Artikel 20

1. Persons who reside in the territory of a Contracting Party other than the competent State and who satisfy the conditions for entitlement prescribed by the legislation of the latter State, regard being had, where appropriate, to the provisions of Article 19, shall receive in the territory of the Contracting Party in which they are resident:
(a) benefits in kind, provided at the expense of the competent institution by the institution of the place of residence in accordance with the provisions of the legislation which the latter institution applies, as if these persons were affiliated to it;
(b) cash benefits, paid by the competent institution in accordance with the provisions of the legislation which it applies, as if these persons were resident in the territory of the competent State. However, by agreement between the competent institution and the institution of the place of residence, cash benefits may also be paid through the latter institution, on behalf of the competent institution.
2. The provisions of the preceding paragraph shall apply, mutatis mutandis, in respect of benefits in kind to members of the family who are resident in the territory of a Contracting Party other than the competent State.
3. Benefits may also be paid to frontier workers by the competent institution in the territory of the competent State, in accordance with the provisions of the legislation of that State, as if they were resident in its territory. However, members of their family shall be entitled to benefits in kind under the same conditions only if there is an agreement to that effect between the competent authorities of the Contracting Parties concerned, or failing that, except in case of emergency, if there is prior authorisation by the competent institution.
4. Persons to whom this Article applies, other than frontier workers or members of their families, who are temporarily resident in the territory of the competent State, shall be entitled to benefits in accordance with the provisions of the legislation of that State as if they were resident in its territory even if they were already receiving benefits for the same case of sickness or maternity before taking up their temporary residence.
5. Persons to whom this Article applies who transfer their residence to the territory of the competent State shall be entitled to benefits in accordance with the provisions of the legislation of that State, even if they were already receiving benefits for the same case of sickness or maternity before transferring their residence.
