You technically don’t have to be represented by a lawyer. However, it’s important to remember that the mediator or arbitrator cannot give legal advice and will be a neutral party. In other words, it isn’t their job to act in your best interests. It’s your lawyer’s duty and commitment to advocate to protect your best interests, which is the biggest reason to have counsel. They can’t tell you if the deal you are making is good, bad, or indifferent. Further, your lawyer can help you understand any options presented to you and make sure you know how accepting any decision or course of action might impact your future.
