The logic by some on here of “he was their person first/longer” absolutely baffles me.
When a child dies before a parent, the parent will always have been in the deceased’s life longer than the will spouse have…. But in the UK, the spouse trumps all other relationships, as it should.
When he made the choice to marry OP, he knowingly and legally superseded any relationship before, including the one he shared with his parents. By getting married he chose OP to be his new immediate family and enshrined that in Law. By getting married he overturned any Will that he may have had drawn up beforehand.
By getting married, he chose OP, the person he must have trusted the most to have his best interests at heart, to be the one to make any decision on behalf of himself and his estate…. should he be unable to.
If he didn’t want OP to act as a spouse with all the legal responsibilities and expectations that it entails then he wouldn’t have married her, she would have been a girlfriend… but never a spouse. His age and the length of the marriage are inconsequential to the legally binding role of a spouse.
Those were his wishes. Why should his wishes not matter now or not be honoured?
OP, I am only in my 30’s, only been married a few years…. But if god-forbid anything happened to my husband even now, it would be a cold day in hell before I let anyone go against my dead husband’s wishes.
Your husband entrusted you to act for his best interests. Do what you will.
