Hello,

There are some certificates which as it's validity period. if you provide any document which has crossed the validity then you will be rejected then and there. So don't get lazy or it will cost you your career.

if there is any document which need renewal then make renewal. Make certificates from the source. don't go for other places which will be considered as illegal. If it is made from any institution then make it from an institution only.

Character certificate is valid for 6 months only. so make a new one from the institute only with proper documents.

Hope it helps!
