Member-managed vs. manager-managed LLC: who can sign, who can bind, who decides

The default, stated by the statute

Unless the operating agreement says otherwise, an LLC is managed by its members. Delaware states the rule in section 18-402 of its LLC Act: management is vested in the members in proportion to their percentage interests in profits, and decisions are made by the members holding more than 50 percent of those interests, unless the agreement provides otherwise. Read that twice, because it quietly sets three defaults at once. Authority follows profit share, not headcount and not effort. A member holding 60 percent of the profits controls ordinary decisions alone. And every member, by default, is part of management, which means every member's acts are management acts.

The same section carries the authority rule that makes the choice matter outside the company: unless the agreement provides otherwise, each member and each manager is an agent of the company for the purpose of its business, and an act of a member or manager for apparently carrying on the company's business in the usual way binds the company, unless the person they dealt with knew the actor had no authority. Other states write their defaults differently, and several ask for the management structure on the formation filing itself, but the pattern is the same everywhere: the state supplies a default management answer, and the agreement is where the company replaces it with its own.

What member-managed actually means day to day

In a member-managed company, the owners are the management. Any member can run operations, hire, spend within whatever limits the agreement sets, and sign for the company. For a two or three owner company where every owner works in the business, this is the honest structure: it matches how the company already runs, keeps decisions at the speed of conversation, and avoids the oddity of owners appointing themselves managers and then acting in two capacities on the same afternoon.

Its costs appear with scale and with money. Every additional member is another person who can bind the company, which lenders, landlords, and counterparties all notice. A member who contributes capital but not work still holds management rights by default, including a vote weighted by profit share, and removing a disruptive member from management means amending the agreement or worse. Member-managed is a small-room structure. It works while the room is small and the people in it trust each other's signatures.

What manager-managed actually changes

A manager-managed company vests management in one or more managers, named or elected under the operating agreement. Managers may be members, or may be people who own nothing at all: a hired operator, a professional manager, a spouse running the business the investors funded. The members keep their economic rights and whatever big-decision votes the agreement reserves to them, and they choose, and can replace, the managers. The members who are not managers step out of daily authority, and, critically, out of the default agency: a non-manager member signing a contract in the company's name is no longer obviously someone who can bind it.

The structure earns its keep in four situations. Outside or passive investors who want their money managed, not voting on vendors. A professional operator who needs clean authority to run the company. A larger or growing membership where universal signing power is a risk rather than a convenience. And family or estate arrangements where ownership is spread wider than the group who should run the business. Its costs are real: a layer of governance to maintain, manager duties to define, and a company outsiders will read more carefully, because the person across the table may need to check that the signer really is the manager.

Who can bind the company: the comparison that matters most

Strip both structures down to the counterparty's question: if this person signs, is the company bound? In a member-managed company, effectively every member. In a manager-managed company, the managers, and the agreement can still scope that authority, for example by requiring member approval above a stated amount. Delaware's statutory sentence adds the nuance that protects outsiders: an act binds the company when it appears to be in the usual course of business, unless the counterparty knew the signer lacked authority. In plain terms, internal limits protect the company best when outsiders have actually been told about them. A limit that exists only in a drawer is a limit the company may lose with.

That is why banks and lenders ask for the operating agreement and for resolutions naming who may borrow and sign. They are not being ceremonial. They are establishing, for their own protection, exactly which humans carry the company's signature under its chosen structure, and manager-managed companies give them a shorter list to establish.

• Member-managed: every member can ordinarily bind the company.
• Manager-managed: managers bind it; non-manager members ordinarily do not.
• Internal spending limits bind outsiders mainly when outsiders know about them.
• Banks will ask for the agreement and a signing resolution under either structure.

Decision rights: ordinary business versus the big list

Under Delaware's default, ordinary decisions follow profit-weighted majority. A well-drafted agreement in either structure replaces that blunt rule with two lists: what management may do alone, and what needs member approval. The second list is where owners actually protect themselves, and it looks similar in both structures. Sale of the company or substantially all its assets. Admission of a new member. Borrowing above a set amount. Amending the agreement. Dissolving. A manager-managed company that reserves none of these to the members has handed the company to its managers in substance. A member-managed company whose agreement sets no thresholds has made every grocery run a potential argument about authority.

The choice between structures is therefore narrower than it first looks. Both need the big list. The structures differ on the ordinary list: in one, every owner holds daily authority; in the other, named managers do, and owners supervise through the appointment, the budget, and the reserved decisions.

Taxes and roles: what the choice does not change

Management structure is not a tax classification. A member-managed and a manager-managed LLC with the same members are taxed the same way by default, as a partnership, and either can make the same elections. Where the choice touches money personally is self-employment tax treatment and guaranteed payments, and there the working member's role matters more than the label: a member who works in the business is treated differently from a purely passive investor, and the manager question interacts with that line in ways worth an hour with a tax adviser before the agreement is signed, not after the first return surprises everyone.

Also separate: manager is a role, not an ownership interest. A manager who owns nothing has authority without economics. A member who manages has both. Pay, duties, and removal for a non-member manager belong in a written management arrangement, and the operating agreement should say whether a manager who is also a member loses the role, the membership, or both, on exit.

Making and changing the choice

Some states ask the question at formation and record the answer on the public record; others leave it entirely to the agreement. Delaware is in the second group: the filed certificate of formation does not state the structure, so the operating agreement is the whole record, and changing structures is an agreement amendment, done under the amendment procedure the agreement itself sets. The amend guide on this site covers that machinery, including the prompt-amendment duty when a filed statement has become false. Where a state does record the structure publicly, changing it is also a state filing, and the counterparty-facing record and the agreement must be moved together, in the same week, so the two never tell different stories to a bank.

Changing from member to manager management mid-life is common and usually signals growth: the first passive investor arrives, or the owners hire an operator. Plan it as a governance event, not a form. New agreement language, new signing resolutions, notice to the bank and the major counterparties, and updated records everywhere the old authority was described.

Worked example: the same three owners, two structures

Three owners form a company. Owner A works full time in it. Owners B and C contributed most of the money and work elsewhere. Profit shares are A 20 percent, B 40 percent, C 40 percent. Member-managed under the Delaware default, management follows profit share: B and C together hold 80 percent of the vote on ordinary decisions, and each of them, plus A, can bind the company by signing. The person doing the daily work holds the smallest vote and shares signing power with two people who are rarely on site. Nothing about that is illegal, and everything about it predicts friction: A needs B or C for contested decisions, and B's signature on a supplier contract at a trade show binds the company whether A likes the terms or not.

The same company, manager-managed, names A as manager with authority for operations up to a stated amount, reserves borrowing above that amount, new members, and any sale to a member vote, and leaves B and C with economics, information rights, and the power to replace the manager. Now the daily authority sits with the person doing the work, the money's protection sits in the reserved list and the replacement power, and a counterparty checking the record sees one signer. The owners' percentages never changed. What changed is that authority was assigned on purpose instead of inherited from a formula.

Mistakes that recur

The first is copying a structure from a template or a friend's company without mapping it to who works, who paid, and who should sign. The second is choosing manager-managed and then letting every member keep signing as before, which gives the company the paperwork of one structure and the exposure of the other. The third is a manager-managed agreement with no reserved decisions and no removal procedure, which is not a structure but an abdication. The fourth is the opposite corner in a member-managed company: no thresholds at all, so a member acting alone commits the company to its largest contract. The fifth is forgetting that the public record, the agreement, the bank's file, and the agent's records are four copies of the same answer, and letting them drift apart.

Checklist

1. Write down who works in the business, who funded it, and who should be able to sign.
2. Read your state's default rule before assuming the agreement is the whole answer.
3. If members manage: set spending and borrowing thresholds in the agreement anyway.
4. If managers manage: name them, set their authority limits, and reserve the big decisions to members.
5. Write the manager removal and replacement procedure before anyone needs it.
6. Decide how a manager who is also a member exits each role.
7. Give the bank the agreement and a signing resolution; update both when the structure changes.
8. If your state records the structure publicly, change the filing and the agreement together.
9. Ask a tax adviser how working and passive roles interact before signing.
10. Re-check the choice at every investor, operator hire, or ownership change.

Next step

Use the linked tools and state records before you rely on a general rule. LLC duties turn on the state, the owners, the activity, and the tax choice.
