The New Mexico Default That Can Force the Company to Write a Cheque

Two owners reviewing a contribution schedule at a workbench.
In New Mexico the contribution schedule is the ownership record. The state does not keep one.

Most guidance about operating agreements is written in the abstract. New Mexico gives a concrete reason to care, and it sits at section 53-19-37 of the state's Limited Liability Company Act. Unless the articles of organization or an operating agreement provide otherwise, a member of a company with perpetual existence may withdraw at any time on thirty days written notice to the other members. And unless those documents provide otherwise, the member who withdraws is entitled to receive, within a reasonable time, the fair market value of the limited liability company interest.

Read that twice. In a state that requires no operating agreement, the statute hands every member a put option against the company, exercisable on a month's notice, priced at fair market value, with no formula, no discount, no instalment schedule and no cap. The only thing that changes it is a written agreement saying something else.

That is the practical case for drafting in New Mexico, and it is stronger than the usual argument about governance hygiene. The general drafting patterns are covered in the operating agreement essentials guide; what follows is what New Mexico specifically does when your document is silent. The transactional version, with pricing and turnaround, is on the New Mexico operating agreement page.

New Mexico is a contribution-weighted state, not a per-capita one

This is where the common summaries get New Mexico wrong. The state is routinely described as splitting votes and money equally among members. It does not.

Votes follow capital. Section 53-19-17 provides that members who have contributed to the capital of the company vote in proportion to the value of their contributions, and that a reference to a vote of the members means the members holding a majority of the voting power. A member who contributed nothing but labour has, by default, no vote at all.

Profits follow capital too. Section 53-19-22 allocates profits and losses in the manner set by the articles or an operating agreement, and where neither provides for it, in proportion to the value of the members' respective contributions to capital. Sweat equity is invisible to that formula unless the contribution of services is valued and recorded.

Management is an articles question, not an agreement question. Under section 53-19-15, management is vested in the members unless the articles of organization vest it in one or more managers. Writing manager management into the operating agreement alone leaves the public record saying something different, which is the version a third party will rely on.

New members need everyone. Section 53-19-33 lets an assignee of an interest become a member only if the other members unanimously consent. One holdout blocks any admission, including the admission of an investor the majority has already signed a term sheet with.

Sole owners, and the document New Mexico expects you to keep

New Mexico does not publish member names. The articles of organization do not list owners or managers, and the state requires no annual report for a limited liability company, so nothing ever updates the public record. For a sole owner that privacy is the point, and it is also the problem: outside your own files there is no evidence anywhere that you own the company.

Section 53-19-19 assumes you will have that evidence. It requires the company to keep, at its principal place of business, a list of current and former members and managers with addresses, copies of the articles and amendments, tax returns and financial statements for the three most recent years, current and prior operating agreements with their amendments, and statements about capital contributions and the timing of contributions or withdrawals. The records statute is written as though a written operating agreement exists. Where one does not, the file has a hole in it that a bank, a lender or a buyer will find. Federal and practical consequences of running a one-owner entity are set out in the single-member LLC guide, with the state layer on the New Mexico single-member LLC page.

Ten Clauses, Each Displacing a Specific New Mexico Default

Nothing below is generic. Each clause exists because Article 19 already answers the question, and the statutory answer is usually not the one the founders had in mind.

1. The member schedule, which is the only ownership record that exists

List every member by legal name and address, with the percentage each holds. Because New Mexico publishes nothing about ownership, this schedule is what a bank verifies against, what a lender relies on and what a buyer diligences. Under the federal customer due diligence rule a bank must identify each individual holding twenty-five percent or more of the equity plus one control person before opening an account, and in New Mexico the operating agreement is the only document that can prove either.

2. Contributions, valued, because the value drives the votes

In most states the contribution schedule is bookkeeping. In New Mexico it is the voting register and the profit formula at once, because sections 53-19-17 and 53-19-22 both key off the value of contributions. Record cash amounts, describe property with an agreed value, and if a member is contributing services or a binding obligation to perform them, put a number on it. An unvalued service contribution is, in a default fight, a contribution of nothing.

3. Manager management, and the filing that has to match it

Decide whether members run the company or a manager does, then make the articles of organization say so, because section 53-19-15 puts the manager election in the articles. Inside the agreement, define the manager's authority, spending limits, term, removal procedure and compensation. If the structure changes later, the articles change with it through an amendment to the New Mexico articles, and the agreement should be amended on the same day.

4. Voting, and the member whose labour buys no vote

The default is proportional to contributed capital. That is right for a company funded in cash by investors and wrong for a company where one founder wrote the cheque and another did the work. Decide deliberately: per capita, capital weighted, profit weighted or class based. Then list the decisions that need more than a simple majority, such as admitting a member, incurring debt above a threshold, selling assets, changing the tax election, or amending the agreement itself.

5. Allocations, distributions and the tax that arrives first

Separate the allocation of taxable income from the payment of cash. Members of a company taxed as a partnership owe tax on allocated income whether or not any cash was distributed, so a tax distribution clause matters. Section 53-19-22 supplies only a residual allocation rule and no distribution policy at all, so if the agreement is silent the members can be taxed on profits they never received while the manager keeps the cash in the business.

6. Transfers, and the unanimity that already sits in the statute

New Mexico is unusually protective here: an assignee gets economic rights only, and becomes a member only with unanimous consent of the other members under section 53-19-33. Use it deliberately. Keep the consent requirement, then add what the statute lacks: a right of first refusal, a permitted-transfer carve-out for estate planning, and a mandatory purchase on death, divorce, bankruptcy or expulsion so that the interest does not sit permanently with someone outside the business.

7. Withdrawal, the clause that costs the most to leave blank

This is the New Mexico clause. Section 53-19-37 gives a member of a perpetual company the right to withdraw on thirty days written notice and to be paid fair market value within a reasonable time, unless the articles or the operating agreement provide otherwise. Companies that intend a lock-up must say so. Companies that accept the put option should still define it: a valuation method, a minority discount if one is intended, a payment schedule with interest, and a subordination clause so the payout cannot breach the company's loan covenants.

8. Dissolution, and who can trigger it

Section 53-19-39 dissolves a company on an event stated in the articles or the operating agreement, on the written consent of members holding a majority of the voting power, or by judicial decree. A majority of voting power in a contribution-weighted state means a majority of the money, so a single funder can wind up the business over the objection of the operators. Set your own threshold, add a deadlock mechanism, and know what the filing looks like on the New Mexico dissolution page before you need it.

9. Tax classification, recorded in the document

State the federal classification the members have agreed on: partnership, disregarded entity, S corporation on Form 2553 or C corporation on Form 8832. Then check the allocation clauses against it. An S corporation election tolerates only one class of stock, so the special allocations and preferred returns that a partnership agreement carries will break the election. New Mexico charges no franchise tax on a pass-through company and imposes no annual report, so the federal election is the decision that actually moves money.

10. Amendments in writing, because the statute allows nothing else

Section 53-19-2 defines the operating agreement as a written agreement together with that agreement as amended in writing. A New Mexico company cannot amend by handshake, and a course of dealing does not modify the document. Say what vote amends it, require signatures, keep a dated amendment log, and store it with the articles and the company's New Mexico certificate of good standing when one is obtained.

If you would rather not do this yourself, we prepare the articles, check name availability with the state, and file it for you. Or keep reading and file it on your own. This guide covers everything you need either way.

Privacy, Banking, and the Record New Mexico Does Not Keep

New Mexico is one of the few states where a limited liability company can be formed without any owner being named on a public document, and where no periodic filing later exposes them. The articles of organization require an organizer, a registered agent and a registered office. They do not require members or managers, and because the state imposes no annual report on a limited liability company, nothing updates the record.

That is a genuine advantage and a real operational burden. Every institution that would ordinarily read ownership off a state filing has to read it off your documents instead. A bank opening an account, a landlord signing a lease with a personal guarantee, a factor buying receivables, a title company insuring a purchase, a buyer's counsel in diligence: each of them will ask for the operating agreement, the member schedule and a resolution showing who has authority to sign.

Two habits make that painless. Keep an execution-ready certificate of authority, a short signed statement naming the person authorised to bind the company for a specific transaction, referenced back to the clause in the agreement that grants the power. And keep the agreement current, because the version in the bank's file becomes the version the bank relies on. Where the entity operates outside New Mexico, the same package supports registration in another state, and the registered office side of the record is covered on the New Mexico registered agent page.

Creditor Remedies and Fiduciary Standards, Read Honestly

Section 53-19-35 is short. On application by a judgment creditor of a member, the court may charge that member's interest with payment of the unsatisfied amount of the judgment, and to the extent charged the creditor has no more rights than an assignee would have. That is the whole of it. There is no sentence declaring the charging order an exclusive remedy, and no sentence permitting or prohibiting foreclosure.

Owners should plan around that silence rather than assume it favours them. States that have amended their acts in the last decade, including Ohio, Oklahoma and North Dakota, say expressly that the charging order is the sole remedy and that the interest cannot be foreclosed. New Mexico says neither, which leaves the question to the courts. The practical response is not to rely on the statute alone: use transfer restrictions that bind any transferee, keep distributions discretionary rather than formulaic, and give the remaining members a redemption right that can be exercised before an outsider takes the economics.

On conduct, section 53-19-16 protects a member or manager from liability for an act or omission unless it amounts to gross negligence or wilful misconduct. That is a floor for liability, not a licence, and it does not answer questions about self-dealing, competing ventures or corporate opportunity. Because Article 19 does not spell out a duty of loyalty the way the newer uniform acts do, New Mexico agreements should do the work themselves: name the permitted conflicts, require disclosure and disinterested approval for related-party transactions, and state whether members may compete.

Five Mistakes New Mexico Owners Keep Making

Each of these has a statutory cause, and each is cheaper to fix at formation than at exit.

Mistake 1: Assuming the template's equal-split defaults match New Mexico

Templates written against the uniform acts assume per-capita voting and equal distributions, then leave the allocation clause thin because the default is thought to be harmless. In New Mexico the default is contribution weighted, so a thin clause hands control and cash to whoever put in the most money. If the founders intended equal partners, the agreement has to say so; the statute will not.

Mistake 2: Relying on an oral understanding, which does not exist here

New Mexico defines an operating agreement as a written agreement. An oral understanding between two members is not an operating agreement under section 53-19-2, so it does not displace anything in Article 19. Members who believe they have agreed to equal splits, a lock-up or a buyout formula, and have only agreed verbally, are governed by the statute in full. This is the sharpest difference between New Mexico and its neighbours.

Mistake 3: Putting manager management in the agreement but not the articles

Section 53-19-15 vests management in the members unless the articles of organization vest it in managers. An agreement that appoints a manager while the articles stay silent creates a mismatch that only surfaces when a third party relies on the public filing. Amend the articles and the agreement together, and treat any change of manager, registered office or agent as one event rather than three, using the New Mexico agent change as the checkpoint.

Mistake 4: Looking for the filing fee, or paying one

There is no operating agreement filing in New Mexico. No form, no portal step, no fee. Anyone quoting a state charge for it is quoting a charge that does not exist. Filing it would also destroy the privacy that led many owners to New Mexico in the first place, since it would publish member names, capital values and buyout formulas. The state fee you do pay is $50 to form the company, and there is no recurring report.

Mistake 5: Leaving section 53-19-37 exactly as the legislature wrote it

Most founders would never agree to a thirty-day exit at fair market value if it were put to them in a negotiation. Most New Mexico founders have agreed to exactly that, by leaving the point out of their agreement. Either accept the right and define how it is priced and paid, or displace it with a lock-up and a formula. What should not happen is discovering the provision for the first time in a demand letter.

Three New Mexico Companies, and What the Statute Decided

Composite cases built from the disputes that recur in this state.

Example 1: A Santa Fe gallery where the working partner had no vote

Two members opened a gallery. One contributed $220,000 in cash, the other contributed full-time management and $5,000. They wrote nothing down. Under section 53-19-17 the vote was proportional to contributed capital, so the cash member held roughly ninety-eight percent of the voting power and the working member effectively none. When the two disagreed about a second location, there was no deadlock to break. The agreement they eventually signed valued the service contribution at $150,000 and moved the split to sixty forty, but the first two years ran on the statute.

Example 2: A Las Cruces pecan operation and a thirty-day notice

Four members owned a pecan growing and packing company with about $2.6 million of book value in orchards and equipment. One member, holding twenty percent, sent a written notice of withdrawal and demanded fair market value under section 53-19-37. There was no agreement, so there was no valuation formula, no discount for lack of marketability and no instalment schedule. The demand landed as a claim for roughly $520,000 in cash from a company whose assets were trees. A payment schedule clause would have turned that into a five-year note.

Example 3: An Albuquerque staffing firm that could not admit its investor

Three members ran an IT staffing business and agreed to sell fifteen percent to an outside investor for $400,000. Two members signed the term sheet. The third declined. Section 53-19-33 permits an assignee to become a member only with the unanimous consent of the other members, so the investor could have bought an economic interest with no vote and no information rights, which was not the deal. The round collapsed. A consent threshold of two thirds, written at formation, would have closed it.

The Financial Consequence of Silence, in Figures

New Mexico imposes no penalty for having no operating agreement, because it imposes no requirement. The cost shows up somewhere else.

The withdrawal exposure. The statutory put is the largest number on this page. A twenty percent member of a company worth $2.6 million can demand roughly $520,000 on thirty days notice, in cash, with no discount, unless the agreement says otherwise. On a company worth $900,000 a one third member can demand about $300,000. There is no ceiling; the ceiling is your valuation.

The allocation drift. Where a company distributes $150,000 a year among three members who each believe they are equal partners, but whose recorded contributions were $200,000, $50,000 and $0, the contribution-weighted default in section 53-19-22 sends $120,000 to one member and $30,000 to another, and nothing to the third. That is $50,000 a year moved by a rule nobody chose.

The financing that stalls. Because New Mexico publishes no ownership data, a bank, a factor or an SBA lender cannot verify beneficial ownership from the public record. Without an operating agreement and a member schedule the account is not opened and the facility is not drawn, and a company that cannot bank cannot collect. The cost is not a fee; it is the working capital that never arrives.

The dispute. A contested fair value proceeding needs a valuation expert on each side, document discovery and a hearing. Six-figure combined legal and expert costs are routine, and every dollar of it is spent settling terms that a written agreement fixes in advance for a flat fee. Reinstating a company that lapsed during a fight is a separate cost, covered on the New Mexico reinstatement page.

How File.Business Drafts a New Mexico Operating Agreement

The intake is built around the four provisions that actually decide outcomes here: contribution values, because they drive both votes and profits; the withdrawal right in section 53-19-37 and whether the members want it disabled or defined; the unanimity requirement on admitting members and whether it should be relaxed; and the management election, which has to be reflected in the articles as well as the agreement.

Delivery includes a member and contribution schedule formatted for a bank's beneficial ownership file, a signature page for each member, and a written consent adopting the agreement. Because New Mexico requires the company to keep prior versions under section 53-19-19, every amendment is dated and retained rather than replaced. The flat fee is $99 and no state fee attaches, because there is no filing. Where the company also needs a trade name, registering a New Mexico DBA is handled alongside it, and the recurring calendar is on the New Mexico annual report page.

When a template will do

A single-member company with no outside capital, no service contributions to value and no plan to admit anyone can run on a careful template, provided it is written to New Mexico rather than adapted from a per-capita state. Anything with two or more members earns a drafted document, and the trigger is easy to test. Open the template and look for a clause about withdrawal. If it does not disable or define the right in section 53-19-37, the template has left the largest liability in the statute switched on.

New Mexico Operating Agreement FAQ

Is an operating agreement required for a New Mexico LLC?

No. No provision of the New Mexico Limited Liability Company Act, NMSA 1978 sections 53-19-1 to 53-19-74, directs members to adopt one. The act supplies default rules instead, and those defaults govern completely wherever the members have not written something different.

Can a New Mexico operating agreement be oral?

No, and this is where New Mexico differs from most states. Section 53-19-2 defines an operating agreement as a written agreement providing for the conduct of the business and affairs of the company, together with that agreement as amended in writing. A verbal understanding is not an operating agreement and does not displace any statutory default.

Do I file the operating agreement with New Mexico, and what is the fee?

You do not file it. New Mexico has no form for it, no place to submit it and no fee, because it is a private contract kept at the company's principal place of business under section 53-19-19. The state fee you do pay is $50 to form the company, and New Mexico imposes no annual report on a limited liability company.

How does New Mexico divide profits when the agreement says nothing?

In proportion to contributions. Section 53-19-22 allocates profits and losses in the manner the articles or an operating agreement provide, and where neither provides for it, in proportion to the value of each member's respective contributions to capital. A member who contributed only unvalued labour receives nothing under that formula.

Can a member of a New Mexico LLC quit and demand to be paid?

Yes, unless the articles or the operating agreement say otherwise. Section 53-19-37 lets a member of a company with perpetual existence withdraw on thirty days written notice and entitles that member to receive the fair market value of the interest within a reasonable time. Disabling or defining this right is the most valuable clause a New Mexico agreement can contain.

Does New Mexico protect a membership interest from a member's creditors?

Partially. Section 53-19-35 lets a court charge a member's interest with payment of a judgment, and the creditor then has no more rights than an assignee. The section does not declare the charging order an exclusive remedy and does not address foreclosure, so New Mexico offers less certainty than states whose acts expressly bar both.

Can a New Mexico LLC create series with separate liability?

No. Article 19 contains no series provision, so a New Mexico company cannot partition assets into series with separate liability shields. Owners who need that separation use parallel companies, each with its own articles, its own operating agreement and its own books.
