To break or remove an entail (a legal arrangement that restricts who can inherit property); to free property from entailment.
From dis- (reverse, undo) + entail (from Old French entailler, meaning to cut into). In law, an entail restricted inheritance to a specific line of descendants, and 'disentail' was the legal process of breaking that restriction.
In early American history, Thomas Jefferson worked to abolish entails in Virginia because they kept property locked in aristocratic families—'disentail' was the legal term for breaking these chains and allowing property to be freely bought and sold.
