The short answer
If the title says a company or a trust owns the car, a person has to sign for the owner, and TxDMV looks at how they sign. The agency's Motor Vehicle Title Manual (August 2026 edition) says that when the owner is a firm, an agent must sign for it in the "Signature of Owner or Agent" space, and a company name in that space must agree with the owner's name on the title. When a trustee signs, whether you need extra paperwork depends on how the owner is named on the title. Mismatched names, signature stamps, and an e-signed title are other places a Houston sale can stall. Sort out who signs, and with what documents, before you ask for offers.
This article is based on Chapter 11 ("Signature - Authority to Sign," §§11.1 to 11.4) of the TxDMV Motor Vehicle Title Manual, which we opened for this post. It's general information, not legal advice. For what your particular entity needs, ask the buyer or your county tax office.
Signing for a company
From §11.2 of the manual:
- If the owner on the title is a firm or company, an agent must sign for it in the "Signature of Owner or Agent" space on the title application.
- A company name shown in the signature space must agree with the owner's name. The manual's example is "XYZ Company by John Doe."
- If the agent's authority has to be shown, as with a power of attorney, the notation "Power of Attorney," "POA," or "P/A" must appear next to their signature, and proof of that authority must be attached.
- In the manual's example of a buyer named "Joe Doaks d.b.a. Doaks Motor Company," no authority is required for an agent to sign for the firm or company.
- "Inc." and "Co." are not interchangeable. TxDMV says not to change one to the other, and not to use a corrected-title application to fix it unless there's an affidavit from the previous owner verifying the correct name. Otherwise the title has to be assigned from one to the other. If the title and the entity's real name don't match, find out before the buyer does.
Section 11.4 adds that a power of attorney can be given to a firm, association, or corporation, and the agent should clearly indicate by their signature that they're signing for it.
Signing as a trustee
Section 11.2 says evidence of authority isn't needed when a person signs as, or for, a "Trustee," unless they're signing as trustee of a trust, an estate, a bankruptcy, or a minor. Table 11-1 shows how it works in practice:
- Owner "John Doe," signed "John Doe, Trustee": no authority required.
- Owner "ABC Company," signed "John Doe, Trustee": no authority required.
- Owner named as a trust (for example, "John Doe Trust Estate"), signed by the trustee: a Statement of Fact or an Affidavit of Trust is required.
- Owner named as a living or family trust (for example, "John and Mary Doe Living or Family Trust"), signed by the trustees: a Statement of Fact or Affidavit of Trust.
The manual explains that a Statement of Fact signed by the trustee is acceptable in place of the trust agreement itself. It must name the person or persons who appointed the trustee and say whether the agreement is on file with the county clerk; if it is, the recording number must be included. If the trustee has someone sign for them under a power of attorney, a notarized original or certified copy of that POA must go with the transaction.
The manual also says no one may sign for the estate of a deceased person without legal authority attached, such as letters testamentary or an affidavit of heirship. That's a separate situation with its own paperwork.
Names, stamps, and e-signatures
Even the right person can sign the wrong way:
- The surname must agree. §11.1 says the owner's name and signature should agree with each other and with the buyer's name on supporting evidence. A shortened first or middle name is fine in the manual's examples, but "the surname must agree in all cases."
- Signature stamps are not acceptable.
- E-signatures are acceptable on non-secure documents. On a secure document, which the manual says includes a secure title and the secure power of attorney form VTR-271-A, an electronic signature is accepted only if the transaction goes through webDEALER, TxDMV's dealer system. It won't be accepted if the paperwork is physically brought to the county tax office. Don't assume an e-signed title will work. Ask the buyer how they'll submit it.
- Signing someone else's name without legal authority on an assignment of title is an offense under Transportation Code §501.155, which the manual quotes as a third-degree felony. If you're acting for the owner, sign as an agent and attach your authority.
Checklist before you sell
- Read the face of the title. Is the owner a person, a company, or a trust? Copy the name exactly.
- Decide who signs, in what capacity: owner, agent for the company, or trustee.
- Gather authority: a POA, a Statement of Fact, or an Affidavit of Trust, depending on the table above.
- Use a wet-ink signature on the title unless the buyer confirms otherwise.
- Fill in the odometer reading and sale date, and match Form 130-U. Our Form 130-U checklist covers it.
- Handle any lien. See lien release timing.
- If you make a mistake on the title, don't use correction fluid. See title mistakes and white-out.

What this post is not promising
- We aren't lawyers, and this isn't legal advice about your company, trust, or authority to sign.
- We don't know how any particular buyer or county tax office will review your documents, and TxDMV or the county office has the final word.
- We don't promise any offer amount or timing.
Bottom line
When a company or trust owns the car, the title can be signed correctly or incorrectly, and the difference is often paperwork, not price. Match the signing capacity to the owner's name on the title, attach whatever authority is required, avoid stamps, and confirm how e-signatures would be handled. Then ask for offers.
