A more thorough explanation:

ne unques executor

Ne unques executor is a legal term that means "never executor." It is a plea used in court to deny that the defendant or plaintiff is an executor as claimed.

For example, if someone is accused of being an executor of a will, they may use the plea of ne unques executor to deny that they are the executor. This plea can be used by either the defendant or the plaintiff in a case.

Another example is if a person is named as an executor in a will, but they never accepted the role or acted as an executor. They can use the plea of ne unques executor to deny that they are the executor.

These examples illustrate how the plea of ne unques executor can be used to deny that someone is an executor as claimed in a legal case.
