What the burden of proof means
Launch library · evergreen read

The burden of proof determines which party in a legal dispute is responsible for proving their claim, and to what standard, with criminal cases typically requiring guilt to be proven beyond reasonable doubt, a considerably higher bar than most civil disputes, a detail that often gets overlooked.
In civil matters, the standard is usually described as the balance of probabilities, meaning a claim needs only to be shown as more likely true than not, reflecting the generally lower stakes compared with a criminal conviction, regardless of the specific circumstances involved, at least in most well functioning systems.
These differing standards exist because the consequences of an incorrect finding vary significantly between contexts, and setting the burden of proof appropriately is one of the ways legal systems try to balance fairness against the risk of error, even if that is not always obvious, which matters more than it might first appear.
