The rest of what we have written about Missouri. Every figure is quoted from Missouri’s own statute or its courts’ own published schedule, and carries the date we last checked it.
Dividing property and money in a Missouri divorce
The money picture for a divorce in Missouri: how property gets divided, what Missouri calls spousal support and how it is decided, whether one spouse can be made to pay the other’s legal fees while the case is running, and — the part nobody publishes — whether Missouri’s own income tax follows the federal rule on alimony.

Every claim is traced to Missouri’s own statute, court rule or revenue department, quoted where the wording carries the meaning. Where we could not verify something, the page says so instead of filling the space. Information, not legal advice — and tax questions in particular need a professional in your state.

Does Missouri follow the federal alimony rule?
Since 2019, federal law has treated alimony as not deductible by the payer and not taxable to the recipient, for any instrument executed after 31 December 2018. Most people assume every state followed. Most did. Not all.
Missouri’s income tax law defines its references to federal law with an explicitly ROLLING conformity clause: any reference to the Internal Revenue Code or federal tax laws ‘shall mean’ those laws ‘as the same may be or become effective, at any time or from time to time, for the taxable year.’ Because Missouri automatically incorporates current federal law, it follows the TCJA’s post-2018 alimony treatment (non-deductible to payer, non-taxable to recipient) without need for any legislative update.
So the federal answer is your answer: post-2018 instruments, no deduction and no inclusion, on either return.

Conformity: rolling
Nationally: 36 states follow the federal rule, 9 have no income tax, 4 are decoupled, and 1 — Maine — we could not establish. The full fifty-state table and what each decoupled state does differently.
How property is divided
Missouri is an equitable distribution state. That means the court divides marital property fairly, which is not a synonym for equally. What counts as marital rather than separate property is frequently the whole argument.
the court shall set apart to each spouse such spouse’s nonmarital property and shall divide the marital property and marital debts in such proportions as the court deems just after considering all relevant factors

Maintenance
Missouri calls it maintenance. Using the state’s own word matters when you are searching for forms or reading a statute.
There is no guideline calculation. A judge weighs the statutory factors and reaches a number.
This is the norm and it is why alimony is the least predictable figure in a divorce. Two judges can reach different answers on the same facts and both be right. It also means the strength of your evidence about income, earning capacity and the standard of living during the marriage does real work.
The maintenance order shall be in such amounts and for such periods of time as the court deems just, and after considering all relevant factors

Child support
Missouri uses the income shares model — both parents’ incomes go into the calculation, and the result is apportioned between you.
Whichever model applies, this is the most predictable number in your case — there is a formula and a presumption that its output is correct. Deviating from it takes written findings. Run it early; it is free, and it anchors everything else.
Guideline: Mo. Rev. Stat. § 452.340.8; Missouri Supreme Court Rule 88.01 and Form 14
How Missouri calculates child support, in detail
Who pays for the lawyers
the court…may order a party to pay a reasonable amount for the cost to the other party of maintaining or defending any proceeding…and for attorney’s fees, including sums for legal services rendered and costs incurred prior to the commencement of the proceeding and after entry of a final judgment
Source: Mo. Rev. Stat. § 452.355.1
the court from time to time after considering all relevant factors…may order a party to pay a reasonable amount for the cost to the other party of maintaining or defending any proceeding pursuant to sections 452.300 to 452.415 and for attorney’s fees
A fee award that only arrives at final judgment is close to worthless to someone who could not afford a lawyer during the case. By then it is over. An interim award is what stops a wealthier spouse winning by attrition.
If you are the lower earner, this is the single most actionable thing on this page. Ask at the first meeting, in these words: “Can we move for an interim award of attorney fees now?” Do not let “we will deal with fees at the end” pass unexamined.
Separately, if custody is contested you may be ordered to pay for a guardian ad litem or a custody evaluator, and the court decides how to split that. What that costs in Missouri, and who bears it.
The thing worth knowing about Missouri
Missouri’s IRC conformity clause (§ 143.091) is a clean example of true rolling conformity — it defines federal-law references to update automatically ‘at any time or from time to time,’ so Missouri’s tax treatment of alimony (and everything else tied to federal income) shifts automatically whenever Congress changes the underlying rule, without any separate state legislative action.
