Field help:
Has the other parent fulfilled less than 75% of his or her maintenance obligation?
Select "yes" if the other parent has fulfilled less than 75% of his or her maintenance obligation towards the child.
Then you can claim (without the consent of the other parent) the full child allowance and the full care allowance. The other parent does not receive any allowance for this child.
If full allowances are applied for, both the full child benefit claim and the full child allowances are taken into account in the tax return.
