Carlyle E. Maw, 84, who had served during the Nixon and Ford administrations as the State Department legal adviser and as an undersecretary of state, died of cancer Dec. 2 at his home in Washington.

Before joining the State Department as legal adviser in 1973, he had been a partner in the New York law firm of Cravath Swaine & Moore, where his clients included Henry A. Kissinger's lawyer. After joining State, he advised Secretary of State Kissinger and was the department's chief legal adviser.

He accompanied Kissinger to the Middle East on his famous "shuttle diplomacy" trips. These resulted in the signing of a disengagement agreement between Israel and Egypt and a lessening of tensions in the Middle East.

In June 1974, Mr. Maw became undersecretary of state for coordinating security assistant programs. In that role, he was special presidential representative to the 1975 Law of the Sea conference. He left State in 1976, rejoining Cravath Swaine as head of its London office. He held that post until retiring as a partner and moving here in 1981.

Mr. Maw was a native of Provo, Utah, and was a U.S. Senate page from 1915 to 1919. He was a 1925 graduate of Brigham Young University and graduated cum laude in 1928 from Harvard University law school, where he had edited the law review.

He joined Cravath Swaine in 1928. From 1933 to 1934, he took leave of the firm to serve as chief counsel of the old Public Works Administration's housing division. He then returned to his firm and became a partner in 1939.

Mr. Maw had held a variety of bar association posts. He had headed committees of both the American and New York State bar associations and had been a vice president of the New York City Bar Association. From 1979 to 1981, he was chairman of the State Department's Public Advisory Committee on Law of the Sea. He was the author of technical works on antitrust and international law.

His wife of 50 years, the former Margot Bell, died in 1985. Survivors include two sons, Michael B. and Carlyle Jr., both of Washington; a daughter, Susan deWilde Hykin of Victoria, B.C., and five grandchildren.
