Q. Many years ago I represented a husband in a divorce. The ex-wife just came to me and wants me to represent her in a personal injury matter. Can I?
A. RPC 1.9 prohibits a lawyer from representing someone in a matter that is the same or substantially related to a matter in which the lawyer previously represented a client. Although there are many facets of this rule when applying it to specific situations, one of the major concerns is to protect confidential information that may have been gained in the prior representation that could be used to the detriment of the former client.
