I'm not very well versed on legal stuff, nor do I own my own home, so forgive me if this is obvious.
My DF left his house in trust for me and my DB. My DM lives in it. When my DF bought they house they weren't married. They had been married, then divorced, then when DF found out he was terminally ill, they remarried so that DM would benefit from his pension.
The terms of the trust state that the house must be kept in good order. Sadly DM is a hoarder and has frittered away thousands of £ since DF died 23 years ago. The house has fallen into a state of disrepair and DM doesn't have any money to carry out some essential repairs and maintenance to get into into a reasonable state again.
I had a critical illness payout last year and have the money available to tackle the house and get it in order with a view to selling it and buying DM a small apartment or similar. She has mobility issues and cannot easily get upstairs or even into the garden anymore. I'm happy to finance the renovations - it will need a massive de clutter, decoration, garden clearance and probably a new kitchen and bathroom. I don't for one minute think my DB will diddle me out of the money when the time comes, but I do want something drawn up legally so I can get my money out at some point. Would I be able to put a charge on the house to do this?
