(ii) depending on the determination/existence of the person[s] to whom the estate is limited.
EXAMPLE:
John grants land to Jane (his sister) until she dies, and then provides that the land go to Paul’s children. Paul did not have any children at the time, so the grant [of the land to them following Jane’s death] is a contingent estate. If Paul has still no children when Jane dies, then the title [to the land] reverts back to John (who first granted it).
