The question nobody wants to answer honestly I have watched people spend £40,000 chasing £25,000. They knew the maths did not work. They did it anyway because they were angry, or because they felt wronged, or because backing down felt like losing. Sometimes it is worth fighting. Sometimes the principle matters more than the money. But you need to make that decision with your eyes open, not in the heat of the moment. This is not legal advice. I am not a solicitor. What I am is someone who has sat with business owners working through this exact question, helping them think clearly when everything feels urgent and personal. The real cost is not the legal fees Legal fees are the obvious cost. But they are rarely the biggest one. The real cost is distraction. A dispute takes your attention away from the thing that actually makes you money. Every email chain, every call with your solicitor, every hour spent digging through old contracts is an hour you are not spending on clients, on growth, on the work that matters. I worked with someone last year who pursued a supplier dispute for 14 months. They won. They recovered about £18,000. But during those 14 months, they estimated they lost at least £50,000 in missed opportunities because their head was not in the business. The stress affected their decision-making. They passed on a partnership that, in hindsight, would have been worth far more than the settlement. Before you decide to fight, ask yourself: what will this cost me in focus? When the numbers actually work Sometimes the numbers do work. Here is when I think pursuing a dispute makes sense: The amount at stake is significant relative to your business. If someone owes you £80,000 and your annual revenue is £200,000, you cannot afford to let that go. The maths is different if someone owes you £3,000. You have clear documentation. Contracts, emails, invoices, delivery records. If you have to reconstruct the story from memory, you are already on shaky ground. The other party has assets or income. Winning a judgment against someone who cannot pay is an expensive piece of paper. I have seen people win cases against companies that then dissolved. There was a story recently about a film producer whose 50 companies were struck off, leaving suppliers with no entity to claim against. This happens more often than you would think. Your solicitor gives you better than 70% odds. Anything below that and you are gambling. Even at 70%, you need to be prepared to lose. When to walk away Walking away feels like defeat. It is not. It is a business decision. Consider walking away when the dispute is primarily emotional. If your main driver is that you feel disrespected, or that the other party behaved badly, or that you want to teach them a lesson, pause. Those are valid feelings. They are not good reasons to spend £15,000 on solicitors. Consider walking away when the timeline is uncertain. Litigation can take two years. Sometimes longer. Can your business absorb that uncertainty? Can you? Consider walking away when settlement is possible. Most disputes settle before trial. If there is a realistic settlement number that you can live with, explore it early. A quick settlement at 60% of what you are owed is often better than a full judgment in 18 months. A framework for the decision When I help people work through this at ALIRA., we usually run through a simple decision matrix. Not because it gives you the answer, but because it forces you to weigh factors you might otherwise ignore. The factors I typically include: amount at stake, strength of evidence, likelihood of recovery, estimated legal costs, estimated time to resolution, impact on business focus, and emotional weight. You score each one. You weight them based on what matters most to you. The Decision Matrix tool on alira.london can help structure this if you want something more formal than a spreadsheet. But here is the thing: even after running the numbers, sometimes the answer is still unclear. That is when you have to trust your gut about whether you can sustain the fight. The 72-hour rule I tell everyone the same thing: do not make this decision in the first 72 hours after something goes wrong. When you first discover you have been wronged, you are angry. You want justice. You want the other party to suffer consequences. These are normal reactions. They are also terrible foundations for a multi-month legal process. Wait three days. Let the initial heat pass. Then look at the situation with clearer eyes. I have seen people draft furious legal letters at 11pm on a Friday. By Monday, they realised the dispute was not worth their time. The 72-hour pause saved them money and stress. What about reputation? Some disputes are about protecting your reputation. If someone is defaming you, or if a former employee is breaching a non-compete in a way that damages your market position, the calculus changes. But even then, ask yourself: will legal action actually fix the reputational harm? Or will it draw more attention to the problem? Sometimes the best response to reputational attacks is to outperform. To let your work speak louder than the noise. Legal action can feel like the strong move, but it can also signal that you are rattled. What to do this week If you are facing a potential dispute right now, here is what I would do: First, gather every piece of documentation you have. Contracts, emails, invoices, messages. Put them in one folder. Do not interpret them yet, just collect them. Second, write down the three outcomes you would accept. Not what you want ideally, but what you could genuinely live with. This clarifies your thinking before you speak to anyone else. Third, get one hour with a solicitor who specialises in this area. Not your mate who does conveyancing. Someone who handles commercial disputes regularly. Ask them for a realistic assessment of costs, timeline, and odds. If their answer is vague, find someone else.
