who are you ? please clarify.

One can lodge a FIR, if he reasonably believe or have information of commission of a cognisable offence.

a counter can be filed by invoking dowry laws only that say giving and taking dowry, both are actionable.

i agree with Adv Gupta

without reading your FIR noone can guide you properly so better to consult any local advocate or send your copy of FIR at adv.kamal.grover@gmail.com
