Partners or joint contractors; sub-letting of contract; statement by sub-contractor; failure to provide; penalty. Whenever, after a contract has been made, the contractor shall associate one or more persons as partners or joint contractors, in carrying out the same, or any part thereof, the lien for labor, services, material, fixtures, apparatus or machinery, forms or form work furnished by a sub-contractor to such contractor and his partners or associates, as originally agreed upon, shall continue the same as if the sub-contract had been made with all of said partners. When the contractor shall sub-let his contract or a specific portion thereof to a sub-contractor, the party furnishing labor, services, material, fixtures, apparatus or machinery, forms or form work for such sub-contractor shall have a lien therefor; and may enforce his lien in the same manner as is herein provided for the enforcement of liens by sub-contractors. Any sub-contractor shall, as often as requested in writing by the owner, or contractor, or the agent of either, make out and give to such owner, contractor or agent, a statement of the persons furnishing labor, services, material, fixtures, apparatus or machinery, forms or form work, giving their names and how much, if anything, is due or to become due to each of them, and which statement shall be made under oath if required. If any sub-contractor shall fail to furnish such statement within 5 days after such demand, he shall forfeit to such owner or contractor the sum of $50 for every offense, which may be recovered in a civil action and shall have no right of action against either owner or contractor until he shall furnish such statement, and the lien of such sub-contractor shall be subject to the liens of all other creditors.
