10. MARYLAND-SPECIFIC NOTES

• Income Shares Model: Maryland uses the Income Shares Model under Fam. Law § 12-202, considering both parents' adjusted actual incomes.
• Multifamily Adjustment (2025): Effective October 1, 2025, HB 275 introduced a multifamily adjustment reducing a parent's adjusted actual income by 75% of the basic obligation for additional children in the household for more than 92 overnights per year. Documentation is required.
• Shared Physical Custody: Under § 12-201(o), each parent must keep the child overnight for more than 25% of the year and both must contribute to the child's expenses in addition to child support. Current Worksheet B directs users to stop if either parent's percentage is below 25%; § 12-204(m) supplies the calculation, including the 92-to-109-overnight adjustment bands.
• Above-Guidelines Income: The current § 12-204(e) schedule extends through combined adjusted actual income of $30,000 per month. Above that level, § 12-204(d) permits the court to use its discretion in setting support.
• Voluntary Impoverishment: Courts may impute income if a parent is voluntarily impoverished (§ 12-201(b)(2)).
• Modification: Either party may seek modification upon a material change in circumstances.
