New Mexico: Affidavit of Surviving Joint Tenant Title-Clearance Requirements
The short answer
New Mexico recognizes joint tenancy when the creating instrument uses the statutory joint-tenancy or survivorship language. But current statewide property, probate, and county-record statutes prescribe no surviving-joint-tenant affidavit, signer, contents, death-certificate attachment, deadline, or special affidavit effect. A death certificate may be recorded with the county clerk as a convenience, but NMSA 1978 § 14-8-9.1(F) expressly says nobody is required to record one to effect a change of title or interest in property.

| Covered survivorship title | Joint tenancy created by express joint-tenancy or survivorship language (NMSA 1978 §§ 47-1-16, 47-1-35 to -36); otherwise co-ownership defaults to tenancy in common (§ 47-1-15) |
|---|---|
| Instrument or filing | No survivor-specific statewide affidavit. A death certificate may be recorded with the county clerk as a convenience, but recording is not required to change title or a property interest (§ 14-8-9.1(F)) |
| Who may sign or file | No statutory survivor-affiant or filer class; § 14-8-9.1(F) does not designate who may present an optional death certificate |
| Required contents | No survivor-affidavit fields prescribed. The optional instrument is the death certificate itself; no property description, creating-deed reference, or survivor recital is stated in § 14-8-9.1(F) |
| Death evidence | Recorded death certificate is permitted as a convenience; no certified-copy requirement or mandatory attachment to an affidavit in the surveyed provisions (§ 14-8-9.1(F)) |
| Execution formalities | No statewide survivor-affidavit oath, acknowledgment, notary, witness, or personal-knowledge rule; the reviewed statutes create no such affidavit |
| Office and deadline | Optional death-certificate recording is with the county clerk; no post-death deadline stated (§ 14-8-9.1(F)) |
| Statewide companion filings | No statewide tax, assessor, ownership-report, or other companion filing prescribed for the optional death-certificate route |
| Recording effect | Recording is expressly a convenience and is not required to effect a title or property-interest change (§ 14-8-9.1(F)); no survivor affidavit has a statutory vesting, notice, indexing, or evidentiary effect |

New Mexico uses the creating instrument, not a survivor affidavit
New Mexico's property statutes determine whether survivorship exists from the
creating instrument. Section 47-1-15 makes common ownership the default, while
§ 47-1-16 treats an instrument using “as joint tenants,” survivor language, or
“right of survivorship” as prima-facie evidence of joint tenancy and conclusive
for purchasers or encumbrancers for value.
Sections 47-1-35 and 47-1-36 reinforce that structure. A conveyance to grantees
“as joint tenants” runs to the survivor and the survivor's heirs and assigns,
and a real-property joint tenancy must be expressly declared in the will or
conveyance under the listed creation routes.
The current statewide property, probate, and county-record chapters do not
create an “affidavit of surviving joint tenant.” They prescribe no statutory
affiant, recitals, legal description, creating-deed reference, certified death-
record attachment, execution formalities, filing deadline, or special affidavit
effect for ordinary joint-tenancy title.
Optional county-clerk death-certificate recording
NMSA 1978 § 14-8-9.1(F) permits death certificates to appear in the county
clerk's recorded records and restricts third-party purchasing, copying, or
digitizing for 50 years after death. Its title consequence is equally explicit:
recording a death certificate is a convenience, and no person is required to
record one to effect a change of title or interest in property.
The section states no certified-copy requirement, property-description field,
survivor recital, attachment to an affidavit, or deadline. It also does not give
the recorded death certificate a special vesting, notice, or evidentiary effect.
What trips people up
Optional means optional. A county may accept a death certificate for the
record, but state law expressly says the recording is not required to change
title or a property interest.
General recording law does not create a survivor affidavit. The fact that
an instrument may be accepted by a county clerk does not supply the signer,
contents, execution rules, or title effect absent from the surveyed statutes.
Common questions
Can an affidavit create survivorship if the deed is silent? No. Sections
47-1-15, 47-1-16, 47-1-35, and 47-1-36 make the creating instrument control the
ownership form.
Must the optional death certificate be certified? Section 14-8-9.1(F)
refers to a death certificate but states no certified-copy requirement for the
optional county-clerk recording described there.
Does recording the certificate conclusively clear title? The statute does
not give it that effect. It calls recording a convenience and says it is not
required to effect a change of title or property interest.
