How Long Should A UK Child Maintenance Agreement Last?

A child maintenance agreement should state both when payments start and exactly when they end or are reviewed. The clearest options are usually a fixed end date, a specified age, or an education-linked trigger. Vague wording such as until further notice can create uncertainty and disputes.

What End Point Is Most Common For Child Maintenance?

Many private arrangements track the statutory child maintenance position: maintenance is commonly linked to a child being under 16, or under 20 if they remain in approved education or training. If using this approach, define the education requirement and include a duty to share school, college or benefit-related updates.

When Should A Child Maintenance Agreement Be Reviewed?

  • Annual reviews suit most rolling or statutory-linked arrangements, especially where income changes are likely.
  • Termly reviews are useful where payments depend on boarding school, college, university preparation, travel, or other education costs.
  • Review before an end date is important for fixed-term agreements, so parents can renegotiate before payments stop.
  • Immediate review triggers should cover changes in income, care pattern, benefit entitlement, a child leaving education, or a new CMS calculation.

Why Is Precise Wording Important?

End-date wording is especially important where the agreement ends when a child reaches an age, leaves full-time education, or where the arrangement is intended to follow the Child Maintenance Service position. The agreement should say whether payments stop on a birthday, at the end of a school term, at the end of an academic year, or after written confirmation of the relevant event.
