482 quash or discharge - which is better

When you get date for" Argument on charge"

Ask opposite party not to oppose you, and get discharge. 

Firstly note it, section 498A IPC complaint is not a private complaint of the wife, it is State complaint according to FIR lodged by the wife against you, and she has no say in the matter while charges are being framed by the court against the accused in the State case.

Secondly,  the change of her stand/statement with regard to her FIR can be possible and if the public prosecutor doesn't object to this allow the court to acquit the accused the matter ends there itself. However if the State is not satisfied with the acquittal order can move appellant court in appeal and can even seek prosecution of the wife for changing her statement and ask the court for charging her for offence of perjury, it means dual trouble for both parties.

Thirdly going to High Court by both requires either joint quashing petition filed under s 482 Cr.P.C read with Article 227 Constitution of India or by the husband when the wife is made one of the respondent along with the state, in that case  the wife has to appear in court and state her consent for quashing of the FIR and proceedings under s 498A IPC, the matter resolved in High Court gives finality for the matter for even.

Sir

Suppose discharge is given then is it equal to acquital order, from my point of view

Or what does it mean generally and in the eyes of law.

Not agreed with vishak.

Legally It is case between you and state. 

And NOT between you and your wife. 

That's why you have to go to HC and file quash petition u/s 482crpc.

Your wife and her family is only witness in the court. And I/O and other police officers are also witness.  

It is MANDATORY to go HC for quash
