Pre‑Completion, Completion and Post‑Completion: The Final Stages When Buying or Selling a Business
The final stages of buying or selling a business are divided into pre-completion, completion, and post-completion. Pre-completion focuses on preparation and conditions, completion is when ownership transfers and funds are paid, and post-completion ensures legal filings and obligations are finalised.
Understanding the Final Stages of Buying or Selling a Business
Buying or selling a business is a significant legal and commercial transaction. Once the main terms are agreed and the key documents are negotiated, the process moves into its final stages. These are typically divided into three phases: pre-completion, completion, and post-completion.
Together, each phase ensures that ownership transfers correctly, risks are managed, and all legal and regulatory requirements are met. Whether you are buying / selling shares in a company or acquiring / selling business assets, understanding these stages will help you prepare and avoid unnecessary delays.
Pre-Completion
The pre-completion stage focuses on preparation for completion. At this point, the deal is largely agreed in principle, but several important steps must be completed before the transaction can formally proceed and complete.
During this phase, your legal team will finalise due diligence, prepare transaction documents, and ensure that all conditions for completion are satisfied.
Financial matters
Financial arrangements are reviewed and documented to ensure both parties are aligned before completion takes place.
A completion statement is prepared setting out the financial position of the transaction so that each party explicitly understands the monies they will pay or receive at the time of completion. This typically includes:
- the purchase price;
- any adjustments;
- professional fees (such as undertakings to third parties which are deducted at source); and
- apportionments such as rent or service charges.
The completion statement ensures transparency and avoids disputes at completion.
If a deposit is required, this will be requested and held securely by the relevant solicitor (typically the seller’s solicitors). Buyers must ensure funds are available in cleared form ahead of completion, while sellers will receive confirmation of the amounts due to them.
Risk assessment and compliance
Legal and regulatory checks are essential to protect all parties and ensure compliance with the law.
Solicitors are required to carry out Anti-Money Laundering checks and will specifically seek to confirm source of funds. This typically includes buyers providing evidence of the source of funds (such as bank statements), which can take time to verify. Delays at this stage are common if information is incomplete or unclear.
Both parties will be asked to confirm they are ready, willing, and able to complete. This is a key step, as it ensures there are no outstanding issues that could prevent completion.
Document preparation and signing
Transaction documents must be carefully reviewed and executed correctly.
Your legal team will provide clear instructions on how and where to sign documents. It is important to follow these precisely, as incorrectly signed documents can delay completion or require re-execution. Most solicitors utilise electronic signing for documents, however, it is important to note that sometimes you will be required to sign documents by hand (i.e., where the documents need to be submitted to the Land Registry).
Promptly reviewing documents and raising any queries early helps prevent last-minute issues. This is particularly important where multiple parties are involved and where approval from a third party is required (such as a landlord). These may include landlord consent for leasehold premises, lender consent, shareholder approvals, or HMRC clearance in certain cases. Completion cannot take place until all required consents are obtained.
Where external finance is involved, additional steps must be coordinated.
For example, lenders typically require pre-completion documentation, title reports, and confirmation of completion arrangements. Funds are then scheduled for release in line with the agreed completion date. It is important to ensure that the lender’s solicitors are provided timely updates and given enough time to review any agreed documents they require sight of, as they will need to provide a report to the lender before signing off on the lending element.
Completion
Completion is the point at which the transaction legally takes effect. Ownership transfers, documents are released, and funds are paid.
This stage is often fast-moving and requires close coordination between all parties as final versions of agreements, including schedules and annexes, are checked to ensure accuracy.
On the day of completion and where a disclosure letter is being entered into, the buyer’s solicitors will be required to carry out certain searches (against the company and/or the company’s property, such as Land Registry searches or intellectual property office searches).
A completion call may take place between the parties and their advisers. The call confirms that all conditions have been satisfied, documents are in place, and parties are ready to proceed.
The completion funds are usually transferred to the relevant solicitor ahead of the completion call and are held to the order (i.e., the recipient solicitor cannot release the funds to their client until the transferring solicitor gives them authority to do so).
Once completion has taken place, parties should refer to the transaction documents as they set out specific obligations that must be satisfied at completion (for example, the delivery of certain documents such as company records or contracts).
Post-Completion
Although completion marks the legal transfer of ownership, several important steps remain. These ensure the transaction is properly recorded and fully effective in law.
There are strict deadlines for certain post-completion actions. For example:
- Where applicable, Stamp Duty Land Tax must be submitted and paid within the required timeframe. Property transactions must also be registered at the Land Registry.
- Notices may need to be served on landlords, and any charges or security interests must be registered.
- Corporate records (this may include issuing or cancelling share certificates and updating statutory registers) will need to be updated and filings will need to be carried out at Companies House (usually filings that update the directors and PSCs).
All completion documents are circulated to the relevant parties. Company records are updated, and any undertakings given during the transaction are discharged.
How You Can Help Ensure a Smooth Transaction
Your cooperation plays an important role in keeping the transaction on track.
You should:
- supply requested documents, identification, and financial information without delay to avoid bottlenecks. Many delays in transactions arise simply from missing or incomplete information.
- take time to review documents properly, while also responding promptly, to ensure you position is protected or as you understand it.
- (for a buyer) ensure funds are available in cleared form ahead of completion. It is also important to notify your bank in advance if large transfers are expected, as this can prevent last-minute issues.
- stay in regular contact with your legal team and respond quickly to queries to significantly reduce the risk of delays, particularly in the final stages.
Conclusion
The final stages of buying or selling a business are structured but often fast-paced. Pre-completion focuses on preparation and risk management, completion formalises the transfer of ownership, and post-completion ensures all legal and regulatory requirements are satisfied.
A successful transaction depends on careful planning, attention to detail, and clear communication throughout. By understanding what to expect at each stage and working closely with your legal advisers, you can help ensure the process runs smoothly and efficiently.
