Most people have heard they need "a will" or "a trust" — but few understand the real differences, or when one is more appropriate than the other. The short version: both transfer assets at death, but a will goes through probate court and a trust doesn't. The longer version is more nuanced.
What a Will Does
A will (also called a last will and testament) is a legal document that directs how your assets should be distributed after your death. It can also:
- Name a guardian for minor children (critical — a trust cannot do this)
- Name an executor to administer your estate
- Specify funeral and burial wishes
- Establish testamentary trusts for minor beneficiaries
A will goes into effect only at death. It must be filed with the probate court, which validates it, supervises the administration process, and oversees distribution to beneficiaries. This process takes time (typically 6–18 months), costs money (3–8% of estate value in attorney and court fees), and is public (probate records are accessible to anyone).
Importantly: a will does not control all of your assets. Assets with named beneficiaries (life insurance, retirement accounts, bank accounts with POD designations), jointly owned property, and assets held in a trust all pass outside your will regardless of what it says.
What a Trust Does
A trust is a legal arrangement in which you (the grantor) transfer legal ownership of assets to a trustee, to be managed and distributed according to the trust's terms for the benefit of beneficiaries.
A revocable living trust — the most common type used for estate planning — lets you:
- Serve as your own trustee during your lifetime (full control)
- Revoke or modify the trust at any time
- Name a successor trustee who takes over when you die or become incapacitated
- Distribute assets according to your instructions — without probate, without court involvement, without public record
Assets held in the trust at your death pass to your beneficiaries through the trust — typically in weeks, not months — without probate. See our full guide to living trusts.

| Goes through probate | Yes | No |
| Becomes public record | Yes | No |
| Timeline to distribute assets | 6–18+ months | Weeks |
| Names guardian for minor children | Yes | No (will still needed) |
| Controls assets during incapacity | No | Yes |
| Requires retitling assets | No | Yes (critical) |
| Typical cost | $150–$600 | $1,000–$3,000+ |
| Handles out-of-state property | Requires separate probate per state | All handled by one trust |
| Asset protection from creditors | No | No (revocable) |
| Reduces estate taxes | No | No (revocable) |
A Critical Point: Wills Still Often Needed Alongside Trusts
Even if you create a living trust, most estate planning attorneys recommend also having a simple "pour-over will." Here's why:
- A trust only controls assets that are legally titled in the trust's name. If you own an asset at death that was never transferred into the trust, it's not covered by the trust.
- A pour-over will catches these stray assets and "pours" them into the trust to be distributed according to the trust's terms — even though they'll go through probate first.
- A will names guardians for minor children. A trust cannot do this. If you have children, you need a will for this purpose alone.
The estate plan for most people with significant assets looks like: trust + pour-over will + powers of attorney + beneficiary designations. Not trust or will — trust and will.
When a Will Alone Is Sufficient
A will, combined with beneficiary designations and joint ownership, can be adequate for:
- People with modest estates whose main assets are retirement accounts and life insurance (which pass by beneficiary designation, not through the will)
- Renters with no real estate
- People in states with simple, inexpensive probate
- Young people just starting to build assets (get a will now; add a trust later as assets grow)
- People whose primary estate planning need is naming a guardian for children
When a Trust Makes Sense
A revocable living trust is worth the extra cost when:
- You own real estate (especially in states with expensive probate, like California)
- You own property in more than one state (without a trust, probate is required in each state)
- You have a blended family or complex family circumstances
- You have a beneficiary with special needs (a special needs trust preserves eligibility for government benefits)
- You want to provide ongoing management of assets for a beneficiary who isn't ready to receive a large sum outright
- Privacy matters to you (probate is public; trust administration is not)
- You want continuity during incapacity (a trust works when you're incapacitated, not just after death)
Irrevocable Trusts: A Different Category
This guide has focused on revocable living trusts — but irrevocable trusts are different. Irrevocable trusts permanently transfer ownership of assets to the trust; you give up control in exchange for benefits: asset protection from creditors, estate tax reduction, Medicaid planning. Common types: irrevocable life insurance trusts (ILITs), special needs trusts, Medicaid asset protection trusts, charitable remainder trusts. These require specialized legal advice and are used for specific circumstances, not general estate planning.
The Bottom Line
If you own real estate or have assets over $100,000–$150,000 (check your state's probate threshold), a living trust is usually worth it. If you're early in asset-building or rent and have named beneficiaries on your accounts, a will is a reasonable start. Either way: have something. An estimated 60–70% of American adults have no will at all — the default is that the state decides for you.
