In general, a foreign personal representative may sue and may be sued in DC pursuant to DC Code, sec. 20-342. You may file suit in DC against a foreign personal representative if the foreign personal representative has actual knowledge of a claim barred in another jurisdiction that does not rise to the level of a "final judgment" under the Full Faith and Credit Clause of the United States Constitution. See Richard v. McGreevy, 136 DWLR 170 at pp. 1917-1919 (DC 9/2/08.) However, please consult with your counsel regarding issues of appropriate jurisdiction prior to filing suit against a foreign personal representative.
