If I represent business buyer, can I represent seller in a separate matter?
Q. I currently represent the buyer of a business. Can I represent the business’s seller in a wholly unrelated matter?
A. Under IRPC 1.7(a)(1) this is a direct conflict. Comment  to that rule says, as an example of a direct conflict, “if a lawyer is asked to represent the seller of a business in negotiations with a buyer represented by the lawyer, not in the same transaction but in another, unrelated matter, the lawyer could not undertake the representation… .” However, both the Rule and the Comment make it clear that the representation could be undertaken if both clients give informed consent.
