Which of these is an example of a document that might indicate a title defect?

A power of attorney is indeed a type of document that might indicate a title defect. This type of document allows one individual to act on behalf of another in legal matters, which can include signing documents related to the transfer of property. If a power of attorney was executed improperly or if the authority granted is not clear or comprehensive, it might affect the validity of a property transaction. This means that any documents executed under that power could be invalid, leading to potential defects in the title.

In contrast, a purchase contract generally outlines the terms of a sale but does not directly indicate issues with the title itself. A survey report provides information about the property's boundaries and any encroachments but is primarily concerned with physical aspects of the land rather than legal ownership. A title report offers an overview of the current status of the title and any issues present but is typically used to clarify title defects rather than indicate them directly. Thus, while each document serves a unique purpose, a power of attorney can specifically suggest complications related to title validity.
