In an increasingly complex and unpredictable global economic environment, businesses and legal practitioners face a persistent dilemma: how to draft contracts that provide both sufficient certainty and adequate flexibility in the face of inevitable change. Global markets are shaped by fluctuating commodity prices, geopolitical tensions, technological disruptions, pandemics, and shifting regulatory frameworks. In such a climate, traditional fixed-term, performance-specific contracts may struggle to keep pace with these evolving realities. The legal solution lies in crafting instruments that anticipate volatility while still offering parties the security they need to confidently transact. Striking this fine balance between flexibility and certainty is truly at the heart of modern commercial contract drafting.
The Purpose and Promise of Contract Law
At its core, contract law provides parties with the means to allocate future rights and responsibilities in a predictable, enforceable manner. It enables long-term commitments, commercial planning, and the allocation of risks. A well-crafted contract lays out exactly what needs to be performed, by whom, in what manner, and according to what timetable. In ideal conditions, these precise provisions provide clarity and reduce the likelihood of disputes.
However, the hallmark of modern markets is not stability but disruption. Fixed obligations, once an asset, can become a source of contention when surrounding circumstances change dramatically. A delivery date that once seemed generous can become onerous when supply chains grind to a halt or freight prices surge. Price terms rooted in past assumptions may become intolerable in the face of inflation, sanctions, or currency volatility.
Certainty and flexibility are, in this context, contrasting values. The former comforts risk-averse parties by providing firm ground on which to base decisions and investments. The latter allows businesses to adapt, pivot, and survive when the environment shifts. The challenge lies in ensuring that one does not come at the total expense of the other.
The Lure of Rigidity: Why Parties Favour Certainty
One may ask why parties still favour rigid contractual terms when volatility has become the new norm. The answer is multifaceted.
Firstly, certainty supports accountability. Clear-cut obligations and timeframes hold parties to a shared standard of performance and provide less room for opportunistic reinterpretation. For example, in supply agreements, specifying delivery locations, product specifications, pricing mechanisms, penalties for delays, and exact quality metrics helps prevent disputes.
Secondly, banks and investors often favour contracts that deliver fixed, predictable cashflows. Infrastructure projects, energy supply agreements, and long-term lease arrangements commonly rely on rigid terms to satisfy lenders seeking stable returns. In such contexts, flexibility might raise concerns about undefined risk exposure.
Thirdly, certainty allows for easier legal enforcement. Courts and arbitral tribunals generally prefer dealing with definitive terms rather than loosely framed provisions. The fewer terms left open for interpretation, the less likely time-consuming and costly litigation becomes.
There is undeniable comfort in locking in terms. However, the more rigid a contract, the higher the risk that it will no longer be fit for purpose if market or operational conditions fluctuate significantly. Thus, the need arises to strategically build contracts with targeted flexibility.
Contract Clauses that Embrace Change
To introduce adaptability into commercial agreements, lawyers and business professionals have developed a suite of contractual tools and drafting techniques. These mechanisms do not eliminate uncertainty, but they make it manageable.
A fundamental tool is the inclusion of force majeure clauses. These provisions excuse one or both parties from performance when extraordinary events occur—typically listed as wars, natural disasters, pandemics, government actions, or economic upheavals—beyond the control of the parties. Carefully drafted, force majeure clauses can offer a measure of protection without bringing an entire transaction to a halt. However, they are traditionally used to suspend, rather than permanently alter, obligations.
Hardship clauses go further by acknowledging that extreme economic changes may fundamentally alter the balance of a contract. Unlike force majeure, which implicates impossibility or extreme difficulty, hardship speaks to situations where performance is still possible, but unjust or commercially devastating. These provisions often allow for renegotiation and, failing that, a legal right to terminate or revise the agreement. This tool is common in civil law jurisdictions and is increasingly seen in international contracts governed by soft-law instruments such as UNIDROIT principles.
Price adjustment mechanisms offer more granular flexibility. In long-term commodity or supply contracts, indexation clauses can link prices to inflation, commodity benchmarks, or currency exchange rates. This helps future-proof agreements and maintain economic equilibrium. Similarly, “review periods” may be institutionalised into agreements, whereby parties revisit key terms annually or biannually to align them with prevailing market trends.
Material Adverse Change (MAC) clauses are another instrument, particularly prevalent in M&A deals. These provisions allow an acquirer or investor to walk away from a transaction if significant negative changes affect the target’s business or the wider market. The scope of MAC clauses has been fiercely negotiated in the wake of COVID-19, with parties trying to either include or exclude pandemics and similar systemic shocks from the list of adverse events.
Change of law clauses address regulatory risk by allowing parties to renegotiate or escape obligations if legal changes render the contract more burdensome or illegal. These clauses are increasingly important in sectors susceptible to government intervention, such as energy, real estate, and financial services.
Lastly, performance standards themselves can sometimes be drafted in more flexible terms. Instead of dictating exact duties, contracts may oblige parties to use “best efforts” or operate “in good faith”. While these terms introduce softer obligations that can be harder to enforce, they also signal a commitment to cooperation. In an uncertain market, this may provide an essential lifeline.
Balancing Control and Collaboration in Contractual Relationships
As commercial arrangements grow more complex, successful contracts are no longer simply about clear-cut allocations of responsibility but about the governance of relationships. Long-term strategic agreements—joint ventures, outsourcing contracts, and development partnerships—require models that allow evolution without constant renegotiation.
To this end, contracts increasingly rely on governance structures. These may include steering committees, escalation ladders for problem-solving, mandatory mediation before litigation, and review mechanisms. Such structures allow issues to be resolved collaboratively, reducing the risk of breakdowns.
Relational contracts are a rising paradigm in this context. Originating from sociological and behavioural theories, they recognise that some business arrangements rely more on trust, adaptation, and mutual benefit than strict obligations. Although still contentious in terms of legal enforceability, relational contracts may include shared objectives, principles of fairness, and joint decision-making protocols. While they weaken legal certainty, they integrate flexibility into the DNA of the agreement.
The Enforcement Challenge: Will Courts Honour Flexibility?
One of the reasons parties fear flexible drafting is the uncertainty of judicial enforcement. Courts may hesitate to interpret broadly worded clauses or subjective standards like “good faith” or “commercial reasonableness”, especially in common law jurisdictions.
In English law, the doctrine of frustration—used to excuse performance under radical changes—remains narrow and sparingly applied. Similarly, the English courts have historically been reluctant to imply terms unless absolutely necessary, and have shown scepticism toward broad standards of co-operation not hardwired into contracts.
However, attitudes are evolving. Courts in various jurisdictions increasingly acknowledge the complexities of modern commerce and the need for balanced assessments of unforeseeable events. The widespread disruption caused by COVID-19, for example, led to greater scrutiny of force majeure clauses, and more judicial receptiveness to hardship arguments, especially in civil law jurisdictions.
Arbitration offers a slightly different platform. Arbitral tribunals, often composed of commercial experts, show more willingness to accommodate flexible arrangements and interpret them pragmatically. This may push more parties toward alternative dispute resolution when seeking to deploy more adaptable contract models.
Sector-Specific Approaches to Managing Uncertainty
Certain industries have taken more proactive approaches to incorporating adaptability into their contractual frameworks. The energy sector, characterised by long-term, capital-intensive projects, often leads in this regard.
Offtake agreements in liquefied natural gas, for instance, may include complex pricing formulae, delivery flexibility, and take-or-pay clauses combined with renegotiation triggers. This balance ensures that producers recover costs while buyers are not locked into uneconomic prices.
In construction, bespoke contracts such as NEC3 and NEC4 in the UK actively promote a collaborative, project management-led approach. They encourage early warning mechanisms, compensation events, and continual risk assessment, distinguishing them from traditional lump-sum contracts.
Tech partnerships and software services contracts also favour adaptability. Service Level Agreements (SLAs), agile development clauses, and phased deliverables help structure evolving expectations and timelines. The unpredictability of innovation, integration challenges, and user needs require ongoing dialogue and responsiveness.
Meanwhile, the finance sector employs contingencies such as interest rate swaps, debt covenants with performance-adjusted terms, and “accordion” features that expand or contract credit limits based on market movements.
Each of these industries demonstrates that there is no one-size-fits-all solution. Effective contract design must align with sector norms, legal constraints, and the commercial imperatives of the parties involved.
Cultural and Legal Differences Across Jurisdictions
One crucial consideration in cross-border contracting is the jurisdictional context for determining how much flexibility is permissible and enforceable. Civil law systems, such as those of France and Germany, tend to respect concepts such as hardship, renegotiation, and the doctrine of changed circumstances more readily than the English common law, which remains relatively formalist.
For international contracts under the auspices of instruments like the UN Convention on Contracts for the International Sale of Goods (CISG), UNIDROIT Principles, or EU law, there may be additional harmonised approaches to the treatment of flexibility.
It is essential, therefore, for contract drafters engaged in cross-border work to take account not only of governing law, but also of enforcement venue, local interpretation traditions, and extraterritorial regulatory effects.
Strategies for Drafting in an Unpredictable World
As markets continue on their unpredictable paths, a more nuanced approach to contract drafting becomes imperative. Here are key strategies to bear in mind:
Clear identification of foreseeable risks. Drafters should explicitly identify and address major foreseeable risks—supply chain disruption, currency fluctuations, regulatory changes—and decide how these are to be managed.
Tiered flexibility. Combine short-term obligations with intermediate and long-term review mechanisms. This layered approach balances immediate performance with longer-term adaptability.
Escalation and governance procedures. Build in methodologies for structured renegotiation, escalation of disagreements, and joint review of progress when performance is affected by external factors.
Avoid vague references. While flexibility is needed, ambiguity may lead to unwelcome interpretation battles. Terms such as “reasonable efforts”, “economic hardship”, or “good faith” must be defined where possible.
Consider soft law instruments. Where relevant and acceptable, incorporate or refer to principles embedded in instruments like the UNIDROIT Principles or sector-specific standards to lend cohesion and predictability to flexible terms.
Collaborate across disciplines. Contract drafters should collaborate with finance professionals, project managers, and operational leads to ensure that flexibility mechanisms are commercially realistic and administratively manageable.
Use scenario planning. Build multiple contingencies into larger contracts to allow for “Plan B” options without terminating them outright.
Reduce to writing. All understandings around flexibility should be committed to paper. Verbal assurances or informal understandings, however cooperative at the time, risk disintegration in future conflicts.
Looking Forward: The Evolution of Commercial Contracting
As the commercial and legal environment evolves, so too must our conceptions of what a contract is supposed to achieve. The dichotomy between flexibility and certainty is not going away; rather, it will sharpen as climate change, global health shocks, and technological acceleration continue to reshape commerce.
Legal innovation and cultural change are already in motion. Smart contracts powered by blockchain technologies are pushing new boundaries in conditional execution, potentially automating changes based on pre-agreed data triggers. At the same time, sustainability clauses and ESG (Environmental, Social, Governance) obligations are threading softer social aims into formally binding instruments, requiring a rethinking of performance expectations.
The most effective contracts will be those that balance the stability parties need to proceed with confidence, and the adaptability required to prosper in the unknown. This is both an art and a legal science—asking contract drafters to think beyond precedent, beyond existing risk models, and into uncharted territory. Whether through innovation, collaboration, or foresight, the future of contracts will rest on their ability not to withstand chaos, but to dance with it.
