money, but we are so angry she took advantage for so long when MIL was so trusting of her.
DP is worried POA will harm themselves if they realise they have been found out as it is something they have threatened in the past - he doesn't want that guilt on his conscious.
