What Is a Testamentary Trust? Here’s How It Works in Missouri
A Testamentary Trust is a tool built for a very specific situation. People tend to be less familiar with this type of Trust – as opposed to Revocable Living Trusts or Irrevocable Trusts, which seem to get a lot more mention and use.
A Testamentary Trust is a Trust you create inside your Last Will and Testament (hence the name “Testamentary Trust”). Unlike other Trusts, a Testamentary Trust is not a separate or standalone document, and not something that exists while you’re alive. It only comes into being if (1) you pass away, and (2) your Will goes through probate, which is the Court process that validates the Will and oversees how the estate gets distributed.
Compare that to a Living Trust (also called a “Revocable Trust” or “Revocable Living Trust”). A Living Trust is a standalone document that exists the moment you sign it. However, a Testamentary Trust doesn’t exist at all until you’re gone and a judge has said your Will is valid.
For example: Say you’ve got two kids, and you want to leave them each a share of your estate. You’re just not thrilled about the idea of handing an 18-year-old a lump sum with no strings attached. Also, you don’t necessarily want to go through the effort of creating a standalone, Revocable Living Trust, and “funding” the Trust (changing the titling/ beneficiary designations to some or all of your assets). So you simply put some Testamentary Trust provisions in your Will, stating that if your child is under age 25 at the time you die, that this Testamentary Trust will be established upon your death. That’s the exact situation a Testamentary Trust is built for.
Why Choose A Testamentary Trust?
Most people who ask us about Testamentary Trusts have one thing in common: they want to control how and when someone receives money, not just whether they receive it. That usually comes down to one of a few situations.
The most common situation where we see a Testamentary Trust utilized is by young couples, with young children, who are in the “acquisition phase”. Life is going well, the careers are on the upward trend, and they simply want to set up some bare-bones rules about who would hold the money, and how it would be used, if they passed away but their children survived. They don’t want to go to the time and expense to set up a full revocable trust, because after all, they are young and probably nothing is going to happen to them. However, they want something basic in the background, yet not overly basic.
Is A Testamentary Trust Revocable Or Irrevocable?
Both, in a sense, and that’s what trips people up. While you’re alive, nothing about it is locked in. Your Will — and the Trust terms written inside it — can be changed any time you want, as many times as you want, right up until you pass away.
Once you die and the Trust comes into existence, that changes. At that point it’s irrevocable. Nobody, including the Trustee you named, gets to rewrite the terms.
The Trade-Off: Probate
Here’s the part people don’t love. Because a Testamentary Trust is created through your Will, your estate has to go through probate before the Trust is even funded. That means Probate Court involvement, Court timelines, and Court costs. A Living Trust is built specifically to skip that process.
So why would anyone pick a Testamentary Trust over a Living Trust? Usually cost and simplicity while you’re alive. A Living Trust takes more upfront work to set up and fund. A Testamentary Trust rides inside a Will you’re already creating.
The Language In Your Will Matters
Honestly, this is one of the places we see the most expensive mistakes. Missouri Courts see plenty of homemade Wills that try to create a Trust with vague or incomplete language: no clear Trustee powers, no real distribution instructions, no backup plan if the named Trustee can’t serve.
When that happens, the Trust either fails outright or ends up in front of a probate judge for months while everyone argues about what you actually meant. The cost of fixing that in probate is almost always more than it would’ve cost to have the Trust written correctly the first time.
What This Costs, And What We Do
We quote Testamentary Trust work the same way we quote most of our estate planning — after a consultation, not before. Most of these cases land somewhere between a few hundred dollars for something straightforward and a couple thousand for something more involved, also depending on whether we do a package deal including powers of attorney and health care directives, etc.
You don’t need to have all the answers walking in. Tell us who you’re trying to protect and why, and we’ll tell you honestly whether a Testamentary Trust is the right tool for your situation — sometimes it’s not, and a Living Trust or a more straightforward Will is a better fit.
Frequently Asked Questions
What is a Testamentary Trust?
A Testamentary Trust is a Trust created inside your Will. It doesn’t exist while you’re alive — it only comes into being after you pass away and your Will goes through probate.
Is a Testamentary Trust revocable or irrevocable?
Both, depending on when you’re asking. While you’re alive, you can change the terms any time because your Will itself is revocable. Once you die and the Trust is created, it becomes irrevocable.
How is a Testamentary Trust different from a Living Trust?
A Living Trust is a standalone document, exists the moment you sign and fund it, and it’s built to skip probate. A Testamentary Trust only exists after probate creates it, so your estate still goes through the Probate Court process first.
Does a Testamentary Trust avoid probate?
No. A Testamentary Trust is created through probate, not around it. If avoiding probate is your main goal, a Revocable Living Trust is usually the better fit.
Who manages a Testamentary Trust?
A Trustee you name in your Will manages it. That person is responsible for holding, investing, and distributing the assets according to the terms you set.
Can a Testamentary Trust protect a beneficiary with special needs?
It can, but it has to be drafted carefully. A poorly written Trust can actually disqualify someone from Medicaid or SSI. Most attorneys use a dedicated special needs Trust structure for this instead of a general Testamentary Trust.
Do I need an attorney to set up a Testamentary Trust in Missouri?
You’re not legally required to have one, but Missouri Courts see a steady stream of homemade Wills with vague or incomplete Trust language that fails or ends up in probate litigation. Fixing that after the fact almost always costs more than having it drafted correctly to begin with.
How much does a Testamentary Trust cost in Missouri?
It depends on how many beneficiaries and conditions are involved. We can usually give a solid quote after consultation, and most estate planning work like this runs from a few hundred dollars for something simple to a couple thousand if part of an estate planning package with powers of attorneys and health care directives, etc.
