Dividing property and money in a New Mexico divorce
The money picture for a divorce in New Mexico: how property gets divided, what New Mexico 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 New Mexico’s own income tax follows the federal rule on alimony.

Every claim is traced to New Mexico’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 New Mexico 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.
New Mexico personal income tax starts from federal adjusted gross income, and the state defines ‘Internal Revenue Code’ as ‘the United States Internal Revenue Code of 1986, as amended’ (rolling conformity, not a fixed pre-TCJA date). New Mexico has no separate statutory addition or subtraction modification requiring alimony to be added back to or subtracted from federal AGI, so the post-TCJA federal rule (non-deductible to payer, non-taxable to recipient, for instruments executed/modified after Dec. 31, 2018) flows through to the New Mexico return unchanged.
So the federal answer is your answer: post-2018 instruments, no deduction and no inclusion, on either return.

Conformity: rolling (statute defines the IRC as ‘the United States Internal Revenue Code of 1986, as amended’)
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
New Mexico is a community property state. Property acquired during the marriage is generally owned by both of you, and the starting point is a division of that community estate rather than an open-ended fairness inquiry.
community property” means property acquired by either or both spouses during marriage which is not separate property. … [I]t is the duty of the trial court to divide equally the community property of the spouses.
Source: N.M. Stat. Ann. § 40-3-8 (definition/characterization); § 40-4-7(A) (division on dissolution); equal-division rule established by case law (e.g. Michelson v. Michelson, 1974-NMSC-022; Otto v. Otto, 1969-NMSC-074)
Spousal support
New Mexico calls it spousal support. 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.
When making determinations concerning spousal support … the court shall consider: (1) the age and health of and the means of support for the respective spouses; (2) the current and future earnings and the earning capacity of the respective spouses…

Child support
New Mexico 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: N.M. Stat. Ann. § 40-4-11.1 (basic child support schedule; Worksheets A and B)
How New Mexico calculates child support, in detail
Who pays for the lawyers
the court may … provide for the support of either party during the pendency of the proceeding, as in its discretion may seem just and proper. The court may make an order, relative to the expenses of the proceeding, as will ensure either party an efficient preparation and presentation of his case.

In any proceeding for the dissolution of marriage … the court may … provide for the support of either party during the pendency of the proceeding … The court may make an order, relative to the expenses of the proceeding, as will ensure either party an efficient preparation and presentation of his case.
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 New Mexico, and who bears it.
The thing worth knowing about New Mexico
New Mexico is a community property state that also retains an income-shares child support model and a spousal-support statute (§40-4-7(B)(1)) that explicitly authorizes courts to award distinct statutory categories of support — rehabilitative, transitional, indefinite, or lump-sum — rather than a single undifferentiated ‘alimony’ award.
