Navigating the legal landscape of California can often be a journey marked by intricate details and specific requirements, particularly when it comes to notarizing Power of Attorney documents. One critical aspect of this process, however, is understanding who is eligible to serve as a witness.

This article aims to provide a comprehensive overview of the requirements and considerations for witnesses in notarized POA documents in California, ensuring that your legal documents are not only valid but effective too.

The Role of Witnesses in POA Documents

Witnesses play a pivotal role in the execution of a Power of Attorney. Their presence during the signing process affirms that the document is signed willingly and by the correct individual. In California, depending on the type of Power of Attorney, the presence of one or two witnesses might be necessary. These witnesses contribute by adding or providing an additional layer of authenticity and can help prevent future disputes regarding the document’s validity.

Power of Attorney Witness Requirements: Who Can Serve as a Witness?

Now that we know what the role of a witness is, let us take a look at the essential requirements a person must possess to qualify as a witness in the first place:

  1. Age: The primary requirement for a witness is that they must be of legal age, which is 18 years or older in California.
  2. Mental Competence: The next requirement is that potential witnesses should be mentally competent, meaning that they understand what they are witnessing and can attest to the principal’s capacity and voluntary signing of the document.
  3. Impartiality: Ideally, witnesses should be neutral parties. This means they should not have a vested interest in the POA’s contents. Family members, beneficiaries, or anyone else who might benefit from the POA are generally discouraged from acting as witnesses to avoid conflicts of interest. If not possible, select the person who is least interested in the benefits that come out of the POA.
  4. Exclusions: While some people may or may not serve as witnesses, certain individuals are completely excluded from serving as witnesses. For example, the person named as the agent in the Power of Attorney should not be a witness. Moreover, healthcare providers or employees of healthcare facilities where the principal resides are also typically excluded, especially in the case of healthcare-related POAs.

Special Considerations for Different Types of POA

As definite as the rules and regulations regarding witnesses are, there are a few special considerations that principals should be mindful of:

  1. Healthcare Power of Attorney: California law has specific guidelines on who can act as a witness when notarizing a healthcare POA that allows an agent to make medical decisions on behalf of the principal. Generally, healthcare providers or operators of community care or residential care facilities for the elderly are prohibited from serving as witnesses if they provide care to the principal.
  2. Durable Power of Attorney: For a durable POA, which remains in effect even if the principal becomes incapacitated, the witnessing requirements are similar to a general POA. However, ensuring that witnesses are completely unbiased and understand the document’s significance is crucial due to its long-term implications.

It’s important to note that legal requirements can vary based on the specifics of the situation and the type of power of attorney being executed. Hence, it’s advisable to consult with a legal professional or check the latest state guidelines to ensure compliance with all legal requirements in California.

Notarization Process and Witness Involvement

In California, notarization involves a notary public who verifies the identity of the signer, as well as the witnesses, before the process of signing the document is carried out. While the presence of a notary public adds a degree of legal authentication, having additional witnesses may still be required or recommended. Notaries in California, in particular, are trained to ensure that the signers of legal documents are doing so of their own free will and are aware of the contents of the documents.

Best Practices for Selecting Witnesses

  1. Choose Wisely: Select trustworthy witnesses who understand the importance of their role. They should be people who can be relied upon to testify about the signing if needed in the future.
  2. Documentation: Ensure that the witnesses’ names and contact details are accurately recorded in the POA document for future reference.
  3. Brief Your Witnesses: Before the signing, explain the nature of the document to the witnesses. While they don’t need to know all the details, they should be aware that they are witnessing the signing of a legal document.

Should One Ask For Proof Regarding the Attorney-in-Fact’s Authority?

When dealing with an attorney-in-fact, the individual appointed to act on behalf of someone else through a Power of Attorney (POA), it is generally advisable to ask for proof of their authority. This practice is not just a formality; it serves several important purposes.

Some of those purposes are as follows:

  1. Verifying Legal Authority: Requesting proof, typically in the form of the POA document itself, allows you to verify that the attorney-in-fact indeed has the legal authority to act on behalf of the principal (the person who granted the POA). This is crucial in ensuring that any actions taken or decisions made are legally binding and valid.
  2. Understanding Scope of Authority: Power of Attorney documents can vary greatly regarding the scope of authority granted. Some may grant broad powers, while others are very specific or limited. By reviewing the POA document carefully, you can determine the extent of the attorney-in-fact’s power, ensuring that they are acting within their designated boundaries or if they are overstepping them.
  3. Protecting All Parties Involved: Asking for proof of authority protects the principal and you and the attorney-in-fact. It ensures that all actions are transparent and within legal parameters, reducing the risk of disputes or legal complications down the line.
  4. Compliance with Legal and Organizational Policies: In many cases, especially in financial and healthcare settings, legal or organizational policies may require verification of an attorney-in-fact’s authority. Failing to adhere to these policies can result in non-compliance issues.
  5. Recency and Validity: It’s important to check that the POA document is recent and still valid. In some cases, POAs can be revoked or amended, or they might expire. Verification helps ensure that the document is current and in effect.
  6. Notarization and Witnesses: Ensure that the POA has been properly notarized and, where applicable, signed by the required number of witnesses. This step is key in validating the document.

Can an Attorney-in-Fact take an Oath or Affirmation For Someone Else?

An attorney-in-fact is the individual appointed through a Power of Attorney to act on behalf of someone else, and generally cannot take an oath or affirmation on behalf of the principal. Oaths and affirmations are deeply personal legal acts that require the direct, personal participation of the individual making them. Here are the key reasons why an attorney-in-fact cannot take an oath or affirmation for someone else.

Here are a few reasons why this is the case:

  1. Personal Nature of Oaths and Affirmations: Oaths and affirmations are solemn declarations, affirming the truth of a statement or the commitment to a duty. These acts are usually personal and cannot be delegated to another person, including an attorney-in-fact.
  2. Legal Requirements: Many legal processes that require an oath or affirmation, such as testifying in court, voting, or executing an affidavit, are based on the principle that the individual personally understands and agrees to the statement or duty. The personal presence and acknowledgment of the individual are often legally required and necessary.
  3. Limitations of POA: The powers granted through a POA have limitations. They usually cover financial, property, and certain personal matters but do not extend to acts that are considered personal, such as making an oath or affirmation.
  4. Risk of Invalidating Legal Processes: If and when an attorney-in-fact attempts to take an oath or affirmation on behalf of the principal, it could potentially invalidate the legal process or document involved since this is because such an action might be viewed as misrepresentation or fraud.
  5. Exceptional Circumstances: There may be very specific circumstances where a form of delegated authority might allow for certain types of declarations or consents, however, these are generally not the same as taking an oath itself and are governed by specific legal provisions.


Selecting the appropriate witnesses for a notarized Power of Attorney in California is a process that should be approached with diligence and understanding. By following the state’s requirements and considering the type of POA being executed, you can ensure the legal integrity and effectiveness of your document.

It is always worth remembering that the role of witnesses is not just a mere formality but a crucial step/part of the legal process in safeguarding your interests and wishes as laid out in your Power of Attorney.
