If a Spanish verb has an irregular past participle we say this verb is irregular in the perfect tenses because perfect tenses conjugations use the past participle of the main verb.
Spanish irregular verbs conjugated in El Pretérito Perfecto Subjuntivo
The present perfect subjunctive in Spanish is formed by the auxiliary verb haber in the present subjunctive, followed by the past participle of the main verb.
Look at the following examples:
Es probable que haya hecho toda la tarea antes de ir al concierto.It's probable that I'll have done all my homework before going to the concert.
No creo que hayas puesto los libros en el lugar equivocado.I don't think that you've put the books in the wrong place. [you = tú]
No pienso que haya escrito la crítica para ese periódico.I don't think she has written the review for that newspaper.
Es posible que hayamos frito demasiado las patatas.It's possible that we have fried the potatoes too much.
No puedo creer que hayáis absuelto al criminal tan rápido.I can't believe that you all have absolved the criminal that fast.
Remember that the construction tal vez (maybe) accepts both indicative and subjunctive moods without any change of the meaning.
