The Social Security (Norway) Order 1991

(1) Where a person insured under the legislation of one Party, and employed by an employer with a place of business in the territory of that Party, is sent by his employer to work in the territory of the other Party, the legislation of the former Party concerning liability for contributions shall continue to apply to him as if he were employed in the territory of the former Party provided that, at the outset, the employment in the territory of the latter Party is not expected to last for more than three years and the person concerned is paid by or on behalf of that employer. No contributions shall be payable in respect of that employment under the legislation of the latter Party provided that a request for a certificate of continuing liability has been received by the authorities of the former Party within the first four months of the period of detachment and presented to the appropriate insurance authorities of the latter Party within two months of its issue. If either one of the latter conditions is not complied with the legislation of the former Party concerning liability for contributions shall cease to apply from the date of commencement of the period of the employment in the territory of the latter Party.

(b) where the provisions of sub-paragraph (a) of this paragraph do not apply and the undertaking has a branch or agency in the territory of one Party and a person is employed by that branch or agency, the legislation of that Party concerning liability for contributions shall apply to him;
