Signing, Notarizing, and Witnessing Your Documents

By Jay S. Yu, Esq., Yu & Yu Law, Fullerton, California · Last reviewed October 2026

A California will needs two adult witnesses who watch you sign, and documents such as the deed to your trust and your power of attorney usually need a notary. You can find a notary at many banks, shipping stores, and mobile notary services. Choose witnesses who do not inherit anything under your documents.

The execution (also known as the proper signing of legal documents) process often requires two key roles: two witnesses and a Notary Public. Understanding your options for finding these individuals is helpful, especially if you prefer to sign closer to home or on a tight schedule.

What Is the Difference Between a Notary and a Witness?

Before you start looking, let's clarify why each role is important:

• Witnesses (typically 2 required for a Will): Their primary role is to observe you signing your Will (and often other documents) and then sign themselves. They attest that you appeared to be of sound mind, were signing voluntarily, and that it was you who signed the document. Their testimony could be crucial if the Will is ever challenged.

  • The Golden Rule: Witnesses should be "disinterested." This means they should not be a beneficiary, an heir, or, ideally, a named fiduciary (like an Executor or Trustee) in the document. Using a disinterested witness is essential to prevent future legal challenges.

• Notary Public (required for most documents): A Notary Public is a state-appointed official who acts as an impartial witness to the signing of a document. Their role is to verify your identity (using a government-issued ID), ensure the signing is voluntary, and then affix their official stamp and signature.

Where Can You Find a Notary Public?

Finding a Notary is usually quite straightforward, as they are professionals who serve the general public.

• Your Bank or Credit Union: Many financial institutions provide free or low-cost notary services, often for account holders. Call ahead to confirm availability and if they have any restrictions on notarizing estate planning documents like Wills or Trusts.

• Local Mail & Shipping Stores (e.g., The UPS Store, FedEx Office): These retail locations almost always have a Notary Public on staff, though they will charge a fee per notarized signature.

• Mobile Notaries: For maximum convenience, you can hire a mobile notary who will travel to your home or office. A quick online search for "mobile notary near me" will provide several options. This often costs more but provides flexibility.

• Public Libraries or City/Town Clerk's Offices: Some public facilities offer notary services, often for free or a minimal fee. Always call in advance.

Where Can You Find Witnesses for a Will?

Finding two qualified witnesses can sometimes be trickier, as they need to be independent and available at the same time as you and the Notary.

• Your Neighbors or Friends: These are often the easiest and most available option. Just remember the Golden Rule: they should not be a beneficiary or stand to inherit from your estate.

• Coworkers or Professional Acquaintances: People you know and trust, but who are not involved in your estate plan, are excellent candidates.

• Bank Employees (If allowed by policy): If you are signing at your bank, ask if two employees can serve as witnesses in addition to the Notary. Be aware that some banks prohibit employees from witnessing legal documents due to internal policy.

• Ask Your Notary: If you hire a mobile notary, you can often ask if they have access to witnesses for an additional fee. Some professional signing services provide both roles.

A Few Critical Tips Before Signing Day

1. Bring Proper ID: You, the Notary, and all Witnesses will need a current, government-issued photo ID (like a driver’s license or passport).

2. Do NOT Sign in Advance: All documents must be signed in the presence of the Notary and/or Witnesses. Do not sign or date anything until instructed to do so at the signing meeting.
