The Cyclopedic Law Dictionary
In conveyancing, the word "over" prior estate. Thus, in what is commonly called the "name and arms clause" in a will or settlement, there is generally a proviso that, if the devisee fails to comply with the condition, the estate is to go to some one else. This is a limitation or gift over.
