REVERSION.
Reversion, it hath a double acception in our Law, the one is, jus revertendi cum status possessio∣nis defecerit: and this is but an interest in the* 1.1 Land when the occupation and possession of it shall fall, and so it is commonly taken. 2. When the possession and estate which was parted for a time ceaseth, and is determined in the persons of the aliens, assignees, grantees, or their Heirs, and shall effectually return to the Donor, his heirs or assignees whence it was derived. This is the most apt and proper signification of the word, which is nomen verbale, and derived of the verb revertor, & aptè dici non potest reversio; ante∣quam revertatur in facto.
A reversion is where the residue of the estate alwaies doth continue in him that made the par∣ticular estate, or where the particular estate is derived out of his estate. Cook on Lit. l. 1. c. 2. sect. 19.
