New Mexico Statute of Limitations on Business Debt: What Creditors Owed by an Albuquerque Company Need to Know

A creditor owed by a New Mexico company has six years to sue on a contract in writing, four years on an open account or an unwritten contract, four years on a sale of goods, and fourteen years on a judgment. The one most trade creditors live under is the four years, because most receivables are a running account of invoices, not a signed instrument.

New Mexico is more generous than that summary sounds, in two places more generous than any other state in the West. An open account is measured from its last item, not invoice by invoice, and a partial payment or a signed admission brings a claim back to life, even one the statute has already run on. Below is what the statutes say, what moves the clock, and what to do with an Albuquerque account that has gone quiet. Laws vary by state and this is general information, not legal advice.

Key takeaways

• NMSA 1978, Section 37-1-3(A) gives six years to an action founded upon any bond, promissory note, bill of exchange or other contract in writing. Section 37-1-4 gives four years to one founded upon an account or an unwritten contract, which is where most trade receivables land.
• Section 37-1-6 says that where there is an open current account the cause of action accrues on the date of the last item in it, as proved at trial. On a live account the four years run from the last sale or payment, not from each invoice.
• Under Section 37-1-16 a contract claim is revived by any partial or installment payment, or by a written admission that the debt is unpaid or a new promise to pay signed by the debtor, and the period runs again from that date. Nothing in the section limits that to claims still inside the period.
• A contract for the sale of goods gets four years under Section 55-2-725, and the original agreement can cut that to as little as one year but cannot extend it. The claim accrues at the breach whether or not the seller knew of it.
• A New Mexico judgment can be sued on for fourteen years under Section 37-1-2 and, since the 2021 amendment, a revived judgment is not enforceable after fourteen years from the original one. The judgment lien under Section 39-1-6 carries the same fourteen year limit.
• If you have a signed agreement that allows for collection costs or collection agency fees, those charges may be included in the amount sought during collection. If legal action becomes necessary, recoverable fees and costs are determined under applicable New Mexico law and are ultimately subject to the court.

How long do you have to sue on a business debt in New Mexico?

Direct answer

Six years on a contract in writing under NMSA 1978, Section 37-1-3(A). Four years on an account or an unwritten contract under Section 37-1-4, which covers an oral agreement and an open account. Four years on a contract for the sale of goods under Section 55-2-725. Fourteen years on a judgment of a New Mexico court under Section 37-1-2.

New Mexico draws the line between written and unwritten obligations, the line Idaho and Utah draw and Oregon and Washington do not. Section 37-1-3(A) gives six years to an action founded upon any bond, promissory note, bill of exchange or other contract in writing. Section 37-1-4 gives four to those founded upon accounts and unwritten contracts, along with everything the chapter does not otherwise provide for. A signed credit agreement or a promissory note: six years. A stack of invoices nobody signed: four.

For a trade creditor the honest answer is that most New Mexico accounts are four year accounts. An invoice is a bill, not a contract the customer signed. Plan every account around four years and treat the extra two under 37-1-3 as something your signed paperwork may earn you. Section 37-1-17 also leaves alone any shorter period a particular statute sets, and the lien deadlines on a construction project are the obvious example, covered in the construction collections guide.

Is a New Mexico open account measured from each invoice or from the last item?

Direct answer

From the last item. Section 37-1-6 provides that where there is an open current account, the cause of action is deemed to have accrued on the date of the last item in the account, as proved at trial. The four years under Section 37-1-4 run from the last charge or credit on a running account, not from each invoice.

This is the section that makes New Mexico different from Idaho and Colorado, where the conservative reading is that each invoice ages on its own. New Mexico has had a last item rule since 1880, and the annotations describe an open account as one single and indivisible liability arising from a connected series of reciprocal debits and credits. While the account is open and current, with sales and payments moving both ways, the period is measured from the most recent entry.

Two cautions from the same annotations. The account has to be a genuine running account, kept in writing, with reciprocal entries. A loan the borrower makes payments on does not become an open account, and a fixed term lease is not one either. And the phrase in the statute is as proved on the trial, which means the ledger is the evidence. A credit manager in Rio Rancho who can print a clean statement with dated charges and credits is far better placed than one whose last item lives in a salesperson's memory. And a finance charge you post on your own side is not an item the customer put there.

Does a signed credit application give an Albuquerque account six years or four?

Direct answer

It depends on what the writing says. Plan on four. Section 37-1-4 puts an account and an unwritten contract at four years, and an open account built on invoices and a course of dealing is usually that. A signed instrument that itself sets out the obligation to pay is what Section 37-1-3(A) rewards with six.

Controllers in Albuquerque ask me this more than anything else, and there is no crisp answer. Section 37-1-3(A) speaks of a contract in writing. A signed credit application that states the terms of sale and an agreement to pay gives a creditor a real argument that the obligation rests on a writing. One that only collects trade references and a tax identification number is a writing too, but the promise to pay does not live in it. Whether a particular application crosses that line is a question for a New Mexico attorney with the document in hand.

Three practical points follow. Get the credit application signed, with the paragraph that says the customer agrees to pay on the stated terms, because that sentence turns a form into a contract. Keep the signed copy where you can find it in six years. And do not let the possibility of six years change how you work the account. In New Mexico the better protection for a running account is Section 37-1-6, not the signature.

Does a sale of goods get a different period in New Mexico?

Direct answer

Section 55-2-725 requires an action for breach of any contract for sale to be commenced within four years after it accrued, and the original agreement may reduce that to not less than one year but may not extend it. The claim accrues when the breach occurs, regardless of the aggrieved party's lack of knowledge of the breach.

New Mexico's Uniform Commercial Code, Article 2, governs contracts for the sale of goods, which covers most of the distributors, manufacturers, oilfield suppliers and building material dealers reading this. Where Section 37-1-3 would give a signed supply agreement six years, Section 55-2-725 gives a contract for sale four, so product sold on a signed master agreement to a customer in Hobbs or Farmington is on the four year clock.

Three things in the section deserve attention. The period can be shortened by agreement, down to one year, and the original agreement controls, so a master supply agreement signed years ago can do exactly that. It cannot be extended by agreement, so a clause in your own terms claiming six years does nothing. And the claim accrues at the breach regardless of the seller's knowledge, which for a nonpayment means the due date. How the four years on goods interacts with the last item rule on a running account is one to put to counsel rather than assume.

Does a payment or a written admission restart the New Mexico clock, even after it has run?

Direct answer

Yes. Section 37-1-16 says a cause of action founded upon contract is revived by any partial or installment payment, or by a written admission that the debt is unpaid or a new promise to pay signed by the debtor, and accrues again on that date. New Mexico courts have applied it after the period had run.

This is the section that makes New Mexico the most forgiving state in the West for a creditor who waited too long. Most states let a payment or a signed acknowledgment restart a running period and go quiet on whether anything revives an expired claim. Washington went the other way in 2019 and now says nothing does. New Mexico's statute uses the word revived, and the annotations collect decisions since 1900 holding that it applies equally to admissions made after the statute has run, that an unconditional written admission that the debt is unpaid is enough without any promise to pay, and that the admission works even where the debtor adds that he is unwilling to pay.

Read the section carefully, because its two halves have different requirements. A partial or installment payment revives the claim on its own. An admission or a new promise has to be in writing and signed by the party to be charged. A controller's email confirming the balance is that kind of writing, and whether a typed name is a signature is a question for a New Mexico attorney, so get the email anyway. The phone call promising a check is worth nothing here.

Two cautions. Apply payments the way the customer directed, because a new order payment your system posts to the oldest invoice is an entry you may have to defend. And a letter that denies owing the debt revives nothing. When a customer in Santa Fe offers a small payment to buy time, take it, document it, and keep working the account. The payment helps you. The time does not.

What if the customer left New Mexico or the claim arose in another state?

Direct answer

Section 37-1-9 stops the clock for any time after the debt arose during which the debtor is absent from the state or concealed within it. New Mexico has no general borrowing statute; its courts have treated limitation periods as procedural and applied New Mexico's own periods even where another state's substantive law governs the contract.

New Mexico's tolling rule is broad on its face. Section 37-1-9 excludes any time, after the debt is incurred or a judgment entered, during which the debtor has been absent from the state or concealed within it. Read that narrowly. A company with a registered agent on file can be served while its owner is in Colorado, and a company that moved its office is not concealing itself. Treat tolling as a question for a New Mexico attorney, not as time you have.

On the out of state question, New Mexico is the reverse of Idaho and Utah, whose borrowing statutes close the door on a claim already barred where it arose. Chapter 37 has no such section, and its annotations collect decisions treating a statute of limitations as procedural, so New Mexico's periods apply in a New Mexico court even where another state's law governs the contract. For an out of state creditor chasing an Albuquerque customer, the working assumption is New Mexico's four or six years, with the last item and revival rules. Where more than one state could hear the claim, ask counsel which forum is right before anyone files.

How long can a New Mexico judgment be enforced?

Direct answer

Fourteen years from the date of the judgment under Section 37-1-2, and not afterward. Since the 2021 amendment, a revived judgment is not enforceable after fourteen years from the original one. Under Section 39-1-6 a transcript of judgment filed with the county clerk is a lien on the debtor's real estate there, enforced for not more than fourteen years.

Fourteen years is longer than any contract period in the state. The catch is that it is a ceiling. Section 37-1-2 used to leave room for a creditor to sue on the judgment near the end of the period and start again, which is how an Idaho creditor can hold a judgment indefinitely. The 2021 amendment closed that: a judgment obtained by any means of revival is not enforceable after fourteen years from the original. A New Mexico judgment is good for fourteen years and then it is done.

The lien works the same way. Under Section 39-1-6 a money judgment of the district court or the metropolitan court is docketed by the clerk, and a transcript filed with the county clerk where the land sits is a lien on the debtor's real estate from that date, enforced for not more than fourteen years. A creditor with a judgment against an Albuquerque company that owns its shop should file the transcript in Bernalillo County and plan on nothing beyond year fourteen.

Can you take a business debt to small claims court in Albuquerque?

Direct answer

New Mexico has no separate small claims court. The magistrate courts hear civil actions where the debt or sum claimed does not exceed $10,000 exclusive of interest and costs under Section 35-3-3, and in Bernalillo County the Metropolitan Court has that same civil jurisdiction under Section 34-8A-3. Larger claims go to district court.

The lower courts in New Mexico are the magistrate courts in most counties and, in Bernalillo County, the Metropolitan Court, which took the magistrate court's place for Albuquerque. Section 35-3-3 gives magistrates jurisdiction in civil actions where the debt or sum claimed does not exceed ten thousand dollars, exclusive of interest and costs, including actions in contract, and Section 34-8A-3 gives the Metropolitan Court the same civil jurisdiction within the county. Above that figure the case belongs in district court.

Two cautions before you file. Whether your company can appear through an officer rather than a lawyer is governed by the court rules, so ask before the filing fee is paid. And a filing is public, and a customer with a story about the goods will tell it to the judge. For most accounts in the range we handle, from $1,000 to hundreds of thousands of dollars, the right first step is still a professional collection effort.

Once a claim moves toward court the interest question gets decided by the contract and by the interest statutes: Section 56-8-3 caps interest at fifteen percent a year on money due by contract where no written contract fixes a rate, Section 56-8-5 applies the same ceiling to an open account from thirty days after the last article or service unless a higher rate was agreed, and Section 56-8-4 sets eight and three fourths percent on a judgment unless it rests on a written instrument with its own rate. An agency effort costs nothing unless it collects, and it keeps the courthouse in reserve.

Does a collection agency need a New Mexico license?

Direct answer

Yes, for the business of collecting claims for others. Section 61-18A-5 of the Collection Agency Regulatory Act makes it unlawful to conduct a collection agency within the state, or to collect or solicit the collection of any claim for another, without first obtaining the licenses the Act requires from the Financial Institutions Division of the Regulation and Licensing Department.

The Collection Agency Regulatory Act is Chapter 61, Article 18A of the NMSA 1978, administered by the Financial Institutions Division. Section 61-18A-5 is written broadly: no person shall conduct a collection agency in the state, collect claims for others, or solicit the right to collect any claim for another, without the required licenses, and Section 61-18A-15 requires a surety bond before a license issues. The Division says its licenses cover all third party debt collection in New Mexico.

There is a wrinkle a commercial creditor should know about. The Act's definitions in Section 61-18A-2 describe a debt as an obligation arising from a transaction primarily for personal, family or household purposes, and a debtor as a natural person, while the licensing section speaks of any claim. How those fit together for a purely commercial account is a question for a New Mexico attorney. What a creditor can do is ask the agency what it holds.

That is why it is important to use a certified commercial collection agency. Sven works with C2C Resources, which is certified by the Commercial Law League of America, endorsed by the International Association of Commercial Collectors, carries a $500,000 surety bond, and holds collection licenses in the states that require them. C2C has collected more than $1 billion for 35,000+ clients since 2002, and its collectors average more than 25 years in the work.

What should a creditor do with an Albuquerque account right now?

Direct answer

Print the statement of account and find the last real item, because that is the accrual date on a running account. Sort the paperwork into signed and unsigned, which decides six years or four. Note the last payment and any signed admission, since either revives the claim. Read both sides' terms for a goods clause. Then place it early.

Here is the order I would work a New Mexico account in. First, the ledger. Print a clean statement of account with every dated charge and credit, because Section 37-1-6 measures the period from the last item as proved at trial, and the statement is the proof. The last real sale or payment is the day the four years started.

Second, the documents. Sort the credit application, purchase orders and invoices into what the customer signed and what it did not. That sort is the difference between Section 37-1-3 and Section 37-1-4. Third, the revival evidence: the date and amount of the last payment, and any email or letter in which the customer admitted the balance or promised to pay, because under Section 37-1-16 either one restarts the period. Put those in the file now.

Fourth, the terms. Read your own credit agreement for interest and service charges, and read the customer's paper for a limitations clause on goods under Section 55-2-725.

Fifth, decide. New Mexico gives a creditor more second chances than its neighbors, and that is exactly why accounts there get worked too slowly. A two year old Albuquerque account has lost most of its leverage, whatever the statute still allows. The neighboring states are in the Colorado, Utah, Nevada, Idaho, Oregon and Washington guides, and the full statute of limitations by state table covers a customer anywhere else.

Frequently asked questions

Is the New Mexico statute of limitations different for a business debt than for a consumer debt?

NMSA 1978, Sections 37-1-3 and 37-1-4 apply to contracts generally, business or consumer. What differs on a commercial account is the paperwork: a signed credit application, purchase orders and a running account decide whether the claim is founded on a contract in writing, whether it is an open account measured from the last item, and whether the sale of goods rule applies instead. We handle commercial (B2B) claims only, so this article is written for the creditor side of a business account.

Our Albuquerque customer never signed anything. How long do we have in New Mexico?

Four years. Section 37-1-4 gives four years to an action founded upon an account or an unwritten contract, which is where an oral agreement and an account built on invoices land. A sale of goods is also four years under Section 55-2-725. If the account is an open current account, Section 37-1-6 measures the four years from the date of the last item in it, so the clock runs from the last sale or payment, not from the first unpaid invoice.

The customer sent a small payment last month. Did that restart the New Mexico clock?

Yes. Under Section 37-1-16 a cause of action founded upon contract is revived by any partial or installment payment, and it is deemed to have accrued on the date of that payment. The writing requirement in that section attaches to an admission or a new promise, not to a payment. Record what the payment was for and how it was applied. New Mexico courts have applied the section to payments and admissions made after the period had already run, but whether that saves a particular account is a question for a New Mexico attorney.

Can we charge interest on a past due New Mexico invoice if our terms never mention it?

New Mexico sets a statutory ceiling on interest for money due by contract and for open accounts where no written contract fixes a rate, so a charge inside that ceiling is possible on an invoice that was due on receipt. Where you extended credit terms such as net 30, any service charge or interest belongs in the written credit agreement the customer signed. A charge that appears for the first time on a past due statement is the first thing a customer disputes.

What size of claim can you help with?

We work commercial claims from $1,000 to hundreds of thousands of dollars, under 120 days past due, on contingency, so there is no fee unless we collect. Commercial (B2B) collections only. We do not collect consumer debt. That covers accounts owed by companies in Albuquerque, Rio Rancho, Santa Fe, Las Cruces, Farmington, Roswell, Hobbs, Carlsbad and the rest of New Mexico. Yes, we collect internationally. Talk to us about your specific account.
