A more thorough explanation:

An involuntary lien is a legal claim against a property or asset that is imposed without the owner's consent. This type of lien is typically created by law or court order, and the owner of the property or asset has no choice but to comply with the lien. Involuntary liens can be placed on property for a variety of reasons, such as unpaid taxes, judgments, or mechanic's liens.

For example, if a homeowner fails to pay their property taxes, the government may place an involuntary lien on the property to secure payment of the taxes owed. Another example is if a contractor performs work on a property but is not paid, they may file a mechanic's lien against the property to ensure they receive payment for their services.

These examples illustrate how an involuntary lien can be imposed on a property or asset without the owner's consent, and how the lien can be used to secure payment of debts or obligations.
