Where an employed or self-employed person has been subject successively to the legislation of two Member States during the period separating two dates for the payment of family benefits as provided for by the legislation of one or both of the Member States concerned, the following rules shall apply:
The family benefits which the person concerned may claim by virtue of being subject to the legislation of each one of these States shall correspond to the number of daily benefits due under the relevant legislation. Where such legislation does not provide for daily benefits, the family benefits shall be granted in proportion to the length of time during which the person concerned has been subject to the legislation of each one of the Member States in relation to the period fixed by the legislation concerned.
Where the family benefits have been provided by an institution during a period when they should have been provided by another institution, there shall be an adjustment of accounts between the said institutions.
For the purposes of subparagraphs (a) and (b), where periods of employment or self-employment completed under the legislation of one Member State are expressed in units different from those which are used for the calculation of family benefits under the legislation of another Member State to which the person concerned has also been subject during the same period, the conversion shall be carried out in accordance with the provisions of Article 15 (3) of the implementing Regulation.
Notwithstanding the provisions of subparagraph (a) in respect of dealings between the Member States listed in Annex 8 to the implementing regulation, the institution bearing the costs of the family benefits by reason of the first employment or self-employment during the period concerned shall bear such costs throughout the entire current period.
