A more thorough explanation:

Definition: De placito is a Latin term used in law to describe a plea or action being brought. It means "of a plea" and is often used in declarations to specify the type of case being presented.

• De placito debit - "Of a plea of debt"
• De placito land - "Of a plea of land"
• De placito novae disseisinae - "Of a plea of new disseisin"

These examples illustrate how de placito is used to specify the type of case being presented. For instance, "de placito debit" would indicate that the case is related to a debt, while "de placito land" would indicate that the case is related to land ownership.
