Vesting: property rights become fixed and enforceable when they accrue, distinct from mere contingent expectancies. Vesting denotes conferral or acquisition of a legally fixed right to present or future enjoyment of property or authority; it creates a settled, accrued, and enforceable interest distinguishable from mere expectancy. Vested interests are not contingent on conditions precedent and are not defeasible in the same way as future or contingent interests. A vesting order is a statutory device transferring property to become vested without conveyance.
