I have been married for 6 years have 3 young children (10,7,3) marriage has broken down and we both want to split. I am higher earner and always have been and have paid all house hold bills since moving into our home 10 years ago. I also put a £20k deposit down on the house. House is in joint names. My wife has a good job working only part time (£45k salary gross) looking now to go full time. We initially agreed I give her 50% of the equity in the house after having it valued - which would give her £80k. I was aiming to stay in the family home as always paid the bills etc and she could not afford to cover all the bills on her own. I was also willing to take on all the current joint debts we have of £25k.
We have agreed to have children a full 50/50 split as I am very flexible with work and have always dropped kids off at school 2-3 days a week and picked them up, never missed a school performance etc.
We have been split for 5 months but still living in the family home, I am still paying all bills (mortgage, utilities, car insurance, loans, credit cards etc) we also both each put £700 (£1400 total) into joint account to cover food etc for the month then we are both left with similar money each for ourselves per month.
My wife now wants to stay in the family home but wants me to stay named on the mortgage as she would not be able to get a mortgage on her own for that amount. She thinks she is entitled to more than 50% and also wants child maintenance even though we have agreed on a 50/50 child care split. I feel that she is being unreasonable as my offer to take on all depts and give her 50% equity in the house is more than fair. If we were to go down solicitor route and back and forth sell house split all debt etc I believe she would only end up with around £35-$40k as we both would which would be sufficient for me to start again if thats the case, I just feel she is trying to get more when infact its going to cost her more in doing so, or am I completely wrong in my thinking?
