Which of the following defines a lien?

A lien is a legal right or interest that a lender has in the borrower's property, granted until the debt obligation is satisfied. This means that the creditor has the right to retain possession of the property until the debt is resolved. The essence of a lien is to provide security for the lender, ensuring that they have a claim to the property if the borrower fails to fulfill the financial obligations.

In the context of property law, a lien can arise from various situations, such as mortgages, unpaid taxes, or the non-payment of services rendered. Once the obligation is settled, the lien is removed, and the property owner can regain full control without restrictions.

The other options do not accurately capture the definition of a lien. For instance, maintenance costs pertain to the care of a property and do not create a legal claim over it. A document confirming property ownership refers to deeds or certificates of title, which are different from liens. Lastly, methods to transfer property rights involve conveyancing or selling procedures, which are unrelated to the security interest established by a lien. Thus, understanding that a lien specifically involves a creditor's right against a property until a debt is paid is crucial in recognizing its function in real estate and financing.
