What is a supporting affidavit?

A supporting affidavit is indeed an affidavit that accompanies a motion to provide a factual basis for the claims or assertions being made. This type of affidavit is crucial in legal proceedings as it serves to provide sworn statements from witnesses or parties that substantiate the information presented in the motion. It helps to lend credibility and support to the legal arguments being made by laying out essential facts, thereby assisting the court in making informed decisions.

Affidavits are typically used to present evidence or to establish certain facts that may not need to be proven at trial, making them pivotal in pre-trial motions or for summary judgment motions. A supporting affidavit usually includes specific details, personal knowledge, and facts that are relevant to the motion, supporting the party's legal argument.

The other options describe different legal concepts or documents but do not accurately reflect the purpose and function of a supporting affidavit. For example, an affidavit that provides testimony in court focuses more on the actual testimony rather than the preliminary support for a motion. Similarly, an agreement between parties in dispute and a legal document that ends a legal dispute refer to settlement agreements or judgments and do not relate to the function of a supporting affidavit in providing factual support.
