Two founders start a company with 50% each. Four years later one of them runs it full time. The other stopped working in the business two years ago and still owns half of it. An investor is ready to commit, then reads the shareholder agreement. It says nothing about what happens when a founder leaves, and nothing about what happens when the two owners cannot agree.
The investor does not walk away. He makes the deal conditional on the founders settling it first. The buy-out is now negotiated in a week, under pressure, by two people who have not agreed on anything in a year.
That is what weak shareholder agreement clauses cost. Owners sign the agreement when they trust each other. The clauses only matter on the day they stop. Investors read every clause with that day in mind.
Why most shareholder agreements fail the investor's test
Most small-company agreements are written at the start, from a template, by people who expect to agree forever. They cover how much each person owns and little else.
The gaps are predictable. No rule for a founder who leaves. No way to break a 50/50 deadlock. No order for selling shares. No list of decisions that need every owner's consent. Each gap is harmless while relationships are good. Each one becomes a negotiation the moment money or a new shareholder arrives.
An investor who finds these gaps has two choices: wait while the owners fix them, or rewrite the agreement on his own terms. Neither is good for the founders.
The shareholder agreement clauses that matter most
A full agreement has many sections. These are the ones investors test first, because these are the ones that decide disputes.
Leaver provisions. What happens to a founder's shares if they stop working in the business. A "good leaver" (illness, agreed departure) usually keeps more value than a "bad leaver" (breach, walking away early). Founder shares that vest over time make this automatic.
Deadlock resolution. The steps when equal owners cannot agree: escalation, then mediation, then a mechanism that forces an outcome, such as one owner buying the other out at a set process.
Drag-along and tag-along. Drag-along lets a large majority require the minority to join a sale of the whole company. Tag-along lets a minority sell on the same terms if the majority sells. One protects the deal, the other protects the small shareholder.
Pre-emption and transfer rules. Existing owners get the first right to buy new shares or shares an owner wants to sell, before any outsider. This keeps strangers off the register.
Reserved matters. The decisions that need the consent of all owners, or a set majority: new shares, borrowing above a limit, selling a major asset, changing the business. Without this list, the majority decides everything.
Information rights. What every shareholder is entitled to see, and how often. Disputes start where information stops.
The uncomfortable part: the dangerous clause is the one you left out
Founders worry about the terms an investor will ask for. The bigger risk is the agreement between the founders themselves, and what it never said.
A missing leaver clause is not neutral. It means a departed founder keeps full ownership and full rights, and every future investor pays for that. A missing deadlock clause means a 50/50 company has no way to make a hard decision except by goodwill, which is usually what has run out.
The time to write these clauses is when nobody needs them. Agreeing the rules for a breakup while everyone is still friendly costs a few uncomfortable conversations. Agreeing them in the middle of one costs the deal.
How to prepare the agreement before you raise
Start by reading your current agreement against the list above and marking every gap. Then check it against the company's own records. In the UAE, a mainland company's memorandum of association is the document the authorities recognise, and a shareholder agreement that contradicts it can be hard to enforce. The two must say the same thing.
Check it against the share register too. If the agreement, the register and the promises made to early staff tell different stories, fix that first. A cap table clean-up before you raise covers exactly this, and the agreement is part of it.
Then have a lawyer draft the changes. This article is not legal advice, and these clauses need precise drafting. What owners must do themselves is decide the substance: who leaves on what terms, how a deadlock ends, who must agree to what. That is a governance decision, not a legal one. Owner alignment in writing is one of the deal-readiness steps in Investment Readiness for Growing Companies, because investors test it before they test the numbers.
Ask each owner one question, separately: if you left tomorrow, what would happen to your shares? If the answers differ, your agreement already has its first amendment.
