After 55 years of marriage, my mum has announced that she was a divorce. My dad doesn't want to accept it. I am not sure what to do with them. They both has illness and probably wouldn't survive well by themselves. But if they stay together then the depression and anxiety will trigger my dad to have another stroke and doesn't help my mother's mental illness. The house is in my dad's name and he is worried financially how to survive. Should I point them in the direction of mediation or straight to a solicitor???
