A Testamentary trust is written into a will and is set into motion by the court after the will reaches a certain point of execution. It is used only after the death of the person whose estate it represents. It is possible to use a testamentary trust to fund many of the deferred gift options discussed elsewhere in these pages. In that manner, the options are referred to as a testamentary charitable gift annuity, a testamentary charitable remainder trust, or a testamentary charitable lead trust.
