Filing heabus corpus petition in this cae will perhaps be most stupid idea in this case.
In this case the court will direct the police to bring her and while reaching the high court she will tell clearly that she is voluntarily living away from you. The petition is likely to be dismissed.
Given facts indicate that she is not forcibly keeping in custody against her will.
You asked “Can I bring back my son and wife forcibly from her parents” Sorry you are not living in Taliban regime where a woman can be kept in jail for escaping from torture of husband.
Some one will advise you to file case for restitution of conjugal rights
RCR notice is a time tested tool to compel wife to raise true/false complaint of dowry/domestic violence against husband with family including married/unmarried brother/sisters wit/without their spouse. This way husband leaves her with no choice but to spoil his family even if she does not want to do so.
This forum is full of such cases where husband with parents/siblings faced such criminal charges.
After visiting jails people realise that the situation inside Indian Jails is not as rosy as shown in movies and the cops are also comedians in movies which is not in actual life.
You also want to know “can her parents lodge any criminal case against me for bringing back my own son and wife” Answer is CERTAINLY YES.
“do not want to lodge any case under sec9, or neither under ,97 crpc” Before even thinking of this action (even inyour dream read the section before beingmisguided
Section 97 in The Code Of Criminal Procedure, 1973
97. Search for persons wrongfully confined. If any District Magistrate, Sub- divisional Magistrate or Magistrate of the first class has reason to believe that any person is confined under such circumstances that the confinement amounts to an offence, he
may issue a search- warrant, and the person to whom such warrant is directed may search for the person so confined; and such search shall be made in accordance therewith, and the person, if found, shall be immediately taken before a Magistrate, who shall make such order as in the circumstances of the case seems proper.
Such is not your case.
So in your case reconciliation is the only solution whether you like it or not.
