What actually triggers an E&O claim against a real estate agent?

CRES, a real estate E&O insurer, puts the pattern plainly: “real estate liability does not end at closing. In many cases, that is when exposure begins.” That matches what agents actually report — the deal closes clean, and the claim shows up weeks or months later, once a buyer runs into something they didn’t expect.

The claim you didn’t see coming

A common version: a buyer closes, then decides six months later they want to add a detached unit. The lot doesn’t allow it. Now they’re arguing the agent should have flagged the restriction during due diligence — even though the agent worked the checklist exactly as trained. Intent and fault barely matter at that stage; once a complaint is filed, the defense bill starts regardless of who’s right. CRES’s own claims data backs this shape: nondisclosure allegations, disputes over repairs or inspection findings, and buyer dissatisfaction after move-in are the three recurring triggers, and “even well-managed deals can lead to complaints.”

The other steady source: paperwork, not judgment

Disclosure and due-diligence disputes get the attention, but small documentation errors are the quieter, more frequent claim driver:

• A missed signature on a required form.
• A contingency deadline that slipped by unnoticed.
• A wrong date on an addendum.

None of these involve bad advice. They’re clerical. But a missed deadline can void a contingency, and a voided contingency can cost a client real money — which is exactly the kind of “error” E&O exists to answer. Documentation habits are also the one part of this an agent fully controls, which is why insurers push saving and organizing transaction communications as a claims-reduction step, not just a filing chore.

Where GL stops and E&O starts

The line is the same one that trips up buyers everywhere: general liability answers physical incidents — someone tripping at an open house, property damage during a showing. It does not answer claims about advice, paperwork, or disclosures; per the Insurance Information Institute, a standard CGL policy “generally does not cover professional errors.” E&O is the policy built for exactly that gap. The general mechanics of that boundary apply here without modification — real estate just supplies some of the clearest examples of each side.

Questions people actually ask

Can an agent get an E&O claim without doing anything wrong? Yes, and it’s the norm rather than the exception. Most claims start from a buyer’s after-the-fact complaint, not a documented mistake — the checklist can be followed perfectly and a claim still gets filed.

Do disclosure disputes usually favor the agent or the buyer? Neither reliably — intent is hard to prove in either direction, which is why these tend to drag out rather than resolve quickly. That’s a defense-cost problem regardless of the eventual outcome.

Are documentation errors a big deal if the deal still closed? They can be. A missed signature or a blown contingency deadline can surface as a claim long after closing, once a client decides it cost them money.

Does E&O cover claims about a property I bought or sold myself? Forms vary on this — see the exclusions covered in do realtors need E&O insurance before assuming your own-account deals are covered the same way.

Claim-pattern data is CRES’s own published experience; treat it as representative, not exhaustive. Read your policy’s actual exclusions rather than assuming any of the above is automatically covered.
