Once filed, a United States judgment remains a lien for how many years, with a possibility to refile for additional years?

A United States judgment, once filed, establishes a lien against the debtor's property for a period of 20 years. This lien can be renewed or refiled for an additional 20 years, thereby extending the enforcement of the judgment for a total of up to 40 years. This provision allows creditors to maintain their claims effectively over a prolonged period, ensuring they have the opportunity to collect the debt if necessary.

Understanding the context of lien durations is essential in the realm of title insurance and property rights, as it directly affects the assessment of property titles and the risks involved in real estate transactions. In this scenario, the correct answer highlights the longevity of a judgment lien in the United States legal framework, reflecting the balance between creditor rights and the time limitations on claims.
