Solicitor Professional Indemnity Insurance: Why It Matters When Selling a Property

When you sell a property, your solicitor handles some of the most important and high-value aspects of the transaction — from drafting the contract and managing enquiries to handling hundreds of thousands of pounds on completion day. If something goes wrong, the consequences can be severe: a collapsed sale, a title defect that reduces the property's value, or money sent to the wrong place.

Professional indemnity insurance (PII) is the financial safety net that protects you when your solicitor makes a mistake. This guide explains what PII is, what it covers, how to check your solicitor has it, and what other protections are available if things go wrong.

What is professional indemnity insurance?

Professional indemnity insurance is a type of insurance policy that covers professionals against claims for financial loss caused by their negligence, errors, or omissions. For solicitors, PII is not optional — the SRA Indemnity Insurance Rules require all regulated firms to hold a qualifying insurance policy at all times.

In practical terms, PII means that if your conveyancing solicitor makes a negligent error — such as failing to carry out a local authority search, missing a restrictive covenant, or making an error on the transfer deed — and that error causes you a financial loss, there is an insurance policy in place to pay your compensation. You do not need to worry about whether the solicitor or firm can personally afford to pay.

This is one of the key reasons why it is so important to use a properly regulated solicitor for your property transaction. Unregulated operators are not required to hold PII, leaving you with no insurance safety net if something goes wrong.

SRA minimum cover requirements

The SRA sets minimum levels of professional indemnity insurance that all regulated firms must hold. These minimums apply on a per claim basis, meaning each individual claim is covered up to the minimum amount:

Many firms, particularly those handling high-value residential or commercial property work, carry cover well in excess of the minimum. It is perfectly reasonable to ask your solicitor what level of PII cover their firm holds before you instruct them, especially if your property transaction involves a high-value property. See our guide on what to ask your solicitor before instructing for more questions you should consider.

How PII protects property buyers and sellers

PII is relevant to every stage of a property transaction. Whether you are buying or selling, your solicitor's insurance provides a financial backstop if their negligence causes you loss. Here are the most common ways PII protects you during a property sale:

During pre-contract work

Your solicitor must carry out due diligence on the property, including reviewing the title, ordering searches, and raising enquiries with the buyer's solicitor. If they fail to identify a critical issue at this stage — such as a defective title, an undisclosed planning restriction, or an adverse environmental search result — and that failure causes you financial loss after completion, PII covers the resulting claim.

At exchange and completion

The exchange and completion stages involve contractual deadlines and the movement of large sums of money. If your solicitor misses a completion deadline, fails to obtain the correct mortgage redemption figure, or makes an error in the financial completion statement, PII covers the financial consequences.

After completion

Some errors only come to light after the transaction has completed. For example, a title registration error at HM Land Registry, a missed restrictive covenant that prevents the buyer from using the property as intended, or a failure to discharge a charge on the title. Even if the mistake is discovered months or years later, PII is there to cover the claim (subject to the limitation period).

What is covered by PII

A solicitor's professional indemnity insurance policy typically covers the following:

• Negligence — Failure to exercise the skill and care expected of a reasonably competent solicitor, resulting in financial loss to the client
• Errors — Factual mistakes in documents, incorrect legal advice, miscalculations in completion statements, or wrong information provided to Land Registry
• Omissions — Failing to carry out necessary steps such as property searches, failing to report material information, or failing to meet critical deadlines
• Breach of duty — Failing to act in the client's best interests or to follow instructions properly
• Loss of documents — If the firm loses or damages important client documents, causing financial loss
• Defence costs — The insurer also covers the cost of defending the solicitor against the claim, even if the claim is ultimately unsuccessful

What is not covered by PII

While PII provides broad protection, there are important exclusions to be aware of:

• Deliberate fraud or dishonesty — If your solicitor intentionally steals client money, forges documents, or acts fraudulently, this is excluded from PII cover. The SRA Compensation Fund exists to address these situations instead.
• Criminal acts — Losses arising from a solicitor's criminal conduct are generally excluded.
• Trading debts — PII covers professional liability, not the firm's commercial debts or business losses.
• Claims outside the policy period — If the claim is made after the policy (including any run-off cover) has expired and no successor policy is in place, the insurer may not be liable.
• Losses unrelated to professional services — PII only covers claims connected to the legal services provided. Personal disputes or non-professional activities are not covered.

The SRA Compensation Fund: a separate safety net

The SRA Compensation Fund is entirely separate from professional indemnity insurance. It is a fund of last resort maintained by the SRA and financed by contributions from all regulated firms. The Compensation Fund provides grants (not compensation as of right) in two main situations:

• Dishonesty — Where a solicitor has dishonestly taken or misused client money
• Failure to account — Where a firm has failed to account for money that it held on behalf of a client

The Compensation Fund does not cover negligence claims — those are the domain of PII. However, it provides a vital safety net in the worst-case scenario where your solicitor has acted dishonestly and PII does not apply. If you find yourself in this situation, you can complain to the SRA and apply to the Compensation Fund simultaneously.

Comparison of protections available to you

The following table summarises the different protections available depending on what has gone wrong with your solicitor:

How to check if your solicitor has PII

All SRA-regulated firms must hold PII as a condition of their authorisation. The simplest way to check is:

1. Search the SRA register. Visit the SRA register and search for the firm by name or SRA number. If the firm appears as currently authorised, it is required to have valid PII in place. The register does not show the specific insurer or level of cover, but authorisation confirms the insurance requirement is met.
2. Ask the firm directly. You can ask your solicitor to confirm the name of their PII insurer, the level of cover, and the policy renewal date. A properly regulated firm will have no difficulty providing this information.
3. Check the terms of engagement. When you instruct a solicitor, they should provide a terms of engagement letter that includes information about their professional indemnity insurance and complaints procedure.

If a firm cannot or will not provide details of their PII cover, treat this as a serious warning sign. It may indicate that the firm is not properly regulated or that their insurance has lapsed.

What happens if a firm closes

Law firms can close for many reasons — retirement of partners, financial difficulties, regulatory intervention, or merger with another firm. If your solicitor's firm closes after handling your property transaction, the following protections apply:

Run-off cover

The SRA requires all firms to maintain run-off insurance cover for a minimum of six years after closure. Run-off cover is a continuation of the firm's PII policy that remains in force even though the firm is no longer trading. This means you can still bring a negligence claim against the firm's insurance even if the firm itself no longer exists.

For example, if your solicitor completed your property sale in 2024 and the firm closed in 2025, the run-off cover would remain in place until at least 2031. If you discover a conveyancing error during that period, you can claim against the run-off policy.

SRA intervention

If a firm is closed by the SRA (known as an intervention), the SRA appoints an intervention agent to take control of the firm's client files and client money. The intervention agent ensures that ongoing matters are transferred to other solicitors and that client interests are protected. You should receive notification from the SRA or the intervention agent about what has happened and how to recover your files.

The Third Parties (Rights against Insurers) Act 2010

If the firm has become insolvent or ceased to exist, the Third Parties (Rights against Insurers) Act 2010 allows you to bring a claim directly against the firm's PII insurer. You do not need to obtain a judgment against the firm first. This is an important statutory protection that ensures the closure of a firm does not leave you without recourse.

How PII claims work in practice

If you believe your solicitor has been negligent and you want to make a claim against their PII, the typical process is as follows:

1. Raise the issue with your solicitor first. Write to the firm setting out what went wrong, what financial loss you have suffered, and what you expect them to do about it. The firm is required to have an internal complaints procedure.
2. The firm notifies its insurer. Once the firm receives a complaint or claim that may be covered by PII, they are obliged to notify their insurer. The insurer then takes over the management of the claim, including appointing solicitors to investigate and respond.
3. Investigation and response. The insurer will investigate the claim, review the file, and assess whether the firm was negligent and whether the negligence caused your loss. This typically takes several weeks to a few months.
4. Settlement or defence. If the insurer accepts that the claim is valid, they will usually offer a settlement. If they dispute the claim, you may need to escalate to formal court proceedings. The vast majority of professional negligence claims settle before reaching trial.
5. Payment of compensation. If the claim is successful, the insurer pays the agreed compensation directly to you (or to your solicitor if you have instructed one to handle the claim on your behalf).

For straightforward claims of modest value, you may be able to handle the process yourself. For larger or more complex claims, it is advisable to instruct a specialist professional negligence solicitor. Many offer free initial assessments and no win no fee arrangements.

What to do if your solicitor's negligence causes you loss

If you believe your solicitor has been negligent during your property transaction, take the following steps:

1. Gather your evidence. Collect all correspondence with your solicitor (emails, letters, file notes), the terms of engagement letter, all conveyancing documents, and any evidence of the financial loss you have suffered. Create a timeline of events.
2. Complain to the firm. Write a formal complaint to the firm's complaints partner setting out the negligence, the loss, and the remedy you seek. Give them eight weeks to respond. For more detail on this process, see our guide on how to complain about your solicitor.
3. Escalate if necessary. If the firm does not resolve your complaint satisfactorily, you can escalate to the Legal Ombudsman for service complaints (awards up to £50,000) or bring a formal professional negligence claim through the courts.
4. Consider specialist legal advice. For claims involving significant financial loss, instruct a solicitor who specialises in professional negligence. They can assess the strength of your claim, handle the pre-action protocol, and negotiate with the insurer on your behalf.
5. Watch the time limits. You have six years from the date of the negligent act to bring a claim under the Limitation Act 1980, or three years from the date you discovered the negligence (subject to a fifteen-year long-stop). Do not delay — seek advice promptly.

PII and conveyancing costs

Professional indemnity insurance is one of the significant overhead costs for conveyancing firms. The premiums a firm pays depend on factors including the volume and value of transactions handled, the firm's claims history, the number of solicitors employed, and the areas of law practised. These costs are ultimately reflected in the conveyancing fees you pay.

This is worth bearing in mind if you are comparing quotes from different solicitors. A firm offering unusually low fees may be cutting corners elsewhere, or it may be an unregulated operator that does not carry PII at all. The cost of your solicitor's PII is, in effect, a small price built into your conveyancing fees that buys you significant financial protection.

Key dates in the PII cycle

The SRA operates a common renewal date for professional indemnity insurance. All regulated firms must renew their PII by 1 October each year. This is known as the PII renewal date, and it is a critical point in the regulatory calendar.

If a firm fails to obtain qualifying insurance by 1 October, it enters a "cessation period" during which it can only carry out limited activities (such as completing existing matters). If the firm still has not obtained insurance after the cessation period, the SRA can intervene and close the firm down. In practice, the vast majority of firms renew their insurance on time, but if you are instructing a solicitor in September or October, it does no harm to confirm that their insurance renewal is in order.
