I see you have not had a reply, so I will try.
The overall objective the Court will be to make sure both of the soon be ex spouses will have somewhere to live. Ideally, that somewhere
should be such that the children can stay with their parent on a regular basis.
So if the
FMH can be sold and you both have incomes large enough to support a mortgage, that is normally to be preferred as it leaves both spouses untrammelled by the mortgage on the FMH and can make a fresh start. In a depressingly high number of the cases we see, the husband can't get a mortgage because he is already committed to ehe existing one on the FMH - and therefore he has little alternative but to rent.
You have to pay child support and here you don't have to guess because the amount is fixed by reference to the statutory formula.
Whatever you have to pay is a first charge on your income. You must always be left with enough to secure accommodation and pay for it. As I said, if the property is sold and both of you can make a fresh start.
I'd expect a slight adjustment to the pensions.
But your case seems on the face of it comparatively easy , as divorce settlements go. Shen resources are scarce, it is frequently necessary to have resources to benefits, and even if your case it's
a factor. Sometimes, regrettably, divorce settlements are akin to
putting quarts into pint pots.
Hope this is of some help.
