Perfect tenses shared by the two languages are all in the indicative mood: the present perfect (I have seen, he visto), past perfect (I had seen, había visto), future perfect (I will have seen, habré visto) and conditional perfect (I would have seen, habría visto). The past perfect is also known as the pluperfect.
Spanish also has a preterite perfect tense that can refer to past events (hube visto), but it is seldom used in modern Spanish. In addition, Spanish has two perfect subjunctive forms, the present perfect (que haya visto) and the past perfect (que hubiera visto).
