A more thorough explanation:

jocus partitus

jocus partitus is a term used in history to describe a gambling agreement made by people involved in a lawsuit. This means that the parties involved in the lawsuit would make a bet on the outcome of the case.

For example, if two people were involved in a lawsuit, they might make a jocus partitus agreement where they would bet on who would win the case. If one person won the case, they would get the money that was bet.

Another example would be if two people were involved in a lawsuit over a piece of land. They might make a jocus partitus agreement where they would bet on who would get the land. If one person won the case, they would get the land and the money that was bet.

These examples illustrate how jocus partitus was used in history as a way for people to gamble on the outcome of a lawsuit.
