Child support: how it is decided and what to do when it is not paid

Child support is the child's right rather than a payment between parents, which is why it cannot be waived in a private deal and why arrangements are examined rather than simply approved. Amounts turn on the child's needs, both parents' means, and how care is actually divided.

What it covers and how it is approached

Support is meant to cover the child's real costs: housing share, food, clothing, health, education and the extras that come with them. Beyond basic needs, both parents' income and earning capacity are relevant, as is the real division of care time, which has become increasingly significant. Because these turn on facts rather than formulas, an honest picture of the child's actual expenses is the most useful thing you can prepare.

Agreements need approval to be worth anything

A private arrangement between parents does not bind the child. Have any agreement approved so that it becomes enforceable, and set out clearly what is included, what is shared, and how extraordinary expenses such as medical or educational costs are divided. Vague wording about splitting extras is the single most common source of later conflict, so name the categories and the mechanism.

When payments stop

An approved order can be enforced, including through the Enforcement Authority, and there is a route through National Insurance for certain cases where support is not being paid. Do not let arrears accumulate silently while you wait for things to improve. Keep the record of what was due and what arrived, since enforcement works from that comparison. If circumstances genuinely change on either side, the route is to apply to vary the order rather than to stop paying and explain later.

FAQ

We agreed an amount between ourselves.
Get it approved. An unapproved agreement is difficult to enforce and does not prevent a claim being brought on the child's behalf later.
I lost my job. Can I stop paying?
Stopping unilaterally creates arrears and enforcement. The route is to apply to vary the amount, and applying early is treated very differently from explaining afterwards.
Do shared custody arrangements reduce it?
The real division of care is a relevant factor, though it does not work as a simple discount. What matters is how the time and the costs actually fall.
The other parent has disappeared.
There are enforcement routes and, in defined cases, a National Insurance route. Start the formal process rather than waiting, because arrears are easier to pursue than to reconstruct.
