There is GIRO arrangement that can make auto-transfers every mth
which he can set up by approaching his bank, I believe. But I
wonder why he does not just fight for custody of his kids if he is
'maintaining' them. I know for a fact that women's "alimony" after
marriage is determined by how much time is given to the mom.
If the father has equal custody or full custody, he hardly has
to give a cent. If the father is already paying maintenance for his
children, he may as well apply for full custody.
Unless he committed adultery and the ex wife can prove it, there
is a high chance for the father to be given custody if he is
already financially supporting the kids.
