Dear Client,
I want to let you know that,you are entitled to seek divorce on grounds of cruelty, even though you reside with your wife. Till now, you have been suffering from physical as well as mental cruelties. Section 13(1)(ia) defines cruelty to include both physical as well as mental. All the audio recordings of her shouting, threatening, and trying to hit your son can be used in evidence to prove your case.
There is no such law that requires you to leave the house before filing for divorce. Living together will not make you ineligible to seek divorce, especially when your concern remains the welfare of your child. It may be that desertion for 6 months forms part of proving desertion advice by your lawyer; in this case, it is a case of cruelty instead of desertion.
Regarding the question you have further sought clarification on, your wife has absolutely no rights on your parents' property or properties. As per Hindu law, she is not entitled to claim any rights over your parents' ancestral or personal properties considering the fact that they have been staying apart for 9 long years and did not care to get in touch with her. If she files any claims of this nature, your parents will likely be impleaded in that case but they will not automatically be liable. It would be a declaration of their non-involvement with court action.
There is very crucial presentation of all the evidence for the case, and a sound family lawyer would be capable enough to help create a strong case.
Thank you.Hope this answers your query.
