Does Your Louisiana LLC Need an Operating Agreement?
By Bloom Legal Staff · Last reviewed: October 2026
Short answer: Louisiana does not require an operating agreement to form an LLC, but almost every LLC should have one in writing. Without it, state law fills in the rules for you, and those default rules often do not match what the owners actually agreed to.
You can form a Louisiana LLC online in an afternoon by filing articles of organization with the Secretary of State. The articles are public and short. The operating agreement is the private document that says how the business actually runs: who owns what, who gets paid, and what happens when someone wants out.
What Louisiana Law Says About Operating Agreements
The definition is in La. R.S. 12:1301(A)(16), and the distinction between single-member and multi-member LLCs matters:
- Multi-member LLC: an operating agreement can be any agreement among the members, written or oral.
- Single-member LLC: the operating agreement must be a written agreement between the member and the company.
Nothing in the statute forces you to sign one. But many of the default rules in Title 12 can only be changed by a written operating agreement. A handshake understanding between partners will not override them.
Bottom line: if it is not written down, Louisiana’s default rules decide who gets paid, how votes count, and what a departing owner is owed.
The Default Rules That Surprise Business Owners
These are the defaults that cause the most trouble when an LLC has no written agreement.
Profits and losses are split equally
Under R.S. 12:1323, profits and losses are allocated the way a written operating agreement says. If it says nothing, they are split equally among the members.
Suppose one partner puts in $90,000 and the other puts in $10,000. Without a written agreement, each is allocated half the profits, not the 90/10 split they had in mind.
Every member gets one vote
Under R.S. 12:1318(A), each member gets one vote and decisions are made by majority vote of the members, no matter who owns more. We covered this, along with who can sign leases and contracts, in The LLC You Formed Online: What to Fix Before You Sign a Lease or Add a Partner.
A member can walk away and be paid fair market value
Under R.S. 12:1325, if the LLC was not formed for a set term and the written agreement does not say otherwise, a member can withdraw on 30 days’ written notice to the company and to each member and manager. The company then owes that member the fair market value of their interest, measured on the date they leave, within a reasonable time.
For a small company, that can mean an unplanned cash payout at the worst possible moment. A written agreement can set a longer notice period, a valuation formula, or a payment schedule. It can also limit when withdrawal is allowed at all, so one owner’s decision to leave does not force the others to find cash or bring in a lender on short notice.
New owners need everyone’s consent
By default, someone who buys or inherits an interest gets the economic rights but does not become a voting member unless all the other members consent in writing (R.S. 12:1332). An operating agreement can change that, or set out in advance who can come in and how.
Why a Single-Member LLC Still Needs One
Solo owners often skip the operating agreement because there is no one to disagree with. There are still good reasons to sign one:
- Banks and lenders ask for it. Many banks ask to see an operating agreement before opening a business account or approving a loan. It shows who has authority to act for the company.
- It shows the company is separate from you. Courts look at whether owners treat the LLC as a separate business when deciding whether to hold them personally liable. A signed agreement does not guarantee protection on its own, but it supports the separation. See our post on piercing the corporate veil.
- It plans for incapacity and death. If you are the only member and you become incapacitated or die, someone has to be able to run the business, pay employees, and sign checks. The agreement can name that person and spell out the transition.
- It makes adding a partner easier. If you bring in an investor or partner later, you will be amending an agreement that already exists instead of negotiating from a blank page.
Default Rules vs. a Written Agreement
| Issue | Louisiana Default (No Written Agreement) | What a Written Agreement Can Do |
|---|---|---|
| Profit and loss split | Equal among members (R.S. 12:1323) | Split by ownership percentage or any agreed formula |
| Voting | One member, one vote; majority rules (R.S. 12:1318) | Votes weighted by ownership; supermajority for key decisions |
| Leaving the company | 30 days’ notice, fair market value payout (R.S. 12:1325) | Longer notice, valuation formula, payment over time |
| New owners | Unanimous written consent to become a member (R.S. 12:1332) | Pre-approved transfers or a lower approval threshold |
| Single-member LLC | Agreement must be written to count (R.S. 12:1301(A)(16)) | Names a successor and documents authority |
What to Put in Your Operating Agreement
A useful operating agreement does not have to be long, but it should answer these questions:
- Who owns what percentage, and what each owner contributed (cash, property, or services).
- How profits are split and when distributions are paid.
- How votes are counted and which decisions need unanimous approval.
- Who manages the business day to day and who can sign contracts, leases, and loans.
- What happens when an owner leaves, including notice, how the interest is valued, and how the buyout is paid.
- What happens on death, disability, or divorce, since Louisiana’s community property rules can affect who ends up with an interest. Our post on buy-sell agreements covers this in more detail.
- How disputes and deadlocks are resolved when members split evenly.
Review the agreement whenever ownership changes, the business takes on major debt, or an owner’s family situation changes.
Frequently Asked Questions
Is an operating agreement required in Louisiana?
No. You can form an LLC without one. But without a written agreement, Louisiana’s default rules control profits, voting, and buyouts.
Do I file my operating agreement with the Secretary of State?
No. The articles of organization are filed. The operating agreement is a private document kept by the company.
Does a single-member LLC need a written agreement?
For a single-member LLC, Louisiana law recognizes only a written operating agreement. It also helps with banks, lenders, and succession planning.
Can we use a free online template?
A template is better than nothing, but most are not written for Louisiana. They often miss the state’s default rules and community property issues.
Can we change the agreement later?
Yes. Under R.S. 12:1318(B)(6), amending an operating agreement takes a majority vote of the members unless the agreement sets a different process.
