Breakdown of Depois que o contrato for assinado, a mudança pode começar.
Questions & Answers about Depois que o contrato for assinado, a mudança pode começar.
Depois que introduces a clause with a verb (a full action/event): Depois que o contrato for assinado = after the contract is signed.
Depois de is normally followed by a noun or an infinitive:
- Depois de assinar o contrato, ... = after signing the contract
- Depois do contrato, ... = after the contract (less specific)
for assinado is future subjunctive of ser (for) + past participle (assinado) in a passive construction.
Portuguese typically uses the subjunctive after time expressions like depois que, quando, assim que when the event is in the future or not yet completed.
So it’s “after the contract is signed (in the future)” → Depois que ... for assinado.
será assinado (future indicative) is grammatically possible in some contexts, but it often sounds more like a firm prediction/statement and is less common after depois que than the subjunctive in everyday Brazilian Portuguese.
