Cal. Probate Code - PROB 5.

in effect

Cal. Probate Code - PROB § 4300. Section 4300.

A third person shall accord an attorney-in-fact acting pursuant to the provisions of a power of attorney the same rights and privileges that would be accorded the principal if the principal were personally present and seeking to act. However, a third person is not required to honor the attorney-in-fact’s authority or conduct business with the attorney-in-fact if the principal cannot require the third person to act or conduct business in the same circumstances.

Cal. Probate Code - PROB § 4301. Section 4301.

A third person may rely on, contract with, and deal with an attorney-in-fact with respect to the subjects and purposes encompassed or expressed in the power of attorney without regard to whether the power of attorney expressly authorizes the specific act, transaction, or decision by the attorney-in-fact.

Cal. Probate Code - PROB § 4302. Section 4302.

When requested to engage in transactions with an attorney-in-fact, a third person, before incurring any duty to comply with the power of attorney, may require the attorney-in-fact to provide identification, specimens of the signatures of the principal and the attorney-in-fact, and any other information reasonably necessary or appropriate to identify the principal and the attorney-in-fact and to facilitate the actions of the third person in transacting business with the attorney-in-fact. A third person may require an attorney-in-fact to provide the current and permanent residence addresses of the principal before agreeing to engage in a transaction with the attorney-in-fact.

Cal. Probate Code - PROB § 4303. Section 4303.

(a) A third person who acts in good faith reliance on a power of attorney is not liable to the principal or to any other person for so acting if all of the following requirements are satisfied: (1) The power of attorney is presented to the third person by the attorney-in-fact designated in the power of attorney. (2) The power of attorney appears on its face to be valid. (3) The power of attorney includes a notary public’s certificate of acknowledgment or is signed by two witnesses. (b) Nothing in this section is intended to create an implication that a third person is liable for acting in reliance on a power of attorney under circumstances where the requirements of subdivision (a) are not satisfied. Nothing in this section affects any immunity that may otherwise exist apart from this section.

Cal. Probate Code - PROB § 4304. Section 4304.

(a) The death of a principal who has executed a power of attorney, whether durable or nondurable, does not revoke or terminate the agency as to the attorney-in-fact or a third person who, without actual knowledge of the principal’s death, acts in good faith under the power of attorney. Any action so taken, unless otherwise invalid or unenforceable, binds the principal’s successors in interest. (b) The incapacity of a principal who has previously executed a nondurable power of attorney does not revoke or terminate the agency as to the attorney-in-fact or a third person who, without actual knowledge of the incapacity of the principal, acts in good faith under the power of attorney. Any action so taken, unless otherwise invalid or unenforceable, binds the principal and the principal’s successors in interest.

Cal. Probate Code - PROB § 4305. Section 4305.

(a) As to acts undertaken in good faith reliance thereon, an affidavit executed by the attorney-in-fact under a power of attorney, whether durable or nondurable, stating that, at the time of the exercise of the power, the attorney-in-fact did not have actual knowledge of the termination of the power of attorney or the attorney-in-fact’s authority by revocation or of the principal’s death or incapacity is conclusive proof of the nonrevocation or nontermination of the power at that time. If the exercise of the power of attorney requires execution and delivery of any instrument that is recordable, the affidavit when authenticated for record is likewise recordable. (b) This section does not affect any provision in a power of attorney for its termination by expiration of time or occurrence of an event other than express revocation or a change in the principal’s capacity.

Cal. Probate Code - PROB § 4306. Section 4306.

(a) If an attorney-in-fact furnishes an affidavit pursuant to Section 4305, whether voluntarily or on demand, a third person dealing with the attorney-in-fact who refuses to accept the exercise of the attorney-in-fact’s authority referred to in the affidavit is liable for attorney’s fees incurred in an action or proceeding necessary to confirm the attorney-in-fact’s qualifications or authority, unless the court determines that the third person believed in good faith that the attorney-in-fact was not qualified or was attempting to exceed or improperly exercise the attorney-in-fact’s authority. (b) The failure of a third person to demand an affidavit pursuant to Section 4305 does not affect the protection provided the third person by this chapter, and no inference as to whether a third person has acted in good faith may be drawn from the failure to demand an affidavit from the attorney-in-fact.

Cal. Probate Code - PROB § 4307. Section 4307.

(a) A copy of a power of attorney certified under this section has the same force and effect as the original power of attorney. (b) A copy of a power of attorney may be certified by any of the following: (1) An attorney authorized to practice law in this state. (2) A notary public in this state. (3) An official of a state or of a political subdivision who is authorized to make certifications. (c) The certification shall state that the certifying person has examined the original power of attorney and the copy and that the copy is a true and correct copy of the original power of attorney. (d) Nothing in this section is intended to create an implication that a third person may be liable for acting in good faith reliance on a copy of a power of attorney that has not been certified under this section.

Cal. Probate Code - PROB § 4308. Section 4308.

(a) A third person who conducts activities through employees is not charged under this chapter with actual knowledge of any fact relating to a power of attorney, nor of a change in the authority of an attorney-in-fact, unless both of the following requirements are satisfied: (1) The information is received at a home office or a place where there is an employee with responsibility to act on the information. (2) The employee has a reasonable time in which to act on the information using the procedure and facilities that are available to the third person in the regular course of its operations. (b) Knowledge of an employee in one branch or office of an entity that conducts business through branches or multiple offices is not attributable to an employee in another branch or office.

Cal. Probate Code - PROB § 4309. Section 4309.

Nothing in this chapter requires a third person to engage in any transaction with an attorney-in-fact if the attorney-in-fact has previously breached any agreement with the third person.

Cal. Probate Code - PROB § 4310. Section 4310.

Without limiting the generality of Section 4300, nothing in this chapter requires a financial institution to open a deposit account for a principal at the request of an attorney-in-fact if the principal is not currently a depositor of the financial institution or to make a loan to the attorney-in-fact on the principal’s behalf if the principal is not currently a borrower of the financial institution.
