Updated September 4, 2026. Quick answer: Missouri’s Condominium Act has no ratification vote specific to special assessments; only the general annual-budget process, which owners can reject by majority vote, provides any check on the board.
Key statute: Mo. Rev. Stat. § 448.3-103 (executive board / budget ratification, no special-assessment-specific ratification provision); § 448.3-115 (assessments for common expenses, interest rate); § 448.3-116 (assessment liens)
How Missouri lets an association approve it
Approval in Missouri is board-driven, with only a general annual-budget ratification process acting as a check, since Missouri’s Uniform Condominium Act contains no separate ratification requirement specific to special assessments. Under Mo. Rev. Stat. § 448.3-103.1, “Except as provided in the declaration, the bylaws, subsection 2 of this section, or other provisions of sections 448.1-101 to 448.4-120, the executive board may act in all instances on behalf of the association.” The annual budget process, under subsection 3, provides: “Within thirty days after adoption of any proposed budget for the condominium, the executive board shall provide a summary of the budget to all the unit owners…Unless at that meeting a majority of all the unit owners, or any larger vote specified in the declaration, reject the budget, the budget is ratified, whether or not a quorum is present. In the event the proposed budget is rejected, the periodic budget last ratified by the unit owners shall be continued until such time as the unit owners ratify a subsequent budget proposed by the executive board.” No Missouri statute separately addresses ratification of a mid-year special assessment the way Maine’s law does.
The notice you’re owed
Only the general annual-budget notice rule applies, since there’s no special-assessment-specific notice requirement in Missouri’s statute. The board must mail a budget summary within thirty days of adopting the budget and hold a ratification meeting, per section 448.3-103.3 quoted above. The exact window for scheduling that meeting could not be confirmed against the primary text this session, so treat any specific day-range for the meeting date as unconfirmed.
Paying it: plan, interest, and late fees
Missouri’s statute doesn’t address a payment-plan right for special assessments; that’s a declaration or bylaws matter. It does cap interest on late payments: under section 448.3-115.2, “Any past due common expense assessment or installment thereof shall bear interest at the rate established by the association not exceeding eighteen percent per year.”
Unpaid assessments become a lien on the unit under section 448.3-116, foreclosable “in like manner as a mortgage on real estate or a power of sale pursuant to chapter 443,” and “extinguished unless proceedings to enforce the lien are instituted within three years after the full amount of the assessments becomes due.”
Does Missouri require a reserve study?
No. Missouri has no statutory reserve-study or structural-inspection mandate. Section 448.3-114 addresses only the treatment of surplus or prepaid reserve funds and does not impose a funding formula, an engineering study, or an inspection requirement.
Honest gaps
The exact day-range for scheduling Missouri’s ratification meeting could not be pinned down to an exact number from the primary text this session, so treat that specific detail as unconfirmed, even though the notice-and-ratification process itself is confirmed by direct quotation. No special-assessment-specific statutory provision, separate from the general annual-budget-ratification rule, was found in Missouri’s Act.
