I've had a few conversations lately with agents attaching appraisal reports to MLS listings — not maliciously, just not knowing better. It made me dig back into the actual legal basis for why this isn't allowed, and then into the more useful question: how do we let agents legally use the factual data they actually need, without exposing ourselves? Sharing both here. PART 1: The Legal Basis Copyright vests automatically, in you, the moment you create the report. Under 17 U.S.C. § 201, the author owns the copyright unless there's a signed written work-for-hire agreement saying otherwise — made BEFORE the work was done. If you never signed one (and almost none of us have), the report is yours. Full stop. This isn't theoretical. Tim Vining, an appraiser in Washington state, sued a real estate brokerage for using parts of his report in their sales material without permission — and won. First case to establish appraisal reports as copyrightable work product. His report wasn't even registered with the Copyright Office, and he still won — registration isn't required to prove infringement. What delivering a report actually grants a client: a limited license for a specific purpose, not ownership. Fannie Mae's own 1004/70 form proves the model — the client is permitted to disclose the report to the borrower. One named party, one named purpose, in writing. That's the template for everything below. PART 2: How to Actually License Data Out (So Agents CAN Use It Legally) Here's the thing — agents genuinely need some of this data, and right now the only path they have is either bugging you informally or lifting it without permission. You can close that gap yourself, and get paid for it, by formalizing a narrow license instead of leaving the door either fully open or fully closed. Build a simple Third-Party Data Use License — a short, separate document (not the report itself) that does four things: 1. Names who it's for. Specific agent, specific brokerage, specific property/listing. Not a blanket release — it expires with that listing.
