Final answer:
The lien described is a property tax lien, an involuntary lien on real property due to unpaid property taxes.
Step-by-step explanation:
The type of lien being described is a property tax lien, which is a specific, involuntary lien placed on the real property of owners who have failed to pay their property taxes. Local governments or other taxing authorities impose property taxes, which are public charges levied against the inhabitants' property, such as houses, gardens, mills, fields, vineyards, etc.
The tax is based on the fair market value of the property, with each owner providing a sworn declaration of their real estate for assessment. When taxes remain unpaid, the taxing authority can place a lien against the property, which may ultimately lead to a tax foreclosure if the debt is not settled.
