Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, how many people who have child maintenance arrangements with the Child Support Agency have received letters on the termination of those arrangements with the Child Support Agency.

Letters are issued when the liability on a case has ended. We have interpreted this question as the number of people who have been sent letters after they have had their liability ended.

The total number of cases where liability has ended stood at 509,200 as of the end of September 2016.

This can be found in Table 4.1 and 4.2 of the Case Closure Experimental Statistical publication which can be found here https://www.gov.uk/government/statistics/child-support-agency-case-closures-june-2014-to-september-2016.
