When a loan on real estate is secured by a deed of trust, and is fully or partially paid off, this form is filed with the Public Trustee to request a release of the Deed of Trust. This form does not require the lender to produce the promissory note that was executed with the deed of trust. Only certain types of lenders (see § 38-39-102(1)(a) and (3.5), C.R.S.) may use this process.
