My mum and step-dad are divorcing at 60. They've been married for 23 years and had their ups and downs due to my step-dads drinking which has got progressively worse over the years (reason for my mum filing for divorce). Both were previously divorced and my mum had a house on her name before she got married to which my step-dad moved into (he had nothing other than £5,000 in cash). She remortgaged her house to buy our new family home. Any money that came from her house was put into the new home, my mum paid for all home renovations/ expenses/bills and shopping minus the mortgage. When she sold her home she put that money into the family home, our education, our weddings and holidays.
My mum wants nothing from my step-dad other than a 60/40 split after they sell the house to which my dad isn't agreeing. My mum thinks she deserves more out of the house as she put money from her home into their joint home, other than mortgage and a few holidays he has contributed nothing over the last 23 years - they both have worked all their lives. He has a really good pension pot, land and a few properties in his native country, his mum has just passed away too and we know she is leaving him an inheritance all of which my mum has not benefited from. My mum has an ok pension, some savings and some gold.
My dad is now refusing to sign the divorce papers unless my mum signs papers stating she is happy with a 55/45 split (in her favour) but also confirming she wont take him to court or fight for anything else. My mum doesn't want to go to court at all but she does feel like she is being used and hard done by and the change in my dads behaviour (panic but with a little arrogance) is making her question everything. I am biased because she's my mum but she is a moral person, in her first divorce with 2 kids, she paid my paternal dad out, fought for full custody and refused child support. She doesn't want anything of his other than her share of the house.
She's considering financial mediation upon the suggestion from her solicitor (to which we think he won't go a long with) but we're not sure what to do. He is convinced that if she takes him to court its 50/50. Anyone else been through a similar experience? What are the chances of this going in her favour? Is she going to fight a losing battle?
