Opposing lawyers have the duty to represent their clients. An opposing lawyer owes you no duty, and in fact, you may feel an opposing lawyer's actions are directly contrary to your wishes or interests. That is why you may have retained your own lawyer, to represent your interests and advise you.
The Law Society reviews issues of member conduct. A lawyer representing a client's interests in a dispute is not misconduct. However, if you believe the opposing lawyer's conduct is contrary to the Rules of the Law Society or The Code of Professional Conduct, please bring forward a complaint.
