Dear Friend,
After taking Divorce she is a free individual from any matrimonial relations with you and also with your all family members legally she can not be treated as Bahu for your Parents and she also can not claim any domestic relationsip wit any of your relative after getting a divorce from the Court.
Thus she can not opt for any domestic Violence or matrimonial offence of cruelty against your parents in India .
However, she is free to file any civil or criminal case/ complaint against them as an independent person with a separate legal entity having no relations with them at all. Thus all claims under matrimonial relations are now barred for her after the divorce situation.
Other to above, you are advised to give a certified copy of your Divorce decree to your Parents in India as an precautionary measure. This will help them in trouble.
