When Informal Business Agreements Create Serious Corporate Disputes

Closely held businesses almost always begin with trust, optimism, and a shared vision. Founders, family members, friends, and early investors start building the company long before they have fully documented who owns what, who controls the board, and how major decisions will be made.

That informality works—until it doesn’t. When disagreements inevitably arise, the absence of clear written agreements and corporate formalities turns an ordinary business dispute into a full-blown conflict over ownership, control, and the survival of the company itself.

At Tajima LLP, we frequently litigate these exact scenarios. We see what happens when founders are squeezed out by minority shareholders who quietly accumulated voting power, or when a CEO is abruptly ousted from the company they built because the bylaws were never properly formalized. What could have been a straightforward negotiation instead becomes a complex battle over corporate control.

The Trap of the “50/50” Handshake

Many small businesses are formed around a simple premise: two people will own and run the business equally. A 50/50 arrangement sounds fair on day one, but it is often a recipe for deadlock.

Without a clear operating agreement or shareholder agreement, a 50/50 structure fails to answer critical questions:

When owners become deadlocked, the business paralyzes. Employees receive conflicting directives, vendors go unpaid, and the owners are often forced into expensive litigation or a distressed buyout that could have been avoided with a basic tie-breaking mechanism in their corporate documents.

Operating Owners vs. Capital Investors

Another frequent source of conflict occurs when one owner actively operates the business while another serves primarily as a silent investor. Initially, this division of labor seems practical. Problems arise when expectations diverge and documentation is sparse.

The operating owner often believes they should have absolute control because they are doing the daily work. The non-operating investor believes their capital contribution gives them equal say in strategic decisions. This disconnect breeds disputes over executive compensation, access to company books and records, hiring decisions, and profit distributions.

These conflicts become particularly aggressive when the company’s governing documents fail to distinguish between ownership rights, management authority, and board voting rights. In closely held companies, these roles blur in practice, but legally, they are distinct. When a dispute erupts, those legal distinctions dictate who holds the power.

Why Corporate Formalities Actually Matter

Corporate formalities are frequently dismissed by early-stage founders as “paperwork” to be handled later. But when a dispute arises, proper documentation determines whether a corporate action was validly authorized or an illegal power grab.

In our practice, we regularly litigate cases where the absence of formal records becomes the central issue. When capitalization tables are incomplete, board consents are unsigned, or officer appointments are informal, fundamental questions become heavily contested:

In litigation, the absence of formal records is often just as weaponized as the records that do exist.

The Reality of Corporate Control Disputes

When business relationships break down, informal arrangements create a chaotic battlefield. At Tajima LLP, we represent clients navigating the fallout of these undocumented expectations.

We frequently handle disputes involving:

These disputes are highly disruptive. They threaten the company’s value, spook lenders, and damage customer relationships.
