Maintenance payments/ finances after split.

[Mightyjungle]

When we finally separate, custody of our 2 DCs will be roughly a 4:3 split, me maybe having custody slightly more than this.
My understanding is that he will have to pay maintenance as they will be with me more? Also, I will be the one to buy their clothes etc and will prepare most of their meals so it makes sense that he pays me maintenance.
I have worked out my finances on splitting and my annual salary will be just shy of 30,000 when I return to work on more hours. Based on DHs earnings, he will need to pay £500-£600 in maintenance PM and I'll be entitled to tax credits. It seems I'll be ok financially provided I move into a smaller home than we have currently.

But will DH be entitled to anything? His salary is just shy of 48k, if he pays me £500+ per month, I'm wondering how he'll afford a mortgage of his own on a 3 bedroom house. Will DH be entitled to tax credits etc? Currently, his earnings cover all our outgoings, mortgage, bills, cars, fuel, groceries, kids necessities and my earnings (very low at present due to PT hours) cover anything extra like holidays, swimming lessons, christmas, birthdays.
I'm not sure if he'll have much money left over for himself. Am I right that I'll be better off than him overall?
Do other Dads find maintenace payments crippling?
Am I wrong to be worrying about him and not myself? Is it tight being a single mum despite working a reasonable salary?

Only one parent can claim any benefits in relation to the children and on £48k it is very unlikely to be entitled to any government support.

Tax credits are no more. It is now universal credits. I would go to Turn2us website and get an up to date benefit calculation to see what you are entitled too ( it was accurate for me)

I would also go to the CMS website and do a calculation of what he should pay there. 2 children is 16% of his salary (minus pension but not tax/NI). Then it is reduced depending on the number of over nights.

UC are not generous. Although do cover a good chunk of my child care bill.

And in my situation like many others the children's father promised to support his children I have had 2 payment in 2.5 years. And CMS have been useless.

Are you sure he will pay that much? CMS calculator suggests £350 /month

If he has no pension contributions, then the right figure is about £350 as stated above - reflecting the 3 nights a week he would have them. Reduce if he pays into a pension.
There are cases where men ARE worse off than women following a split, but plenty of cases where women do worse.
