Legal Definitions - jusjurandum

Jusjurandum refers to an oath, which is a solemn promise or declaration, often made in the presence of a higher authority or before a court, affirming the truth of a statement or the intention to perform a duty faithfully.

Here are some examples illustrating the concept of jusjurandum:

• Example 1: Witness Testimony in Court

  Before testifying in a criminal trial, a witness places their hand on a Bible or raises their right hand and solemnly swears to "tell the truth, the whole truth, and nothing but the truth." This formal declaration, made under penalty of perjury, is a jusjurandum. It signifies their commitment to provide honest and accurate information to the court, understanding the legal consequences of falsehood.

• Example 2: Presidential Inauguration

  When a newly elected president takes office, they recite an oath prescribed by the Constitution, promising to "faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States." This public and binding declaration is a jusjurandum, marking their formal acceptance of the responsibilities of the office and their commitment to uphold the nation's foundational laws.

• Example 3: Sworn Affidavit for a Legal Claim

  A person filing a small claims court case might be required to submit a written affidavit detailing the facts of their dispute. They sign this document in front of a notary public, swearing under penalty of perjury that the statements contained within are true and accurate to the best of their knowledge. This notarized, sworn statement constitutes a jusjurandum, providing a legally binding assurance of the veracity of the information presented.
