Recently my Stepnan passed away.
Several years ago she set up some kind of trust - my DM says she and my DSF are the trustees and my DSF, DB and myself are the beneficiaries.
Split three ways there's about £125k in the trust for me.
However DM says that she's been told that the terms of the trust mean it can only be spent on property, and that it must purchase a whole property (I.e. I can't pay a chunk off my mortgage).
She also says that the property would be owned by the trust, not by me, so any rental income or similar would belong to the trust.
My DB lives in Stoke so the plan is for the trust to purchase a home for him and his partner to live in rent/mortgage free for the rest of their lives (albeit that they don't own it as the trust owns it).
I live in Hampshire, you can't buy anything here for that money so effectively my £125k is completely useless to me which seems weird 
My stepfather is quite controlling and I have this feeling that what I'm being told isn't actually correct.
The motivation I believe is to keep the assets untouchable by my DH if we divorced (and DB's partner if they married and then divorced). I don't agree with this approach at all - I don't agree with the principle and it means I won't benefit at all from my inheritance.
Any ideas if this can be correct - I've done some simple online research and I can't see why the trustees wouldn't be able to vary the terms of the trust.
Why would anyone set up a trust for inheritance that makes it impossible for the beneficiary to use the money?
