DP act use on both parties even he is give or taker. DP act doesn't give to any protection to dowry giver. DP act is given protection to " first person aggrieved " . Either he is the husband or either she is wife.
There are some points they can raise in HC.
1. they did n;t give dowry. They gave only stridhan.
2. you didn;t take any DM permission (If require as per state amendement)
3. They never said they gave dowry.
4. And it is too late to file case means as per some state amendments there are one year time limit to file .
