Is the Lender required to file and record a Disburser's Notice prior to our first draw being funded to our GC?

There is no standared form disburser notice. You speak with construction counsel and they draft it. Once you have the form, you can revise as necessary for each project. The information required in that notice is in C.R.S. § 38-22-126(2). However, there is no penalty for failing to do this notice. It can create potential risks down the road if a notice to disburser is received. 

You really should have experienced counsel to help with this as construction lending is extremely complicated and requires solid agreement and advice. If this business has multiple members or shareholders, your attorney will also advise you about a proper written shareholders' or opearting agreement. Reach out and get a consultatation. Most of us offer free consultations.
