How to Make a Parenting Plan in New Mexico
Staring at a blank Form 4A-302 and trying to figure out how to turn it into a workable parenting plan is one of the most stressful parts of a New Mexico divorce. The court requires very specific sections, and missing any of them means your plan gets kicked back.
What Form 4A-302 Actually Requires
New Mexico's official Custody Plan and Order form is the backbone of every parenting plan in the state. Under NMSA 1978 Section 40-4-9.1, your plan must address these mandatory components:
Decision-making authority. You need to specify whether custody is joint or sole across five areas: residence, medical and dental treatment, education, religion, and recreation. For joint custody, the plan must state that neither parent can make major changes without consulting the other first.
Periods of responsibility. This is the actual timesharing schedule — which parent has the child on which days. The court expects a detailed, specific calendar, not vague language like "reasonable visitation."
Holiday and vacation schedules. The plan must spell out exactly how major holidays, school breaks, and summer vacations are divided. Most plans use an alternating-year structure with specific exchange times.
Transportation and exchange arrangements. Who drives the child to exchanges? Where do exchanges happen? The plan needs clear answers, especially if parents live far apart.
Dispute resolution process. The plan must include a specific method for resolving future disagreements — mediation, parenting coordinator, or court hearing — before either parent can take unilateral action.
Building the Timesharing Schedule
The schedule you propose needs to match your child's age and developmental stage. The Second Judicial District Court Clinic publishes guidelines that judges across New Mexico reference when evaluating plans.
For school-age children (5-12), the most common arrangements are:
- 2-2-3 rotation: Parent A has Monday-Tuesday, Parent B has Wednesday-Thursday, and weekends alternate. This gives consistent midweek structure.
- 5-2-2-5 rotation: Parent A always has Monday-Tuesday, Parent B always has Wednesday-Thursday, and weekends alternate. Reduces confusion about which parent has which midweek days.
- Alternating weeks (7/7): The child spends one full week with each parent. Works well for older children who can handle longer separations.
For high-conflict situations, judges often prefer the 7/7 or 5-2-2-5 schedules because they minimize the number of exchanges between parents.
The 35% Overnight Threshold
One detail that catches many parents off guard: your timesharing schedule directly affects child support calculations. If each parent has the child for at least 35% of the year (128 overnights), the court uses Worksheet B, which accounts for duplicated household costs by multiplying the basic support by 1.5.
If one parent falls below 128 overnights, the court uses Worksheet A, which typically results in a higher support payment from the non-primary parent. A difference of just a few overnights near that threshold can shift the calculation significantly.

Common Mistakes That Get Plans Rejected
Vague language. "Every other weekend" is not specific enough. The court wants "Friday at 5:00 PM to Sunday at 6:00 PM on alternating weekends, beginning [date]."
Missing the dispute resolution clause. Without a written process for resolving disagreements, the court will send your plan back. Include specific steps: direct discussion first, then mediation, then court intervention.
Ignoring the child's age. A plan proposing alternating weeks for a two-year-old will get scrutinized heavily. Infants and toddlers need more frequent transitions with shorter separations from their primary attachment figure.
Forgetting right of first refusal. Many judges expect the plan to include a provision that if one parent cannot care for the child during their time (due to work travel, for example), the other parent gets first option before a babysitter is called.
Getting It Right the First Time
A well-drafted parenting plan saves you thousands in legal fees and multiple trips back to court.
