Questions & Answers about Ya he revisado la documentación y el justificante del pago.
He revisado is the present perfect: haber + past participle.
- he = I have
- revisado = reviewed/checked
In Spain, the present perfect is very commonly used for actions connected to the present moment or a recent time period:
- Ya he revisado... = I’ve already reviewed...
By contrast, revisé is the preterite (I reviewed / I checked) and is more likely to be used for a finished action placed clearly in the past.
This is especially worth noticing because in much of Latin America, speakers often use the preterite more often where Spain Spanish might prefer the present perfect.
