A more thorough explanation:

Term: Quae Plura
Definition: Quae Plura is a legal term that means "what more". It refers to a writ that was used in the past to order the escheator (a person who dealt with the property of a deceased person) to investigate if there were any additional lands or tenements that the deceased person owned at the time of their death, which had not been located yet.
Example: If a person died and their property was being distributed among their heirs, but it was suspected that there were more properties that the person owned, the court could issue a Quae Plura writ to the escheator to investigate and find out if there were any additional properties that had not been accounted for.
This example illustrates how the Quae Plura writ was used to ensure that all the properties of a deceased person were accounted for and distributed among their heirs.
