The CIV-161 Order to Show Cause Why Lien form is used when there is a dispute over a lien or encumbrance on the property of a public officer or employee. This situation typically arises when a public officer believes that a lien placed on their property is either unjustified or improperly executed. The need for this form is triggered after a lien has been recorded against their property. - **Petition:** Before using the CIV-161 form, the public officer needs to file a petition outlining the reasons why the lien or encumbrance is invalid. - **Notice of Lien:** Typically, the process is triggered by receiving a notice that a lien has been placed on property. - **Opposition:** There may be an initial dispute or conflict that has led to the placement of the lien, which means legal action is necessary to contest it. Once the petition is filed, this form acts as a court order that requires attendance at a hearing. At this hearing, the respondent must justify the lien's validity, or otherwise, the court may order the lien to be removed. It initiates the formal legal process to challenge the lien, before removal of any unjustified encumbrance.
