1. What Is an Uncontested or Simple Divorce in New Mexico?

In New Mexico, divorce is often described as a dissolution of marriage. The court system does not create a separate case type called “simple divorce.” Instead, people use “simple” to describe an uncontested case where:

  • Both spouses agree the marriage should end, and
  • You have a full agreement on the issues that apply (property, debts, and if applicable: parenting and child support), and
  • You file the correct forms and complete the required steps so the judge can sign the final decree.

New Mexico is known as a no-fault divorce state. In most uncontested cases, spouses use no-fault language (for example, that the marriage relationship has broken down and there is no reasonable chance of reconciliation) rather than trying to prove wrongdoing.

2. Who Qualifies for an Uncontested Divorce in New Mexico?

Before you spend time on paperwork, make sure you’re allowed to file in New Mexico and that your situation is a good fit for an agreement-based (uncontested) case.

Residency requirements

In general, at least one spouse must have lived in New Mexico long enough for the court to have jurisdiction (commonly described as a six-month residency requirement). If your case involves recent moves, out-of-state issues, or uncertainty about jurisdiction, consider legal advice before filing.

When your case is a good fit for an uncontested divorce

  • Both of you accept the marriage is over.
  • You can exchange financial information honestly and completely.
  • You agree on how to divide property and debts.
  • If you have children, you agree on custody/time sharing and child support.
  • The non-filing spouse will cooperate with signatures and deadlines.

When uncontested divorce may not work well

  • Domestic violence, threats, stalking, or safety concerns.
  • Hidden assets, unclear income, or one spouse controls all finances.
  • Complex property (a business, multiple homes, significant retirement issues).
  • High-conflict disputes about children or relocation.
  • Pressure to sign quickly without understanding the consequences.

If any of these apply, a pure DIY approach can be risky. Consider speaking with a New Mexico family law attorney or legal aid clinic before signing final documents.

3. Step-by-Step Overview of the Uncontested Divorce Process (Key 4A Forms)

Many New Mexico self-help filers use the statewide 4A-Series domestic relations forms. The exact packet depends on whether you have children and how service is handled, but the typical flow is:

  • Prepare agreements → complete forms → file → complete service or waiver → wait the statutory minimum → submit final decree for judge signature.

Step 1 – Start with the mandatory cover sheet (a common “clerk rejection” issue)

New Mexico courts commonly require the Domestic Relations Information Sheet (Form 4A-101) to open a family law case. If this cover sheet is missing, many clerks will not accept the filing.

Step 2 – File the correct Petition form

For many cases, the petition form is:

  • Form 4A-102 (Petition for Divorce – no children), or
  • Form 4A-103 (Petition for Divorce – with children).

Step 3 – Put your agreement in writing (property, debts, and support)

Uncontested cases work best when the agreement is written clearly and consistently. Many couples use the Marital Settlement Agreement (Form 4A-301) to document property division, debt responsibility, and spousal support (if any).

Step 4 – If you have children, complete the child-related forms

If minor children are involved, the court expects custody/time sharing and child support details to be complete and consistent. A common core form is the Parenting Plan / custody plan and order (Form 4A-302).

Step 5 – Service or waiver (how cooperative couples avoid sheriff costs)

After filing, the other spouse must be brought into the case through proper service unless they cooperate by signing the appropriate entry of appearance / waiver / consent paperwork. In many districts, these “cooperative service” options are addressed in the Stage Three domestic relations materials (often referenced with Form 4A-300 Stage Three instructions). Always follow your local district court’s self-help packet and clerk instructions.

Step 6 – The 30-day waiting period (minimum timeline)

New Mexico is known for a 30-day statutory waiting period. In general, the court will not sign the final divorce decree until at least 30 days have passed after the key service/acceptance step is completed. This is a minimum; paperwork issues and court workload can add time.

Step 7 – Submit the correct Final Decree form (this is a “hard stop”)

One of the easiest ways to get rejected at the end is using the wrong decree form:

  • Without children: Final Decree of Dissolution of Marriage (Form 4A-305)
  • With children: Final Decree of Dissolution of Marriage (Form 4A-306)

Why it matters: the “with children” decree includes child-related orders that must line up with your parenting plan and support terms. If you submit the “without children” decree in a case with children, the court may reject it or require corrections.

4. Special Issues When You Have Children

When children are involved, the court must ensure the outcome protects the best interests of the child. Even if both parents agree, the judge may scrutinize whether the paperwork is complete and workable.

  • Parenting schedule: weekdays, weekends, holidays, school breaks, transportation, and exchanges.
  • Decision making: how major decisions will be handled (education, medical, etc.).
  • Child support: support terms that align with New Mexico guidelines and accurate income information.

Most importantly, make sure your final paperwork matches: a case with children should typically end with the Final Decree (Form 4A-306), not the “without children” decree.

5. How Long Does an Uncontested Divorce Take in New Mexico?

There’s no guaranteed timeframe, but uncontested cases are usually much faster than contested ones. A practical way to think about it is:

  • Minimum: the 30-day waiting period after the key service/acceptance step.
  • Common reality: many uncontested cases take 1–3 months depending on how quickly paperwork is completed and how long judge review takes.
  • Common delays: missing the cover sheet (4A-101), incomplete service/waiver paperwork, unclear settlement terms, or using the wrong final decree (4A-305 vs. 4A-306).

6. What Does an Uncontested Divorce Cost?

Costs can vary by district and situation, but most DIY filers should plan for:

  • Court filing fee: commonly around $137 to open a domestic relations (divorce) case (confirm the current amount with your local District Court clerk).
  • Service costs: if you must use a sheriff or process server (often avoided in cooperative cases when the other spouse signs the correct waiver/acceptance paperwork).
  • Notary, copies, and certified copies: small administrative costs that add up.

If cost is a major concern, one of the biggest savings in a cooperative divorce is properly using the district’s service waiver/acceptance option so you do not pay for formal service.

7. When a DIY Divorce Might Not Be Right for You

A DIY, uncontested divorce is designed for cooperative, straightforward situations. It may not be the right approach if you’re facing serious risks or long-term consequences you don’t fully understand.

  • Domestic violence or safety concerns – safety comes first; legal support may be essential.
  • Heavy power imbalance – if one spouse controls money/documents, a “paperwork only” process can produce unfair outcomes.
  • Complex assets – businesses, major retirement accounts, or separate property claims can raise legal and tax issues.
  • High-conflict parenting disputes – contested parenting issues often require legal advice.
  • Pressure to sign quickly – if you feel rushed, get independent guidance before signing a settlement.

PlainDivorce.com can help you understand process and paperwork, but it cannot tell you what is “fair” in your specific case. If you’re unsure, talk with a New Mexico family law attorney or legal aid clinic before signing final documents.

8. Where a Self-Help Divorce Kit Fits Into the Process

Many people feel overwhelmed by divorce paperwork even when the case is uncontested. A structured self-help kit is most useful when it helps you avoid the predictable “hard stops,” such as:

  • Including the mandatory cover sheet: Domestic Relations Information Sheet (4A-101)
  • Choosing the right petition: 4A-102 (no children) vs. 4A-103 (with children)
  • Keeping agreements consistent: Marital Settlement Agreement (4A-301) and (if applicable) Parenting Plan (4A-302)
  • Submitting the correct final decree: 4A-305 (no children) vs. 4A-306 (with children)
  • Tracking the service or waiver step so the 30-day waiting period can run

9. Frequently Asked Questions

What is an uncontested or simple divorce in New Mexico?

An uncontested (or “simple”) divorce in New Mexico is a dissolution of marriage where both spouses agree the marriage should end and they also agree on the key terms (parenting and child support if applicable, and property/debt division) so the court can approve the case without a major dispute.

What is the mandatory cover sheet to start a New Mexico divorce case?

Many New Mexico courts require the Domestic Relations Information Sheet (Form 4A-101) to open a divorce case. If it’s missing, clerks often reject the initial filing.

Which final decree form should we use: 4A-305 or 4A-306?

Use 4A-305 for a divorce without children. Use 4A-306 for a divorce with children. Using the wrong decree is a common reason final paperwork gets rejected or delayed.

How long is the waiting period for divorce in New Mexico?

New Mexico is known for a 30-day statutory waiting period. In general, the judge cannot sign the final divorce decree until at least 30 days have passed after the key service/acceptance step is completed. Court workload and paperwork issues can still add time beyond that minimum.

10. Final Thoughts and Next Steps

Starting a divorce is emotionally difficult, even when both spouses agree to keep things civil. The good news is that New Mexico offers a clear path for uncontested divorce when spouses can cooperate and follow the standardized 4A-Series forms closely.

Before you file, take a moment to:

  • Confirm you can file in New Mexico (jurisdiction/residency) and in the correct District Court.

  • Use the correct “starter” forms, especially 4A-101 and the correct petition (4A-102 or 4A-103).
