9 Which is the competent authority to turn to in cases of disputes and other legal issues?

Spanish courts have international jurisdiction for such proceedings if one of the spouses/partners is of Spanish nationality or has his/her habitual residence in Spain (Art. 50-60 LEC). Both subject-matter jurisdiction and local jurisdiction belong to the court of the district in which the spouses/partners had their last common habitual residence or, subsidiarily, to the court of the district in which the defendant has his/her habitual residence.

There are also specific regulations for cases in which there is no international jurisdiction (Art. 36 LEC).
