Hiring and working with contractor(s)…
When hiring a contractor it is a good idea to get a written estimate, which includes the specific work
to be performed, the time frame involved, and your cost.
When making a payment request a detailed receipt of the work and materials you are paying for.
It is also a good idea to request a waiver of lien in consideration for final and full payment. A final
waiver of lien waives and releases the contractor’s right to claim a lien for labor, services, or
materials, furnished for the project.

There may be certain, specific, special requirements not indicated in this pamphlet.
