A more thorough explanation:

Definition: Praeceptio haereditatis is a legal term used in Scots law to describe when someone takes their inheritance before they are supposed to. This is also called a lucrative succession. Example: If someone's grandfather left them a house in his will, but the person took ownership of the house before their grandfather passed away, that would be an example of praeceptio haereditatis. Explanation: This legal term is used to describe a situation where someone takes their inheritance before they are supposed to. This can cause problems because the person may not be aware of any debts or obligations that their ancestor had, and they could become responsible for them. The example shows how someone taking ownership of a house before their grandfather passed away would be considered praeceptio haereditatis because they are taking their inheritance before they are supposed to.
