For a sole practitioner solicitor, succession planning is not an optional exercise. It is a professional obligation under the SRA Principles and a practical necessity for protecting clients, preserving practice value, and ensuring regulatory compliance. Without a plan, illness, retirement, or unexpected events can leave clients stranded, files unmanaged, and the SRA asking difficult questions.

This guide explains how a sole practitioner solicitor can structure a succession plan that works for the practice, the clients, and the regulator. We cover the key stages: timing, valuation, locum agreements, client transfer mechanisms, and the SRA requirements you must meet.

Why Sole Practitioner Succession Is Different

A sole practitioner solicitor carries all the risk and all the responsibility. Unlike a partnership or LLP, there is no automatic successor. The practice is tied to one person's practising certificate, one COLP designation, and one COFA role. When that person steps away, the practice stops unless a plan is in place.

The SRA expects every firm to have a succession plan. Principle 8 requires solicitors to run their business in a way that protects clients and the public interest. For a sole practitioner, that means ensuring continuity of service. The SRA's SRA Accounts Rules also require proper handling of client money during any transition.

Without a plan, the SRA may intervene, appoint a manager, or close the practice. Clients lose access to their files and money. The practice goodwill evaporates. A well-structured succession plan avoids all of this.

When to Start Planning

The short answer: now. The longer answer depends on your age, health, and intentions. As a rule of thumb, start formal planning at least three to five years before your intended exit date. If you are over 55, start immediately even if retirement is not imminent.

Consider these triggers for accelerating your plan:

  • Health changes that affect your ability to work full-time
  • A significant client loss or change in practice mix
  • Changes in the SRA regulatory framework or PII market
  • Personal circumstances such as divorce or caring responsibilities
  • An offer from a buyer or merger partner

Starting early gives you time to structure the deal, manage client transitions, and optimise tax outcomes. It also gives you room to train a successor or locum solicitor who can take over gradually.

Valuing Your Practice for Succession

Practice valuation for a sole practitioner solicitor is different from a multi-partner firm. The value is heavily dependent on the ongoing involvement of the principal. Most buyers discount sole practitioner goodwill because the clients are often personally loyal to the solicitor, not the firm name.

A typical valuation approach uses a multiple of normalised profit. For a sole practitioner, multiples range from 0.5x to 1.5x, depending on:

  • Recurring client base (conveyancing, wills, probate, family)
  • Quality of file management and digital systems
  • Staff retention and delegation
  • PII claims history
  • WIP and debtors quality

Worked example: A sole practitioner solicitor with normalised profit of £120,000 per year, a stable conveyancing and probate client base, and clean PII history might achieve a multiple of 1.2x. That gives a practice value of £144,000. Add net tangible assets (office equipment, leasehold improvements, cash in the client account) and WIP separately. The total consideration might be £180,000 to £200,000.

Structuring the Succession: Three Main Routes

Route 1: Outright Sale to Another Solicitor or Firm

This is the cleanest option. You sell the practice as a going concern. The buyer takes over the client files, staff, lease, and PII. You step away completely, usually with a handover period of three to six months.

Key considerations:

  • The buyer must be SRA-regulated and hold appropriate PII
  • Client consent is required for file transfer under the SRA Code of Conduct
  • You must notify the SRA of the change in ownership
  • Tax: the sale of goodwill is a capital gain, eligible for Business Asset Disposal Relief (BADR) at 14% in 2025/26, rising to 18% from April 2026. The lifetime limit is £1 million.

Worked example: Sale of goodwill for £150,000. After annual exempt amount (£3,000), the gain is £147,000. BADR at 14% gives tax of £20,580. Without BADR, the gain would be taxed at 24% (higher rate) = £35,280. The BADR saving is £14,700.

Route 2: Gradual Handover with a Locum or Associate

Many sole practitioners prefer a phased transition. You bring in a locum solicitor or salaried associate who gradually takes over client work. After a period of 12 to 24 months, the locum buys the practice or becomes the sole practitioner.

This route requires a locum agreement that clearly defines:

  • The locum's role and responsibilities
  • How client files are transferred
  • Fee-sharing arrangements during the transition
  • PII coverage (the locum must have their own or be covered by your policy)
  • Exit terms if the arrangement does not work

The SRA requires that the locum solicitor holds a current practising certificate and is registered with the SRA. If the locum works through a personal service company, IR35 may apply if your firm is medium or large. For more detail, see our guidance for locum solicitors.

Worked example: A sole practitioner with £150,000 annual fees brings in a locum solicitor on a 50:50 fee split for 18 months. The locum handles 60% of the client work. After 18 months, the locum buys the practice for £120,000 (goodwill plus WIP). The sole practitioner retires with a capital gain of £117,000 after costs, taxed at BADR rates.

Route 3: Merger with Another Firm

A merger can be a succession solution if you want to remain involved part-time or retire gradually. You merge your practice into a larger firm, becoming a consultant or salaried partner for a fixed period.

Key considerations:

  • The merger must be structured as a business combination, not a sale
  • Client consent is still required for file transfer
  • Tax treatment depends on whether the merger is a share-for-share exchange or an asset sale
  • PII implications: the merged firm must cover your previous work

SRA Compliance During Succession

The SRA does not require you to have a succession plan on file, but it expects you to have one. If you become incapacitated without a plan, the SRA can intervene. The Intervention Powers under the Solicitors Act 1974 allow the SRA to take control of your practice, close it, and distribute client money and files.

To avoid intervention, ensure your succession plan addresses:

  • Client money: The SRA Accounts Rules require that client money is properly held and accounted for during any transition. Your plan should name a solicitor who can access the client account and manage disbursements.
  • File transfer: Client consent must be obtained before files are transferred to a new solicitor. The SRA Code of Conduct requires you to inform clients of the proposed successor and give them the right to choose another solicitor.
  • PII run-off: You must maintain run-off cover for at least six years after ceasing practice. The cost is typically 1.5 to 3 times your last annual premium. Factor this into your exit budget.
  • COLP and COFA handover: If you are the COLP and COFA, you must nominate replacements or ensure the successor firm takes on these roles. See our COFA fundamentals guide for details.

Tax Planning for the Exit

Tax is a major factor in succession planning. The key areas to address:

  • Goodwill disposal: As noted, BADR at 14% (2025/26) or 18% (from April 2026) applies to the first £1 million of lifetime gains on qualifying business assets. Plan to use your BADR allowance before the rate rises.
  • WIP and debtors: These are usually sold as part of the practice. WIP is taxed as trading income in the year it is realised. Debtors are taxed when collected. Consider a staggered sale to spread the tax liability.
  • Pension contributions: If you have unused annual allowance from previous years, make large pension contributions before the sale to reduce your taxable income in the final year.
  • Capital allowances: Claim capital allowances on office equipment and fixtures before the sale. The buyer will want a clean balance sheet.

Worked example: A sole practitioner sells the practice for £200,000 (goodwill £150,000, WIP £30,000, debtors £20,000). The goodwill gain of £147,000 after the annual exempt amount is taxed at 14% BADR = £20,580. The WIP of £30,000 is taxed as trading income at 40% = £12,000. The debtors of £20,000 are taxed when collected. Total tax on the sale: approximately £32,580 plus NIC on the trading income element.

Client Transfer: The Practical Steps

Client transfer is the most sensitive part of succession. Clients have a personal relationship with you. They may be anxious about change. A structured process reduces risk and preserves goodwill.

Follow these steps:

  1. Identify the successor: Choose a solicitor or firm with the right expertise and PII cover. Ideally, introduce them to clients gradually over several months.
  2. Obtain client consent: Write to each client explaining the proposed transfer. Give them the option to choose another solicitor or to collect their files. The SRA requires this to be done in writing.
  3. Transfer files: Once consent is obtained, transfer the physical or digital files to the successor. Ensure a clear record of what was transferred and when.
  4. Notify the SRA: Inform the SRA of the change in ownership or cessation of practice. Use the SRA's online notification system.
  5. Close the client account: Once all client money has been distributed or transferred, close the client bank account. Ensure the final reconciliation is completed within five weeks of the last transaction.

If you are using a locum agreement, the locum solicitor can manage the client transfer process on your behalf. This is common in phased transitions.

Common Mistakes to Avoid

Based on our experience advising sole practitioner solicitors, these are the most common pitfalls:

  • No plan at all. The biggest mistake. Without a plan, the SRA may intervene and your clients suffer.
  • Underestimating PII run-off costs. Run-off cover can cost £10,000 to £30,000 per year for six years. Budget for this from the sale proceeds.
  • Ignoring the locum agreement. A verbal handshake with a locum solicitor is not enough. You need a written agreement covering fees, PII, and exit terms.
  • Failing to obtain client consent. Transferring files without consent is a breach of the SRA Code of Conduct and can lead to disciplinary action.
  • Overvaluing goodwill. Be realistic. A sole practitioner practice is worth less than a multi-partner firm. Overpricing will deter buyers.
