Advowson n. (Eng. Law) The right of presenting to a vacant benefice or living in the church. (Originally, the relation of a patron (advocatus) or protector of a benefice, and thus privileged to nominate or present to it.) Note: The benefices of the Church of England are in every case subjects of presentation. They are nearly 12,000 in number; the advowson of more than half of them belongs to private persons, and of the remainder to the crown, bishops, deans and chapters, universities, and colleges.
