What Your Shareholder Agreement Must Cover Before Things Go Wrong
You started the agency with a mate. You trust each other. The handshake felt like enough, and for the first few years it was. Then one of you wants to buy a rent roll and gear up, the other wants to slow down and take money out of the business. Suddenly the two of you want very different things from the same business, and there is nothing on paper that says how to sort it out.
This is the moment most business partners wish they had a shareholder agreement. Not when everything is going well, but when it is not. By then the conversation is harder, the stakes are higher, and the goodwill that once smoothed everything over is running thin.
A shareholder agreement is the document that answers the hard questions before they become fights. It is not a sign that you distrust your partner. It is the opposite. It is proof that you both care enough about the business, and the relationship, to protect them properly. Here is what it is, what it should cover, and why going without one is a risk you do not need to take.
What a Shareholder Agreement Actually is
A shareholder agreement is a private contract between the owners of a company. It sets out how the business is run, how decisions get made, what each owner is entitled to, and what happens when someone wants out or when the owners disagree. It sits alongside the company constitution, but it goes much further and stays private between the parties.
Think of it as the rule book for your partnership. When everyone agrees, you barely look at it. When you do not, it is the thing that keeps the business moving instead of grinding to a halt. A good agreement is written for the bad day, not the good one, and that is exactly why it is worth doing while everyone is still getting along.
Many owners assume the law already covers this. It does, up to a point. Company law provides a set of default or replaceable rules. The problem is those defaults are generic. They were not written for your business, your goals, or the way you and your partners actually work. Relying on them is like buying an off the plan apartment and never checking the floor plan. You get something, but almost never what you would have chosen.
There is another myth worth clearing up. A shareholder agreement is not the same as your company constitution, and one does not replace the other. The constitution is a formal document that sets the basic legal framework of the company. The shareholder agreement is private, commercial, and specific. It deals with the real questions owners care about, like how shares are valued and who is allowed to buy them, that a constitution simply does not touch. Most well run companies have both, drafted to work together rather than contradict each other.
Why a Handshake is Not Enough
Partnerships rarely fall apart over the thing you expect. They fall apart over the thing nobody discussed. Two owners with equal shares and no agreement is a classic setup for deadlock. If you each hold half the company and you cannot agree, who breaks the tie? Without an agreement, the honest answer is nobody (or the courts), and a business that cannot make a decision is a business in trouble.
Case Study
The Fifty-Fifty Split With No Exit Plan
Two agents we will call Sam and Tom built a rent roll together on a fifty fifty split. No agreement, just trust. Five years in, Sam wanted to sell his half and move interstate. Tom did not want a stranger as a business partner, but he had no right to buy Sam out first, no agreed way to value the shares, and no process to follow. What should have been a clean exit became months of tension, legal cost, and a friendship that did not survive it. A shareholder agreement would have set the price method and the process on day one.
The same gap shows up in dozens of ways. What if one partner stops pulling their weight? What if someone wants to bring in a new investor? What if an owner divorces, becomes ill, or dies, and their shares pass to a spouse who has never worked a day in the business? Without an agreement, you are left negotiating each of these under pressure, often with someone whose interests no longer match yours.
It is worth being honest about why these conversations get skipped. Talking about exit, death, or disputes feels like planning for failure, and no one wants to sour the excitement of a new venture. But avoiding the conversation does not remove the risk. It just delays it to the worst possible moment, when emotions are high and positions have hardened. The paperwork you resist at the start is the paperwork that saves the relationship later.
What a Shareholder Agreement Should Cover
Every agreement is tailored to the business, but the strong ones deal with the same core areas. Skipping any of them is where the risk creeps back in.
Ownership and contributions. Who owns what percentage, what each person put in, and how future capital calls are handled if the business needs more money. This sets the baseline for everything else.
Decision making. Which decisions the owners can make day to day, and which ones need everyone to agree. Big moves like taking on debt, buying a rent roll, selling the business, or hiring at a senior level usually sit in the second bucket. Clear thresholds stop one owner from committing the others to something they never signed up for.
Roles and commitment. Who does what, how much time each owner is expected to put in, and what happens if someone stops contributing. In an agency where one owner lists and sells while the other runs operations, spelling this out early prevents the slow resentment that builds when one partner feels they are carrying the other.
Money out. How profits are shared, when dividends are paid, and how any owner who also works in the business is paid for that work. Confusing your return as an owner with your pay as an operator is a common and avoidable source of conflict, and it is one of the first things we untangle when partners come to us mid dispute.
Funding the business. If the agency needs more capital to buy a rent roll or ride out a slow quarter, the agreement should say how that money is raised, whether owners must chip in proportionally, and what happens to someone who cannot or will not. Money questions answered in advance are money questions that never become arguments.
Selling and exit. What happens when someone wants to leave. Pre-emptive rights give the other owners first option to buy before shares can go to an outsider. Drag along and tag along rights protect everyone if a full sale comes up, so a majority cannot force a raw deal on a minority, and a minority cannot block a good sale for everyone else.
Valuation.The single clause partners fight over most is how the shares are priced. Agreeing the valuation method up front, while nobody knows who will be buying and who will be selling, takes the heat out of the hardest conversation you will ever have.
The unexpected.Death, permanent illness, or incapacity of an owner. A good agreement says what happens to those shares, and often pairs with insurance so the remaining owners can afford to buy them without draining the business.
Dispute resolution and restraint. A clear path for breaking a deadlock and sensible restraints so an exiting owner cannot walk out the door and set up in direct competition next week using the relationships the business paid to build.
The Clause Agency Owners Forget Until It Hurts
For real estate agencies, one issue deserves special attention. Your rent roll and your client relationships are the value of the business. If a shareholder exits, what stops them from taking clients, staff, or the rent roll with them? A well drafted restraint and a clear treatment of the rent roll on exit can be the difference between selling your share of a valuable asset and watching that asset walk out the door.
Case Study
The Silent Clause That Sparked a Fight
An agency with three owners had a solid looking agreement, but it never dealt with what happened to managements if an owner left. When one departed, he argued the landlords he had personally signed were his to take. The remaining owners disagreed. The agreement was silent, so the fight went on far longer and cost far more than the clause would have taken to write. Detail is not bureaucracy. Detail is what protects the value you have built.
It Costs Less Than the Argument it Prevents
Owners often hesitate at the cost of getting an agreement drafted properly. It is a fair question, but it is the wrong comparison. The real comparison is not the agreement versus nothing. It is the agreement versus the dispute it is designed to prevent. A well drafted shareholder agreement is a modest, one off investment. A partnership fight without one can run for months or even years, drain the business of cash and focus, and in the worst cases force a fire sale of the very asset you built together.
We have seen both sides of this. The owners who invest early treat the agreement as insurance they hope never to use, and most never do. The owners who skip it almost always pay more later, in legal fees, lost time, and damaged relationships. Proactive legal strategy is not an expense. It is the cheapest protection money can buy for the thing you have worked hardest to build.
When To Put One in Place
The best time to sign a shareholder agreement is at the start, when everyone is optimistic and interests are aligned. The second best time is now. If you are already in business with partners and you do not have one, you are not too late, but every month without one is a month of exposure.
It matters even more when the business is about to change shape. Bringing in a new owner, buying a rent roll, structuring to scale or thinking about a future sale are all trigger points. An agreement written before the change is calm and commercial. One negotiated during the change is tense and expensive. Getting ahead of it is simply smart structuring, and it lets you expand with confidence instead of exposure.
This is where the right legal partner earns their place. A commercial lawyer who understands agencies will not just hand you a template. They will ask the questions you have been avoiding, map the what ifs to your actual business, and turn a difficult conversation into a clear, signed plan that protects every owner and the business itself.
What Putting One in Place Actually Looks Like
The process is more straightforward than most owners fear, and the value is as much in the conversation as the document. A good commercial lawyer starts by asking the questions you have quietly avoided. What happens if one of you wants out in five years? What if someone gets sick? What if a great offer comes in for the whole business but only one of you wants to sell? Your answers become the agreement.
From there, the terms are drafted, reviewed, and refined until every owner understands and accepts them. That understanding matters as much as the signatures, because an agreement nobody read is almost as risky as no agreement at all. Done properly, the result is a document that sits quietly in the drawer, giving each owner the confidence that the hard questions already have answers. That is what it means to build a business that is positioned to grow and protected along the way.
Key Takeaways
A shareholder agreement is a private contract between company owners that sets out how the business is run and what happens when owners disagree or want out.
Company law only gives you generic default rules. They were not written for your business, your goals, or your partners.
Two equal owners with no agreement is a recipe for deadlock. A business that cannot decide is a business in trouble.
A strong agreement covers ownership, decision making, profit sharing, exit and pre-emptive rights, valuation method, death and incapacity, and dispute resolution.
For agencies, deal specifically with the rent roll, client relationships, and restraints so value cannot simply walk out the door.
The best time to sign one is at the start. The second best time is now, especially before you buy, scale, or take on a new owner.

-
Yes. A constitution sets the basic framework, but it does not deal with the private commercial arrangements between owners, such as how shares are valued, who can buy them, and how disputes are resolved. A shareholder agreement fills those gaps and stays private between the parties.
-
Without one, you fall back on generic company law defaults that were not designed for your business. Common problems include deadlocks between equal owners, no agreed way to value or sell shares, and no protection if an owner leaves, becomes ill, dies, or wants to bring in an outsider.
-
Ideally at the start, when owners are aligned and optimistic. If you are already in business without one, the next best time is now. It is especially important before bringing in a new owner, buying a rent roll, scaling the business, or planning a future sale.
