The Borough of Medford Lakes is governed under the 1923 Municipal Manager Law form of New Jersey municipal government, one of seven municipalities (of the 565) statewide that use this form. The governing body is comprised of five members, who are elected at-large in non-partisan elections to serve four-year terms on a staggered basis, with either two or three seats up for vote in even-numbered years as part of the May municipal election. The borough council was expanded from three to five seats, with the two additional council seats added as part of the May 2010 election in which there were two seats up for a four-year term and two others for a two-year term.
