Every answer and its explanation appears here once you have finished the path. Each one then links to the matching glossary entry, where the concept is set out in full with its worked example.
1. Agreed value removed one disagreement and displaced another. Where do the opinions now clash?
On what agreed value does not govern: partial damage, restoration estimates and depreciation
An agreed value settles total loss by convention, and that is all it settles. The conflict therefore shifts mechanically to where it is silent, and that is a consequence to know before believing that agreeing the value removed valuation disputes: it removed one and concentrated the others. Answering that the expert procedure must establish the value is the exact error the module flags: settling the value of a painting whose value is already agreed would spend the procedure on the one question that does not arise.
Glossary entry · valeur-agreee2. The insured, in a hurry, writes to invoke the expert clause and appoint a third expert. The insurer had separately argued that an old restoration went undeclared. Where is the danger?
Invoking the expert procedure without expressly reserving the coverage point can amount to accepting that the loss is owed
You only argue the amount of something you owe, and that implicit reasoning is the trap. The insured risks winning 151,000 euros of argument while conceding the question worth 1.4 million. The letter was the right step sent at the wrong moment: the coverage point had to be reserved before entering the mechanism, in one sentence. And the expert clause could do nothing about it anyway, since it settles fact and never cover: a third expert states a rate, it does not state whether the peril was covered.
Glossary entry · fine-art-insurance3. The total gap is 151,000 euros. How does it break down, and where is the real subject?
25,000 euros on restoration, a classic technical disagreement, and 126,000 on depreciation, where the nine-point gap is the real subject
95,000 against 70,000 is 25,000 on restoration; 15 percent against 6 percent of 1.4 million is 210,000 against 84,000, that is 126,000 on depreciation. Breaking it down before arguing says where to put the effort, and here five sixths of the stake rests on a rate rather than on an estimate. That is also what makes it decisive to check exactly what the clause says about depreciation, since many wordings bind the third expert on value and stay silent on it.
Glossary entry · depreciation4. The module flags an unwritten threshold. Which, and where does it come from?
An economic threshold: sharing the fees means that below a certain gap the procedure costs more than it returns, and that is the price of its speed
Three experts on a file of this size consume a noticeable share of the 151,000 at stake, and the threshold appears in no text: it results from sharing the fees. That is why such gaps are often settled near the midpoint without anyone finding it fair, and it has to be set before starting rather than discovered along the way. Looking for it in the clause, as another answer suggests, means looking in the contract for a constraint that comes from the economics of the procedure.
Glossary entry · principe-indemnitaire5. On which three points is an expert clause read before entering it?
Who appoints if a party refuses, what happens if the experts cannot agree on the third, and whether the decision binds on depreciation
The three points share the feature of describing what happens when the mechanism jams, and that is where wordings differ most. With no fallback appointment, a refusal to nominate blocks everything; with no way out of a disagreement over the third expert, the procedure stops before starting; and with no mention of depreciation, you obtain a decision binding on what was already agreed and leaving open what carried five sixths of the stake. The other answers list real parameters that never prevent the procedure from concluding.
