New Mexico adopted the Uniform Trust Code in 2003, making it one of the earlier Western states to do so. As a community property state, New Mexico has unique trust funding considerations that affect married couples. The state has also adopted the Uniform Trust Decanting Act, providing modern tools for updating outdated trust provisions. New Mexico has no state estate tax or inheritance tax. The New Mexico Trust Code is found at N.M.S.A. Sections 46A-1-101 and following.
This guide applies to both revocable and irrevocable trusts in New Mexico.
Where New Mexico trust law lives
New Mexico's trust statutes are codified at N.M.S.A. Sections 46A-1-101 and following. The code follows the standard UTC structure. The Uniform Trust Decanting Act provides a comprehensive framework for moving trust assets into new trusts with different terms.
Accounting and notice requirements
New Mexico follows the standard UTC notice framework. Trustees must notify qualified beneficiaries within 60 days of accepting trusteeship of an irrevocable trust. Annual accounting to qualified beneficiaries is required under the default rules. While the trust is revocable and the trust creator is alive and competent, the trustee's duties run primarily to the trust creator.
Trustee duties
New Mexico trustees must administer the trust in good faith, following the trust's terms and purposes, and in the interests of the beneficiaries. All standard UTC duties apply. Compensation follows the trust instrument first, with reasonable compensation as the default.
What makes New Mexico different
Community property state. New Mexico is one of nine community property states. Most property acquired during marriage is considered community property owned equally by both spouses. When funding a trust, you need to determine whether each asset is community property or separate property. Transferring community property into one spouse's separate trust requires the other spouse's consent. Getting the classification wrong can create disputes and unintended tax consequences. The upside: community property receives a full stepped-up basis at the first spouse's death, which can be a significant tax benefit.
Uniform Trust Decanting Act. New Mexico adopted one of the most comprehensive decanting frameworks in the West. This allows trustees to distribute assets from an existing trust into a new trust with updated terms without going to court.
No state estate tax or inheritance tax. New Mexico does not impose any state-level death taxes. Only the federal estate tax applies to estates exceeding the federal exemption.
Standard UTC modification tools. New Mexico provides nonjudicial settlement agreements, court modification for changed circumstances, and modification by consent.

The most common New Mexico trust mistakes
Not funding the trust. The most common trust mistake: assets not in the trust remain subject to probate.
Ignoring community property classification. Failing to properly account for community property when funding a trust can create ownership disputes and unintended tax consequences.
Missing the 60-day notice deadline. When a trust becomes irrevocable, the trustee must notify qualified beneficiaries within 60 days.
Not knowing about the decanting act. Families with older trusts may not realize they can update provisions through decanting rather than going to court.
When to talk to an attorney
You should consult a New Mexico trust attorney if you need help understanding how community property affects your trust, if you are interested in using the decanting act, if you have been named as trustee and need to understand your obligations, or if you recently moved to New Mexico from a common law property state.
