Article 276.

Article 277.
The Spanish Courts and Tribunals shall provide foreign judicial authorities with any cooperation required of them for carrying out their jurisdictional duties pursuant to the terms of international treaties and conventions to which Spain is a signatory, and failing this, on the basis of reciprocity, according to the terms of the following article.
Article 278.
1. If the existence of reciprocity is attested to or if this is offered by the requesting foreign judicial body, the provision of international cooperation shall only be refused by the Spanish Courts and tribunals :

2.° When the content of the action to be carried out does not correspond to the attributions proper to the requested Spanish judicial authority. In this case it shall remit the application to the competent judicial authority, informing the requesting authority of this fact.
3.° When the communication containing the cooperation application does not fulfil the requirements of sufficient authenticity or is drafted in a language other than Spanish.
4.° When the object of the requested cooperation is manifestly contrary to Spanish public order.
