Theoretical question here on the terms of a will, specifically re: a clause attached to a right of residency to one child (of 4), barring that child from moving their partner in after the remaining living parent passes away. What criteria would you use to consider if someone had been moved in/'living' in the deceased's property?
I've possibly made it overly complicated/convoluted above.. in other words, a father's will leaves the family home to all 4 children, with right to continue living there granted to one sibling, with the condition they never move their partner in.
