1. Not performing Saptapadi does not make marriage null and void. If her advocate astutely places the facts, you will be hauled for "rape" charges.
2. She can place matrimony ad. on the court record. But she has to take a lot of steps to prove it as per law.
3. You will not get either quash in Section 125 cr.P.C. nor stay. You have to contest this case before the trial court.
Lastly your demand that she should stay away from you and you will visit her once in a year and your parents' condition she should leave the child along with them, is absolutely unreasonable and if the judge in trial court or High Court will come to know of such condition, he will haul you and your parents routhlessly.
