Gather all relevant evidence, inform the appropriate legal or regulatory authority, seek court protection if needed, and ensure the client is advised independently and transparently at every step.

To protect a client’s interest if they are being exploited or misled by another lawyer or official:
Meet privately with your client to understand the situation and assess any undue influence or exploitation.

Advise the client clearly about their rights and risks, and document all communications.
Challenge unethical or exploitative actions by raising concerns with the appropriate authorities or regulatory bodies (such as the Bar Council in India).
Consider withdrawal from representation if the client insists on a harmful course of action and cannot be dissuaded.
Preserve confidentiality while ensuring you do not mislead the court or third parties.

To protect a client from exploitation or misleading tactics by another lawyer or official, a lawyer must uphold their fiduciary duty to the client, ensuring they prioritize their client's interests and act with loyalty, confidentiality, and diligence. This involves actively investigating, disclosing any relevant information, and ensuring the client is fully informed and capable of making an informed decision.
