Wife hacked social media account.

You must have shared your password(s) which resulted in taking your information(s) and use it against you in the court ?

No way Sir.

His advocate who left her told me about her hacking. 

Without having evidence for she hacking your social media accounts you cannot take any legal action against her for invading your privacy.

In fact you can give a complaint to the cyber police only about this with the proofs of her such illegal acts.

But in what way that has aggrieved you has to be explained, mere reporting of hacking may not constitute any offence.
