What? Sleep with half of England? Unfaithful women are everywhere, England included.
As for maintenance (alimony) payments, a decision as to how much should be paid depends on the needs of the children and the wife.
It's usual for an absent father to pay maintenance until his children finish education. How much he pays depends on his income and outgoings.
As regards custody, that is usually given to the mother,with the father having access rights, though if there are no objections, joint custody is perfectly normal.
In making these decisions, the welfare of the children is important, not whether the soon to be ex-wife is a complete slapper!
Marriage is, in short, the real everyday story of male liability at all costs and in nearly all situations.
All i know about Polish family courts, is the horror stories i've read on here. I would like to think that judges have the best interests of the children at heart, but as in the UK, no system is perfect. Generally, it appears as if the mother has the better deal, but mostly it will be her looking after the children, and possibly unable to work herself. Don't make light of how hard it is to be a mum.
Incidentally, i never received a single penny in child support from my son's father. He was determined he wouldn't pay, and he got away with it.
