N.M. Stat. § 45-3-815
Administration in more than one state; duty of personal
representative.
A. All assets of estates being administered in New Mexico are subject to all claims,
allowances and charges existing or established against the personal representative
wherever appointed.
B. If the estate, either in New Mexico or as a whole, is insufficient to cover all family
exemptions and allowances (as determined by the law of the decedent's domicile), prior
charges and claims, after satisfaction of the exemptions, allowances and charges, each
claimant whose claim has been allowed, either in New Mexico or elsewhere in
administrations of which the personal representative is aware, is entitled to receive
payment of an equal proportion of his claim. If a preference or security in regard to a
claim is allowed in another jurisdiction but not in New Mexico, the creditor so benefited
is to receive distributions from local assets only upon the balance of his claim after
deducting the amount of the benefit.
C. In case the family exemptions and allowances, prior charges and claims of the
entire estate exceed the total value of the portions of the estate being administered
separately, and New Mexico is not the state of the decedent's last domicile, the claims
allowed in New Mexico shall be paid their proportion if local assets are adequate for that
purpose, and the balance of local assets shall be transferred to the domiciliary personal
representative. If local assets are not sufficient to pay all claims owed in New Mexico in
the amount to which they are entitled, local assets shall be marshalled so that each
claim allowed in this state is paid its correct proportion as far as possible, after taking
into account all distributions on claims allowed in New Mexico from assets in other
jurisdictions.
