Long story short: High conflict divorce

4 Mediation sessions: agreed to 60/40 to her favor for Child arrangement (no formal documentation yet)

Currently weekly custody-50/50. As she is being too demanding for financial settlement (absolutely being greedy), I am wondering if I should fight for child arrangement to retain the equal shared custody that we have today.

Want to get feedback from men (in the UK) on the likelihood of getting the same. No safeguarding concerns but the mother will allege anything and everything and will go to any extent to portray things otherwise.

Is it worth the cost and process to fight for the 10% which am theoretically letting go as part of mediation? I will probably have to fight for financial settlement in court, and thinking I should do the same for my kid.

Please provide your experience on the court proceedings and the cost you incurred for financial settlement and child arrangement orders.
