Forming the passive voice with ser + participle (Compound tenses -passive voice)

In English, an active sentence is turned into a passive one (also known as the passive voice) as follows:

The cat eats the mouse. → The mouse is eaten by the cat.
The cat has eaten the mouse. → The mouse has been eaten by the cat.

The passive voice can be used both in simple tenses, i.e I go, I went, I will go, and compound tenses, i.e I have gone, I had gone.

To learn how to form the passive with simple tenses see Forming the passive voice with ser + participle (+ por) (passive - simple tenses).

Take a look at passive sentences in Spanish, conjugated in compound tenses:

Los platos han sido lavados. 
The dishes have been washed.

Nosotros hemos sido condenados por la Corte a 20 años de cárcel.
We have been sentenced by the court to 20 years in prison.

Las manzanas habían sido horneadas.
The apples had been roasted.

Los candidatos habrán sido elegidos por la tarde.
The candidates will have been chosen in the evening.

As you can see, the passive voice is formed by verb ser conjugated in a compound tense and a participle.

Note that the past participle agrees with the subject of the auxiliary ser:

platos → lavados

nosotros → condenados

manzanas → horneadas

candidatos → elegidos

In order to turn a sentence from active to passive voice, the tense of the auxiliary ser must be the same as the tense of the main verb of the active sentence. For example:

El cliente ha rellenado el documento. → El documento ha sido rellenado por el cliente. (present perfect tense)

El cliente había rellenado el documento. → El documento había sido rellenado por el cliente. (pluperfect tense)

El cliente habrá rellenado el documento. → El documento habrá sido rellenado por el cliente. (perfect future tense)

El cliente habría rellenado el documento. → El documento habría sido rellenado por el cliente. (perfect conditional tense)

Notice that, just like in English, the pattern is as follows:

  • The object becomes the subject.
  • We use the auxiliary verb ser (not estar) in one of the compound tenses, followed by the past participle of the verb.
  • We use the preposition por to introduce the complement.
