To ask about this - relationship breakdown/housing

[Yellowcakestand]

Sorry, I can't find where to put this query and someone here is bound to know.

A parent leaves the family home (owned). Other parent wants to stay in the family home. Who is responsible for paying what? How does it work?

Nobody can answer or even guess with so little information. Married? Children? Who is earning what?

It’s complicated which is why people use solicitors unless they can agree between themselves.

Sorry.
Yes married.
Yes children.

How do you expect anyone to even start to address your question with so little info OP?

Go and see a solicitor.

Who is responsible for paying what?

What sort of what?

Owned as in mortgage free?
Are the dc going to be spending 50% of their time with each parent?
How much do each of the parents earn?

It depends entirely on the circumstances of the family.

Is there a mortgage? Are they renting? Do they both work?

But generally, the one remaining in the home becomes responsible for all the bills, and has to get maintenance from the absent parent to help with the costs.

House owned or rented? In one name or joint?

Sorry, just seen that the home is owned. Is it owned outright?

Generally in the interim both are jointly responsible for the mortgage on the same basis as before the split but the person in the house will pay the other bills, the person wishing to stay for the long term would need to be able to buy out the ex partners share (though it could be property in lieu of pension for instance). There's so many variables though, not everyone can afford mortgage and rent for starters. A semi amicable arrangement is usually better than a solicitor for interim agreements, we aren't using a solicitor at all for our divorce in fact.
