One who receives property from someone who has died. While the traditional meaning includes only those who had a legal right to the deceased person's property, modern usage includes anyone who receives property from the estate of a deceased person.

A right to use another person's real estate for a specific purpose. The most common type of easement is the right to travel over another person's land, known as a right of way. In addition, property owners commonly grant easements for the placement of utility poles, utility trenches, water lines or sewer lines. The owner of property that is subject to an easement is said to be 'burdened' with the easement, because he or she is not allowed to interfere with its use. For example, if the deed to John's property permits Sue to travel across John's main road to reach her own home, John cannot do anything to block the road. On the other hand, Sue cannot do anything that exceeds the scope of her easement, such as widening the roadway.

A right to property that cannot be enforced in the present, but only at some time in the future. For example, John's will leaves his house to his sister Marian, but only after the death of his wife, Hillary. Marian has a future interest in the house.
