Can 498a be withdrawn after chargesheet has been filed

Section 498A of the IPC deals with a non-bailable offence, which applies to a husband, or relative(s) of a husband, of a woman, who is/are subjecting her to cruelty.
The offence under section 498(a) of IPC is a Non-Compundable offence. Due to this it cannot be withdrawn if the FIR is registered and chargesheet is filed.

According to your query, you've said that -"Court is asking for any recent Judgement!". So for this there hasn't been any recent matter where a petition under 498(a) have been withdrawn.

However, if your wife if is ready to withdraw the matter, then you may proceed to file an application of withdrawal of case to the High Court of jurisdiction.
While doing this make sure that you mention that this is an application for the High Court to exercise its powers under Section 482 of CrPC and attach written affidavits from all members of your family stating that they have no objection to this withdrawal.

Then Section 498-A case will be quashed. You can also document the settlement that has been agreed between you and your husband and then file a Quash petition in HC and the case would be quashed.

Hope it Helps
