US-CaliforniaWhat is a pour-over will and how does it work with a trust?
A pour-over will is a last will and testament that 'pours over' any assets not already in a living trust into that trust upon the person's death, ensuring all property is distributed according to the trust’s terms.
What the Law Says
California law recognizes pour-over wills as valid instruments that direct assets not already in a trust to be transferred into it after death. The will must be valid under California probate law, and the trust must exist (or be executed concurrently) for the pour-over provision to be enforceable.
Under California Probate Code § 15000, a pour-over will is authorized when it devises property to a trust that is identified in the will and either exists at the time of the testator’s death or is created by the will itself. This allows the will to act as a safety net for assets accidentally left out of the trust during lifetime planning.
The trust receiving the poured-over assets must be sufficiently described in the will so that its identity is clear — vague references are insufficient. Also, the trust must be valid under California law, meaning it complies with formalities for revocable or irrevocable trusts under Probate Code §§ 15000–15100.
Importantly, pour-over provisions do not avoid probate for assets passing through the will — only assets already titled in the trust avoid probate. Assets flowing through the pour-over will still go through probate unless they qualify for simplified procedures (e.g., small estate affidavit under Probate Code § 13100 for estates under $184,500 as of 2024).
Statutory TextA will may devise property to a trust that is identified in the will and that is in existence at the time of the testator’s death or that is created by the will.

Statutory TextA trust may be created by will. A trust created by will is not subject to the requirements of Section 15001, but is subject to the requirements of Chapter 2 (commencing with Section 15040) of Part 2 of Division 3.

What to Do
Execute a valid California will containing a clear pour-over clause naming your existing or concurrently executed trust.
Ensure your trust document is signed, dated, and properly funded (i.e., assets retitled or beneficiary-designated to the trust).
Review beneficiary designations on retirement accounts and life insurance — these pass outside both will and trust unless the trust is named as beneficiary.
File the pour-over will with the probate court within 30 days of death (Probate Code § 8200), even if most assets are in trust.
Work with an attorney to confirm the trust is properly referenced in the will (e.g., name, date, and trustee) to satisfy § 15000’s identification requirement.
