Presumption of priestly descent

In Judaism, the presumption of priestly descent is the presumption that a Jewish man is a priest (kohen), based not on genealogical records of descent from Aaron or on Jewish court rulings, but rather by observation of his priestly behavior as recognized by his peers and community. Such an individual is called a kohen muhzak (presumed kohen or status-quo kohen; Hebrew: כהן מוחזק, from חזק).
