De Donis

Concerning gifts, (or more fuily, 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.
