You'll be paying for years and years and years, Tiger, if you take this thing to court and - for goodness sake - think about hiring a QC. This is madness. Take your £13K and do something useful with it, not throw it into lawyers' bank accounts. Rent a stable place where your ADHD son and the rest of the family can be secure. You're going to get nowhere with this. Like others, I'm growing more and more suspicious of this "solicitor comments" you keep talking about. Who is this person, are you sure he/she is legally qualified?
