New Mexico guide

New Mexico county Probate Courts can handle informal probate, while District Courts have broader jurisdiction including contested matters. Small-estate personal-property affidavits are a separate statutory option. Disputes or other limits on county probate jurisdiction can change where a case belongs.

Ask whether informal county probate is available, whether District Court is required, and whether a no-tax-due certificate filing is needed.

New Mexico county Probate Courts have limited informal-probate jurisdiction. A contested estate or a matter beyond that authority can belong in District Court instead. A personal-property successor affidavit is another procedure, not a county-court appointment. Clarify whether the estate needs authority to administer or only collection of a qualifying asset, and whether disagreements or land interests affect the route, before choosing the most convenient set of forms.

New Mexico does not currently impose a state estate tax for 2026 deaths and does not currently impose a separate inheritance tax for 2026 deaths. New Mexico's revenue guidance still describes an estate-return filing and certificate-of-no-tax-due process when a federal Form 706 is filed. This does not mean the inheritance or its future earnings are exempt from federal estate, income, or capital gains tax. Property and a decedent connected to another state can require another state's review. Older deaths can have different rules.

New Mexico Revenue says its estate tax is phased out, but instructs filing a state return with a required federal Form 706 for a certificate of no tax due.

Legal authority, tax reporting, and investing are different tasks. In New Mexico, ask the estate attorney to confirm the transfer route and notices, the CPA to review state and federal returns, and the financial advisor to discuss your own cash flow, retirement income, and risk. A simplified estate process is not a tax exemption or an investment recommendation.
