Claims co-operation clauses (reinsurance)

Which relationship the clause governs

The clause sits in the contract between the ceding insurer and the reinsurer — a treaty wording or a facultative slip — and not in the policy issued to the underlying insured. The insured is not a party to it and generally has no rights under it. That distinction is worth stating plainly because the phrase “claims cooperation clause” is also used, loosely, for the condition in a direct policy requiring the policyholder to assist its insurer. That different provision is covered separately in this wiki under cooperation clause.

The reinsurance clause exists because the reinsurer is paying a large part of the loss but has no contractual relationship with the claimant, no file, and no control over the lawyers. It buys information and a voice.

What a co-operation clause typically requires

A typical clause obliges the cedant to give immediate or prompt notice of claims or circumstances meeting a defined threshold; to provide the reinsurer with all information and documentation it reasonably requires; to consult the reinsurer on reserving, defence strategy, choice of lawyers and settlement; and, in stronger forms, to obtain the reinsurer’s agreement before settling or admitting liability.

Thresholds are usually expressed by reference to the reserve, to the likelihood of the reinsurance layer being reached, or to defined categories of claim — those raising coverage questions, those with a systemic or reputational dimension, or those involving named perils. What the clause does not do, in its co-operation form, is take the claim away from the cedant. Conduct, and the final decision, remain with the ceding insurer.

Co-operation versus control

A claims control clause is the stronger cousin. It gives the reinsurer the right to take over, or jointly to conduct, the investigation, defence and settlement of qualifying claims — to appoint or approve solicitors, to direct strategy, to require or refuse a settlement offer, and to attend mediations. The distinction is between being informed and consulted, and deciding.

The choice between them is a real commercial negotiation. Reinsurers writing large lines, particularly on facultative placements, will often press for control; cedants resist because control clauses can cut across their obligations and relationships with their own policyholder, and because a reinsurer directing a defence may not be aligned with the cedant’s regulatory duty to treat its customer fairly. Many wordings settle in the middle: consultation and consent rights on settlement, without transfer of conduct.

Condition precedent or not

The single most important drafting question is whether the clause is expressed as a condition precedent to the reinsurer’s liability. If it is, a failure to notify within the stipulated time or to obtain consent before settling can defeat the recovery entirely, regardless of whether the reinsurer was actually prejudiced. If it is not, breach sounds in damages, and the reinsurer must show what it lost.

Clauses that combine a short notification period with condition precedent status are the ones that generate disputes, because claims departments handling high volumes miss deadlines on files whose severity only becomes apparent later. Cedants should look at how the trigger is defined — awareness of a claim, of a circumstance, or of a claim likely to exceed a figure — and at whether the clock starts on receipt or on knowledge at the appropriate level of seniority.

Interaction with follow the settlements

Reinsurance contracts commonly include a follow the settlements provision, under which the reinsurer agrees to be bound by settlements properly made by the cedant. A claims control or strict consent clause pulls in the opposite direction: it reserves to the reinsurer a decision that the follow-the-settlements clause would otherwise leave with the cedant.

Where both appear, the relationship between them has to be read carefully. A settlement made in breach of a consent requirement is unlikely to attract the protection of a follow-the-settlements clause. Conversely, a well-drafted co-operation clause that requires only consultation leaves the follow-the-settlements protection intact. Getting the two provisions to work together is a wording exercise that should be done at placement, not discovered at claim.

Practical points for cedants and brokers

Map the notification triggers across the whole reinsurance programme, because a risk may be ceded to several contracts with different thresholds and different consequences for breach. Build the thresholds into the claims system rather than relying on individual handlers to remember them. Record consultation, not just decisions, so that compliance can be evidenced years later. And when a control clause is unavoidable, negotiate an express carve-out preserving the cedant’s ability to comply with its regulatory obligations to its own policyholder.

Professional indemnity placements illustrate both forms well, and the specific PI applications are treated in detail elsewhere in this wiki.

Frequently asked questions

Is a claims co-operation clause the same as a claims control clause?

No. A co-operation clause obliges the ceding insurer to inform and consult the reinsurer while keeping conduct of the claim. A control clause transfers conduct — the right to appoint lawyers, direct strategy and decide on settlement — to the reinsurer.

Does the underlying policyholder have rights under a reinsurance claims clause?

Generally no. The clause is a term of the contract between the ceding insurer and the reinsurer. The policyholder's obligations run under its own policy, typically through the cooperation clause in the direct wording.

What happens if the cedant misses the notification deadline?

It depends on whether the clause is a condition precedent to the reinsurer's liability. If it is, late notification can defeat the recovery whether or not the reinsurer suffered prejudice. If it is not, the reinsurer must show it was actually prejudiced and its remedy sounds in damages.

How does it interact with follow the settlements?

A consent or control requirement narrows the protection a follow-the-settlements clause otherwise gives the cedant, because a settlement made without the required consent is unlikely to bind the reinsurer. The two clauses should be reconciled at placement.
