Olive Geiger Faircloth, 83, a Washington lawyer and former assistant D.C. corporation counsel who had been active in civic affairs, died of cancer Monday at Sibley Memorial Hospital. She lived in Washington.

In later years, Mrs. Faircloth had maintained an estate law practice here, managing real estate investments.

Earlier, she had been an assistant corporation counsel from the late 1930s until 1957, when she retired from government service.

She was born n Cleveland and came to Washington with her family in 1903. She graduated from the George Washington University Law School in 1922.

She had a private law practice here until joining the child welfare division of the D.C. Board of Public Welfare in 1928, where she remained until becoming an assistant corporation counsel.

Mrs. Faircloth had served two terms as president of the Women's Bar Association. She belonged to the D.C., Federal and American Bar Associations and the National Lowyers Club.

She was the widow of Warren T. Faircloth, a Justice Department attorney, who died in 1949.

The family suggests that expressions of sympathy be in the form of contributions to the Women's Auxiliary of the Salvation Army of Washington.
