In order to determine the entitlement to benefits and legitimacy of payments under the Slovak or Netherlands' legislation, a beneficiary or a member of his family shall identify himself to the competent institution in whose territory this person resides or stays, by submitting an official proof of identity. An official proof of identity includes a passport or any other valid proof of identity issued by the agency in whose territory that person resides or stays. The competent institution identifies the beneficiary or the member of his family on the basis of this identification. The competent institution concerned shall inform the competent institution of the other Contracting Party that the identity of the beneficiary or the member of his family has been verified by sending a copy of the identification document.
