In law, an allegation (also called adduction) is a claim of a fact by a party in a pleading, charge, or defense. Until they can be proved, allegations remain merely assertions. There are also marital allegations: marriage bonds and allegations exist for couples who applied to marry by licence. They do not exist for couples who married by banns. The marriage allegation was the document in which the couple alleged (or frequently just the groom alleged on behalf of both of them) that there were no impediments to the marriage.
