What happens if you pay back taxes on inherited land but aren’t listed as owners on the deed?

Short answer: Paying delinquent property taxes does not automatically make you the legal owner in New Mexico. It can protect the property from a tax sale and may give you a reimbursement claim or other equitable remedies, but you usually need a deed or a court order (for example through probate or quiet-title) to hold title. This page explains the likely consequences, your rights, and practical next steps.

Detailed answer — how New Mexico law treats tax payments on property you don’t own

1. Legal title vs. tax payments: Legal title to real property is established by recorded instruments (deeds) or by a court order transferring title (for example, in probate). Simply paying the property taxes does not create or transfer legal title in New Mexico. The person or entity shown on the county deed records remains the owner until title passes by deed, court order, or other recognized legal means.

2. Protecting the property from tax sale: If taxes are delinquent, paying them will stop or reverse the county’s efforts to sell the property for unpaid taxes. In that sense, paying delinquent taxes protects the property from immediate loss by tax sale. If you want to stop a pending tax sale, pay the county treasurer the amount demanded and get a receipt and written confirmation that taxes were brought current.

3. Reimbursement claims and equitable remedies: If you paid taxes to preserve the property for heirs or creditors, you may have a claim for reimbursement against the estate or against co-heirs who benefited. New Mexico courts may recognize equitable remedies (such as unjust enrichment or a lien for taxes advanced) in some circumstances, but those remedies do not substitute for a recorded title transfer. To enforce a reimbursement claim you may need to file a claim in probate or pursue a civil action.

4. Probate and nonprobate transfers: If the decedent’s estate has not been probated, the property remains in the decedent’s name for purposes of the deed records. To become owner you typically must either:

become the recorded owner by receiving a deed from the person(s) who hold title (for example, through probate distribution or a deed from the personal representative), or
obtain a court order (for example through probate distribution or a quiet-title action) declaring you the owner.

See New Mexico statutes covering probate and property transfer procedures (Title 45 and Title 7). For statutory text and procedures, consult the New Mexico Legislature site: https://www.nmlegis.gov (see generally Title 45 — Probate and Title 7 — Revenue and Taxation).

5. Risk of tax sale and what paying accomplishes: If you pay the delinquent taxes yourself you prevent the county from selling the tax lien or property for those unpaid taxes. If someone else pays the delinquent taxes and obtains a tax lien/deed under the county’s tax-sale process, they could eventually obtain a tax deed and possibly clear title if the statutory redemption periods lapse and they follow required procedures. Check your county treasurer’s rules and the New Mexico tax statutes at the state legislature site for the county’s specific foreclosure/tax sale rules.

6. Possible path to title after paying taxes: Paying taxes can help preserve property while you complete a legal route to title. Common next steps include opening probate (if estate administration is needed), asking the personal representative to include the tax payments and to transfer title, recording a deed signed by the holder of legal title, or filing a quiet-title action to resolve competing claims.

When paying taxes might give you stronger legal standing

If you are a named heir or beneficiary and you paid taxes to protect the family property, keep detailed records and receipts; the probate court may allow reimbursement or credit to you as an expense of the estate.
If the owner of record signed an agreement or deed promising to transfer title to you after you paid taxes, that agreement might create an enforceable contract — but you still should record a deed or obtain a court order to perfect title.
If you occupy and openly possess the property and meet statutory requirements for adverse possession, you might eventually obtain title through adverse possession. Adverse-possession claims are fact-specific and depend on statutory time periods and requirements in New Mexico, so consult an attorney.

Practical steps to protect your position

Obtain written receipts and record of payment. Get a detailed receipt from the county treasurer showing the parcel ID, amounts paid, and the date. Keep proof that you brought taxes current.
Check the deed and public records. Look up the parcel in the county clerk/recorder’s office to confirm the recorded owner, mortgages, liens, and whether a probate or other court action affecting title is open.
Confirm whether the estate has been opened in probate. If not, consider whether someone should open an estate administration. Probate transfers title in many situations.
Ask for a deed or written agreement. If co-heirs or a personal representative control title, request a quitclaim or other deed transferring their interest to you, and record it.
Consider a claim for reimbursement or an accounting. If you paid taxes for the benefit of an estate or co-heirs, you may be able to demand reimbursement through probate or a civil action.
Talk to a New Mexico real property or probate attorney. An attorney can advise on filing probate, preparing a deed, quiet-title or partition actions, and whether an equitable lien or other remedy applies.

What if someone else files a tax-sale or obtains a tax deed?

If a third party pays delinquent taxes and follows the county’s tax-sale procedures, they can obtain a tax lien and may be able to foreclose or obtain a tax deed after statutory notice and redemption periods. Paying the delinquent taxes yourself before a sale usually protects the property from that specific tax-sale threat. Contact your county treasurer immediately if a tax-sale notice has been filed.

Helpful Hints

Always get and keep written receipts for any tax payments; the county treasurer’s receipt is your best proof.
Search county deed, mortgage and probate records online or at the county clerk’s office before you pay more money.
If you are an heir, open a probate case (or check whether one is open) so payments can be handled as estate expenses and you can seek reimbursement.
If you expect to receive title, insist on a recorded deed transferring title to you rather than relying on informal promises.
If someone threatens to buy the tax lien or file a tax-sale, act quickly — counties follow statutory deadlines that can result in loss of title if taxes aren’t paid.
Consider filing an affidavit of heirship for small, uncontested estates — this can help marketability but does not replace probate where probate is required.
When in doubt, consult a New Mexico attorney experienced in probate or real property; small mistakes can cost a property.
