Practice Succession & Sale

The essentials

Why Succession Planning Matters

Practice succession planning ensures continuity for clients, protects practice value, and provides financial security for retiring partners. Without proper planning, practices often sell for significantly less than their potential value, or fail to find buyers at all.

Successful succession typically requires 3-5 years of planning. This allows time to develop junior partners, improve practice systems, optimise profitability, and identify suitable buyers or successors. Early planning maximises value and reduces stress during transition.

Practice Valuation Methods

Law firm valuation involves several approaches:

  • Multiple of recurring fees (typically 0.8-1.5x annual fees)
  • Goodwill valuation based on client relationships and practice reputation
  • Asset-based valuation for work in progress and physical assets
  • Discounted cash flow analysis for larger practices
  • Market comparison with recent similar practice sales

Practice area, client retention rates, fee earner stability, and systems quality all affect valuation. Specialist legal sector accountants understand these factors and can provide realistic valuations.

Preparing Your Practice for Sale

Maximising practice value requires preparation across several areas:

  • Clean financial records and systems documentation
  • Reducing key person dependency and developing junior fee earners
  • Improving profitability and reducing lock-up
  • Ensuring SRA compliance and clean regulatory record
  • Documenting client relationships and matter management systems
  • Addressing any outstanding issues or liabilities

Tax-Efficient Exit Strategies

Practice sale proceeds may qualify for Business Asset Disposal Relief (formerly Entrepreneurs' Relief), reducing Capital Gains Tax to 18% (from 6 April 2026) on qualifying gains up to the £1 million lifetime limit. Structuring the sale correctly ensures maximum tax efficiency.

Consider phased retirement, earn-out arrangements, and pension contributions as part of your exit strategy. Each approach has different tax implications and risk profiles. Specialist advice ensures you choose the optimal structure for your circumstances.

Internal Succession Options

Internal succession to junior partners or employees often provides better outcomes than external sale. It maintains client relationships, preserves practice culture, and can be structured flexibly over several years. However, it requires developing successors with both technical capability and commercial acumen, plus financing arrangements for the purchase.

How Is Goodwill Taxed When a Law Firm Is Sold? A Solicitor's Guide to Capital Disposal, BADR and Section 162

When a law firm is sold, goodwill is a capital disposal charged to Capital Gains Tax, not trading income. Business Asset Disposal Relief can cut the rate on qualifying gains, but the rate now varies by the date of disposal and the conditions are strict. Section 162 incorporation relief can defer the charge, and the buyer's own goodwill relief depends on when and from whom the goodwill was acquired.

How Is WIP Treated on a Law Firm Sale? Why Work in Progress Is Taxed as Income

On a law firm sale, work in progress (WIP) and debtors are an income item, not a capital one. Unbilled time and unpaid bills are brought into account as a trading receipt taxed at income tax rates plus Class 4 NIC, while goodwill is a capital asset taxed at CGT rates. This guide explains the split, the statute behind it (ITTOIA 2005 ss.182 to 185), how WIP is valued under FRS 102, and why the sale agreement must separate the two.
