Hello Aspirant

For appearing in NEET UG exam the certificate is needed for the state in which you are permanent residence and you are permanent address on which state you have. Now you are saying that you have resident houses in Karnataka in Maharashtra. Parents lived in Karnataka and studied in Karnataka so your domicile certificate will be preferable from the state of Karnataka. The state in which you are permanent resident li and living not less than 10 years will be the state for your domicile and from this state you have to get domicile certificate to avail the opportunity of 85% state quota in NEET UG exam.

Hope this helps.
