Most people who ask "should I have a will or a trust?" are really asking the wrong question. A will and a revocable living trust solve slightly different problems. Many people end up with both. The right starting point is understanding what each one actually does.
What a will does
A will is a legal document that takes effect when you die. It tells the court — and the world — who should receive your assets, who should raise your minor children, and who should manage the process of settling your estate.
A will must go through probate: the court-supervised process of validating the document, paying debts, and transferring assets to beneficiaries. Probate is public (anyone can look up what you owned and who received it), takes time (typically 6 to 18 months), and costs money (court fees, attorney fees, executor fees).
A will also does something a trust cannot: name a guardian for minor children. This is one of the most important reasons to have a will even if you also have a trust.
What a revocable living trust does
A revocable living trust is a legal entity you create during your lifetime. You transfer assets into the trust — your house, your bank accounts, your investments. You remain the trustee while you're alive, so you keep full control. When you die, the assets inside the trust transfer directly to your named beneficiaries without going through probate.
Because the trust controls the assets (not your estate), probate is skipped entirely for those assets. Distribution can happen in days or weeks rather than months. It's also private — trust distributions don't appear in public court records.
A trust can also include instructions for disability: if you become incapacitated, a successor trustee you named takes over management of your assets without court involvement.
The key differences
Probate: A will goes through probate. A trust avoids it.
Privacy: A will becomes a public record. A trust stays private.
Cost and complexity: A will is simpler and cheaper to create. A trust requires funding — you must actually re-title assets into the trust for it to work. An unfunded trust is worth nothing.
Guardianship: Only a will can name a guardian for minor children. A trust cannot.
Timing: A will only takes effect at death. A trust is active during your lifetime and can handle incapacity.
Cost to administer: A will incurs probate costs. A trust generally costs less to administer after death (but more to set up).
Who benefits most from a trust
A revocable living trust tends to make the most sense if:
— You own real estate in more than one state (probate must be opened in each state where you own property) — Your estate is large or complex — You value privacy and don't want your assets and beneficiaries listed in a public court record — You want your affairs managed seamlessly if you become incapacitated — You want assets distributed quickly, without waiting for probate to close
A trust is generally less necessary if your estate is modest, all your significant assets already have beneficiary designations (IRAs, life insurance, 401(k)s), and you're comfortable with probate.
Most people should start with a will
For the majority of people — especially those earlier in life, without complex estates, or just getting started — a will is the right first step. It covers the essentials: who gets what, who raises your children, who manages the process.
A trust adds value but also adds work. You need to fund it properly, maintain it over time, and re-title assets as your situation changes. Many people create a trust and never properly fund it, which means it does nothing.
The most important thing is having something. An unfunded trust is worse than a simple will, because it creates the illusion of planning without the substance.
The pour-over will
Most people who create a trust also create a "pour-over will" — a simple will that says any assets not in the trust at your death should flow into the trust. This catches anything you forgot to transfer or acquired after creating the trust. It still goes through probate for those assets, but it keeps everything organized under one plan.
If you have a trust, you still need a will — specifically to name guardians for your children, and to catch stray assets.
