Do I Need a Will if I Have a Trust?
Yes. Even with a living trust you still need a will. A pour-over will catches any assets you did not transfer into the trust and sends them to it, and a will is the only document where you can name a guardian for minor children. The two work together, not as substitutes.
A living trust is a powerful tool, but it does not make a will unnecessary. The two documents do different jobs, and a complete estate plan almost always includes both. The most common misunderstanding is that creating a trust means you are fully covered; in practice, a trust only controls the assets you actually transfer into it, and it cannot do certain things a will can.
The reason most people with a trust still need a will comes down to two gaps a trust leaves open: assets that never made it into the trust, and naming a guardian for minor children. A will closes both. Below, here is exactly how they fit together. For the bigger comparison, see our guide on will vs living trust.
The Pour-Over Will
A trust only governs property that has been formally transferred into it, a step called “funding.” In real life, people miss assets: a bank account opened after the trust was created, a car, a recent inheritance, or simply something they forgot to retitle. Any asset left outside the trust at your death is not controlled by the trust.
That is where a pour-over will comes in. It is a short will used alongside a living trust that says, in effect, “anything I left outside my trust should be transferred into it.” It acts as a safety net, sweeping stray assets into the trust so they are ultimately distributed under the trust’s terms rather than under state default rules. To understand the funding step the pour-over will backstops, see how to set up a living trust.
A pour-over will does not avoid probate for the assets it catches. Anything that passes through it must go through probate first. The way to keep assets out of probate is to fund the trust fully while you are alive, so the pour-over will rarely has to do anything.
Naming a Guardian
This is the gap that surprises parents most. You can only name a legal guardian for your minor children in a will, never in a trust. A trust manages money and property; it has no power to decide who raises your children. If you have a trust but no will, and both parents die, a court chooses the guardian with no guidance from you.
For this reason alone, every parent of young children needs a will, regardless of how complete their trust is. If you want to set aside funds for those children, the trust handles the money while the will handles the guardianship, another example of the two documents working as a pair. Our guide on estate planning for parents with minor children covers this in depth.
What Each Document Does
It helps to see the division of labor side by side.
| Task | Will | Living trust |
|---|---|---|
| Names a guardian for kids | Yes | No |
| Distributes trust assets | No | Yes |
| Catches assets left out of the trust | Yes (pour-over) | No |
| Avoids probate | No | Yes, if funded |
| Takes effect | At death | When funded, during life and after |
| Names an executor / trustee | Executor | Successor trustee |
If You Only Have a Trust
Relying on a trust with no will leaves you exposed in two ways. First, any asset you did not transfer into the trust has no instructions, and without a pour-over will it passes under your state’s intestacy laws, the same default rules that apply to people with no estate plan at all. See what happens if you die without a will for how harsh those rules can be.
Second, if you have minor children, no one you chose is named to raise them. A court decides instead. Adding a simple pour-over will solves both problems cheaply, which is why estate planners pair the two as a matter of course rather than treating them as either-or.
Frequently Asked Questions
Do I need a will if I have a trust?
Yes. Even with a living trust you still need a will. A pour-over will catches any assets you did not transfer into the trust and sends them to it, and a will is the only document where you can name a guardian for minor children. The two work together, not as substitutes.
What is a pour-over will?
A pour-over will is a short will used alongside a living trust. It directs that any assets left outside the trust at your death be transferred (poured over) into the trust, so they are distributed under the trust’s terms. It acts as a safety net for anything you forgot to fund.
Why can’t a trust name a guardian for my children?
Naming a legal guardian for minor children can only be done in a will, not a trust. A trust manages money and property; it has no authority to appoint who raises your children. That is why parents with a trust still need a will.
What happens to assets not in my trust when I die?
Assets left outside your trust do not pass under the trust automatically. With a pour-over will, they go through probate and are then transferred into the trust. Without any will, they pass under your state’s intestacy laws, which may not match your wishes.
Does a pour-over will avoid probate?
Not for the assets it covers. Anything that passes through a pour-over will must go through probate before reaching the trust. The way to avoid probate is to fund the trust fully during your life, so the pour-over will rarely has to be used.
