To fill out the RCSD-S form, match the property, date, and party names at the top to the underlying purchase or listing agreement, check the one box that describes your authority (trust, entity, power of attorney, or estate), complete only that section with the exact legal names and dates from your authority documents, and sign at the bottom with your representative title. The form is a disclosure that gets attached to the main contract so the buyer, escrow, and title company can see who is actually signing for the seller and under what authority.
When You Need This Form
The Representative Capacity Signature Disclosure – Seller is a California Association of Realtors form used whenever the person signing for the seller is not simply an individual selling their own property. It covers four situations, and you use it by checking the one that applies to you:1Plata Realty Group. Representative Capacity Signature Disclosure (For Seller Representatives)
- The property is held in a trust and you are signing as trustee.
- The property is owned by a corporation, LLC, partnership, or other entity, and you are an authorized officer, member, or partner.
- You are acting under a power of attorney signed by the actual owner.
- The property belongs to a probate estate, conservatorship, or guardianship, and a court has appointed you as executor, administrator, conservator, or guardian.
If you own the property outright as an individual and are signing for yourself, you do not need the RCSD-S. The form exists to close the gap between the signer and a seller that is a legal arrangement rather than a natural person acting alone.
Filling In the Top of the Form
The header identifies the underlying agreement the disclosure is attached to. Enter the type of agreement (purchase agreement, listing agreement, or other), the date of that agreement, the property address, and the buyer and seller names. Copy these details verbatim from the primary contract. A seller name on the RCSD-S that does not match the seller name on the listing agreement is one of the fastest ways to generate a title objection at closing, so treat this as transcription work, not paraphrasing.
Section A: Trust
Check Section A if title is held in a trust. Write out the full legal name of the trust exactly as it appears on the recorded deed, including the date the trust was created. A name like “The Miller Family Trust dated June 12, 2015” has to be transcribed character for character. Dropping “The,” abbreviating the date, or shortening the trust name will trigger a title objection later.
Indicate whether you are the sole trustee, a co-trustee, or a successor trustee. When there are co-trustees, all of them generally need to sign unless the trust document specifically allows one to act alone. The certification of trust that you provide to the title company will state which powers require all trustees and which do not.2California Legislative Information. California Code Probate Code 18100.5 – Certification of Trust
Section B: Entity
Check Section B when the seller is a corporation, LLC, partnership, or other business entity. Identify the type of entity and use the checkboxes to indicate whether an authorizing resolution from the entity’s governing body is attached. Attach the resolution up front. If you leave it for later, the escrow officer will ask for it during the closing window, and that request often lands at the worst possible moment.
Title companies typically want to see a board resolution or secretary’s certificate for a real estate sale, and for an LLC they want the operating agreement pages that show signing authority. Have those documents in hand before you fill out the form.
Section C: Power of Attorney
Check Section C if you are signing as an attorney-in-fact. Mark whether the power of attorney is general or specific to this property, and enter the date the POA was executed. The RCSD-S itself is not a power of attorney; the POA must already exist, signed by the principal, before you use this form.1Plata Realty Group. Representative Capacity Signature Disclosure (For Seller Representatives)
For a real estate sale, the underlying POA has to contain language specifically authorizing you to convey or sell the property. A vague general grant of authority often will not satisfy a title company. California Civil Code section 1095 requires that when an attorney-in-fact signs an instrument transferring real property, they subscribe the principal’s name and then add their own name as attorney-in-fact.3California Legislative Information. California Code Civil Code 1095 The POA must be notarized, and title companies typically require it to be recorded in the county where the property sits.
Section D: Estate
Check Section D when the seller is a probate estate, conservatorship, or guardianship. Enter the Superior Court case name and case number, indicate your role (executor, administrator, conservator, or guardian), and mark whether you are acting as a sole or co-representative.
Your authority to sell comes from letters testamentary if there is a will, or letters of administration if there is not. Under the California Independent Administration of Estates Act, a personal representative with full authority can sell real property without court confirmation, while a representative with limited authority needs court supervision of the sale. The title company will ask to see your current letters and will confirm they have not been revoked or expired.
Documents to Have Ready
The RCSD-S discloses your authority; it does not prove it. Gather these supporting documents before you sign the form so the escrow officer is not chasing paperwork later:
- Trust: a certification of trust under Probate Code section 18100.5, signed by all currently acting trustees as an acknowledged declaration. It confirms the trust exists, names the current trustee, describes the trustee’s powers, and states whether the trust is revocable, without disclosing distribution terms.2California Legislative Information. California Code Probate Code 18100.5 – Certification of Trust
- Corporation: a board resolution authorizing the sale and a secretary’s certificate confirming who may sign. Some title companies accept the resolution alone.
- LLC: a member or manager resolution authorizing the sale, plus the operating agreement pages showing signing authority.
- Power of attorney: the original or a recorded copy of the POA, notarized, with specific language granting authority to convey real property. If the POA is more than a year old, expect the title company to also require an affidavit that the POA has not been revoked, as provided under Probate Code section 4305.
- Estate: current letters testamentary or letters of administration. If your authority under the Independent Administration of Estates Act is limited rather than full, add proof of court confirmation of the sale.
How to Sign and Deliver the Form
The signature block has fields for your signature, your printed name, and your title. Write the title that matches your capacity: “Trustee,” “Successor Trustee,” “Managing Member,” “President,” “Attorney-in-Fact,” “Executor,” and so on. When there are two representatives, such as co-trustees, both use the two signature lines and each dates the signature independently.
Sign the same way on every document in the transaction. For a trust, that looks like “Jane Miller, Trustee of The Miller Family Trust dated June 12, 2015.” For a power of attorney, Civil Code section 1095 requires the principal’s name first, then your own name as attorney-in-fact.3California Legislative Information. California Code Civil Code 1095 Signing your name alone on one document and with your title on the next will get flagged.
Once signed, attach the RCSD-S to the purchase agreement or listing agreement as an addendum. The form has an acknowledgment-of-receipt line for the buyer or broker to sign and date. Deliver the completed form to the buyer, the escrow holder, and your own agent early in the transaction. The form’s own language states that its disclosure supersedes any representative capacity representation in the underlying agreement, so delivering it promptly locks in the authoritative record of who is signing and why.1Plata Realty Group.

Mistakes That Delay Closing
Name mismatches are the biggest problem. If the trust name on the form reads “Miller Family Trust” but the recorded deed says “The Miller Family Trust dated June 12, 2015,” the title company will flag the discrepancy and may require a corrective deed or affidavit before issuing a policy. Copy the entity or trust name from the recorded deed, not from memory.
Missing supporting documents come next. Submitting the RCSD-S without the trust certification, board resolution, LLC operating agreement pages, POA, or letters testamentary means the escrow officer is collecting proof of authority in the days before closing rather than during due diligence. Gather the authority documents before the form is signed.
Finally, the RCSD-S is sometimes confused with a document that grants authority. It does not. It discloses authority that already exists in a trust instrument, corporate resolution, power of attorney, or court order. If the underlying document does not actually give you power to sell the property, the RCSD-S cannot supply what is missing, and the sale will not close on your signature alone.
