What the statute actually says
“Thirty days after the death of a decedent, any person indebted to the decedent or having possession of tangible personal property or an instrument evidencing a debt, obligation, stock or chose in action belonging to the decedent shall make payment of the indebtedness or deliver the tangible personal property or an instrument evidencing a debt, obligation, stock or chose in action to a person claiming to be the successor of the decedent … The affidavit made pursuant to this section may not be used to perfect title to real estate.”
(NMSA 1978, § 45-3-1201)
The dollar limit
The value of the entire estate, wherever located, less liens and encumbrances, must not exceed $50,000: NMSA 1978, § 45-3-1201(A). A separate, distinct affidavit (NMSA 1978, § 45-3-1205, “Affidavit of Surviving Spouse”) lets a surviving spouse claim only the decedent’s primary residence, up to $500,000 assessed value, but requires a 6-month wait and is filed with the county clerk rather than delivered privately: a different instrument, not a spousal tier of this one.
The form
No official statewide fillable form found. New Mexico’s judicial-branch “Affidavits” forms library does not list a small-estate/collection-of-personal-property affidavit; the official NM Courts self-help probate guide instead tells filers to “check with your local Probate Court to find out where to get the forms.”
What could not be verified
The true primary source, nmonesource.com, returned HTTP 403 on every URL tried this session (now requires login). The $50,000 limit, 30-day wait, notarization requirement, and personal-property-only scope were instead confirmed from an official New Mexico judicial-branch document read in full this session: the “NM District Court Self Help Guide” (nmcourts.gov), which states verbatim: “The affidavit must be signed by the person entitled to receive the decedent’s property and notarized,” and cites § 45-3-1201 by name. The statute’s exact operative wording was cross-checked against codes.findlaw.com (secondary) since nmonesource.com could not be reached directly.
When this route is the wrong one
- The estate is over the limit. Full administration applies, and using the small-estate route anyway does not make it valid.
- There is real estate and this route does not reach it. A house needs the instrument that can actually transfer title.
- Someone disputes it. These procedures assume agreement; a contested estate belongs in front of a judge.
- Debts exceed assets. Paying the wrong creditor first can make you personally liable.

General information drawn from state statutes and official court materials, not legal advice. Probate and small-estate procedure is STATE law and differs in every state; thresholds, waiting periods and forms change, and every figure here is sourced and dated. Using the wrong instrument, or using one before its waiting period has run, can make a transfer ineffective and can expose the person who signs the affidavit to personal liability.
