Colorado Revised Statutes Title 31. Government Municipal § 31-35-607. Payment in installments optional

Failure to pay the whole assessment within said thirty days shall be conclusively considered and held to be an election on the part of the persons interested, whether under disability or not, to pay in such installments. All persons so electing to pay in installments shall be conclusively held and considered as consenting to said improvements, and such election shall be conclusively held and considered as a waiver of any right to question the power or jurisdiction of the municipality to construct the improvement, the quality of the work, the regularity or sufficiency of the proceedings, or the validity or the correctness of the assessments or the validity of the lien thereof.
