Section 15-19-53 - Assessments, when payable(a) All assessments so made shall be due and payable within thirty days after receipt of notice of assessment, provided that any assessment may, at the election of the owner of the land assessed, be paid in installments with interest, as hereinafter provided. Failure to pay the whole of any assessment within the period of thirty days shall be conclusively considered an election on the part of all persons interested in the assessments, whether under disability or otherwise, to pay in installments.(b) All persons so electing to pay in installments shall be conclusively considered and held to have consented to the improvement and the election shall be conclusively held and considered as a waiver of any and all right to question all power or jurisdiction of the authority to make the improvement, the regularity or the sufficiency of the proceedings, or the validity or correctness of the assessment. However, the waiver shall not apply to any person who has properly filed an action in court, challenging the power or jurisdiction of the authority to make the improvement, within thirty days after receipt of notice fixing the assessments.[Eff 9/17/84] (Auth: HRS §§ 206E-4, 206E-6) (Imp: HRS §§ 206E-4, 206E-6)
