does holding a fee simple estate mean that they own the land absolutely
The concept of a ``fee'' has its origins in feudalism. William Blackstone defined fee simple as the estate in land that a person has when the lands are given to him and his heirs absolutely, without any end or limit put to his estate. Land held in fee simple can be conveyed to whomsoever its owner pleases; it can also be mortgaged or put up as security. Owners of real property in fee simple have the privilege of interest in the property during their lifetime and typically have a say in determining who gets to own an interest in the property after their death.
