A serious buyer needs to understand your practice before making an offer. That can mean discussing recurring fees, staff responsibilities, pricing and client relationships. Sharing those details without clear boundaries can leave your business exposed, particularly when the buyer also operates in your market.
Non-disclosure agreements when selling an accounting practice help establish how a prospective buyer may use sensitive information. They are an important part of preparation, but they work best alongside careful screening and controlled disclosure.
This guide explains the decisions to make before signing, the terms worth reviewing and the practical steps that keep information sharing organised. Your solicitor should tailor the agreement to the transaction and relevant UK jurisdiction.
Agree confidentiality before detailed talks
An NDA, also called a confidentiality agreement, creates contractual obligations around specified information. It should make clear that the buyer receives it to evaluate a proposed acquisition, rather than for unrestricted commercial use.
Arrange the agreement before sending sensitive documents or holding detailed discussions. A general overview may be enough to establish initial interest, provided it does not identify clients or reveal confidential details indirectly.
For example, a broad fee range may help a buyer decide whether the opportunity fits. A list of named clients and their individual charges goes much further. Signing an NDA does not automatically make that second disclosure appropriate.
Check who is signing
Confirm the buyer’s legal identity, including the company name rather than just a trading name. Identify the correct seller too, particularly where different entities hold the practice’s information.
Check that the signatory has authority to bind the recipient. If an acquisition vehicle is proposed, ask who will actually receive documents and whether other group companies need obligations of their own.
A one-way agreement generally suits information flowing from seller to buyer. Where both parties disclose sensitive information, mutual protection may be appropriate. Ask your solicitor to check execution requirements; a one-way NDA may need to be executed as a deed. Avoid turning it into an artificial mutual agreement simply to sidestep that question.
Define the information and its use
Specify the categories needing protection, such as financial reports, fee analyses, operational processes and information about the proposed sale itself. Consider discussions, presentations and notes derived from your documents as well as the documents themselves.
The permitted purpose should fit the actual transaction. Wording that allows broad business use could undermine the protection you expect. Agree how additional disclosures will be treated if negotiations expand into a merger or another arrangement.
Review the exclusions as carefully as the protection. Information already lawfully known to the buyer, independently developed or genuinely public may fall outside confidentiality obligations. Disclosure required by law needs separate handling, including notice where lawful and appropriate. These exceptions should not become an excuse for sharing the entire pack more widely.
Use the following points as a review agenda for your solicitor, rather than ready-made contractual clauses.
| Review point | Decision to agree |
| Protected information | Documents, discussions and derived material |
| Permitted use | Evaluation of the proposed transaction |
| Onward disclosure | Authorised recipients and their obligations |
| Exceptions | Existing knowledge and lawful disclosure |
| End of talks | Continuing duties and return or deletion |

Control advisers and buyer contact
A buyer may need its solicitor, accountant or lender to review information. Identify permitted recipients, limit access to those who need it and agree how their confidentiality obligations will be addressed. Clarify responsibility if a representative misuses documents.
Discuss whether the buyer may approach clients, employees or suppliers during negotiations. A confidentiality clause and a non-solicitation restriction address different behaviour; one should not be assumed to include the other.
Restrictions need careful drafting, including their scope, duration and any existing relationships or ordinary recruitment exceptions. A blanket ban is not automatically enforceable. Make your practical preference clear: questions should come through an agreed contact until introductions are authorised.
Keep client duties separate
Your clients’ confidential information is not yours to disclose freely. ICAEW guidance on practice sales says client authority would usually be required before disclosure of client confidential information. Review the applicable professional rules and engagement terms before providing access.
Where personal data is involved, assess the lawful basis, necessity, security and transparency requirements separately. An NDA does not supply a UK GDPR lawful basis or replace those responsibilities. The ICO specifically addresses data sharing during acquisitions.
Our guide to client confidentiality explains the broader considerations. If the legal position is uncertain, pause the proposed disclosure and seek advice rather than relying on the signature alone.
Make disclosure easy to track
Translate the agreed terms into a workable process. Use named accounts in a secure data room, restrict permissions and avoid sending entire folders when a summary will answer the buyer’s question.
Create a simple disclosure log recording the document version, recipient, date and reason for sharing. Keep written notes of significant verbal disclosures too. Remove irrelevant identifiers from sample records and check spreadsheets for hidden tabs or comments before release.
Our due diligence checklist can help organise the wider preparation. For a competing buyer, ask your advisers whether especially sensitive details should initially be reviewed by a smaller authorised team.
Nominate one person to approve releases. If two partners answer buyer questions separately, they may share inconsistent figures or disclose more together than either intended. A single route for requests makes it easier to maintain accurate records without slowing every conversation.
Plan for expiry and failed talks
Agree how long confidentiality obligations continue and whether different information needs different treatment. Do not assume every obligation disappears when negotiations stop. Equally, avoid an unexplained permanent restriction covering every item regardless of sensitivity.
Set out return or deletion arrangements, including copies and analyses. Consider justified retention for legal or regulatory obligations and how inaccessible backups will be handled. Retained information should remain subject to appropriate restrictions.
If talks end, close data-room access promptly and request the agreed confirmation of compliance. If the sale completes, have your solicitor align the NDA with the sale agreement so responsibilities remain clear.
Organise your due diligence pack
Our team can help you prepare the commercial information for buyer discussions while your advisers assess confidentiality and disclosure requirements.
Respond promptly to suspected misuse
If information appears to have been shared or used improperly, preserve correspondence and access records, restrict further disclosure and contact your solicitor. Establish what happened before making accusations or circulating the issue more widely.
Depending on the facts and jurisdiction, legal remedies may include damages or urgent court relief. Neither is guaranteed, and recovering compensation cannot always repair lost trust. A personal data incident also needs a separate breach assessment.
Sell Practice can help organise buyer enquiries and commercial preparation alongside your legal advisers. Addressing confidentiality early makes the wider legal requirements easier to coordinate as negotiations progress.
