Glossary · Doing the deal
In short
A blocking right is the power of a minority owner to prevent certain actions, even if they own less than 20% of the business. The SBA considers someone with a blocking right a key principal for personal guarantee purposes.
If your operating agreement gives a non-owner or minority owner the ability to veto critical business decisions, that person may be subject to a personal guarantee under the control principle. Review your business's governing documents carefully to identify any such rights.
