In order to receive benefits under Articles 37, 38 and 39 of the Regulation, including the cases referred to in Articles 40 (2), 41 (1) and 42 (2) of the Regulation, an employed or self-employed person shall submit a claim either to the institution of the Member State to whose legislation he was subject at the time of occurrence of the incapacity for work followed by invalidity or the aggravation of such invalidity, or to the institution of the place of residence, which shall then forward the claim to the first institution, indicating the date on which it was submitted; this date shall be regarded as the date of the submission of the claim to the first institution. However, if sickness insurance cash benefits have been granted, the date on which such cash benefits ceased to be granted must, where appropriate, be regarded as the date of submission of the pension claim.

In the case referred to in Article 41 (1) (b) of the Regulation, the institution with which the employed or self-employed person was last insured shall notify the amount and the operative date of the benefits due under the legislation which it administers to the institution initially responsible for payment of the benefits. With effect from that date, the benefits due prior to the aggravation of the invalidity shall be cancelled or reduced to an amount not exceeding the supplement referred to in Article 41 (1) of the Regulation.

The provisions of paragraph 2 shall not apply in the case referred to in Article 41 (1) (d) of the Regulation. In this case, the institution with which the claimant was last insured shall apply to the Netherlands institution in order to ascertain the amount due from that institution.
