Hello, I am a subcontractor stated my job with this property owner never pay me the first part of the agreement now my lean is about to expire how can I do an extension if he is not answering me at all .
You need the owner's signed agreement to get an extension. If you can't get an extension, file a foreclosure lawsuit before your lien expires. Include in your lawsuit claims for breach of contract against the contractor that hired you and recovery under the prompt payment statutes, and you may be able to recover your attorney's fees and interest.
