Do I need to pay half my husbands rent since we separated?

My husband left 9 years ago and agreed verbally to let me stay in family home until girls were 18.
My youngest is 18 next year and he has now requested 50/50 split . I have asked for 60/40 as I earn less than £15k a year self employment and can’t raise much mortgage . He is saying that I will have to pay half his rent that he’s paid out over the years . I had hoped to have an agreeable divorce and was willing to forgo other assests if I got 60% of house. But is he right that I might have to take his rent into accounts?

No, but on the other hand you have been living in a house half owned by him for the last 9 years so he may have a claim for an occupation rent. I should say that such claims are rare and it is by no means certain he could make a successful claim. Much would depend upon other factors such as what level of support he has provided for you and the children over that time.

I would take that sort of claim with a pinch of salt. How the equity really gets divided will depend upon factors such as the size of the equity and your respective housing needs and resources. It is very unlikely that rent of any sort has anything to do with it.

I’m not sure if he’s just trying to scare me into a online divorce or whether he’s got a solicitor that’s filling his head with things . I’ve never heard of anyone having to pay the exes rent but we have waited a long time ... as many do with young children. He also has chosen to live in town centres where rents are generally higher ... just want to be aware of what is likely to be taken on board .
I certainly can’t afford much of a mortgage after raising my daughters I’m only rebuilding my business.
Just want a fair share

People often say all sorts of things but that doesn't mean they are true. There is absolutely no prospect of you having to pay something towards your husband's rent. That is so nonsensical that I am 99.99% sure that is coming from him rather than from any solicitor.
