Separating but not married

[Happygoeslucky]

My partner of 15 years has decided to move with her new girlfriend who he has been seeing for more than a year! Trying to cope with the emotional part of it while dealing with the practicalities.

We have 2 kids, 3 and 6. We both work FT, but there is about 100k difference between our salaries. We are both from abroad, but I know moving home is not an option as he is a committed dad. However, staying in London means I can hardly be able to afford renting a flat on my own, let alone a nice place to keep the kids.

He insists he wants 50/50 split with the kids, and he would not need to pay for maintenance that way. He cannot be there for pick up and drop, etc, but his new girlfriend will reduce her hours to do that.

We own the house jointly and there is about 400 K equity on it. I may be made redundant from my current job iN 2 months.

He proposes paying some lump sum to me and 750 per month, which if I loose my job won't pay for a shack! But I want to take care of the kids more and reduce my hours. Am I being unreasonable and should I let this woman share the child care?

And most importantly! HAS ANYONE ADVICE ABOUT SEPARATION WITHOUT BEING MARRIED? What are my chances of him helping me out with maintenance for the kids?

As i understand. If you are the main carer, ie you buy clothes, cut mails etc then you can still claim some maintenance.
I wouldn't be happy about the other woman doing something you can do but i don't know.the legal issues with that

You should see a solicitor as soon as you can. People circumstances are so individual.
I'm sorry for the emotional side, of his affair.

I don't understand your post... he doesn't want to pay maintenance (50/50 kids), but he's suggesting £750 a month? So that is maintenance?

Tbh, he's totally untrustworthy - the cheating. So definitely see a solicitor but I'd push for something that was as upfront as possible. Even child maintenance (above CSA level) can be changed a year after it's been signed up to. I wouldn't rely on him paying that £750.

My advice would be to get all your equity share from the house, ASAP.

Also, now is not the time - IMO - to be looking to cut your hours. Use the fact that you're no longer having to do all school runs to be able to apply more widely for jobs (if you get made redundant).

He doesn't want to pay maintenance. What he proposes is to pay a smaller lump sum than half of the flat and go for a monthly payment to help me until kids move on. It is no maintenance, it is a deferred payment of wht is mine.
Not acceptable.
