An Inter Vivos Trust is one created by a living person for the benefit of another person. Also known as a living trust, this trust has a duration that is determined at the trust's creation and can entail the distribution of assets to the beneficiary during or after the trustor's lifetime. A parent who sets up an education fund for a child's college education is an example of an Inter Vivos Trust.
The opposite of an Inter Vivos trust is a testamentary trust, which goes into effect upon the death of the trustor.
