Partner vs Third Party Disputes UK: Guide

Overview

A partner-third party dispute is any disagreement between a business partnership (or its individual partners acting for the firm) and someone outside the partnership. That third party could be a supplier, customer, contractor, employee, landlord, lender, competitor, or regulator. The legal footing of the dispute depends on how the partnership is structured.

In a general partnership governed by the Partnership Act 1890, each partner can usually bind the firm to contracts made in the ordinary course of business, and partners tend to be jointly liable for the firm's debts and obligations. Limited Liability Partnerships (LLPs) work differently: the LLP itself is a separate legal entity and generally carries liability, not the individual members.

Understanding which structure you operate under matters, because it changes who can be sued, who signs what, and who ultimately pays if things go wrong. Most disputes are resolved through negotiation or correspondence long before anyone sets foot in a courtroom, but knowing your position early puts you in a much stronger place to settle on sensible terms.

Key steps

1. Gather the facts and paperwork. Before reacting, pull together every relevant document: the contract, purchase orders, emails, invoices, text messages, meeting notes and anything else that shows what was agreed and what happened. A clear timeline of events is often the single most useful thing you can build at this stage, and it will shape every decision that follows.
2. Check your partnership position. Look at your partnership agreement (or the LLP members' agreement) to see how decisions about disputes are taken, whether one partner can act alone, and how costs or liabilities are shared between partners. If there is no written agreement, the default rules under the Partnership Act 1890 will usually apply, and partners generally need to agree on the approach.
3. Open a written dialogue with the other side. Most disputes are better resolved by a calm, factual letter than by silence or a shouting match. Set out what you understand the position to be, what you want to happen, and a reasonable deadline for a response. Keep the tone professional, because anything you write could later be seen by a judge.
4. Consider alternative dispute resolution. Mediation, negotiation and, for some contracts, arbitration are often quicker and cheaper than court. Many commercial contracts require the parties to attempt ADR before issuing proceedings, and courts in England and Wales expect parties to have tried to resolve matters sensibly before litigating.
5. Take formal action if necessary. If the dispute cannot be resolved informally, formal routes may include issuing a letter before claim under the relevant pre-action protocol, bringing a claim in the County Court or High Court, defending a claim made against the partnership, or responding to an employment tribunal claim. Timing can matter a great deal because limitation periods apply, so do not let things drift.
