In a previous topic on the German passive voice, I explicitly explained what it means for a voice to be passive, how it can be made passive, when it can be used and why it should even be used at all. In this topic, I have further explained the inclusion of a modal verb in a passive sentence.
Recall that a passive sentence/voice can formed with either werden or sein depending on whether it is ‘Vorgangspassiv‘ or ‘Zustandspassiv‘ respectively. In the case of passive with modal verbs, it is only formed with werden. This means that the German modal verbs can only be used in the ‘Vorgangspassiv’ or processual passive voice.

A passive voice is usually formed with a modal verb to either show politeness or suggestions and can only be expressed in the present and past tense. when expressed in the present/ past tense, the modal verbs are conjugated in the second position to the object turned subject while the auxiliary verb werden which means “be” here, goes to the end of the sentence in its finite form directly after the Partizip II. Hence, the structure of a passive sentence with a modal verb becomes “Modalverb + … + Partizip II + werden”.
German passive voice with modal verbs in the present tense
In the present tense, the modal verbs are conjugated in the present tense and maintain their meanings as illustrated below.

| 3. Das Auto kann nicht repariert werden. | The car can not be repaired. |
German passive voice with modal verbs in the past tense
In the past, the passive voice of modal verbs are often expressed in the simple past tense which is called Präteritum in German. Expressions in the perfect tense could be possible but then is more complex and not usually used. See illustration in the präteritum below;
| Pronouns | Müssen | Können | Dürfen | Sollen | Wollen | Mögen |
|---|---|---|---|---|---|---|
| ich du er/sie/es wir ihr sie/Sie | musste musstest musste mussten musstet mussten | konnte konntest konnte konnten konntet konnten | durfte durftest durfte durften durftet durften | sollte solltest sollte sollten solltet sollten | wollte wolltest wollte wollten wolltet wollten | mochte mochtest mochte mochten mochtet mochten |
