The standard is met if the proposition is more likely to be true than not true. The standard is satisfied if there is greater than fifty percent chance that the proposition is true. Lord Denning, in "Miller v. Minister of Pensions", described it simply as "more probable than not." Until 1970, this was also the standard used in juvenile court in the United States. This is a far lower burden than "beyond a reasonable doubt," the threshold a prosecutor must meet in criminal trials.
