A lawyer is a term used to designate anyone in the legal profession, including a barrister, solicitor, and attorney.
Lawyers cannot practice in a court of law. They should be enrolled in a State Bar Council and pass the AIBE.
Lawyers have less experience than advocates since they need to pass the AIBE to practice in court and get the knowledge required to represent clients.
An advocate is a legal professional who has passed the AIBE and obtained a license to represent the client in a court of law and argue their case on their behalf.
Advocates are more experienced than lawyers since they have the opportunity to practice in all courts in India in different legal matters.
The responsibilities and duties of an advocate are to represent the clients in court and plead on their behalf.
