In Islam the husand is given the power to divorce unilaterally. Once you give her talaq, which may be in ahsan, hasan or biddat (triple talaq) forms. She can try implicate you in 498a/406/DV Act cases. It is advisable to give her talaq in ahsan form which is the most approved form as per law of Shariat. I'd explain the process :
Ahsan - most approved form of talaq – most honourable & fair – with ample opportunity for reconciliation – least hardships to woman
Procedure :-In period of tuhr (period of purity) at that time during her mensuration cycles – when she is capable of begetting a child – first pronouncement of Talaq – intention should be manifest – thereafter abstain from s*xual intercourse for 2 more tuhrs -Period of iddat commences right after first pronouncement – Talaq becomes Final at the end of 3rd tuhr provided husband has not cohabited in this period. (VR also applicable) Iddat is co-terminus with 3rd Tuhr – revocable during iddat. She need not maintain anymore iddat.
On how to fight a false 498a - if you apprehend that this may happen to you - you may start by sending some protective intimations that would greatly mitigate the force of a false case against you.
