In what type of law are presumptions and burdens of proof defined according to applicable jurisdiction?

The definition of presumptions and burdens of proof is primarily governed by state law. Each state has its own rules and statutes that delineate how these concepts operate within its jurisdiction, including the specific types of presumptions that may be applied in different legal contexts, such as civil or criminal cases. This state-specific framework allows for variations in how evidence is handled across the United States.

While federal law does establish certain standards regarding burdens of proof in federal courts, particularly in areas like civil rights or federal criminal law, the more general rules and applications are grounded in state law. Therefore, one should look to the relevant state statutes and rules of evidence for the presumption and burden of proof applicable to specific legal situations.

Federal law can influence certain cases when they arise under federal jurisdiction, but it does not solely define presumptions and burdens across the wider realm of legal practice, which primarily falls under the state's responsibility. Hence, the answer regarding the jurisdiction that defines these legal components accurately focuses on state law.
