When the Son Makes the Call: Notarizing a Power of Attorney for a Father With Dementia in La Verne
The phone call came from a son, not his father. That detail matters more than it might seem.
He explained that his dad lived in La Verne and had been diagnosed with dementia. The family had decided it was time to get a power of attorney in place before his father’s condition progressed further. The son wanted to be named as the agent — the person legally authorized to manage his father’s financial and legal affairs when he could no longer do so on his own. He needed a dementia power of attorney notary who understood both the legal requirements and the human weight of what his family was navigating.
That call is one I receive regularly across the Inland Empire. Families in La Verne, Pomona, Claremont, Ontario, and Upland reach out when they realize the window for getting legal documents signed may be closing faster than they expected. When a parent has dementia, that window is real — and it is not always as narrow as families fear.
I am Brent with Wet Ink Notary, a California-commissioned mobile notary based in Upland. I drove to La Verne, sat down with this father and his son, and completed the notarization. This is the story of how that signing went, what I assessed before putting my seal on anything, and what families dealing with dementia and power of attorney need to understand before they call a notary.

What Families Get Wrong About Dementia and Power of Attorney
The most common misconception I encounter is this: families assume that a dementia diagnosis automatically disqualifies someone from signing a power of attorney. That is not what California law says.
Under California law, the standard for signing a power of attorney is legal capacity, not medical diagnosis. To meet that standard, a person must understand the nature of the document, the powers they are granting, who they are granting those powers to, and what effect the document will have on their affairs — all at the moment of signing.
A dementia diagnosis exists on a spectrum. Some individuals in early or moderate stages retain full legal capacity during their lucid periods. Others, particularly in later stages, may no longer meet that standard on any given day. The diagnosis itself does not make that determination — the notary’s assessment at the time of signing does.
This is why timing matters so much. Families who act early, while their loved one still has capacity during good windows of the day, have the best chance of completing a valid signing. Those who wait too long may find that no notary can ethically complete the notarization, and the only remaining option is a costly court-ordered conservatorship.
The California Probate Code sections 4120 through 4130 govern the requirements for a valid power of attorney, including the capacity standard every signer must meet.
The Assessment: What I Do Before Any Document Is Signed
When I arrived at the home in La Verne, the son met me at the door. The father was seated at the kitchen table. Before the documents came out, I did what I always do at a signing involving cognitive decline: I had a conversation.
Not about the power of attorney. About him.
My first questions were about his life, not the documents. How long had he lived in La Verne? What had he done for work? Did he have other family nearby? These are not small talk. They are a baseline assessment. Listening for orientation, coherence, and the ability to hold a thread of conversation without losing it — that is the real work happening in those first few minutes.
After a few minutes, the conversation shifted toward the documents. When I asked whether he knew why I was there, he told me his son was going to help manage his affairs. Then I asked him to explain in his own words what that meant. He described, clearly and without prompting, that his son would be able to handle his bank accounts and bills if he was not able to do it himself anymore.
That answer told me what I needed to know. He understood the nature of the document. He understood who his agent was. He understood what authority he was granting. Critically, he was not being pressured — he expressed, without hesitation, that this was what he wanted.
That is the standard. He met it.
The Three Questions Every Notary Must Answer Before Signing
California notaries are not doctors, and we do not diagnose cognitive conditions. However, before notarizing any document for a person with dementia, I need to satisfy myself on three specific questions.
Does the signer understand what they are signing?
This is the capacity question. The signer must demonstrate, in their own words, a reasonable understanding of the document’s purpose and effect. Rather than reading a definition off the page and asking whether they understood it, I ask them to explain it back to me in plain language.
Is the signer acting voluntarily?
Undue influence is a serious concern in elder signings. If a family member is coaching answers from across the room, finishing sentences for the signer, or showing visible impatience when the signer hesitates, those are red flags. In La Verne, the son sat quietly across the table and let his father speak for himself. That matters.
Is this the right moment?
Dementia symptoms fluctuate throughout the day. Many individuals are clearest in the morning and more confused in the late afternoon — a phenomenon sometimes called sundowning. Scheduling a signing during a window when the signer is typically most alert is something I always discuss with families before I drive out. For this appointment, the son had timed it to mid-morning, when his father was consistently clearest.
What Is a Durable Power of Attorney and Why Does It Matter for Dementia?
The document we notarized that day was a durable power of attorney. The word “durable” is critical when dementia is involved.
A standard power of attorney becomes invalid the moment the principal loses capacity. That means if you sign a regular power of attorney and your dementia later progresses to the point where you can no longer make decisions, the document loses legal effect — at the exact moment you need it most.
A durable power of attorney, by contrast, remains in effect even after the principal loses capacity. Under California Probate Code section 4124, a durable power of attorney must contain specific language stating that it survives the incapacity of the principal. Without that language, the document reverts to a standard — and effectively useless — power of attorney the moment capacity is gone.
For families dealing with a dementia diagnosis, a durable power of attorney is not optional. It is the document that keeps the family out of probate court and allows the agent to manage financial affairs, pay bills, access accounts, and handle legal matters without judicial oversight.

What Happens If You Wait Too Long
This is the conversation no family wants to have, but every family dealing with a dementia diagnosis needs to hear.
When Capacity Is Gone, the Notary Cannot Help
Once a person loses legal capacity, no notary can complete the notarization — regardless of how urgent the situation is or how clearly the family understands what their loved one would have wanted. Without a valid power of attorney already in place, the only remaining path is a court-ordered conservatorship.
What a Conservatorship Actually Costs
Under California Probate Code section 1800, a conservatorship grants a court-appointed person authority over another individual’s personal care, finances, or both. Establishing one requires an attorney, a court investigator, a formal hearing, and ongoing annual reporting to the court. Fees typically range from five thousand to fifteen thousand dollars or more to establish, with recurring costs every year thereafter.
The Cost of Acting Early vs. Waiting
A durable power of attorney, signed while the principal still has capacity, costs a fraction of a conservatorship and accomplishes the same goal without court involvement. The family in La Verne made the right call at the right time. The father still had capacity. The signing was valid. The son now holds the legal authority to help his father manage his affairs without involving a judge.

Frequently Asked Questions
Can a person with dementia sign a power of attorney in California?
Yes, if they have legal capacity at the time of signing. A dementia diagnosis does not automatically disqualify someone. The notary assesses whether the signer understands the document, understands who their agent is, and is acting voluntarily. Early and moderate dementia patients often retain capacity during lucid periods.
What is the difference between a regular and a durable power of attorney?
A regular power of attorney becomes void if the principal loses capacity. A durable power of attorney remains in effect through incapacity. For anyone with a dementia diagnosis, only a durable power of attorney is appropriate.
What if my parent can no longer sign because their dementia is too advanced?
Once capacity is gone, a notary cannot complete the signing. The family’s remaining option is a court-ordered conservatorship, which is significantly more expensive and time-consuming. This is why acting early matters so much.
What should I bring to a power of attorney signing?
A valid, government-issued photo ID is required. Our guide on acceptable identification for notarization covers every option California law accepts, including what to do if the ID has expired. Also review how to prepare for a notarization appointment before we arrive.
How much does a mobile notary cost for a power of attorney signing?
California caps the notary fee at fifteen dollars per notarized signature. Travel fees depend on your location and time of day. Call (626) 248-0349 for a flat, upfront quote with no hidden fees.
Can a notary come to a memory care facility or assisted living community?
Yes. Wet Ink Notary regularly handles signings at memory care facilities, assisted living communities, skilled nursing facilities, and private homes throughout the Inland Empire. Notify the facility ahead of time that a notary will be visiting and ask whether the ombudsman needs to be involved.
Do I need an attorney to draft the power of attorney before you notarize it?
No attorney is required, though consulting one is always a good idea for complex estates. California recognizes the statutory durable power of attorney form, and many families use legal document services to prepare their documents before calling a notary. Regardless of who drafts the document, Wet Ink Notary handles the notarization.
