Which of the following best describes a landlocked property?

A landlocked property is best described as one that cannot be accessed without crossing another person’s land. This condition occurs when a parcel of land is surrounded by other properties, leaving it without any direct access to public roads or thoroughfares. This situation can lead to challenges regarding access rights and can complicate the property owner's ability to utilize the land effectively.

In contrast, the other options do not capture the essence of being landlocked. Access to public roads would imply that the property is not landlocked. Boundary disputes may exist for many reasons unrelated to the accessibility of the property and do not inherently define a landlocked property. Multiple lease agreements pertain to the management or use of the land but do not affect its direct accessibility.
