Frequently asked questions
Duration is one factor among many in N.M. Stat. Ann. § 40-4-7; courts still analyze comparative resources, children's burdens, health, property awards, and earning capacity—long marriages do not mandate any fixed monthly amount by statute alone.
Parties may seek modification when a substantial and material change in circumstances occurs after entry of the order—such as enduring income loss, health changes, or retirement—supported by current financial affidavits and explanatory exhibits rather than summaries alone.
New Mexico child support uses guideline worksheets, while spousal support analyzes discretionary factors under § 40-4-7; gross income portrayals must stay consistent across both analyses or credibility suffers.
Because statute lists property awarded and debt assigned among factors, unequal equitable distribution—including retirement lumps—directly influences need determinations under N.M. Stat. Ann. § 40-4-7 and duration expectations.
Earning capacity—including evidence of concealed pay, understated business income, or voluntary underemployment—may support imputation when tied to vocational data, job vacancies, licensing barriers, childcare logistics, or health realities reflected in credible records referencing § 40-4-7 fairness goals.
Courts may award pendente lite support consistent with procedural practice; interim awards should logically align factually with arguments that will support—or challenge—ultimate findings under § 40-4-7 after equitable distribution resolves retirement and debts.
Federal law generally dictates treatment; post-TCJA orders are often nondeductible to payors and nontaxable to recipients. Negotiate lumps and monthly obligations with tax advisers when Sandia QDROs or tribal enterprise pay structures complicate net cash assumptions under § 40-4-7.
