Will vs. Trust: Differences, Costs & How to Choose
A will and a trust are both estate-planning tools, but they do different jobs. A last will and testament takes effect only at your death and must be validated by a court through probate, whereas a revocable living trust is created during your life and can hold your assets, manage them if you become incapacitated, and pass them to heirs without probate. “Should I use a will or a trust?” is the most common estate-planning question, and the usual answer is “both.” This guide compares them on the factors that actually matter — probate, cost, privacy, incapacity, and estate tax — and cites the authorities behind each point.
Key takeaways
- A will works only after you die and must be probated by a court; a funded living trust works the moment you sign it and can manage your affairs if you become incapacitated.
- A will is the only document that can name a legal guardian for your minor children — a trust cannot.
- A revocable living trust avoids probate and stays private, but only if you “fund” it by retitling assets into the trust’s name.
- Neither a basic will nor a revocable trust reduces federal estate tax — the 2026 exemption is $15,000,000 per person; only an irrevocable trust can move assets outside your taxable estate.
- For most families with meaningful assets, the answer is both: a pour-over will plus a funded revocable living trust, coordinated with beneficiary designations.
The one-sentence difference
A last will and testament is a document that takes effect only at your death and must be validated by a court through probate. A revocable living trust is a legal arrangement you create during your life that can hold your assets, manage them if you become incapacitated, and distribute them after death — typically without probate. The American Bar Association notes that, unlike a will, a living trust “can also … authorize the trustee to manage the property and use it for your benefit … if you should become incapacitated, thereby avoiding the appointment of a guardian.” Source: American Bar Association — Revocable Trusts
What a will does — and the job only a will can do
A will names an executor (sometimes called a personal representative) to settle your affairs, directs who gets your property, and — critically — names a legal guardian for your minor children. Most estate plans use both documents, and many use them together rather than choosing one. According to the ABA, only a will can designate who raises your children: “One thing only a will can do is name a legal guardian for your minor children. A trust can manage money on a child’s behalf, but it cannot designate who raises them.” Source: American Bar Association
To be valid, most states require a will to be signed in front of two disinterested witnesses who do not stand to inherit. A will does nothing while you are alive, and even after death it does not work on its own — a court must probate it. Source: LegalClarity (citing the American Bar Association)
What a trust does — and why people choose one
A revocable living trust lets you stay in control: you can change beneficiaries, add or remove assets, or dissolve it entirely while you are competent. The big advantages are probate avoidance, privacy, incapacity planning, and easier handling of out-of-state property. The ABA explains that a living trust “can help you avoid probate, which may not always be necessary depending on the cost and complexity of probate in your estate,” and that it lets a successor trustee manage your assets if you become ill or disabled.

For real estate owned in more than one state, a will generally requires a separate probate in each state, while a funded trust avoids that. A living trust is also private: once a will is filed with the court it becomes public record, but a trust’s terms are not. Source: Living Life Resources (citing the American Bar Association)
Do trusts avoid estate tax? (The myth to unlearn)
A common misconception is that a revocable living trust reduces federal estate tax. It does not. Because you can revoke or amend it, the law still counts those assets as yours, so they remain in your taxable estate. The ABA is explicit: “These trusts do not help you avoid estate tax because your power to revoke or amend them causes them to continue to be includable in your estate.” Source: American Bar Association — Revocable Trusts
For 2026, the federal estate tax exemption is $15,000,000 per person (indexed for inflation beginning in 2027 under the One Big Beautiful Bill Act). Assets inside a revocable trust are still counted toward that same exemption. Only an irrevocable trust — where you give up control — can move assets outside your taxable estate, and that is an advanced strategy for larger estates.

Cost and complexity: which is cheaper?
A will is usually cheaper to draft. Industry guidance collected by Savvy Senior suggests you can expect to pay roughly $200 to $1,000 for a will prepared by an attorney, with do-it-yourself options costing less. A trust costs more upfront because it must be drafted and then “funded” by retitling assets into it. Source: Savvy Senior / Nolo guidance
The trade-off is probate. Probate commonly costs between 3% and 7% of the gross estate value, according to the American Bar Association, and a living trust eliminates that cost for the assets it holds. On a $500,000 estate, that 3–7% range equals $15,000 to $35,000 in fees before heirs receive anything. Source: Will & Trust Maker (citing the American Bar Association)
The funding trap: a trust only works if you fund it
Creating a trust is step one; retitling your home, bank accounts, and investments into the trust’s name is step two. If you forget, those assets fall outside the trust and may still need probate. The standard fix is a “pour-over” will that catches anything left outside the trust so it still follows your plan. The ABA recommends most people use a will and a trust together: a pour-over will as a safety net and the trust for privacy, incapacity planning, and probate avoidance.

Wills vs. trusts at a glance
| Factor | Will | Revocable living trust |
|---|---|---|
| When it takes effect | Only at death, after court probate | The moment it is signed and funded; continues during incapacity |
| Probate | Required — court-supervised, often costing 3–7% of the estate | Assets titled in the trust bypass probate |
| Privacy | Becomes public record once filed | Terms generally stay private |
| Guardian for minor children | Yes — only a will can name one | No — a trust cannot designate a guardian |
| Management if incapacitated | None — a will is inert while you are alive | A successor trustee can step in |
| Typical setup cost | Roughly $200–$1,000 with an attorney | More — drafting plus funding by retitling assets |
| Federal estate tax | No reduction; 2026 exemption is $15M per person | No reduction (revocable); an irrevocable trust can reduce it |
Which should you choose?
Choose at least a will if you have minor children (to name a guardian), a modest estate, or simply want a baseline plan. Choose a trust if you own real estate (especially in more than one state), want to avoid probate, care about privacy, or are concerned about incapacity. For most families with meaningful assets, the answer is both: a pour-over will plus a funded revocable living trust, coordinated with beneficiary designations on retirement accounts and life insurance. Because trust and will formalities vary by state, confirm the documents with a licensed estate attorney in your state.
