Contractors

If a subcontractor goes bankrupt, can the subcontractor's-subcontractor file a mechanic's lien against the owner for the total amount of services rendered even though the general contractor paid the subcontractor almost the total contract price?

We are a contractor. If we sign a 'waiver of lien' form as requested by our client, do we waive our right to file a lien if they don't pay? The lien waiver states 'For and in consideration of the sum of ___ dollars, upon receipt will be acknowledged, the undersigned hereby waives and releases any and all liens, claims, or rights of liens upon the following described premises...' They say they need it to pay us, but we don't want to give up our rights. How should we proceed?

We installed voice and data cable at a hotel under construction in DeSoto, Texas. We required 50% down and 50% upon completion. They told us to invoice by Jan 20 and we would get paid Feb 15. We have still not been paid and there is lots of unpaid contractors. Should I file a lien? What is the best action to take to get paid?

I am a subcontractor for a kitchen remodeling company. I filed liens against 4 homeowners. If the homeowner has paid the kitchen contractor and the contractor hasn't paid me, will the homeowner still have to pay me to release the lien?

My company has a mechanics lien recorded in Colorado. After recording we realized we had another amount to bill. Do we file a second lien for the amount billed? Do we release the first lien and file a second for the total amount owed?
