The 4 sons of our mother inherited the family home upon her death. 2 of the sons (my brothers) bought my brother and I for half the lowest valuation we got from a number of agents. My brothers and the wife of one (the other was single) inhabited the house with the brothers being tenants in common with one half share each. The married brother died and his wife (our sister-in-law) inherited his half of the house. They each made a will leaving their share to the other. 5 weeks prior to her death of bowel cancer, she changed her will, (with the same solicitor) leaving her share to her 2 children as their inheritance (our nephew and niece). My brother was not told of the change at the time. As tenants in common, I realize that he does not have to sell his share of the property and he can stay there till he dies, but the niece and nephew both have their own homes and we are concerned that they could make things awkward, if for example, they wanted to let part of the house to their children or strangers. I understand that they themselves have free access, but can they approve any person to live within the property?
