Sasine (Scots law) is the delivery of feudal property, typically land. Feudal property means immovable property, and includes everything that naturally goes with the property. For land, that would include such things as buildings, trees, and underground minerals. A superior (e.g., a heritor) might authorise his agent or factor to give possession of his property to someone else through a document known as a "precept of sasine". Alternate spellings: seizin, seisin, sasin, seasin, sasing, seasing, sesin, seasin, sesine, seasine, saisine.
