- rei interventus
in Scots law, a doctrine of personal bar that prevents a person who does not want to adhere to a formally defective agreement being allowed to do so by the party who wants the bargain to succeed. There must be important actings by the party wanting to rely on the agreement, known to and permitted by the other party. It prevents locus poenitentiae, which is said to exist between informal agreement and formal execution. Its practical importance has been eclipsed by the regime provided by the Requirements of Writing (Scotland) Act 1995, which provides an equivalent protection for parties affected by a lack of required writing. See self-proving.
