Juridic persons in the Church are either aggregates of persons (universitates personarum) or aggregates of things (universitates rerum). A juridic person – established in accordance with the Church law – is perpetual by its nature. A juridic person in the Church is extinguished if it is legitimately suppressed by competent authority or ipso iure has ceased to act for a hundred years. Upon the extinction of a public juridic person, the allocation of its goods, patrimonial rights, and obligations is governed by law and its statutes. However, the will of the founders and donors and acquired right must always be preserved. If the law and statutes give no indication, they go to the juridic person immediately superior.
