In the list of documents by SPSC, there is 'a character certificate from a responsible person not related to the candidate'. I have two queries regarding this;

1. From whom should we get this, any officer of 17 or 18 grade in government, any authoritative person from our university or the person from whom we will get our other documents attested?

2. What is the procedure of getting this certificate, do we have to write it and print it ourselves and then get it attested/signed by any of the persons mentioned above or do we have to ask the person to write it and attest it?
