For the passport process you only need to present your IPR, or a birth certificate made by Renap, which has a CUI No. and no more than 6 months after it was issued. The renewal of the passport can be done 06 months before it expires.
The CUI is brought by the DPI and automatically printed on the recent birth certificate, you can process it with either of the two and if you do not have it you can not process a passport. You have to transact DPI that takes between 4 months to deliver it to you.
It came to me quickly like a month. If he has already expired, he must bring a recent birth certificate and also CUI. If you do not have that number, you have to process the passport first and then.
