Businesses weigh the cost of running a claim and rarely weigh the cost of running one that does not succeed. The two are different, and the second is the one that does lasting damage. Establishing which kind of claim you have is the point of an initial dispute review, and it is cheap relative to what it prevents.
This is not an argument against pursuing entitlement. Where the contract supports a position and the records prove it, pursuing it is ordinary commercial management. The argument is against pursuing a position that has not been tested, on the assumption that something will turn up.
What the other side learns about you
A claim that collapses tells the other side something they will remember. It tells them that your assessment of your own position was wrong by a significant margin, and that you were willing to commit to it anyway.
On a single project that costs you the remainder of the negotiation. Across a continuing relationship it costs more than that, because every future position you take is read against the one that failed.
The same works in reverse, which is why discipline is worth having. A party known for pursuing only what it can prove gets taken seriously when it raises something, and that reputation is worth real money over several projects.
The cost of the position you cannot retreat from
Claims that have been formally stated are hard to withdraw. The person who signed the letter has to explain the change, the board has to accept that money was spent for nothing, and the commercial team has to go back to the other side with less than they asked for.
The result is that weak claims tend to continue past the point where anybody believes in them, because continuing is easier than stopping. That is where the cost escalates, since each month adds fees and management time to a position that is not improving.
The best protection is to avoid stating a position that has not been tested. There is no obligation to put a figure in writing early, and doing so buys very little while committing a great deal.
Cash that is committed rather than recovered
A claim consumes working capital while it runs, both in fees and in the money that stays unpaid. For a contractor that is capital locked into a completed project; for a developer it can hold up the closing of a scheme.
Where the claim succeeds, that cost is recovered or at least justified. Where it fails, the cash has gone and the sum it was chasing has gone with it.
The exposure is largest for businesses whose working capital is already stretched, which is frequently the same businesses most tempted to run a speculative claim because they need the money.
That combination deserves naming, because it is where the worst outcomes happen. A business under cash pressure runs a claim it has not tested, spends money it does not have pursuing it, and ends up settling low because it can no longer afford to wait.
The relationship cost, where there is one
Not every dispute damages a relationship. Parties that know each other well frequently disagree formally and continue working together, because both sides understand that a contractual position is not a personal one.
What does damage a relationship is a claim the other side believes to be opportunistic. The distinction they draw is not between winning and losing; it is between a position that was arguable and one that was not.
That judgement is made early, on the basis of how the claim is put. A claim that identifies its own weaknesses is read very differently from one that asserts everything with equal confidence.
What makes a claim weak
Usually one of three things. No contractual route, so the complaint is about fairness rather than entitlement. A route that exists but was not followed, typically a notice that was late or never served. Or records that do not support what is being asserted.
The third is the most common and the most recoverable, because gaps in records can sometimes be closed while the project is still fresh. The first two are structural and are rarely improved by effort.
Knowing which one you have determines everything. A sound entitlement with thin records is worth working on. A missing entitlement is not, however good the records are.
This is also why the claims and dispute services are separate pieces of work rather than one. A payment dispute, a disputed account and a claim for time fail for different reasons, and the test that tells you whether yours is sound is different in each case.
The decision this is really about
Running a claim is a commercial commitment and deserves the scrutiny of any other commitment of the same size. The question is not whether you have been treated badly but whether the contract gives you a remedy and the documents prove the facts.
Answering that takes days rather than months and costs a fraction of the alternative. It is also the only point at which stopping is free, because nothing has been asserted to anybody outside the business.
Where the answer is that the position is sound, the work that follows is ordinary and well understood, whether that is a disputed account, a payment cycle or a claim for time. Where the answer is that it is not, the saving is everything that would have been spent finding out the hard way. The underlying prevention is commercial management during the works, which is what makes positions strong in the first place.
Not sure whether the claim is worth running?
An initial dispute review reads the contract and the correspondence, tests whether an entitlement exists and tells you what the dispute is likely to absorb before you commit to it.
