When can an Affidavit be used?

Affidavits serve as written statements made under oath, and they can be utilized in a variety of legal proceedings to assert facts. They provide a way for an individual to present information that can be used as evidence in court. By using an affidavit, the person swears that the information contained within it is true to the best of their knowledge, which can help establish credibility.

In the context of the question, the use of an affidavit in legal proceedings to assert facts is appropriate because it allows parties to provide evidence, support claims, or clarify issues without needing to appear in person. This can be particularly useful in cases where testimony is needed but a physical presence in court is not feasible.

Other options, while potentially related to the use of affidavits, do not encapsulate the broader application of affidavits in legal proceedings. For instance, affidavits are not limited to foreclosure cases, nor are they inherently used to transfer ownership of property or declare a lien. Those actions often require other legal documents and processes. Thus, option D correctly captures the primary function of affidavits in asserting factual statements in a wide range of legal contexts.
