Thank you for confirming. Firstly, as they are married she has matrimonial home rights, which mean she has a right to live in the property until divorce.
If he were to pass away and he does not have a will, she will inherit the property and any other assets that he has solely as there are no children.
If he does have a will and he has not provided for her in the will, then she can make an application to court for reasonable provision from his estate due to her needs and residing in the property which was the matrimonial home.
Given that her name is ***** ***** the property, she can register her matrimonial home rights on the title of the property using Land Registry form HR1 - her husband will be notified of this registration. Her name will appear on the title of the property to show she has an interest in the property.
If she were to decide to proceed with a divorce, then this property and all their other assets (whether held jointly or solely) will form part of consideration to settle their finances.
