Onus Probandi

[Latin, The burden of proof.] In the strict sense, a term used to indicate that if no evidence is set forth by the party who has the Burden of Proof to establish the existence of facts in support of an issue, then the issue must be found against that party.

See: cloud, suspicion

ONUS PROBANDI, evidence. The burden of the proof.
     2. It is a general rule, that the party who alleges the affirmative of any proposition shall prove it. It is also a general rule that the onus probandi lies. upon the party who seeks to support his case by a particular fact of which he is supposed to be cognizant; for example, when to a plea of infancy, the plaintiff replies a promise after the defendant had attained his age, it is sufficient for the plaintiff to prove the promise and it lies on the defendant to show that he was not of age at the time. 1 Term. Rep. 648. But where the negative, involves a criminal omission by the party, and consequently where the law, by virtue of the general principle, presumes his innocence, the affirmative of the fact is also presumed. Vide 11 Johns. R. 513; 19 Johns. R. 345; 9 M. R. 48; 3 N. S. 576.
     3. In general, wherever the law presumes the affirmative, it lies on the party who denies the fact, to prove the negative; as, when the law raises a presumption as to the continuance of life; the legitimacy of children born in wedlock; or the satisfaction of a debt. Vide. generally, 1 Phil. Ev. 156: 1 Stark. Ev. 376; Roscoe's Civ. Ev. 51 Roscoe's Cr. Ev. 55; B. P. 298; 2 Gall. 485; 1 McCord, 573; 12 Vin. Ab. 201; 4 Bouv. Inst. n. 4411.
     4. The party on whom the onus probandi lies is entitled to begin, notwithstanding the technical form of the proceedings. 1 Stark. Ev. 584; 3 Bouv. last. n. 3043.
