Authorized Representative: Who Can Sign and File Your California Proposition 19 Claim

When you claim a Proposition 19 benefit, the paperwork asks for a signature, and it matters who signs. This article explains what an "authorized representative" is, who may legally sign and file a Proposition 19 claim in California, and why a real estate agent usually cannot. It also shows how a power of attorney fits in, one important limit that catches families after a death, and the practical steps to file correctly. Every source linked at the end is a government page.

What an Authorized Representative Is

An authorized representative is a person the property owner allows to act for them on a specific matter, here signing and filing a Proposition 19 claim. The most common example is an attorney or an accountant who holds a valid power of attorney for the owner. The representative acts in the owner's place, yet the owner still carries responsibility for the claim, which the form certifies as true under penalty of perjury.

Who May Sign a Proposition 19 Claim

California limits who may sign these claims, and the right signer depends on how the property is held. The property owner signs their own claim. If a trust holds the property, the trustee signs. If the owner cannot sign, a guardian or conservator may sign for them. And an agent who holds a valid power of attorney may sign as the owner's authorized representative. You file the signed claim with the assessor in the county where the property sits, after the sale and purchase are complete, and you do this yourself rather than through escrow.

Why a Real Estate Agent Usually Cannot File It

A real estate agent helps you buy or sell, and that role does not include signing your tax claim. An agent can gather the documents the assessor needs, such as the closing statements that show each home's price, and can point you to the right form. An agent cannot sign or file the Proposition 19 claim for you, though, unless that same person also holds a valid power of attorney from you. So treat the filing as your responsibility, and use your agent for help with documents rather than for the filing itself.

How a Power of Attorney Works in California

A power of attorney is a written document in which you, the principal, give another person, your agent, authority to act for you. California calls the agent the attorney-in-fact. California's Power of Attorney Law, found in the Probate Code, sets the rules, including that the document be in writing and signed, then either notarized or witnessed. For a property tax claim, the power of attorney needs to cover your property tax or financial matters, so the agent's authority reaches the filing. California's tax agencies also provide a property tax power of attorney form, known as BOE-392, that you can use to name a representative for these matters.

One Limit That Catches Families: A Power of Attorney Ends at Death

A power of attorney works only while the person who granted it is alive, and it ends the moment that person dies. This matters for an inherited home, because a child cannot use a deceased parent's power of attorney to file the parent-child Proposition 19 claim. Instead, the new owner signs. That signer is usually the heir who inherited the home, the trustee of the trust that holds it, or the executor of the estate. Knowing this in advance keeps the claim from being signed by the wrong person, which the assessor can reject.

What This Means When You File

A few habits keep the signature question from costing you the benefit. Sign the claim yourself whenever you can, because you are the person the form asks for. If someone signs for you, confirm that they hold a valid power of attorney, and attach a copy of it to the claim. File with the correct county assessor, meaning the county where the property is located, and keep a copy of everything you send. If you are filing for an inherited home, first confirm who now owns it, since that new owner, the trustee, or the executor is the proper signer.
