When to Update Your NM Estate Plan

There are a few situations and life events listed below that should prompt you to update your estate plan as soon as possible.

A Divorce

Revisiting estate planning after a divorce in New Mexico is critical. A divorce automatically revokes a former spouse’s inheritance rights stemming from language in a will or trust document. It may also automatically revoke beneficiary designations for certain accounts, like retirement accounts,  but you can’t always 100% rely on this being the case. 

Regardless, you should thoroughly review your documents to eliminate (or, if you want, preserve) your ex’s share of your estate once your final divorce decree has been settled.

A Marriage (Or Remarriage)

Incorporating your new spouse into your estate plans is essential. Keep in mind that 50% of community property acquired during the marriage must be left to your spouse through your will or other arrangements. New Mexico community property estate planning is key to avoiding conflicts with the law or other documents, conflicts that could result in parts of your will being set aside, in extreme cases.

You can keep certain property separate through a prenuptial (or postnuptial) agreement, but there are also aspects of your estate you likely want to adjust to support your spouse in the event of your death.

The Death or Estrangement of a Primary Heir 

If someone, such as an adult child, was set to inherit a large portion of your estate, then you should adjust your estate plan accordingly if they pass on or you decide to disinherit them. Updating beneficiaries in New Mexico can prevent a situation where an account or other asset becomes intestate after the expected recipient passes or cannot be contacted.

A Home Purchase, Sale, or Other Major Change to Your Asset Portfolio

Major assets can become a risk factor if they are not incorporated into your estate plan. Make sure to conduct a complete New Mexico estate plan review when you experience a major acquisition, loss, asset purchase, asset sale, or other major change to your portfolio.

Your Retirement

Retiring means accessing funds like your 401(k) or IRA. It can also result in a change in insurance coverage as you transition to Medicare. You may even move or purchase a second home as a result of life changes.

Be sure to review your retirement account beneficiary designations at this stage. You should also form a plan to revise your estate plan once you have a clearer idea of what your situation will look like over the next 5 to 10 years.

Changes to State or Federal Laws

New Mexico doesn’t update its laws impacting estate planning too often. But, when it happens, the effects can be wide-ranging. The IRS or federal codes can similarly implement changes that could have a significant impact on the execution of your estate plan.

These changes may not even result in negative effects. For example, updates made to the federal estate tax exemption amounts in 2025 prevented a reset to much lower exemption amounts.

Planning for Chronic Disease Treatment or End-of-Life Care

If you have received a worrying diagnosis or just want to get ahead of any possible medical problems, it is important to review and update your estate planning documents while you still have the legal capacity to do so.

Having an up-to-date power of attorney and advance health care directive is particularly important because your agent may have the power to affect your estate plan. To mitigate this, you can limit their authority. Or, you can provide them with guidance if you trust their judgment and want them to make decisions that align with your goals, values, and preferences.

Other Desired Changes

You may wish to make updates to your will, a trust, and other documents periodically. Be sure to review your documents at least once every three to five years to ensure they reflect your wishes, your current situation, and current laws.

How to Amend a Will or Trust in New Mexico

Amending a will in New Mexico is possible, but it may be more convenient instead to simply revoke a will and replace it with a new one. This may sound like an extra step, but it can help eliminate confusion, contradictions, or other problems that can arise from trying to maintain an outdated document.

If you are committed to changing your will, this can be accomplished by adding a separate document called a codicil. The codicil requirements in New Mexico are the exact same as properly executing a will (NM Stat § 45-2-502). Namely:

• The codicil must be in writing.
• The codicil must be signed by the testator (or signed at their direction).
• The testator’s signing (or directed signing) must be witnessed by at least two competent adult witnesses, who will then sign the codicil themselves.

Because amending a will in New Mexico requires roughly the same steps as executing a new one, an attorney may recommend that you instead do the latter. Starting a new will afford you the opportunity to thoroughly review it and document your specific wishes, without having to worry about avoiding contradictions with a previous document.

When creating a new will, ensure that your old will is destroyed and that your new will has been created according to the requirements for New Mexico wills. Also, inform your chosen personal representative of the existence of the updated will.

An attorney can assist you with deciding when to update a will in New Mexico. No matter whether you decide to amend a will or create a new one, they can help you draft a document that uses precise and clear language. They’ll also help you go through the process of having the document witnessed to ensure it can be used to settle your estate when the time comes.

Amending or Revoking a Trust

The steps required for amending or revoking a trust depend on the type of trust that was created. 

A revocable trust can be changed or revoked at any time by its creator (who is known as the trust’s grantor. Similar to a will, updating a living trust in New Mexico requires that the new document or codicil be signed by the grantor. They must also have the new document notarized.

Any trustees or successor trustees should be informed of changes to the trust instrument. You may also need to notify the trust’s beneficiaries if the changes affect their distributions.

You can revoke a revocable trust in New Mexico using the following methods (NM Stat § 46A-6-602):

• Following a procedure described in the trust instrument.
• Executing a will or codicil that explicitly revokes the trust or disposes of property that would otherwise be handled by the trust.
• Any other method manifesting clear and convincing evidence of the settlor’s intent.

True to their name, irrevocable trusts are much more difficult to amend or revoke. The method for making changes or revoking the document depends on the type of irrevocable trust and other circumstances. 

In most cases, full consent of all beneficiaries is needed before any changes can occur. You may also need a court order for the changes to take effect.

Because this process can be time-consuming, costly, and lead to unpredictable results, it is highly recommended to enter into irrevocable trust planning with a large degree of caution. Even something as simple as updating beneficiaries in New Mexico can lead to significant challenges. Working with an experienced attorney can help you ensure that you get everything right the first time, eliminating the need to update the irrevocable trust in the future.

Modifying Beneficiary Designations

Your estate plan may include the following types of beneficiaries:

• 401(k), IRA, and other retirement beneficiaries
• Survivor benefit recipients for military retirement plans and similar arrangements
• Transfer-on-death or payable-on-death financial accounts
• Survivor beneficiaries for investment or brokerage accounts
• Co-tenants under a joint tenancy with right of survivorship (JTWROS) title or the beneficiary of a transfer-on-death deed (TODD)
• Life insurance policy beneficiaries

These designations should be reviewed periodically along with the other components of your estate plan. You should watch out not only for changes but also for possible conflicts between other documents.
