There is no reason for the previous lawyer to furnish NOC, however the NOC will not play any role if you have decided to terminate the services of the previous lawyer, you can attach the copy of the notice to the previous lawyer about this in your vakalatnama given to the new lawyer who will take care of further issues in this regard.

You are repeating the same question in different modes.

You were advised to issue a legal notice to the previous lawyer stating that you have decided to terminate the vakalatnama given to him hence request him to give NOC, even if he do not respond, you ca proceed with the case through your new lawyer as suggested above. 

- Legally , you have right to replace the lawyer , and the lawyer cannot refuse to issue NOC 

- You can send a message/notice to the present lawyer for not to appear in your case , and thereby inform him that you have already engaged a new lawyer 

You can change your lawyer without his noc if he has refused to give the same. You need to clear his legitimate outstanding fees 

Dear client, 

You can change your lawyer at any time and appoint new lawyer. You have to take no objection from him and if he denied to give you no objection, you can file affidavit stating the fact in the court and appoint new advocate

Dear sir, 

You may engage a new lawyer and give an affidavit to the court where case is pending giving all details of the new advocate and change previous advocate. The affidavit will be attested by Indian Embassy. Plus, you may appear in court proceedings through virtula mode as well.

An email will suffice

Dear Client,

The requirements for canceling services with a lawyer can vary based on your location and the terms outlined in the agreement you have with the lawyer. In many cases, a simple written notice may suffice, but it's often better to follow the specific guidelines outlined in your contract or engagement agreement with the lawyer. Sometimes, contracts stipulate the method or form of cancellation, which might include sending a formal letter or notice. Others might accept an email or a written statement. However, it's crucial to ensure that whatever method you choose meets the legal requirements and the terms of the agreement. If you're unsure about the appropriate method or if your agreement doesn't specify, it's a good idea to reach out to the lawyer or their firm directly to confirm the correct procedure for canceling services. This can prevent any misunderstandings or potential issues down the line.
