Concerning gifts, (or more fully, de donis conditionalibus, concerning conditional gifts.) The name of a celebrated English statute, passed in the thirteenth year of Edw. I., and constituting the first chapter of the statute of Westm. 2, by virtue of which estates in fee simple conditional (formerly known as “dona conditionalia”) were converted into estates in fee-tail, and which, by rendering such estates inalienable, introduced perpetuities, and so strengthened the power of the nobles.
