May a firm sue a former divorce client in an unrelated personal injury action?

Short answer The committee said Rule 1.9 did not bar the new accident representation on the stated assumption that the divorce client was a former client and the matters were unrelated. The firm still could not use former-client confidential information to that client’s disadvantage.

Plain-English summary

A firm lawyer was retained for an accident claim against a driver whom another lawyer at the firm had represented in a completed divorce. The firm had recently communicated with the driver about returning divorce-file papers.

The committee treated the accident and divorce as different, not substantially related matters under Rule 1.9. It said imputation meant the new lawyer’s personal lack of file knowledge did not alone settle the rule question, while the firm’s confidentiality duties persisted. The opinion also flagged Rule 1.7 if the driver’s client relationship had not truly ended.

Currency note

This opinion was issued in 1997, before North Dakota's 2006 revisions to its Rules of Professional Conduct. The later North Dakota Opinion 06-05 states: “On August 1, 2006, material changes to N.D.R. Prof. Conduct 1.10(a) will take effect.” Subsequent rule amendments or later opinions may have changed the analysis. Treat this page as historical context, not current guidance. Verify against current rules before relying on any specific rule, deadline, or requirement.
