If, by virtue of Articles 9 and 15 (3) of the Regulation, a person satisfies the conditions for admission to a voluntary or optional continued insurance in respect of invalidity, old age and death (pensions) in several schemes under the legislation of one Member State, and if he has not been subject to compulsory insurance under one of those schemes by virtue of his last employment or self-employment he may, under the said Articles, join the voluntary or optional continued insurance scheme specified by the legislation of that Member State or, failing that, the scheme of his choice.

In order to invoke the provisions of Article 9 (2) of the Regulation, a person shall submit to the institution of the Member State in question a certified statement relating to the insurance periods or periods of residence completed under the legislation of any other Member State. Such certified statement shall be issued, at the request of the person concerned, by the institution or institutions who administer the legislation under which he has completed those periods.
