Who Can Witness a Will?

Apr 6

Writing a will is one of the most important things you can do for your family. But in California, signing it isn't enough — you also need the right witnesses. Get this part wrong, and your will could be thrown out in court.

Here's everything you need to know, explained simply.

First: Why Do Witnesses Matter?

Witnesses aren't just a formality. Witnesses serve two very important functions for a valid will: they show that the person making the will had the mental capacity to create it, and they show there was no fraud, duress, or undue influence involved.

In other words, they protect your wishes after you're gone.

How Many Witnesses Do You Need?

California law is very clear about the need to have two other competent adults serve as witnesses when someone signs a will.

Both witnesses must be present at the same time when you sign. Each witness must be present at the same time and must understand that the instrument they are signing is the testator's will.

Who Can Be a Witness?

Under California Probate Code section 6112(a), any natural person generally competent to be a witness may act as a witness to a will. It is recommended that you designate an adult to witness your will to avoid any claims of incompetence down the road.

So practically speaking: your witnesses should be adults who are mentally competent and understand what they're signing.

Who Should NOT Be a Witness?

This is the part most people get wrong. To be a disinterested witness, they must not have a financial interest in the will — meaning the witness cannot be a beneficiary of the will.

What happens if a beneficiary witnesses the will anyway? When an interested witness signs a will, there is a presumption that the gift to that witness was made under duress, menace, fraud, or undue influence. Because of this presumption, the gift to the interested witness is cancelled — though the rest of the will remains valid.

The safest move: choose people who have nothing to gain from the estate. Think neighbors, coworkers, or friends who aren't named in the will.

Can a Notary Replace a Witness?

This is a very common question — and the answer is no. In California, a will cannot be made valid by notarization alone. Simply having a notary public stamp your will does not satisfy the state's requirements for witnessing.

That said, if you are creating a living trust, powers of attorney, or other estate planning documents alongside your will, you may need a notary to validate those documents.

That's where we come in. Book an appointment with Nopa Notary for your power of attorney, living trust, or other estate documents that do require notarization.

What About a Handwritten Will?

California does recognize handwritten wills, also called holographic wills. A holographic will is entirely handwritten and signed by the testator. It does not require witnesses, but must be entirely in the testator's handwriting.

The downside? Holographic wills can be contested if their authenticity, the testator's capacity, or intent is questioned. They're riskier and easier to challenge in court.

Quick Summary

Here's the short version of what you need:

Two witnesses — required for a typed, printed will
Both present at the same time — when you sign
Adults who are mentally competent — recommended
Not beneficiaries of the will — this is critical
A notary is not a substitute for witnesses — but is needed for other estate documents
