Where an unsigned claim form is received, a Delegate should register the claim and take a photocopy for file, but then return the original claim form to the claimant with a covering letter asking for the claim form to be signed and returned without delay.

The Delegate may in the interim begin what limited investigation of factual and medical circumstances is covered by documents accompanying the claim form.

However, the Delegate should progress the matter no further, and especially should refrain from approaching agencies and medical personnel for further information until the claim form is returned with the claimant's authority to proceed.
