The UK Child Maintenance Service statutory assessment framework is intentionally restricted by a statutory income cap. Under Paragraph 10(3) of Schedule 1 to the Child Support Act 1991, the maximum gross assessable earnings considered by the CMS are £3,000 per week, equivalent to £156,000 per year.

For executive, partner, or entrepreneurial parents earning in excess of £156,000, statutory CMS jurisdiction ceases on all earnings above this threshold.

Maximum CMS Statutory Assessments

Regardless of whether a paying parent earns £200,000 or £2,000,000 annually, the CMS calculation remains capped at the following statutory maximums (prior to shared care deductions):

  • 1 Qualifying Child: Maximum £294.00 per week (£15,288 / year).
  • 2 Qualifying Children: Maximum £392.00 per week (£20,384 / year).
  • 3+ Qualifying Children: Maximum £482.00 per week (£25,064 / year).

Applying for Court Top-Up Orders (Schedule 1 Children Act 1989)

Where a paying parent's income substantially exceeds the statutory cap, the receiving parent is legally entitled to apply to the Family Court for a Top-Up Order under Section 8(6) of the Child Support Act 1991.

Mandatory Pre-Condition: A Maximum CMS Assessment Must Be in Force

Under established family law precedent (Dickson v Rennie [2014] EWHC 4306 (Fam)), the Family Court has no statutory jurisdiction to make a top-up maintenance order until a formal CMS assessment at the maximum £156k cap is formally in place. Attempting to bypass the CMS and initiate court proceedings directly will result in the application being struck out for lack of jurisdiction.

Judicial Discretion and Wealth Considerations

Once the £156k gateway is satisfied, the Family Court exercises broad judicial discretion under Schedule 1 of the Children Act 1989. Key factors considered include:

  • The standard of living enjoyed by the family prior to separation.
  • School fees, extracurricular coaching, and private medical insurance costs.
  • Housing requirements for both parent and child (re P (Child: Financial Provision) [2003] 2 FLR 865).
  • The paying parent's total capital, business shares, and worldwide assets.

High-earning parents are strongly advised to seek specialist family law advice to negotiate an agreed top-up consent order rather than incurring catastrophic litigation costs in the High Court.
