Hc has quashed 498a.what should be done with nbw after this?

You or your advocate can approach the trial court.

Advocate P.Venu is right . U can submit the said order in the Rial Court from where the ORDER was passed. 

thank you sandeep sir and venu sir.

If you are in possession of the certified copy of the high court quashing the charges agaisnt your relatives agaisnt whom NBW is state to be pending, you may approach the trial court with a petition/memo enclosing the high court order copy, stating that the high court has quashed the case against the said individuals hence the NBW pending agaisnt them may be recalled and they may be discharged from the case.

You can take the help of your advocate to draft the petition or memo for this purpose.
