An immediate, fixed right to present or future enjoyment of property that is not subject to a condition precedent (other than the passage of time). The holder of a vested interest has a legally protected right that cannot be defeated, though actual possession or enjoyment may be postponed to a future time.
A vested interest is a guaranteed right to property, even if you can't have it yet. Once your interest is vested, nobody can take it away—though you might have to wait to actually receive it.

"Grandma's trust gives each grandchild $50,000 at age 25, with no other conditions. My 10-year-old daughter has a vested interest now—it's guaranteed hers. If she dies before 25, her estate gets it. Compare that to 'if she graduates college'—that would be contingent, not vested."
⚖️ Compare: Vested vs Contingent Interest
Guaranteed right. Only time delays it. Passes to heirs if holder dies. Cannot be defeated.
Conditional right. Depends on event occurring. Lost if condition not met. Can be defeated.
💡 Did you know?
The distinction between vested and contingent interests matters enormously if a beneficiary dies before receiving property. A vested interest passes to their estate or heirs; a contingent interest often disappears. That's why "to my children who reach age 25" creates contingent interests, while "to my children, to be distributed at 25" creates vested interests.
