Aim for a clean break. I have just gone through this in NI. As an I dictation to our similar stories.....We couldn't afford childcare and I had to step back from my career to care for our children. I couldn't afford not to work either so became self employed with a modest wage guaranteeing that we had no childcare costs. All my earnings went back into the family/home, couldn't afford to pay into a pension. Should have prioritised it, but the family home and husband's pension were to fund our retirement. He pursued and advanced in his career and like your wife, my focus which we agreed upon, was the family and home.
Fast forward, divorce on the cards. As the more vulnerable in the partnership I was afraid of the change for myself and the children both emotionally and financially. But long story short, the similarities here would make me believe you could come to a similar arrangement.
Agree the family home is to be sold, mortgage cleared and split at a rate of usually 70/30 or 65/35 after conveyancing fees. You both pay your legal bills from your equity share.
You can then trade off some of your equity for a spousal maintenance lump sum.this happened in my case. You may trade off more in lieu of other assets you have. This would allow your wife to maximise her cash deposit for the purchase of a new house.
Your pension then would be open to being shared at anything from a starting point of 50/50 and can be transferred into a pension of your wife's choice.
Then contact child maintenance service and find out what rate you are expected to pay. You can then determine if you would like to and are in a position to pay more. Agree with your wife in principal things like how school trips payment will be shared between you. Driving lessons, tuition, school uniforms etc etc etc
You are correct that a clean break would be best. Ideally where some dignity can be shown on both sides for the sake of the children and the past that you shared, the future you had hoped for and the future ahead where you will still be tethered to one another as a consequence of having children together. I am not going to say this will be easy or will happen. I wish it were the case for me but divorce can bring out a really destructive and petty side in people.
Don't be taken advantage of. You need to be able to afford a home too where your children can stay with you. Your wife and kids will have to downsize or relocate to somewhere that homes are cheaper but the standard of living might be retained. That will be her choice.
Your wife might not be able to get a mortgage. I wasn't able to 1. because of being self employed with 2.the income that I had. a relative took out a joint borrower sole owner mortgage with me. She's liable if I default but I am able to cover my mortgage. Your wife might need a relative to step up for her here
You sound like a decent person from what you have written so irrespective of how your marriage has reached where it is
- Your wife will be afraid
- She needs time to build up financial and emotional security.
If you continue to be considerate but with the guidance of a solicitor you would be best opting for a clean break, selling the house, splitting it appropriately, pay a spousal maintenance lump sum (she won't be taxed on it if it's a lump sum given at sale of house), agree a split of pension and other assets or trade off by giving her all of certain. Pensions to that she relinquishes all right to further monies.
You can review child maintenance annually as your wages increase. You can start with the minimum recommended and then create a private arrangement,document what additional you're willing to pay for.
I would say definitely get a good solicitor that comes recommended. You can instruct them to be gentle or to be pushy with the opposing legal team. It might be difficult to be kind and dignified when negotiating these next stages but you love your kids so it's important to treat their mother well. It doesn't mean giving in to all her demands, it's just means being fair.
Best of luck
