What is a Reinsurance Agreement?
Reinsurance is central to the London market and to United Kingdom insurers generally. Agreements are usually either treaty reinsurance, covering a defined class of business automatically, or facultative, covering an individual risk. The Insurance Act 2015 applies to reinsurance as non-consumer insurance, so the duty of fair presentation and the reformed remedies for breach are directly relevant. Because a reinsurance contract responds to the cedant's own liabilities, the interaction between the two contracts is the source of most disputes.
About the Reinsurance Agreement
A Reinsurance Agreement transfers part of an insurer's risk to a reinsurer in exchange for premium. Under England and Wales law it is a non-consumer insurance contract governed by the Insurance Act 2015, and its value depends less on the headline limit than on how it interlocks with the underlying policies.
When do you need this document?
You need a Reinsurance Agreement when an insurer wants to write business beyond its own appetite or capital, to protect its results against a single large loss or an accumulation of losses, or to support a new class of business. Treaty cover suits a whole portfolio written automatically; facultative cover suits an individual risk that is too large or unusual for the treaty to absorb.
What does it cover?
The agreement defines the business reinsured and the structure, whether a proportional share of premium and losses or a layer that attaches above a retention. It sets premium and any adjustment, and the exclusions that carve risks back out. The provisions that decide recoveries in practice are operational: whether the reinsurer follows the cedant's settlements and on what conditions, what claims cooperation or control the reinsurer has, and how losses aggregate into a single event, which is what determines how many retentions and limits apply. It also covers reporting, inspection, the cedant's insolvency, and run-off after termination.
Common pitfalls
The classic failure is a gap between the reinsurance and the underlying policies, so the cedant pays a claim its own wording covers but the reinsurance excludes. Back to back drafting is what prevents it. The second is aggregation: an event definition or hours clause that does not match how losses actually arrive can turn one recovery into many retentions, or the reverse, and it is usually the largest number in dispute. The third is a follow the settlements clause qualified so heavily that the reinsurer can reopen every settlement, which removes much of the certainty the cedant was buying.
Governing law
Applicable law
This Reinsurance Agreement is drafted to comply with England and Wales law. Key legislation includes:
- Insurance Act 2015: Applies to reinsurance as a non-consumer insurance contract. It imposes a duty of fair presentation on the cedant, replaces avoidance with proportionate remedies, and restricts basis clauses, all of which affect how the placement is documented
- Marine Insurance Act 1906: Remains the source of a number of general insurance law principles, including insurable interest and aspects of the law on warranties as modified by later legislation. Still cited in reinsurance disputes
- Financial Services and Markets Act 2000: Makes effecting and carrying out contracts of insurance, including reinsurance, a regulated activity. The agreement should confirm the reinsurer's authorisation or applicable exemption for the territories concerned
- Third Parties (Rights against Insurers) Act 2010: Allows a third party to proceed directly against an insurer where the insured is insolvent. Relevant to how reinsurance responds when the cedant itself becomes insolvent
- Contracts (Rights of Third Parties) Act 1999: Determines whether anyone other than the contracting parties can enforce the agreement. Typically excluded, since reinsurance is intended to respond only to the cedant
- Arbitration Act 1996: Governs arbitration seated in England and Wales, which is the usual dispute mechanism in reinsurance treaties. It shapes the tribunal's powers and the limited grounds for challenging an award
