Relocation and Child Custody in New Mexico: The 30-Day Notice Rule

Planning to move with your child after a divorce in New Mexico? You cannot just pack up and go. Even if you have primary custody, the law requires specific notice procedures. Skip them and you risk losing custody entirely.

The Statutory 30-Day Notice

Under NMSA 1978 Section 40-4-9.1(J)(4)(a), any parent planning to change their home city or state of residence must provide the other parent with at least 30 days' written notice stating the date and destination of the proposed move.

In practice, most court-approved parenting plans and local rules expand this to a more detailed process.

The 60-Day Notice in Practice

Standard New Mexico parenting plans typically require the relocating parent to provide a comprehensive Notice of Proposed Relocation at least 60 days before the move, sent by both regular and certified mail with return receipt requested.

The notice must include:

• The new physical and mailing address
• New telephone number
• Names and ages of everyone who will live in the new residence
• The name of the new school and school district
• Specific reasons for the move
• A detailed proposal for a revised timesharing and holiday schedule

The notice must also include a consent/objection affidavit for the non-relocating parent and a warning that failure to file a court objection within 30 days of receiving the notice bars them from opposing the relocation.

How the Other Parent Objects

The non-relocating parent has 30 days after receiving the notice to file a written objection with the District Court and serve a copy on the relocating parent. If they miss that window, they legally cannot oppose the move.

Once an objection is filed, the court schedules an expedited hearing. In joint physical custody cases, the relocating parent bears the burden of proving the move is in the child's best interests.

The court may also refer the case to the Court Clinic for an evaluation or appoint a Guardian Ad Litem to investigate.

What the Court Considers

Judges evaluating relocation disputes weigh factors including:

• The reason for the move — a better job opportunity carries more weight than moving to be closer to a new partner
• The impact on the child's relationship with the non-relocating parent
• Whether a revised timesharing schedule can maintain meaningful contact
• The child's ties to their current school, friends, and community
• The child's preference (especially if they are 14 or older)
• Each parent's history of compliance with existing court orders

What the Court Can and Cannot Do

The court cannot prevent an adult from moving. You have a constitutional right to relocate. But the court can modify the custody order to keep the child in New Mexico with the non-relocating parent if it finds the move is not in the child's best interests.

If the move is approved, the court typically orders a revised timesharing schedule that gives the non-relocating parent extended summer time, alternating holidays, and mandatory virtual visitation.

Travel Cost Allocation

The revised plan must address who pays for the child's travel. Long-distance transportation costs can be factored into the child support calculation as extraordinary expenses. Common arrangements include splitting costs proportionally based on income or having the relocating parent cover all travel expenses since they chose to move.

Moving Without Notice

Moving without providing proper notice — or in violation of the Temporary Domestic Order that automatically issues when a custody case is filed — carries severe consequences. The court can hold the relocating parent in contempt, modify custody to the other parent, and award attorney fees. It also damages your credibility in any future custody proceedings.

The New Mexico Child Custody & Parenting Plan Guide includes a relocation notice template and guidance on proposing a revised long-distance timesharing schedule that courts accept.
