(1) The testator, upon making a testamentary burden the purpose of which they have specified, may leave it to the person charged or to a third party to determine the person to whom performance is to be rendered.
(2) Where the person charged has the right of determination, and where they have been ordered by a final judgment to fulfil the testamentary burden, the plaintiff may specify a reasonable time limit for them to fulfil the testamentary burden; after the expiry of the period of time the plaintiff is entitled to make the determination if the fulfilment is not effected in good time.
(3) If a third party has the right of determination, it is exercised by declaration to the person charged. If the third person is unable to make such a determination, the right of determination devolves to the person charged. The provision under section 2151 (3) sentence 2 applies accordingly; those concerned within the meaning of this provision include the person charged and those entitled to demand the fulfilment of the testamentary burden.
