Unlike a spouse, an unmarried partner has no automatic inheritance rights under New Mexico law. If you die without a will, the state's intestate succession law passes your assets to biological relatives in a fixed order that does not include your partner. The only way to make sure your partner receives what you intend is to create legal documents that direct those assets deliberately.
A will is the starting point
A will is the foundational document for directing assets to an unmarried partner. It names your partner as the beneficiary of your estate, appoints them as personal representative to manage the settlement process, and records your specific wishes about how your property should be distributed.
A will controls assets that pass through your probate estate. That means property titled in your name alone without a beneficiary designation or survivorship feature. For many people, this includes personal property, vehicles, bank accounts without POD designations, and any real estate not held in a trust or with a survivorship feature.
One important limitation: New Mexico's intestate succession law applies when there is no will. But even with a will, biological family members may have certain rights depending on how the estate is structured. Working with an estate planning attorney ensures the will is drafted in a way that holds up and accomplishes what you intend.
Beneficiary designations handle retirement accounts and life insurance
Retirement accounts, including 401(k) plans and IRAs, and life insurance policies pass directly to whoever is named on the beneficiary designation form. These assets bypass the will entirely and do not go through probate. Naming your partner as the primary beneficiary on each of these accounts is often the single most impactful step an unmarried person can take to protect their partner financially.
The process is straightforward: contact each financial institution and insurance company, request a change of beneficiary form, and designate your partner. Keep copies of the completed forms and review them periodically, because an outdated designation can send assets to the wrong person regardless of what your will says.
Payable-on-death designations on bank accounts
Most banks allow you to add a payable-on-death designation to a checking or savings account. At your death, the account passes directly to the named person outside of probate. Adding your partner as the POD beneficiary on your primary accounts ensures they have immediate access to funds without waiting for the probate process to conclude.
A revocable living trust for comprehensive protection
A revocable living trust can hold your assets during your lifetime and distribute them to your partner at death without probate. The trust is also useful during incapacity: your partner, if named as successor trustee, can step in and manage trust assets immediately without any court process.
For couples with significant assets, real estate, or a desire for privacy, a trust often provides more comprehensive protection than a will and beneficiary designations alone. The trust must be funded, meaning assets must be transferred into it, to provide these benefits.
Real estate requires specific attention
If you own a home or other real estate, how it's titled determines what happens to it at your death. Property held as joint tenants with right of survivorship passes automatically to the surviving partner without probate. Property titled in your name alone passes through your estate. A trust can also hold real estate and distribute it according to its terms. Choosing the right titling or ownership structure for shared real estate is one of the most important decisions an unmarried couple can make.
