What is Presumptive Evidence?

Legal Definition
evidence that is considered to be fact until proven otherwise, circumstantial evidence or indirect evidence.
Legal Definition
This term has several meanings in law. (i) Any evidence which is not direct and positive; the proof of minor or other facts incidental to or usually connected with the fact sought to be proved, which, when taken together, inferentially establish or prove the fact in question to a reasonable degree of certainty; evidence drawn by human experience from the connection of cause and effect and observation of human conduct; the proof of facts from which, with more or less certainty, according to the experience of mankind of their more or less universal connection, the existence of other facts can be deduced. In this sense the term is nearly equivalent to "circumstantial" evidence. See 1 Starkie, Bv. 558; 2 Saund. PI. & Ev. 673; Civ. Code Ga. 1895, ยง 5143; Davis v. Curry, 2 Bibb (Ky.) 239; Horbach v. Miller, 4 Neb. 44; State v. Miller, 9 Houst. (Del.) 564, 32 Atl. 137. (2) Evidence which must be received and treated as true and sufficient until rebutted by other testimony; as, where a statute provides that certain facts shall be presumptive evidence of guilt, of title, etc. State v. Mitchell, 119 N. C. 784, 25 S. Bl 783 ; State v. Intoxicating Liquors, 80 Me. 57, 12 Atl. 794. (3) Evidence which admits of explanation or contradiction by other evidence, as distinguished from conclusive evidence. Burrill, Circ. Ev. 89.
