Item 4.01  Changes in Registrant's Certifying Accountant.

On July l3, 2005, the Audit Committee of the Board of Directors of Pacific
Capital Bancorp (the "Company") appointed Ernst & Young LLP ("E&Y") as the
Company's independent registered public accounting firm for the year ending
December 31, 2005. The decision came after the Audit Committee adopted in March
2005 a policy to solicit proposals for the auditing engagement at least every
three years. The Committee received proposals for the engagement from three
firms including E&Y. Based on these proposals, the Committee has selected E&Y
which has concluded its client acceptance procedures.
