Hello,

i advise yout o tender a reply so that in case he files a acase then you may take the defense that you tendered to the legal notice. 

Send a reply through an advocate.

regards

See reply can be simple on letter head denying all allegations and bringing on record that he resigned himself and same was duly accepted by company.

Further it would be better if you take assistance of lawyer.

1. You are not obligated to reply to any legal notice (ie notice served through an advocate). 
2. However, your time certainly is of value. You would surely like to do your best to avoid getting into litigation. So I would advice you to respond to this legal notice by an advocate.... Stressing that you would sue your ex employee for malicious prosecution/ malacious judicial proceedings if he/she invokes judicial mechanism based on wild and baseless allegations. 
3. Whatever is stated in 2) usually does the trick. Respond by way of legal notice only ie appoint an advocate. However, 
4. If your ex employee still initiates any judicial proceedings, either civil or criminal, first of all your​ advocate has to defend you in it; seeking compensation for waste of your time and costs involved; and secondly after the judicial proceedings reach their logical conclusion in your favour, you must instruct your lawyer that you intend to sue your ex-employee for malacious prosecution/ malicious judicial process. 
5. I'm based in Mumbai, and I understand you too are. I'm prepared to handle this matter; right from replying to the legal notice served upon you, to defending you in court and intiating the suit for malacious prosecution/ judicial proceedings. 
6. Your contact details aren't shown to me here. Please leave them in feedback so that we can get in touch. You will need an appointment at my office for further consultation and briefing and then we will take it from there.

Giving a reply to the legal notice need not be mandatorily given by a lawyer.

A response on the letter head of the company would also be admissible in court, if the employee goes on to file a case against company in future.

You can avail services of a lawyer, if you have any doubts as to what has to be written in the reply.

you must contact a local lawyer and reply to legal notice 

2) deny allegations made in legal notice 

you can reply to the notice for record i.e. keeping records straight

mention the company's stand in clear and unequivocal terms as to how this employee had himself resigned

you need not have the reply sent through a lawyer

the reply can be on company's letterhead itself

just be precise and clear 

also warn the employee of necessary action if he continues with his tactics for extracting compensation from company

Hello

       The employee resigned due to his misconduct on papers but generally organizations demand resignation from employees. Therefore he may be aggrieved and hence the notice. Send a reply through a lawyer as it may have legal implications.

Regards 

Dear Sir,

It is better to avoid any reply to such baseless legal notices.  If you reply in simple tone also the employee may think your company is afraid of such legal notice.  If he ventures to file any legal proceedings then company has many defenses to putforth.  As such you need not disclose any of your defense at this stage.

Dear Client,

Through advocate , reply will have effect. Mere reply that, he himself has offered resign and subject to disciplinary action for misconduct. 

Its better to appoint a lawyer to give a detailed response avoiding legal loop holes.

Since you have received a legal notice, it becomes your duty to issue a reply notice either by yourself or through your lawyer denying all the allegations leveled in the legal notice.

This step will help you to defend your interests in the court of law if he prefers to approach court seeking relief or remedy.

You should reply against said  legal notice through an lawyer. 

1. Employer & Employee disputes are taken very very seriously for the labour /industrial courts.

2. Address the issue ONLY thru a proper lawyers notice, supported by proper documentary evidences.
