Can I refuse to give financial details even after a buyer signs an NDA?

Yes. A signed NDA governs how information is protected once you choose to share it — it doesn't create any obligation for you to actually disclose anything. Signing an NDA is a precondition many sellers set before releasing sensitive material, not a trigger that automatically entitles the buyer to see it. You remain free to continue holding back financial details until you're satisfied the buyer is serious, qualified, and worth the exposure.

That said, an NDA that a buyer signed expecting meaningful information in return, followed by continued stonewalling with no real path forward, can understandably frustrate a genuine buyer and stall a deal that might otherwise progress. If your hesitation is about verifying seriousness, it's often more productive to explain what you're waiting for — proof of funds, a written indication of interest — rather than withholding indefinitely without explanation. But legally, the choice of what and when to disclose remains yours throughout the process. A Treadstone business lawyer can help you set out a clear, staged disclosure plan so buyers understand what triggers the next level of information.
