In bond paper format for different institutions

Please help me anyone regarding this query mentioned below:
In bond paper format for different institutions its written that it should be in presence of two witnesses. Their signatures are needed and copy of Aadhaar and pan card of the witnesses will be needed to be submitted along with the bond paper. Are my parents eligible to be as witnesses ? Can I submit their Aadhaar card and pan card xerox along with the bond paper? If not then what’s the solution for the same?
