The entire agreement clause (or whole agreement clause) is one of the most important boilerplate clauses. It has received extensive analysis by the courts and has frequently been the subject of litigation.
The purpose of an entire agreement clause should be to provide certainty as to what has been agreed and to reduce the risk of disputes between the parties. These clauses are intended to prevent the parties to an agreement from claiming that statements made during contract negotiations or otherwise (which are not included in the final written agreement) constitute additional terms of the agreement or a side agreement. An entire agreement clause generally provides that the written contract in which it sits constitutes the whole agreement. Most entire agreement clauses also include wording which seeks to restrict liability for claims based on misrepresentation.
The general approach of the courts has been to construe entire agreement clauses strictly. The Court of Appeal in AXA Sun Life Services Plc v Campbell Martin Ltd and Others stated that if a party wants to effectively exclude liability for a representation or other statement, a clear statement to that effect will be required. As such, a standard approach to drafting these clauses has been adopted.
Typically, an entire agreement provision comprises an entire agreement statement, declaring that the documents in which it appears, and any document referred to therein, contain the totality of the parties’ bargain. It may also include provisions which seek to prevent claims for misrepresentation, such as:
Courts have been interpreting entire agreement clauses in the context of the contract as a whole, in line with the case of Wood v Capita, where the Supreme Court found that contractual provisions cannot be interpreted in isolation.
In consequence, despite the strict interpretation approach under AXA Sun Life v Campbell, in NF Football Investments Ltd v Group Holdings Limited the High Court found that, when considering the context of the contract as a whole, an entire agreement clause may exclude liability for misrepresentation even if there is no express reference to misrepresentation.
This highlights the dangers of relying on a rigid approach to the interpretation of standard boilerplate clauses without considering the rest of the provisions under the contract. A party to an agreement should be mindful, in any event, when relying on representations made by another party, whether these take the form of correspondence, discussions, negotiations, promises or otherwise, insofar as such representations are not expressly contained within the agreement.
Equally, it is risky to rely on the courts taking a more holistic approach when interpreting standard boilerplate clauses, and it is safer to include the full standard entire agreement and misrepresentation claims exclusion clause in order to avoid potential disputes.
Case law has confirmed that an entire agreement clause in a contract will not prevent terms from being implied into it by the courts. Implied terms have been regarded as an unexpressed part of the contract itself (as opposed to a collateral warranty or a pre-contractual representation).
Terms can be implied in different ways including, amongst others, by statute, by custom or usage, or by reason of business efficacy. An example of the latter is the case of Hipwell v Szurek, where the court held that a term could be implied where it was necessary to give business efficacy to the contract.
The lease in question failed to contain an express provision stating which party was responsible for the exterior of the premises or their electrical supply. As such, to ensure that the lease did not lack commercial or practical coherence, the Court of Appeal found that there was a “plain and obvious gap” in the lease and implied a covenant on the part of the landlord to ensure the electrical supply was safely installed and covered by any requisite certificate.
Accordingly, if the parties wish to exclude any specific implied terms within an agreement, they must do this expressly and should not attempt to rely on the entire agreement clause for this purpose. It is important to use express, clear and concise language in relation to the types of implied terms which the parties may be seeking to exclude.
Entire agreement clauses must also be reasonable under the Unfair Contract Terms Act 1977. If the parties are both commercial entities and the contract is made in a commercial context, it is unlikely that an entire agreement clause excluding liability for pre-contractual representations would be deemed unreasonable.
This may be the case even where one of the parties is much larger than the other, provided that the smaller party is used to dealing with such agreements.
Entire agreement clauses are valuable provisions which provide certainty regarding the nature and scope of an agreement, and it is recommended that careful drafting is applied within the context of the agreement.
Parties should be aware that entire agreement clauses are frequently litigated in circumstances where the alleged wrongdoer seeks to rely upon the clause to argue that the innocent party cannot rely upon pre-contractual representations.
Accordingly, if a party wants to effectively exclude liability for misrepresentation, a clear statement to that effect will be required, although liability for fraudulent pre-contractual representations cannot be excluded. The general approach of the courts has been to construe entire agreement clauses strictly, in the same way as they do exclusion clauses. However, when the courts interpret entire agreement clauses, the contractual context is key.
