How do I know that my contractor file an extension on a original lien.
Are we dealing with a single family dwelling? If so, that extension must be obtained by court order in a special proceeding. If it is any other type of private project, then (assuming that it's the first extension) be done by filing a simple notice of extension, which must be served on you. If you haven't received such a document, you can check the county clerk's office; the lien and its extension are a matter of public record.
