A comprehensive guide on minimizingambiguity in contractsTheProactive Legal Engineering toPrevent Costly DisputesDispute Resolution & ADR Insight March 2026Shield:BusinessIntroductionThe Business Shield:The most cost-effective legal strategy in business relationships is to avoid disputes, as theyare a predictable risk. Minimising ambiguity and conflict in legal documents such ascontracts and agreements, mortgages and leases, among others, reduces these predictablerisks, if not eliminating them. However, most businesses opt for a reactive approach, ratherthan being proactive to reduce such risk. Such thinking is expensive. Although legal defenseis good, a legal shield is much better.Proactive legal engineering entails implementing mechanisms to anticipate risks and deescalate costly disputes. The use of clear, conflict-minimising clauses, tiered disputeresolution mechanisms, and early dispute identification serves as a preventive shield againstcostly disputes.PredictableRiskProactiveShieldCostEffectiveWhy Proactive?Proactive Legal EngineeringThe Business Shield… 01Contract Design as PreventionKey Clauses that Minimise Ambiguity and ConflictVery often, the costliest contractual disputes do not arise from deliberate breaches, but fromcontracts that fail to anticipate practical difficulties in performance.1 Preventive contractdesign addresses this gap by creating agreements with clear, structured clauses to managefriction before it escalates into formal conflict.2Scope & Performance3When parties are aware of theirexact obligations, what has to be delivered, themilestones, and the measurable standards, itleaves no room for speculation and reducesinterpretive disputes.4 Vague wording, such as"reasonable efforts" or "as required", can lead todisagreements between expectations andperformance.Change ControlAddresses ownership changes or scopevariations. A clear step-by-step process(instructions, impact assessments, approval)allows changes to scope, time, or cost to bemanaged without disputes.Risk AllocationLiability should be placed on the party best ableto control risk, and the limit of the risk should beclear and appropriate insurance.5 This way, theparties are less likely to make opportunisticclaims and more willing to cooperate, especiallyin energy, project finance, and infrastructurecontracts.Notice & EscalationMechanisms for early warning and escalation areintended to have one party give formal notice ofthe problem, and then the parties engage in astructured discussion before any enforcementaction is taken. This way, the situation becomesmore transparent, and there is more room for asolution.TerminationThese clauses define when, how, and with whatconsequences a party can bring the relationshipto an end. At the end of the relationship, if theparties have to escalate and start litigation, thosesituations can be prevented if the termination isbased on what is very clearly stated, i.e., thereasons for termination, the notice period, and theoutcomes of the exit.Dispute ResolutionTiered dispute resolution clauses specify a stepby-step procedure for resolving disputes if andwhen they arise. It usually starts with partiesnegotiating in good faith. If necessary, they canthen pursue mediation or expert determinationbefore proceeding to arbitration, the primarybinding mechanism.Case Highlight Obrascon Huarte Lain SA v HM Attorney General for Gibraltar6The importance of these clauses was underscored in the UK High Court decision in Obrascon Huarte Lain SA v HMAttorney General for Gibraltar, a major infrastructure dispute. The conflict emanated from Sub-Clause 20. 1 of thecontract between the parties, which obligated the contractor to issue a timely notice for extension of time andadditional costs if there are overriding circumstances which prevented them from concluding the project within thestipulated timeline. The contractor neglected to give such notice as clearly as required under Sub-Clause 20.1.Ruling: The Court held that the contractor was not entitled to an extension oftime, having failed to comply with the clause.Proactive Legal EngineeringThe Business Shield… 02The tiered dispute resolution clause in anycontract serves as a step-by-stepescalation ladder, giving the parties anopportunity to resolve disputes at theearliest stage while saving time and costs.7It involves the following progressive stages:negotiation, mediation, and arbitration,before resorting to litigation.Negotiation is a business-level problemsolving mechanism focusing on preservingthe business relationship between theparties. Where negotiation fails, partiesproceed to mediation, which we call afacilitated negotiation with the assistance ofa third party. In the same vein, whenmediation fails, parties proceed toarbitration, which is more formal and closelyrelated to litigation. When mediation fails,parties proceed to arbitration, which is moreformal, and it is conducted in a privatesetting.According to Joseph Grynbaum, and in hiswords, “an ounce of mediation is worth apound of arbitration and a ton of litigation!”This underscores the fact that the earlier adispute is resolved, the less costly anddamaging it is.An ounce of mediation is worth a pound of arbitrationand a ton of litigation!”Joseph GrynbaumThe Tiered Dispute Resolution Clause:A Step-by-Step Escalation LadderProactive Legal EngineeringAn illustration of a tiered dispute resolutionclause is seen below:Where there are disputes arising out of orin relation to any issue regarding theinterpretation, performance, breach,termination or validity of this contract, theparties shall make efforts to negotiateand find a solution to the issues therein,within 20 days from the request of eitherparty to the other party. Where, after theexpiry of the 20 days, the parties have notreached a settlement to the issuestherein, either party, within 10 days fromthe expiry of such term, may refer thedispute to Mediation in accordance withthe Arbitration and Mediation Act 2023. Ifthe dispute remains unresolved, it shallbe finally settled by arbitration under therules of a designated arbitral institution,with the seat in Lagos, Nigeria, a solearbitrator, proceedings in English, and anaward that is final and binding. Nothing inthis clause prevents either Party fromseeking interim or conservatory relieffrom a court of competent jurisdiction,enforcing an arbitral award, or addressingmatters not capable of settlement byarbitration.8The Business Shield… 03Businesses are advised to implement practical systems to detect potential problems orbreaches before they escalate into costly legal disputes. Practical systems, such as theestablishment of a Joint Governance Committee and the creation of a real-time relationshipdashboard, are operational tools businesses must have.Joint Governance Committeesrepresentatives of the parties to a contractserve as a relationship-management boardthat monitors contracts, discusses risksbefore they escalate, resolves operationaltensions, and aligns expectations whenbusiness reality changes.9 It is expected thatboth parties meet regularly to overseethese relationships.Oversee Relationships RegularlyReal-Time Relationship Dashboardsuse data and tracking tools to monitor thefunctioning of the business relationship. Itis expected to track payment timelines,compliance deadlines, risk flags, anddelivery milestones, amongst others.Data-Driven MonitoringStrategic BenefitBusinesses that adopt such operational tools are more inclined to prevent disputesthrough design rather than fight them after damage is done.Operational ToolsJoint Governance Committees & Real-Time Relationship DashboardsProactive Legal EngineeringThe Business Shield… 04Preventive contract drafting is quite ineffective if it is not backed by appropriate institutionalbehaviour that enables its implementation. It is a common misconception that most disputesarise from the absence of preventive clauses. However, it is often the case that thecommercial teams responsible for contract performance are unaware that contractthresholds have been breached.InstitutionalBehaviourIssueIdentificationSpecificWorkshopsHence, a cultural change is necessary to treat the identification of potential problems as aprimary commercial responsibility, rather than a legal afterthought. Commercial teamsshould be instructed to interpret contracts as performance guidance frameworks ratherthan merely as legally binding documents.In reality, this implies the ability to identify legally significant events, such as variations,delays, force majeure triggers, and notice deadlines, in real time. Industries such asconstruction and energy, and long-term infrastructure projects, are examples where failingto promptly recognise these events can lead to the loss of contractual rights. Therefore,specific workshops should focus on key contractual provisions, including noticerequirements, change processes, escalation clauses, and conditions precedent.The Strategic AimThe aim is to ensure that parties understand the importance of addressing issuesthrough contractual mechanisms and formal resolution, while maintaining the continuityof commercial solutions.Training Commercial TeamsIn Early Issue IdentificationCulture ShiftThe Business Shield… 05Disputes are expensive and disruptive, but many can be avoided. Proactive legalengineering helps businesses prevent conflicts by using clear, unambiguous contracts, stepby-step dispute-resolution clauses, and practical execution structures. When issues areidentified early and handled properly, they are less likely to escalate into formal disputes.Benefits of PreventionSave Time & MoneyMinimizing costly litigationand operational delays.Strong RelationshipsMaintaining commercial continuitythrough collaboration.Reliable ResultsAchieving efficient projectoutcomes with less friction.Moreover, training commercial teams to detect and resolve issues at the earlieststage also reduces risk.
