Re-issue of Indian Passport

My wife applied for new Passport alongwigh me. In my case they entered name of my wife without asking any document but in case of my wife they asked and relied the voter id and bank passbook but there my name was without middle and surname and as such they included only my first name as her busband. (Both the Passports are still pending to be issued for submission of Police Verification Report).
In due course my wife applied for correction of entries in her voter id card which is under process due to elections. May she use my Passport as supporting document for inclusion of my complete name in her passport?
What will be procedure of re-issue of her Passport?
