Rural Study Certificate And Non Creamy Verification Certificate

To claim a seat under the rural quota in KCET 2020, recently we came to know that with the Rural Study certificate from 1st to 10 std, we must submit a verification certificate that parents of the candidate should not come under the creamy layer, for General Category, we came to know that parents income must be less than 8.0 LPA, for 3 years. We applied for an Income certificate and Non creamy layer certificate, our Income is as below: 2017-18 :- Rs.9.13 L ( Total Gross income) and Rs. 7.78 L ( total Taxable Income) As per ITR 2018- 19 :- Rs. 9.00 L ( T G I ) and Rs.8.13 L ( T T I) 2019-20 :- Rs. 7.97 L ( T G I ) and Rs.6.97 L ( T T I ) So, we applied for a certificate to the concerned department by submitting the last year ITR, legally is it okay if we get certificates, and shall we claim rural quota without any legal disputes in the future. We request your Advice, thanks, and regards, nagraj
