UK domestic partner squatting

Question

A couple have been together for a few decades.

One of them sold their house 10+ years ago when they hit hard times, since recovered from.

About 8 years ago the other inherited a house on their parents' death.

They are now living there with the non-owner paying no rent.

If the owner should die in future, could the non-owner claim some sort of squatter's rights and own the house?

Answer 1

No

But they can make a claim under the Inheritance (Provision for Family and Dependants) Act 1975 if the deceased partner’s will makes inadequate provision for them or if there is no will.
