Can an Attorney Represent Both Spouses in a Divorce or Both Parents in a Child Custody or Support Case?
The answer is no.
Representing opposing parties to any lawsuit (and even uncontested divorces or uncontested child support and custody cases are lawsuits) is absolutely prohibited. Any attorney who indicates he or she can represent both parties in having a domestic agreement approved by the court or obtaining a divorce is committing an ethical violation. See South Carolina Rule of Professional Conduct 1.7(b)(3) and comment 21.
