Do not assume a three-day rule applies
For example, the U.S. FTC Cooling-Off Rule covers certain sales made away from a seller's permanent business location, but it has important exclusions.
Contract rights and legal rights differ
An agreement may offer cancellation even where no statute requires it, while local law may create rights that are not obvious from the contract.
Act promptly
When a cancellation right exists, method and timing can matter.
Use the correct jurisdiction
Check current government or consumer-protection guidance for the place and type of transaction involved.
This page provides general educational information. For a real agreement, dispute, court filing, estate matter, debt problem or authorization document, check the current rules that apply where you live and obtain qualified advice when the consequences are significant.
