Contractors

Release myself from responsibility and/or lien put on my house for any unpaid money for work down to my house. Do I need to hire a lawyer to write this up or can I purchase a form and have it signed by my tenant and any known contractors. My tenants have hired and paid a tile contractor and hardwood floor contractor to put in floors. My tenants have singed a contract stating they will rent our house until June 2010 with intent to purchase at that time.

On the prevailing wage act if an investigation is underway by the dept. of labor, on seven separate construction contracts that are completed, and all wage documentation has been lost, what are the repercussions we will be facing?

I have a roofing contractor that provided services, but has yet to provide an actual contract , estimate, and warranty. I've paid enough to cover his actual costs for materials and possibly enough for labor. He has steadfastly refused to provide the info I require and has made reference to possibly placing a lien for more than 10 times amount of the actual materials on my home. Is this legal?

I would like to know what the legal limitations are for a small business license for example, is there a bid limitations and what is my scope of work on a house? Can I do anything no matter what the size or amount of money I charge? This will help me decide what I need from you.

A contractor has filed a lien against my wife and I because our roofer did not pay for supplies. We have been told they will foreclose on our house to get payment. We have paid the roofers in full. We are in Colorado where the lien trust fund statute exists. How should we proceed? Pay the supplier and sue the roofer for the money we paid out + attorney fees? Is it worth it for $3000?
