Certificates and information to be submitted with the claim by the claimant

1.   The claim shall be submitted by the claimant in accordance with the provisions of the legislation applied by the institution referred to in Article 45(1) or (4) of the implementing Regulation and be accompanied by the supporting documents required by that legislation. In particular, the claimant shall supply all available relevant information and supporting documents relating to periods of insurance (institutions, identification numbers), employment (employers) or self-employment (nature and place of activity) and residence (addresses) which may have been completed under other legislation, as well as the length of those periods.
2.   Where, in accordance with Article 50(1) of the basic Regulation, the claimant requests deferment of the award of old-age benefits under the legislation of one or more Member States, he shall state that in his claim and specify under which legislation the deferment is requested. In order to enable the claimant to exercise that right, the institutions concerned shall, upon the request of the claimant, notify him of all the information available to them so that he can assess the consequences of concurrent or successive awards of benefits which he might claim.
3.   Should the claimant withdraw a claim for benefits provided for under the legislation of a particular Member State, that withdrawal shall not be considered as a concurrent withdrawal of claims for benefits under the legislation of other Member States.
