Hi Dear,

EWS certificate is issued to the persons belonging to the Economically Weaker Section (EWS) category of the society. The EWS certificate is valid for one year from the date of issue. So, if your EWS certificate is issued with 12 months immediately preceding the date of submission of documents in your form, then the EWS certificate stands valid. In any other case you'll have to get a fresh EWS certificate made.

Hope this helps.. Good Luck
