Common Commercial Disputes in the UK

Overview

Commercial disputes take many forms, but most arise when expectations in a business relationship break down. Common triggers include non-payment, failure to perform a contract, inaccurate pre-contract statements, misuse of confidential information, boardroom conflict, or disagreement over ownership rights and profit-sharing. These disputes can affect SMEs, owner-managed businesses, investors, partnerships, corporate groups and professional service firms. Early legal advice is valuable because the dispute type often determines the remedy, evidence strategy, limitation period and whether urgent action is needed. This article outlines the most common categories of commercial dispute and the key issues businesses should consider at an early stage.

Key Legal Principles

Common commercial dispute categories include:

• Contract disputes: interpretation, non-performance, defective performance, wrongful termination, price disputes and notice issues.
• Debt recovery disputes: unpaid invoices, account disputes, retention, set-off or disputed interest entitlement under Late Payment of Commercial Debts (Interest) Act 1998, ss 4-6.
• Misrepresentation disputes: allegations that one party entered a deal based on false pre-contract statements.
• Supply and services disputes: delay, quality failures, KPI or service level breaches, and exclusivity disputes.
• Shareholder and director disputes: deadlock, dilution, exclusion from management, misuse of company assets, breach of directors’ duties and unfair prejudice claims under Companies Act 2006, s 994.
• Professional negligence disputes: losses caused by solicitors, accountants, surveyors, brokers or other advisers.
• Confidentiality and restrictive covenant disputes: misuse of trade secrets, customer lists, pricing data or post-termination restrictions.
• Partnership and joint venture disputes: ownership, contribution, exit, fiduciary obligations and accounting disputes.
• Interim relief cases: urgent applications for injunctions to restrain conduct or preserve assets under Senior Courts Act 1981, s 37 and Civil Procedure Rules 1998, Pt 25.

Across these categories:

• pre-action conduct and ADR remain important.
• limitation can differ depending on whether the claim sounds in contract, tort or statute.
• the contract may contain a dispute resolution clause, jurisdiction clause or arbitration clause that changes the route to resolution.

What Evidence Is Usually Required?

• Contract documents, schedules, specifications and side letters.
• Purchase orders, invoices, statements and payment histories.
• Pre-contract presentations and written assurances.
• Emails showing performance complaints, waiver, variation or admissions.
• Corporate documents such as articles, shareholders’ agreements and board minutes.
• Technical reports, valuations or forensic accounting evidence.
• HR or access-log material in confidentiality disputes.
• Regulatory and Companies House records where relevant.

What Are the Available Options?

• Informal commercial discussions: Useful where trust has not entirely broken down. Best used for ongoing trading relationships.
• Solicitor-led settlement: Can narrow issues easily. Best used for most dispute types.
• Mediation: Often effective where relationships matter. Best used for contract, shareholder, partnership disputes.
• Expert determination: Narrow and specialist. Best used for valuation or technical pricing issues.
• Arbitration: Private and enforceable, but can be costly. Best used for where contract requires it.
• Court proceedings: Binding and coercive, but more public. Best used for complex or hard-fought disputes.

Common Risks or Mistakes

• Assuming the dispute is “just debt recovery” when there is a genuine cross-claim.
• Failing to identify an arbitration clause or exclusive jurisdiction clause.
• Treating a shareholder conflict as a simple employment fallout when company law remedies may be central.
• Ignoring urgency where confidential information or assets are at risk.

Underestimating the need for expert evidence in valuation or technical disputes.

Case Study from Alstern Solicitors

Background

A company approached Alstern Solicitors about an unpaid invoice claim against a commercial customer.

Challenge

On review, the dispute was not a straightforward debt claim; the customer alleged misrepresentation, defective performance and a right of set-off.

How We Assisted the Client

We reclassified the dispute properly, reviewed the contract and pre-contract materials, advised on the risks of summary debt proceedings, and moved the matter into a more appropriate pre-action and settlement framework.

Outcome

The client avoided procedural missteps and achieved a structured settlement that dealt with the wider dispute rather than only the headline invoice figure.

What Happens If You Choose the Wrong or Inexperienced Solicitor?

A poor adviser may categorise the dispute too narrowly, overlook key remedies, miss the need for urgent relief, or fail to identify contractual dispute mechanisms. That can lead to unnecessary escalation, wasted cost, and a weaker overall outcome.
