You say you live in Northern Ireland.The law there may not be the same as
it is in England and Wales.
In E & W the starting point is :
1.
He would have to pay 15% of his net salary to support your dependent child,
This is subject to variation according to how many nights your 13 year old
stays with him overnight.
2. It is likely he could have to pay a
further sum on top of that by way of spousal maintenance ( SM ). SM
depends on your needs and his ability to meet or contribute to them.
3. There is a house free of mortgage. I find it difficult to advise on
housing without knowing more of the local situation. On the face of it,
there may be enough to re-house you both. Another idea which I sometimes
suggest to people on low incomes is part buy, part rent, where you pay a
reduced share of the purchase price and pay rent on the balance. In low
income cases housing benefit may be available on the rental element of the
payments. However, making sure you both have somewhere to live is a high
priority for the Court.
4. You would almost certainly have a claim to
a pension split. If SM were awarded it might terminate when the split takes
effect.
5. This is a long marriage and the norm would be a settlement
somewhere in the region of 50/50.
I don't like to give to give
detailed forecasts like the
divorce calculator, at least not at this stage. The
first requirement is making sure you both have enough to live on. How much
is left after that has been taken care of does rather depend on your
individual circumstances.
