What can you do before and during the job?

Know who is on your job and keep every paper that arrives about it, including notices from subcontractors and suppliers. Each step below is general guidance unless it quotes a statute. This is practical reasoning, not legal advice and not a finding from any agency.

  1. Before you sign, ask your contractor in writing which subcontractors and suppliers will work on the job. California's § 7159 warning says: "You can protect yourself from liens by getting a list from your contractor of all the subcontractors and material suppliers that work on your project."

    Source: California Business and Professions Code § 7159 (official text, California Legislative Information), read 22 October 2026 (our saved browser copy, as read on 2026-10-22).

  2. In Texas, the model disclosure in § 53.255 says: "Before construction commences, your contractor is required to provide you with a list of the subcontractors and suppliers the contractor intends to use on your project."

    Source: Texas Property Code chapter 53, sections 53.021, 53.254 and 53.255 (Texas Constitution and Statutes), read 22 October 2026.

  3. Keep one folder, paper or digital, for the contract, every change order, every invoice and every notice from someone you did not hire. Note the day each notice arrived.
  4. When a notice arrives from a subcontractor or supplier, read it the same day and ask your contractor about it in writing before your next payment.
  5. For the end of a Texas job, the model disclosure in § 53.255 says: "Under Texas law, on final completion of the work and before final payment, the contractor is required to furnish you with an affidavit stating that all bills have been paid."

    Source: Texas Property Code chapter 53, sections 53.021, 53.254 and 53.255 (Texas Constitution and Statutes), read 22 October 2026.

  6. If a lien document is recorded against your house, discuss it with an attorney in your state before deciding how to respond.
  7. Do not set notices aside. California's § 7159 warning ends: "REMEMBER, IF YOU DO NOTHING, YOU RISK HAVING A LIEN PLACED ON YOUR HOME."
