DP is in the throes of formally drawing up a financial order with his ex wife. They have 2 DC aged 10 and 12. He and I met 1 year after their separation. Post separation they have had an informal arrangement whereby DP gives her 50% of his salary every month and a share of bonuses (he is a high earner).
Ex wife is not agreeable to formalising the current arrangements and claims that since DP and I now live together she would like 50% of our joint household income for her and the kids. I received a letter yesterday summoning me to court and have been asked to provide a full financial disclosure.
My question is what are my legal rights with this? Does the court assign CM and SM based on joint household income? Also, do I have to provide a full disclosure of my salary/assets to the court? DP and I contribute jointly to mortgage/bills/food, but otherwise keep our finances separate.
