Change of circumstances
Can child maintenance be recalculated if your income changes?
An assessment of child maintenance remains in place for 12 months unless income has increased or decreased by at least 25%. If your income change is 25% or more, request a revision or supersession. Lesser changes will be included in the annual recalculation.
Other changes such as an increase in the number of nights that a child stays with you above the 52, 104 or 156 night thresholds in the past year, becoming responsible for a child in a new family or a 16-19 year old child leaving full-time, non-advanced education will reduce maintenance liability.
