Which of the following is an example of a non-legal description of a property?

A deliverable street address is indeed an example of a non-legal description of a property. While a street address is widely used for navigation and communication, it does not provide the precise geographic boundaries or legal definition of the property itself.

In contrast, legal descriptions such as metes and bounds, lot and block, and the government lot system are established and recognized methods that define property boundaries in a way that is legally enforceable. Metes and bounds involves a detailed description of the property's boundaries using physical landmarks and measurements. The lot and block system refers to subdivisions recorded in a plat map, whereas the government lot system uses a rectangular survey to describe land. These methods provide explicit details that can be used in legal documents, whereas a street address lacks that specificity and legal recognition.
