Two ways display documents for you: 1)I show you photo in advance on which on all important data added paint. You want know whether this document original or not? You give me address site(service) on which i can check free authenticity(validation) document that i showed for country which you need(don't confuse with verification on site). If this person is in database, then i take screenshot result and show this screenshot you, i will add paint on all important data.
If such person is not in database, then your right refuse from purchase.
Very important that you understand: i do not send request for verification on site, i only check this document on authenticity, search for me address such site yourself for country which you need. If you give me address site specifically for verification on site, then your request will be rejected.
If for you does not matter document this original or not original, then see point two.
2)You need used documents for resale (you bought and you sells it for even more money), i show you photo in advance on which on all important data added paint.
