An interesting tidbit on the term Freehold from Wikipedia:
Legally all land in England, Wales, and Scotland belongs to the Crown. Freehold is ownership of an estate in land rather than the land itself. This distinction dates back to the Middle Ages and makes relatively little difference nowadays, so legal authorities often do not bother to distinguish between ownership of the land and ownership of an estate. Its effect is most notable when property becomes ownerless at which point it reverts to the monarch (as the owner of the superior interest) under a process known as
escheat.
Escheat is a
common law doctrine that transfers the
real property of a person who has died without heirs to the Crown or state. It serves to ensure that property is not left in "limbo" without recognized ownership. It originally applied to a number of situations where a legal interest in land was destroyed by
operation of law, so that the ownership of the land reverted to the immediately superior
feudal lord.
People did not have to actually die for this process to happen. It also happened upon the conviction of a felony. That is how some folks during the Salem Witch Trials got rid of their rivals. They accused them of witchcraft. Once found guilty, their property was taken.
