ExpropriationEn droit, l'expropriation est une opération tendant à priver, contre son gré, un propriétaire foncier de sa propriété. De nos jours, ce terme désigne le plus souvent une expropriation pour cause d'utilité publique. Des expropriations avec compensation financière sont généralement faites pour la réalisation de projets d'infrastructure : routes et autoroutes, aéroports, etc. Le problème des compensations est une question litigieuse, et le montant doit souvent être tranché par les tribunaux.
Fee simpleIn English law, a fee simple or fee simple absolute is an estate in land, a form of freehold ownership. A "fee" is a vested, inheritable, present possessory interest in land. A "fee simple" is real property held without limit of time (i.e., permanently) under common law, whereas the highest possible form of ownership is a "fee simple absolute," which is without limitations on the land's use (such as qualifiers or conditions that disallow certain uses of the land or subject the vested interest to termination).
Life estateIn common law and statutory law, a life estate (or life tenancy) is the ownership of immovable property for the duration of a person's life. In legal terms, it is an estate in real property that ends at death when ownership of the property may revert to the original owner, or it may pass to another person. The owner of a life estate is called a "life tenant". In the combined jurisdiction of England and Wales since 1925 a freehold estate intended to be 'held' as a life interest takes effect only as an interest enjoyed in equity, specifically as an interest in possession trust.
