DH (married 15 years) wrote his will before we met, leaving everything to his adult daughter. He did not own any property at the time. We now jointly own a house and are looking to pay off the mortgage soon. He has not updated his will but says legally I will be entitled to half of our joint assets, despite what his will states. Is this true? I don't have any issues with his daughter inheriting his share but I would feel more comfortable if it was formalised so everyone knows where they stand. Can anyone provide any advice on this please?
