In law, vesting is the point in time when the rights and interests arising from legal ownership of a property is acquired by some person. Vesting creates an immediately secured right of present or future deployment. One has a vested right to an asset that cannot be taken away by any third party, even though one may not yet possess the asset. When the right, interest, or title to the present or future possession of a legal estate can be transferred to any other party, it is termed a vested interest. The concept can arise in any number of contexts, but the most common are inheritance law and retirement plan law. In real estate, to vest is to create an entitlement to a privilege or a right. For example, one may cross someone else's property regularly and unrestrictedly for several years, and one's right to an easement becomes vested. The original owner still retains the possession, but can no longer prevent the other party from crossing. Inheritance Some bequests do not vest immediately upon death of the testator. For example, many wills specify that an heir who dies within a set period (such as 60 days) is not to inherit, and further specify how the corresponding share is to be distributed. This is generally done to obviate disputes over the precise time of death, and to avoid paying taxes twice in rapid succession should multiple members of a family die in the wake of a disaster. Such a bequest does not vest until the expiration of the specified period, because the actual heir cannot be determined with certainty. It is also possible to give a person, A, a life interest in a property, with the remainder to go to another person or persons, B. If the beneficiary of the remainder cannot yet be known, then the remainder is said not to have vested, and the remainder is said to be contingent. This may happen with entailed estates, or when property is left in trust to care for a child or relative without heirs. (See trust law for details). Employment Retirement plans Vesting is an issue in conjunction with employer contributions to an employee stock option plan, deferred compensation plan, or to a retirement plan such as a 401(k), annuity or pension plan. Once a retirement plan is fully vested, the employee has an absolute right to the entire amount of
