When a Westamerica Bank account holder passes away, the next step depends on how the accounts were set up. Accounts with beneficiary designations or trust ownership transfer outside of probate. Accounts titled solely in the deceased's name require the estate's legal representative to work with Westamerica Bank's Westamerica Bank Investment Management and Trust Services (1-800-848-1088) to access and distribute the funds.
Westamerica Bank offers an online claims portal that makes the initial filing process more straightforward. Survivors can also initiate claims by phone or by mailing documentation directly.

Delays are almost always caused by incomplete paperwork—gathering all required documents before filing the initial claim helps avoid back-and-forth.
Documentation required by Westamerica Bank includes Certified copy of the death certificate, Valid government-issued photo ID for the claimant (beneficiary, executor, or administrator), and Account information for the deceased (account numbers if available), along with additional paperwork that varies by account type. All death certificates and court documents must be certified copies.

POD accounts bypass the probate process and pass directly to the named beneficiary.
Visit any Westamerica Bank branch with a valid government-issued photo ID and request to add or update POD (Payable on Death) beneficiary designations. You can also call 1-800-848-1088 (available 5 am to midnight, 7 days a week) to request the appropriate form by mail. Provide each beneficiary's full legal name, date of birth, Social Security number, relationship, and allocation percentages. Trusts named as beneficiaries may require a copy of the Certification of Trust.
Under California Probate Code Section 13100, estates with a gross value of $208,850 or less (for deaths on or after April 1, 2025) may qualify for the Small Estate Affidavit process, which allows heirs to claim account funds without full probate. This inflation-adjusted figure is set by Judicial Council form DE-300 and is scheduled to next adjust on April 1, 2028. Visit a Westamerica Bank branch with a certified copy of the death certificate, your government-issued photo ID, and the Small Estate Affidavit to begin the claim process.
