What must be signed by the customer before entering into a contract on a property with an active WDO warranty?

The correct choice is significant because Form 13671 is specifically designed to ensure that the customer is fully aware of any existing Wood-Destroying Organism (WDO) warranty before entering into a contract. This form provides essential information regarding the terms of the warranty, including coverage details and any responsibilities the customer may have under the agreement.

Understanding this form's requirements is crucial for compliance with state regulations, as it protects both the customer and the service provider. The use of this form ensures that the customer has acknowledged the warranty's existence and its implications, thus fostering transparency in the contractual relationship.

The other forms mentioned do not pertain to the acknowledgment of an active WDO warranty, serving different purposes that are not relevant to this particular scenario. By focusing on signing the correct form, it helps clarify responsibilities and rights in the context of property treatment and ongoing pest management.
