Legal Definitions - confirmatio

Definition: Confirmatio is a Latin term that means "confirmation." In legal terms, it refers to the confirmation of a voidable estate.

Examples:

• Confirmatio crescens: This type of confirmation enlarges an estate. For example, if a landlord grants a tenant a lease for a certain period, but then confirms the lease for a longer period, it is a confirmatio crescens.
• Confirmatio diminuens: This type of confirmation decreases the services that a tenant must perform. For instance, if a tenant is required to provide maintenance services for a property, but the landlord confirms that the tenant only needs to provide cleaning services, it is a confirmatio diminuens.
• Confirmatio perficiens: This type of confirmation ratifies a wrongful and defeasible title, or makes a conditional estate absolute. For example, if a person acquires a property through fraud, but then the rightful owner confirms the title, it is a confirmatio perficiens.

These examples illustrate how confirmatio can be used in different legal contexts to confirm or modify the terms of an estate or title.
