From HM Revenue & Customs · Child Benefit Technical Manual

A failure to disclose a material fact arises
where a change of circumstances occurs between written statements of circumstances, for example claim forms or statements made on case checks, and the change is not reported
or
where a written statement is inaccurate or incomplete.
A failure to disclose may be more difficult to establish than a misrepresentation depending on the circumstances of the case.
