Hi My husband inherited a property in Spain from his mother, both are french, his mother left the property to both himself and his sister in equal parts and the use of the property to her partner at the time they were not married. They are no longer liable for tax as she died more than 5 years ago. but his sister is refusing to validate the will and the property is falling into disrepair as neither she or his mothers partner have the funds to pay the yealry taxes or the upkeep of the house and is is empty, we have paid some monies for work that needs to be done and local taxes. Can we force his sister to sign the will, or what will happen to the property as no one has lived in it since his mother died.
many thanks
