Unconditional Lien Waivers and Subcontractors

[Ben Smith]

Has anyone ever had an issue with paying your general contractor and having an Unconditional Lien Waiver signed only to have a subcontractor file a lien on the property?

I'm curious. Luckily, I'm not actually in this situation currently but I am getting all of my paperwork together and I'm wondering what the best way to protect myself against a lien would be (other than the "satisfy all your promises and you shouldn't find yourself in that position"). I would think it would be hectic to pay all subs separately while still maintaining some semblance of an organized payment schedule that doesn't include me having to write and keep track of 100 payments per project.

Thanks in advance,

Ben
