Divorce is one of the most disruptive life events an estate plan can face. The documents you signed when you were married, your will, your powers of attorney, your advance directive, your beneficiary designations, were built around a life that no longer exists. Some of those documents still name your former spouse. Some give them legal authority over your finances and your medical care. Some will transfer your retirement account to them when you die, regardless of what your will says.
New Mexico law revokes certain provisions automatically when a divorce is finalized. But automatic revocation is not the same as a complete solution. There are gaps, there are documents the law doesn't touch, and there are accounts that bypass New Mexico's revocation rules entirely. Waiting to address your estate plan after divorce is a risk most people don't realize they're taking.
This article walks through what changes automatically in New Mexico, what you need to change yourself, and why doing it promptly matters.
What New Mexico Law Changes Automatically After Divorce
New Mexico follows the Uniform Probate Code, which includes a revocation-on-divorce provision under NMSA 1978, Chapter 45. When your divorce is finalized, certain estate planning provisions that name your former spouse are automatically revoked by operation of law. You do not need to rewrite your will for these revocations to take effect.
Specifically, divorce in New Mexico automatically revokes:
-
Any bequest or devise in your will that leaves property to your former spouse
-
Your former spouse's appointment as personal representative in your will
-
Your former spouse's appointment as trustee, if named in a trust that includes revocation-on-divorce language
-
Your former spouse's authority as your healthcare agent under a healthcare power of attorney, in most circumstances
For purposes of the revoked provisions, your former spouse is treated as though they predeceased you. That means the gift or appointment passes to whoever your will names as the alternate, if you named one. If you didn't, the estate or appointment falls into the residue of your estate or is handled under New Mexico's default rules.
This automatic revocation provides some protection. But it has real limits.
What New Mexico Law Does NOT Change Automatically
The revocation-on-divorce rules under New Mexico's Uniform Probate Code do not apply to everything. Several categories of assets and documents are outside the statute's reach, and these are the ones most likely to cause serious problems if left unaddressed.
Beneficiary Designations on Retirement Accounts and Life Insurance
This is the most important gap, and the one that catches New Mexico families off guard most often.
Retirement accounts governed by federal law, including 401(k) plans, 403(b) plans, and most pension plans, are subject to a federal law called ERISA. Under ERISA, beneficiary designations on these accounts are not automatically revoked by divorce under state law. The account goes to whoever is named on the beneficiary designation form, period, regardless of what your will says and regardless of the divorce.
The U.S. Supreme Court addressed this directly in a case involving a Washington state resident whose ex-wife received his entire 401(k) because he never updated the beneficiary designation after divorce, even though he had executed a new will. The Court held that the federal designation controlled. New Mexico residents face exactly the same risk.
Life insurance policies present the same problem. If your former spouse is named as the beneficiary on a life insurance policy, they will receive the proceeds when you die unless you update the designation. The divorce does not change it.
IRAs operate differently from employer-sponsored plans under ERISA, but the practical result in New Mexico is often the same: state revocation-on-divorce rules may not apply, and the named beneficiary controls.
Joint Accounts and Payable-on-Death Accounts
Bank accounts held jointly with right of survivorship, and accounts with payable-on-death designations naming your former spouse, may not be affected by New Mexico's revocation-on-divorce statute. These accounts pass by operation of law to the named survivor or beneficiary, outside of your will.
After divorce, review every joint account, every POD designation, and every TOD (transfer-on-death) designation on financial accounts and investment portfolios. Update each one individually.
Financial Power of Attorney
New Mexico's revocation-on-divorce rules for wills do not automatically extend to a financial power of attorney. If your former spouse is named as your agent under a durable financial power of attorney, that document may still be valid after your divorce, depending on its terms.
Even if the document includes language that revokes the agent's authority upon divorce, you should not rely on that language alone. Execute a new financial power of attorney naming the agent you actually want, and formally revoke the prior document in writing with notice to your former spouse and any financial institutions holding copies.
Trusts
Revocable living trusts require careful attention after divorce. New Mexico's revocation-on-divorce statute applies to some trust provisions, but the interaction between the statute and the specific language of your trust can be complex. A trust that names your former spouse as a beneficiary, trustee, or successor trustee may or may not be fully affected by automatic revocation depending on how the document was drafted.
After divorce, have your trust reviewed by your estate planning attorney. Do not assume automatic revocation covers everything in a trust document.
What You Should Do Immediately After Divorce Is Finalized
The right time to update your estate plan is as soon as your divorce decree is entered. Don't wait until things feel settled. The divorce itself is the trigger.
Update your will. Even though New Mexico law revokes provisions benefiting your former spouse, your will still reflects the planning decisions you made when you were married. Your personal representative may now be someone you no longer trust in that role. Your alternate beneficiaries may not reflect your current wishes. Your residuary estate may flow in a direction you didn't intend. A full rewrite, not just a codicil, is usually the right approach after divorce.
Update all beneficiary designations. Contact every plan administrator, insurance company, and financial institution where you have a beneficiary designation on file. Request a change of beneficiary form for each account and submit it promptly. Keep a copy of every completed form. Follow up to confirm the change was processed.
Execute a new financial power of attorney. Name the agent you want now, not the person you trusted during your marriage. Formally revoke the prior document and notify your former spouse and any institutions that had the old document on file.
Execute a new healthcare power of attorney and advance directive. Even where New Mexico's revocation-on-divorce rules may protect you, do not leave your medical decision-making authority in an ambiguous state. Execute a clean new document naming your chosen healthcare agent, and make sure your doctors and any hospitals in your area have the updated version on file.
Review and update your trust. If you have a revocable living trust, have your attorney review it in light of the divorce. Consider whether the trustee, successor trustee, and beneficiary designations still reflect your intentions. If your former spouse holds any role in the trust, address it explicitly rather than relying on automatic revocation.
Review joint account ownership. Retitle or close any joint accounts that still include your former spouse. Update POD and TOD designations on all financial accounts and investment accounts.
Review your HIPAA authorization. If you have a HIPAA authorization on file with your healthcare providers that names your former spouse, revoke it and file an updated authorization naming whoever you actually want to have access to your health information.
Community Property Considerations After New Mexico Divorce
New Mexico is a community property state, which means assets acquired during the marriage are generally owned equally by both spouses. A properly finalized divorce decree should address the division of community property. But the decree itself does not automatically retitle accounts, deeds, or other assets. You need to follow through on the transfers the decree orders.
If real estate was awarded to you in the divorce, confirm that a deed transferring your former spouse's interest has been recorded with the county clerk. If retirement account assets are being divided pursuant to a Qualified Domestic Relations Order, confirm the QDRO has been submitted to the plan administrator and processed correctly.
These steps are separate from updating your estate plan, but they intersect with it. An estate plan built on assumptions about what you own is only as reliable as the underlying ownership records.
Updating Your Plan If the Divorce Is Not Yet Final
If your divorce is pending but not yet finalized, your estate plan is in a particularly vulnerable position. You are still legally married, which means your spouse may have rights under your current documents and under New Mexico community property law.
During a pending divorce, consider the following:
-
Review whether your current power of attorney gives your spouse authority you would not want them to exercise during the divorce proceedings
-
Consult with your attorney about whether you can revoke or amend your power of attorney while the divorce is pending
-
Consider updating your advance directive to name a different healthcare agent
-
Do not retitle assets or change beneficiary designations without consulting your divorce attorney first, as some changes may be restricted by temporary orders entered in the divorce case

Frequently Asked Questions
Does divorce automatically revoke my will in New Mexico?
Divorce does not revoke your entire will in New Mexico. It revokes specific provisions that benefit your former spouse and their appointments as personal representative or trustee, treating them as though they predeceased you. The rest of your will remains in effect. This is why a full review and rewrite after divorce is strongly recommended rather than relying on automatic revocation to clean everything up.
What happens to my 401(k) if I forget to update the beneficiary after divorce?
Under federal ERISA law, your 401(k) will go to whoever is named on the beneficiary designation form, even if that person is your former spouse and even if you have a new will that says otherwise. New Mexico's revocation-on-divorce rules do not override federal law on employer-sponsored retirement accounts. Updating beneficiary designations immediately after divorce is one of the most important steps you can take.
Can my former spouse still act as my healthcare agent after divorce in New Mexico?
In most circumstances, New Mexico's revocation-on-divorce rules will revoke your former spouse's authority as your healthcare agent. However, do not rely on this protection alone. Execute a new healthcare power of attorney naming your chosen agent as soon as your divorce is finalized, and make sure your healthcare providers have the updated document.
How long do I have to update my estate plan after divorce?
There is no legal deadline, but the risk is present from the moment your divorce is finalized. If you die or become incapacitated before updating your documents, gaps in the automatic revocation rules, particularly around beneficiary designations, could result in assets going to your former spouse. Update your plan as promptly as possible after the divorce decree is entered.
