In the Roman Catholic Church a chancellor is the chief record-keeper of a diocese or eparchy or their equivalent. Normally a priest, sometimes a deacon or layperson, the chancellor keeps the official archives of the diocese, as a notary certifies documents, and generally manages the administrative offices (and sometimes finances and personnel) of a diocese. He may be assisted by vice-chancellors. Though he manages the paperwork and office (called the "chancery"), has no actual jurisdictional authority: the bishop of the diocese exercises decision-making authority through his judicial vicar, in judicial matters, and the vicar general for administrative matters.
In the United Methodist Church, each Annual Conference has a Conference Chancellor, who is either an active or retired lawyer or judge who serves as the Annual Conference's legal adviser and representative. While the Annual Conference will usually hire outside professional counsel in legal matters requiring legal representation, that hiring and representation is done under the supervision, and with the consent, of the Conference Chancellor.
