How Child Maintenance is Calculated (2026 Statutory Rules)

Under UK statutory law, consumers and claimants possess defined statutory rights that cannot be contracted out or overridden by company terms and conditions.

1. The Legal Framework

Key governing authority: Child Support Act 1991; Child Support Maintenance Calculation Regulations 2012.

Parties are legally required to adhere to Pre-Action Conduct principles before issuing court or tribunal proceedings. Failure to follow the prescribed statutory process can render notices invalid or lead to severe costs penalties.

2. Key Statutory Tests & Time Limits

Strict time limits apply across England and Wales. Ensure that you have recorded exact dates of notices, service receipts, and written communications.

3. Evidential Burden

The standard of proof is the balance of probabilities (civil standard). Clear contemporaneous logs, photographs, correspondence trails, and proof of postage form the cornerstone of any successful challenge.
