Wales, United Kingdom. Want to make sure my mother can't tie me to anything

Very abusive tumultuous childhood. I've recently gone no contact with my mother.

She's always threatened to tie her children down in the will (5 children, 4 hate her, and want nothing to do with any issues after her death). She's had leakeamia before, she's 57 now, so who knows when she'll die.

She "runs" an equine business (runs is in quotation marks because she's at least 10k in debt to her suppliers). I'm basically the only child who would have the knowledge to run the place after her demise.

Shes always threatened that she'll put "clauses" in the will so we can't sell her horses or land after she dies. She's absolutely awful at finances, thinks Facebook messages count as a contract between her and her equine clients. I've always assumed her threats are absolute drivel.

But I thought I'd check anyway, is there anyway she can tie children down like this when she dies? She has massive issues with the planning department, just built whatever she wanted without any applications, and she's a very unlawful person in general.

I want absolutely nothing to do with anything, I will happily relinquish any monetary value to make sure of this, in case there's a way for her to try doing the "you can only get this money if you do such and such" (again, I know nothing, don't know if this is possible, just want to give as much info as possible)

Any advice is much appreciated.
