According to Spanish Procedure and Arbitration Acts, awards can be enforced in Spain before the Courts.
In the Spanish legal system, enforcement is always purely jurisdictional, since it is designed in the enforcement process as intrinsic to the jurisdiction. Therefore, the right is first declared and then enforced in other words, first comes the judgement, next comes the execution of the judgement.
This general outline does not change when the process is substantiated at the place of arbitration, since a final award is a title assimilated to the court ruling, whose effects, in its enforcement aspects, are deemed to be equivalent to the effects of a court ruling and has the force of res judicata.
Therefore, the function of judging is handled by the arbitration body chosen by the parties. The decision of that arbitration body the award is enforceable by the State bodies that have recognized judicial power meaning that the function of "enforce the judgement" of the award is conferred to the Courts of First Instance and Commercial Courts.
The enforcement must be asked before the competent court by the one who got the favorable pronouncement, by an enforcement claim within five years since the judgment or resolution is definitive.
The opposition to the enforcement is configured as a judicial proceeding, but the possibilities to opposite to the enforcement are limited, just in case of payment of the debt amount, compensation or similar could be accepted.
Spanish legislation states that the award is enforceable even though it has not become final due to an annulment action; although, the affected party has the possibility of obtaining the suspension of its enforcement by providing a guarantee.
