Common PI Insurance Claims in Legal Practice

3 Feb 2026

Professional Indemnity insurance is not just a regulatory requirement for legal professionals in the UK. It is a safety net that protects firms from financial, reputational, and operational damage when something goes wrong. Even the most diligent solicitors and law firms face risks. A missed deadline, a drafting error, or a breakdown in communication can quickly turn into a costly claim.

This article explains the most common PI insurance claims in legal practice, why they occur, and how firms can reduce their exposure. It also highlights where working with a reliable PI Insurance Provider makes a real difference when a claim arises. For firms seeking clarity, practical examples, and risk-aware guidance, this guide offers a clear and grounded overview.

Missed Deadlines and Limitation Period Errors

Why Limitation Errors are So Common

Missing a deadline is one of the leading causes of PI insurance claims in legal practice. Courts and regulators take limitation periods seriously, and clients expect their solicitor to do the same. A single missed date can permanently bar a claim, leaving the client with no remedy other than pursuing the firm for negligence.

These errors often occur due to diary management failures, incorrect calculation of limitation periods, or assumptions made during file transfers. High workloads, staff turnover, and reliance on manual tracking systems increase the risk further.

Example from Legal Practice

A personal injury solicitor fails to issue proceedings within the statutory time limit after settlement discussions drag on longer than expected. The client loses the right to claim compensation and brings a PI claim against the firm for the full value of the lost case.

How Firms Can Reduce This Risk

Clear internal systems, dual diary entries, and regular file audits help reduce deadline-related errors. However, even robust systems can fail. That is why firms rely on a trusted PI Insurance Provider to step in when the worst happens and provide financial and legal protection.

Negligent Advice or Incorrect Legal Guidance

When Advice Leads to Financial Loss

Clients depend on their solicitor’s expertise to make informed decisions. When advice is incomplete, inaccurate, or based on outdated law, the consequences can be serious. Claims for negligent advice often arise in conveyancing, tax planning, employment law, and commercial contracts.

These claims are not always about obvious mistakes. Sometimes the issue is a failure to warn the client about risks, alternative options, or potential consequences.

Example From Legal Practice

A solicitor advises a client to proceed with a commercial lease without fully explaining the break clause. The client later discovers they are locked into a long-term obligation and suffers significant financial loss. The client claims the solicitor failed to provide proper advice.

Why PI Insurance is Critical Here

Disputes over advice often come down to interpretation and documentation. A strong PI Insurance Provider supports the firm through investigations, defence costs, and settlement negotiations, allowing the firm to focus on continuity rather than crisis management.

Errors in Drafting Legal Documents

Small Drafting Errors, Big Consequences

Drafting mistakes are another frequent source of PI claims. These can include incorrect clauses, ambiguous wording, missing provisions, or simple typographical errors that alter meaning. In legal documents, even a minor error can have major financial implications.

Contracts, wills, trusts, and settlement agreements are particularly high-risk areas. Clients expect precision, and courts interpret documents strictly.

Example from Legal Practice

A solicitor drafts a will but omits a residuary clause. As a result, part of the estate falls into intestacy, causing family disputes and financial loss to intended beneficiaries. A PI claim follows against the firm.

Preventive Steps Firms Can Take

Peer reviews, standardised templates, and final checks reduce drafting errors. Still, human error cannot be eliminated entirely. Having coverage from an experienced PI Insurance Provider ensures that when drafting issues arise, the firm is protected against potentially large claims.

Failure to Follow Client Instructions

Where Communication Breakdowns Lead to Claims

Clients expect their instructions to be followed accurately and promptly. Claims often arise when a solicitor misunderstands, overlooks, or deviates from those instructions without clear justification or written confirmation.

This issue frequently appears in litigation strategy, settlement decisions, property transactions, and corporate matters.

Example from Legal Practice

A client instructs their solicitor not to settle below a certain amount. The solicitor proceeds with a settlement without explicit approval, believing it to be in the client’s best interest. The client later alleges loss and brings a PI claim.

The Importance of Clear Records

Written confirmations, detailed attendance notes, and regular updates help reduce disputes. Even so, disagreements can still occur. Support from a dependable PI Insurance Provider helps manage both the financial exposure and the client relationship during a claim.

Conflicts of Interest and Breach of Duty

How Conflicts Create Professional Risk

Conflicts of interest are taken seriously by regulators and courts. Acting for multiple parties with competing interests or failing to disclose a potential conflict can quickly lead to PI claims.

Sometimes conflicts arise unintentionally, especially in smaller firms or niche practice areas where client networks overlap.

Example from Legal Practice

A firm acts for both the buyer and seller in a commercial transaction without fully assessing the conflict risks. When the deal collapses, one party alleges the firm favoured the other, resulting in financial loss and a PI claim.

Why Insurers Look Closely at Conflict Management

Insurers assess conflict procedures carefully when underwriting policies. A PI Insurance Provider experienced in legal practice understands these risks and can offer guidance alongside cover, helping firms strengthen internal compliance.

Inadequate Supervision and Delegation Errors

When Oversight Failures Lead to Claims

Many PI claims arise not from senior solicitors’ actions, but from inadequate supervision of junior staff or outsourced work. Delegating tasks without proper oversight can lead to errors that the firm remains responsible for.

This is especially common in conveyancing, immigration work, and volume-based legal services.

Example from Legal Practice

A trainee solicitor handles a conveyancing matter with limited supervision. A title defect is missed, and the client later suffers a financial loss when selling the property. The firm faces a PI claim due to inadequate supervision.

Managing Supervision Risk

Clear supervision structures, training, and accountability reduce exposure. Even with safeguards, firms benefit from working with a PI Insurance Provider that understands the realities of legal team management and responds effectively when supervision-related claims arise.

Breach of Confidentiality and Data Handling Errors

a) A Growing Source of PI Claims

With increased reliance on digital systems, confidentiality breaches and data errors are becoming more common. Sending information to the wrong recipient, failing to secure client data, or mishandling sensitive documents can all trigger PI claims. These incidents often overlap with regulatory investigations and reputational damage.

b) Example From Legal Practice

A solicitor accidentally emails confidential settlement details to the opposing party. The client claims the error weakened their negotiating position and caused financial loss, leading to a PI claim.

c) The Role of Insurance Support

While cybersecurity measures are essential, mistakes still happen. A responsive PI Insurance Provider helps firms manage claims, legal costs, and client communication following confidentiality breaches.

Conclusion: Turning Risk Awareness into Better Protection

PI insurance claims are an unfortunate reality of legal practice, not a reflection of poor professionalism. Even well-run firms with experienced solicitors can face claims due to human error, complex instructions, or unexpected circumstances.

Understanding the most common types of claims helps firms take practical steps to reduce risk. Strong systems, clear communication, proper supervision, and ongoing training all play a role. However, no risk management strategy is complete without the right insurance partner.
