He studied law in Washington, D.C., was admitted to the bar in 1821, and returned to New Brunswick to begin his practice. He was master in court chancery in 1824, and surrogate of Middlesex County from 1831 to 1836.

He was Mayor of New Brunswick, New Jersey, from 1841 to 1842. His grandfather John Bubenheim Bayard had been elected mayor of the city in 1790.

Kirkpatrick served as a trustee of Rutgers College from 1841 to 1859. He was elected as a Democrat to the Twenty-eighth Congress, serving in office one term from March 4, 1843, to March 3, 1845. He was chairman of the Committee on Revisal and Unfinished Business.
