Wills & Trusts
Testamentary Trusts Created By The Will Itself
A testamentary trust does not exist until the will is probated, which changes how it is funded, supervised and timed compared with a trust created during life.

Not every trust is signed during someone's lifetime. A testamentary trust is written inside a will and springs into existence only when that will is admitted to probate.
How it comes into being
The will contains the full trust terms: who benefits, what the trustee may do, when distributions occur and when the trust ends.
Nothing operates while the testator is alive. The will can be revised or replaced like any other, and the trust provisions change with it.
On death the will is submitted to probate. Once admitted, the executor administers the estate and eventually transfers the designated assets to the trustee named inside it.
Why anyone would choose one
The main appeal is simplicity during life. There is no separate document to sign, no funding exercise, and no ongoing administration or tax filing before death.
It suits situations where the trust's purpose only arises at death, such as holding a share for young children who may be adults by then anyway.
For estates where probate is expected regardless, the trust adds structure without adding a proceeding that would not otherwise have happened.
The trade-off against a living trust
A testamentary trust cannot avoid probate, because probate is the event that creates it. Privacy is reduced accordingly, since the terms sit in a public filing.
Funding also waits on the estate. Where a living trust can begin supporting beneficiaries almost immediately, a testamentary trust receives assets only after administration progresses.
It provides no help with incapacity during life, which is one of the principal reasons people create revocable trusts in the first place.
Ongoing court involvement
Some jurisdictions keep testamentary trusts under continuing court supervision, requiring periodic accountings filed with the court rather than delivered privately to beneficiaries.
That supervision provides oversight but adds cost and delay, and it may persist for as long as the trust lasts, which can be decades.
Whether supervision applies, and whether it can be waived in the will, differs considerably from place to place.
Where it fits a plan
Testamentary trusts appear frequently in plans for parents of young children, where the object is holding a share until a certain age rather than long-term wealth management.
They are also common as contingency structures, taking effect only if a beneficiary is under a stated age or has a defined need at the time of death.
Probate procedure and trust supervision rules vary by jurisdiction and change. Nothing here is legal advice, and structure choices should be tested with a qualified professional.
