Hello there,

To get a domicile certificate there are some requirements

1) You should be resident of the state from atleast 10 years. Must include some documents like rationcard or electricity bill etc.

2) Must have passed class X or XII from the state itself.

now , for getting a domicile of WB one must get the documents verified in SDO office/Special cell of WB police after which the application eill be sent to the SDO for signing.
Alternatively one can also get a domicile from the municipal commissioner, Counsillor of the Corp. etc but those may not be considered for domicile in NEET.

Check out the official site of WB govt and download the form of domicile certificate

good Luck !
