Father's Failure to Make a Will Plunges His Widow Into Legal Difficulties
One of the best things you can do for your loved ones is to sign a professionally drafted will. As a High Court case showed, failing to take that easy and cost-effective step is to risk plunging those closest to you into legal difficulties after you are gone. The case concerned a German national who died intestate. Under German law, his widow was entitled to half his estate with the remainder being shared between his five children equally. As a result, his youngest son, aged 16, inherited a one-tenth share in a German property and two garages that were owned by his father. Following the father's death, mother and son settled permanently in England.
