Yes, being on maternity leave does not normally prevent you from claiming Child Benefit if you are responsible for a qualifying child. Child Benefit is separate from Statutory Maternity Pay or Maternity Allowance, so these payments do not usually stop your claim. However, a High Income Child Benefit Charge may apply if you or your partner has income above the relevant threshold. You can check the rules and apply through the official GOV.UK Child Benefit page; claiming may also provide National Insurance credits while your child is under 12.
