The opposition made by the accused, within the time limits provided either in the third or in the fifth paragraph of article 527, must be made:
– either by letter addressed to the head of the registry of the court which handed down the contested decision. The letter must be sent within the prescribed time limit, as evidenced by the postmark;
– or by an oral statement made to the head of the registry, recorded and signed by the latter and by the defendant himself or herself or by a lawyer or a special proxy. The power of attorney shall be annexed to the document drawn up by the head of the court registry.
In both cases, the accused must, in support of the opposition, give or send to the head of the court registry the letter of notification or inform him of the references on it.
Declarations of opposition shall be entered in a register.
