if she file Dowry case saying they gave dowry and took then its burdon on you to prove it you did not demanded any dowry. Even she file False case
if you file they gave dowry without demand, they will be charged under DP3 and you will not be charged for taking it. as you are aggrieved person (read DP7(3) option)
who ever file case 1st they are right, and for a women its bonus point
do not file Divorce, send lawyer notice then file RCR, so you can show later in divorce that you tried to save your marriage.
other whatever proofs men have no judge is checking or asking nor beleive in you.
