Short answer
A will states what a person wants to happen to their property after death; a trust arranges for property to be held for another’s benefit. They are not mutually exclusive: a will can direct property into a trust. These California court sources explain the distinction, but do not establish nationwide administration rules. 1 2

| Question | Will | Trust |
|---|---|---|
| Core function? | States wishes for property after death | Holds property for another’s benefit |
| Timing? | Addresses disposition after death | Can be created during life or included in a will |
| Administrative role? | Executor named in will and appointed by court | Trustee receives property with directions for its use |
| Court connection? | California glossary describes court-appointed executor | San Francisco court describes trust supervision |
These contrasts reflect the supplied California court descriptions. 1 2
What each thing is
The defining feature of a will is its expression of wishes about property after death. The defining feature of a trust is the holding arrangement: someone holds property for someone else’s benefit. A living trust is one type of trust, not another name for the entire category. 1
Key differences
The control mechanisms differ. A will states the intended disposition of property; a trust places property under an arrangement for another’s benefit. The San Francisco court describes living-trust creators putting property into the trust during life. It also describes wills directing estate property to trustees for specified uses. Creation timing therefore depends on the trust type. 1 2
How to tell them apart
Ask what the document or arrangement does: does it state wishes for property after death, or provide for property to be held for another’s benefit? Then look for directions to a trustee. The limit is important: both features can appear in one will, so a document’s title alone does not resolve whether it also establishes a trust. 1 2
Where they overlap
Both concepts concern property and who receives its benefit. Their clearest overlap is a will directing all or part of an estate to a trustee, along with instructions for using it. In the San Francisco court’s terminology, a trust that is part of a will is a testamentary trust. 2
Edge cases
Court involvement does not cleanly separate them. The California glossary describes a court-appointed executor, while the San Francisco court explains that trusts can also come under probate-court supervision. For example, a beneficiary can petition for review and an accounting of asset handling. Trust supervision is therefore not the same question as whether property passes through probate. 1 2
Why the distinction exists
The distinction separates instructions about disposition from an arrangement for holding and administering property. Probate, as California Courts describes it, also addresses debts and the deceased person’s financial affairs—not just inheritance wishes. A trust’s defining feature instead concerns holding property for another’s benefit. These are different organizing functions, even when combined. 1
Common misconceptions
A trust is not necessarily a living trust: the San Francisco court lists testamentary and special needs trusts too. Nor does the word “trust” mean courts have no role. Its discussion of beneficiary petitions directly shows a route to court supervision; the supplied excerpts do not establish a blanket probate-avoidance rule. 2
Examples
Hypothetical case one: a person creates an arrangement during life and puts property into it for another’s benefit. That fits the sources’ living-trust description. Case two: a will directs part of an estate to a trustee with instructions for its use. That combines a will with a testamentary trust rather than requiring a choice between them. 1 2
