The document discusses different types of property ownership in real property law. There are two main categories: freehold estates and leaseholds. Freehold estates provide indefinite ownership of land and include three types: fee simple is the most complete form, providing unlimited ownership that can pass down through heirs; life estate gives ownership for the duration of the owner's life; and estate pur autre vie measures ownership by someone else's life. Leaseholds provide temporary, limited property interests through lease contracts rather than indefinite ownership.
