Glossary

Glossary for solicitors: 16 terms in plain English

Each definition is taken from one of our guides, which gives the rule in full and where it comes from. The terms are in alphabetical order.

AI warning notice

The SRA's notice of 17 August 2026 on using AI in legal work. The firm remains accountable for work done through AI, every citation and assertion must be verified, and client information may only go into an AI system with contractual, technical and organisational safeguards.

Cancellation notice (client care)

The notice of the 14-day right to cancel that a firm must give an individual client who instructs at a distance or off the premises. Without it the cooling-off period can run for up to a year, and fees for work done inside it are at risk.

COLP and COFA

The compliance officer for legal practice and the compliance officer for finance and administration, which every SRA-regulated firm must have. A rule that would have stopped some managers of larger firms holding the roles was due in January 2027; the SRA paused it on 1 October 2026.

Desk-based review

An SRA anti-money-laundering inspection done on paper. The firm has ten calendar days to send its firm-wide risk assessment, proliferation financing assessment, policies, template risk assessments and matter lists. The SRA then reads 10 to 12 files.

Eight-week rule

The time a law firm has to resolve a complaint before the client can take it to the Legal Ombudsman: eight weeks from the day the complaint is received. A complaint received on 1 October 2026 must be resolved by 26 November 2026.

Estate accounts

The record of an estate's administration, set out as three statements: capital, income and distribution. They are right only if total receipts equal total payments. No form is prescribed, but the court can require an inventory and an account.

Extended policy period

The 30 days of cover a firm's insurer must give after a professional indemnity policy expires with no replacement. A 60-day cessation period follows, in which the firm can take no new instructions. A policy that expired on 30 September 2026 runs out of both on 29 December.

Final response

The firm's written answer that closes its complaints procedure. It starts the client's six months to go to the Legal Ombudsman, but only if it states the six-month limit and gives the Ombudsman's full contact details. If it does not, that clock does not start.

Practising certificate fee

The yearly fee each solicitor's certificate costs. For 2026/27 it is £552: a £382 fee plus a £170 compensation fund contribution, against £396 the year before. The firm also pays a periodic fee set by its turnover band. Renewal runs from 1 to 31 October 2026.

Residual client balance

Client money left on a matter after it has finished that the firm cannot return. A balance of £500 or less can be paid to a charity without asking the SRA, provided the firm took reasonable steps to return it, recorded them and entered the payment in a central register. Over £500 needs the SRA's written authority.

Source of funds

Where the money for a transaction comes from. The Money Laundering Regulations require it to be scrutinised "where necessary", and the SRA expects a written reason when no check is done. In 2024 to 2025 the SRA found no check on 648 of 5,026 files that needed one.

Transparency Rules

The SRA rules that make firms publish prices for named services: six for individuals and three for businesses. For each, the page must carry seven items, including the total cost or range, disbursements, VAT, key stages and who does the work and their experience.
