Claimant Compliance Manual

Examinations: Information: Specifying the dates for receipt of information requested

You should always tell the claimant(s) the date by which you expect them to have sent the details requested. You should use your judgement in deciding how much time to allow, taking into account the nature and volume of the information; but the period should never be shorter than 30 days. Always be specific: don’t ask for information “within 30 days”, but say “by 31/8/2009; by 15/10/2009, etc.” This way claimants will be left in no doubt, and you will be better able to track the progress of the case.
