After admission to the Virginia bar, Lee practiced law in Alexandria (for much of this time part of the District of Columbia), as did his brothers Richard Bland Lee and Edmund J. Lee, his uncle
Arthur Lee (at least technically), and cousin/brother-in-law
Ludwell Lee. In addition to his government duties described below Lee had a private legal practice, and one of his clients was George Washington (from 1785 until his appointment as Attorney General as described below in 1795). He also was the Alexandria city prosecutor until resigning that office in 1794, and a local judicial position in 1801. Like his uncle squire Richard Lee, Charles Lee also held appointed positions as (most lucratively) tax collector for the Port of Alexandria (1789–1793), naval officer for the South Potomac (1777–1789), secretary of the Potomac Company (1785), and clerk for the Common Council of Alexandria (1785). Fairfax County voters thrice elected Lee and Samuel Arell as their two delegates in the Virginia House of Delegates—in 1793, 1794 and 1795 (though Arell died in that final and was replaced by
Elisha C. Dick, and both were replaced by
Charles Simms and Augustine J. Smith in 1796). President
George Washington appointed Lee the Attorney General after
William Bradford died in office. After Senate approval, Lee took office on December 10, 1795, and served until Washington left office. His successor, President
John Adams continued Lee in that position for nearly the entire Adams administration (until February 19, 1801). On February 18, 1801, Adams nominated Lee for one of 16 new circuit court judgeships created by the
Judiciary Act of 1801 (a judicial reorganization that also reduced the U.S. Supreme Court to five judges and temporarily eliminated circuit riding for justices). Although the Senate confirmed his appointment on March 3, 1801 (along with the "midnight judges" President Adams appointed as his administration ended), that judicial reorganization act was repealed on April 8, 1802 (by the
Judiciary Act of 1802). Both before and during his federal service, Lee lived in Alexandria, which was then part of the capital district. He was elected to the Alexandria City Council in 1794 and re-elected. He advocated returning the southern part of the
District of Columbia to
Virginia, which finally happened in 1847. In 1804 fellow councilors elected Lee as Alexandria's mayor, but he refused to serve, so Dr. Elisha C. Dick was selected instead. The previous year, his brother Edmund J. Lee had served as the council's recorder, and would first be elected to represent the third ward in 1805, later became the council's president (in 1810) and mayor (in 1815). Lee had inherited Leesylvania plantation from his father, although his mother Lucy was entitled to live there for the rest of her life (which ended in 1792), but to ease financial problems (probably related to investments of or with his brother Light-Horse Harry Lee), Charles Lee mortgaged it to his cousin William Lee, and the residence burned down, so eventually the acreage was also sold. After his time as Attorney General, in addition to becoming among the most prominent trial lawyers in Northern Virginia and the District of Columbia, Lee became the port officer for the District of the
Potomac. As a private attorney Lee represented
William Marbury and other "midnight judge" appointees of President Adams in
Marbury v. Madison, the landmark case against the Jefferson administration for unfulfilled political appointments. Simultaneously, Lee defended Hugh Stuart in
Stuart v. Laird. Lee also defended former vice president
Aaron Burr in his famous treason trial. Most members of the Lee family operated plantations using enslaved labor. Charles Lee owned two slaves in Alexandria in 1787, and either he or a man of the same common name owned slaves in several Tidewater Virginia counties where his ancestors had plantations. ==Death and legacy==
