Yes. A business partner may be able to make certain decisions without your approval—even if you both own the company.
Whether they have that authority depends on how the LLC is managed, how voting rights are allocated, what authority has been delegated, and what the operating agreement requires for that particular decision.
Ownership does not automatically give every member a veto over every company action.
The question is not simply whether your partner acted without you. It is whether they had authority to do it.
Ownership Does Not Always Equal Control
Business owners often assume their ownership percentage controls every decision.
A 40% owner expects to control 40% of the vote. A 50% owner expects every decision to require their approval. A minority owner may assume that being listed as a member guarantees participation in management.
Those assumptions are not always correct.
An LLC can separate:
- Economic ownership
- Voting rights
- Management authority
- Officer responsibilities
- Contract-signing authority
- Approval rights over major decisions
A member may own a substantial part of the company without managing daily operations. A manager may control the business without owning any of it. An officer may have authority to sign certain contracts without asking every member first.
The operating agreement connects those roles—or separates them.
Is the LLC Member-Managed or Manager-Managed?
The first issue is how the LLC is governed.
Under Section 101.251 of the Texas Business Organizations Code, the governing authority of a Texas LLC may consist of its members or one or more managers.
In a member-managed LLC, the members collectively direct the business. That does not necessarily mean every member must approve every action. The operating agreement may establish voting thresholds or delegate defined responsibilities to particular people.
In a manager-managed LLC, the designated manager or managers direct the company’s affairs. A member who is not also a manager may have limited authority over daily operations.
That member still owns an interest in the company. But ownership alone may not allow them to override the manager or participate in every decision.
Your Ownership Percentage May Not Equal Your Voting Power
Texas’s default rules do not always allocate votes according to ownership percentages.
Under the statutory default, members and managers generally have equal votes. The operating agreement can modify that structure and allocate voting power based on ownership, class, position, or another agreed formula.
Consider an LLC with three members:
- One member owns 80%
- Two members each own 10%
- The operating agreement does not clearly tie voting to ownership
The 80% economic owner may not automatically hold 80% of every vote.
The opposite can also occur. An operating agreement may give a majority owner enough voting power to approve many decisions without the minority members.
The ownership schedule tells you who owns the economics.
The voting provisions tell you who controls the decision.
Ordinary Decisions Do Not Usually Require Every Owner’s Approval
A company could not function if every purchase, customer agreement, or employee decision required unanimous consent.
Ordinary business decisions are therefore often entrusted to managers, officers, or employees with delegated authority.
Depending on the company, an authorized person may be able to:
- Purchase inventory
- Hire ordinary employees
- Enter routine customer contracts
- Pay vendors
- Approve marketing expenses
- Set prices
- Engage service providers
- Manage existing projects
The operating agreement, company resolutions, employment roles, budgets, and past practices can all affect the scope of that authority.
Disagreeing with the decision does not necessarily make it unauthorized.
Your partner may make a poor business decision while still acting within the power the company gave them.
Major Decisions May Require Additional Approval
The analysis changes when an action falls outside ordinary business or fundamentally changes the company.
Those decisions may include:
- Admitting a new member
- Issuing additional ownership
- Taking on substantial debt
- Selling major company assets
- Entering a merger or conversion
- Amending the operating agreement
- Changing the certificate of formation
- Approving a related-party transaction
- Selling the company
- Winding up the business
Section 101.356 of the Texas Business Organizations Code establishes default approval requirements for certain company actions. The operating agreement may also identify reserved matters requiring a majority, supermajority, or unanimous vote.
The substance of the transaction matters.
A partner cannot necessarily avoid an approval requirement by labeling an extraordinary transaction “ordinary business.”
Can Your Partner Sign a Contract Without You?
Possibly.
A governing person or officer with actual or apparent authority may act as an agent of the LLC. Under Section 101.254 of the Texas Business Organizations Code, an authorized person’s actions in the apparent ordinary course of business can bind the company unless that person lacked actual authority and the third party knew about the limitation.
That creates two different questions:
- Did your partner violate an internal restriction?
- Is the LLC still bound to the third party?
The answers may be different.
Suppose one member signs a vendor agreement exceeding an internal spending limit. The company may still face an enforceable contract if the vendor reasonably believed the member had authority and did not know about the restriction.
The other members may have an internal claim against the person who exceeded their authority. That does not automatically erase the company’s external obligation.
Private limitations are most effective when the company documents, follows, and communicates them consistently.
Can Your Partner Act Without Holding a Meeting?
In some circumstances, yes.
Texas law permits certain LLC actions through written consent without a traditional meeting. Under Section 101.358, an action may be approved when written consents are signed by the number of authorized voters required to take it.
The operating agreement may establish different or additional procedures.
Written consent does not reduce the required number of votes. If the operating agreement requires unanimous approval, one member cannot avoid that requirement by signing a resolution alone.
But if a majority is sufficient and your partner controls that majority, your signature may not be required.
The approval threshold matters more than the format of the decision.
What If You Own 50%?
If you and your partner have equal voting power, neither of you may be able to approve a matter requiring a majority without the other.
That does not mean neither person can make any decision.
Each owner may still have delegated authority over ordinary operations. Existing officers and employees can continue performing their responsibilities.
Deadlock occurs when a decision requiring member approval cannot receive enough votes.
A 50% owner cannot create a majority alone. But the extent of the stalemate depends on which decisions require a vote and which have already been delegated.

What If the Decision Was Unauthorized?
Start by identifying:
- What action was taken
- Who took it
- What role that person held
- Whether the LLC is member-managed or manager-managed
- What the operating agreement authorizes
- What approval threshold applied
- Whether authority had been delegated
- Whether a third party knew about any limitation
- Whether the transaction can still be stopped
Timing matters.
Before a transaction closes, the company may be able to revoke authority, notify the other party, formally reject the action, or seek an injunction.
After performance begins, the company may already be bound even if the individual violated an internal restriction.
Stopping the transaction and allocating responsibility are different problems.
Authority Should Be Designed, Not Assumed
Your business partner may be able to make decisions without you.
That authority may come from the operating agreement, management structure, an officer position, a company resolution, or established practice.
But authority has boundaries.
Owning more of the company does not automatically create unlimited power. Owning half does not automatically create a veto over every operational decision.
The answer comes from tracing the decision through the company’s structure:
Who had authority? What approval was required? Was the process followed?
When those questions are answered in advance, the company can move without turning every decision into an ownership dispute.
