My sister who is 74 has owned her own home for years ,she married a man around six years ago and she sold her house and bought another one with the proceeds, the marriage is now failing and she is concerned that he might have a claim on her estate .she has made a will and bequeathed the property to a third party ,allowing her now husband to live there until death as long as he maintains the property and pays the bills.my question is in the event of her death would he have a financial claim on the house
