These Regulations make a consequential amendment to Schedule 1 to the Child Support Act 1991 (c. 48) (“the 1991 Act”) arising from the increase to the flat rate of child support maintenance from £5 to £7 for cases in which liability for child support maintenance is calculated under Part 1 of Schedule 1 to the 1991 Act as amended by paragraph 2 of Schedule 4 to the Child Maintenance and Other Payments Act 2008 (c. 6) (the “2012 scheme rules”). The flat rate of child support maintenance was increased from £5 to £7 by paragraph 4 of Schedule 4 and paragraph 1(28) of Schedule 7 to the Child Maintenance and Other Payments Act 2008for cases subject to the 2012 scheme rules. These Regulations also make other consequential amendments to certain secondary legislation as a result of the increase to the flat rate for those cases and make miscellaneous amendments to the Child Support Maintenance Calculation Regulations (S.I. 2012/2677) (“the 2012 Regulations”) in relation to the reduced rate of child support maintenance and in relation to variations. The reduced rate of child support maintenance is payable if neither the flat or nil rate applies and the non-resident parent has income of less than £200 but more than £100. Variations allow for deviations from the usual rules for calculating maintenance in certain limited circumstances.
