Questions & Answers about El informe ya está escrito, así que puedo descansar.
Está escrito uses estar + past participle to describe a resulting state: the report is now in a written/finished condition.
- El informe está escrito = the report is written / has been written
- It focuses on the current state
By contrast, ser + past participle is the true passive voice and focuses more on the action:
- El informe es escrito por Ana = the report is written by Ana
That version is grammatical, but in everyday Spanish it is less natural here. In this sentence, Spanish prefers está escrito because the important idea is that the report is done.
