CCM12100 - Opening and Working Enquiries: Enquiry notice - general

You must give notice of your enquiry to the person, or each of the persons, into whose entitlement, or joint entitlement, you are enquiring. If the claim was made by a couple, you must give a notice of enquiry to each. You cannot choose to issue an enquiry notice to only one member of the couple, even if you feel certain that all the information you need for your enquiry relates to that person (for example, if you are enquiring into that person’s income). If you do not give notice to both persons where there is joint entitlement, your enquiry will not be valid and you will only be able to correct this and open one if you are still within the normal time limit (the enquiry window).

The guidance at CCM12130 tells you what to include in the notice of your enquiry but you must ensure the notice is valid otherwise you will have to cease your enquiries – see CCM12110- 12125
