How is the amount of Child Maintenance worked out?
The Agency take into account:
the day to day cost of maintaining a child;
the income of the parent with care and the Non-Resident parent after making allowance for tax, national insurance, half of any pension and basic living expenses, including rent or mortgage costs. The income of the parent with care can serve to reduce the Non-Resident parent's payments but in most cases is not high enough to do so;
any other children either parent may have.
New partners of either parent will not be expected to pay anything towards the child support maintenance of children who are not their own.
However, partner income details are required because: Where the parent with care and their current partner or the Non-Resident parent and their current partner have a child(ren) of their relationship it needs to be established if the partner can contribute to the upkeep of that child(ren).
In the case of a Non-Resident parent, information is required to check that the income of the Non-Resident parent's household does not fall below certain limits if the maintenance liability was met in full.
A formula is used to work out how much child maintenance is payable. It takes account of each parent's income and essential outgoings.
