A share certificate can make a company purchase look deceptively simple. It identifies shares, a holder and, usually, a class of ownership. It does not tell a buyer whether the company owes tax, has pledged its machinery to a bank, is defending an employee claim, has lost a licence, or is operating through a shareholder whose real controller is somebody else. That is why buying shares is legally different from buying selected assets. The company itself continues after the transaction, and its history normally continues with it.

For a foreign investor, this matters even more. A local partner may know the business, the market and the people around it, but familiarity is not a substitute for verification. The useful question before buying shares in Kenya, Uganda, Rwanda or mainland Tanzania is not merely, “Does the seller own these shares?” It is also, “What obligations, restrictions and disputes will remain inside the company after I become an owner?” A disciplined due diligence review answers that second question before the purchase price is released.

Start with the company, not the certificate

The first task is to confirm that the company legally exists, that its registered details match the transaction documents, and that the seller is entitled to transfer the shares offered. The buyer should obtain the current incorporation record, constitutional documents, register of members, recent annual filings, director details, share allotment history and any restrictions on transfer. Minutes and shareholder resolutions should then be checked for earlier allotments, options, pre-emption rights, pledges or agreements that could interfere with the sale.

In Kenya, the Companies Act, Cap. 486, treats entry in the register of members as central to membership, while the Business Registration Service offers an official company search commonly known as a CR12. The current Companies Act is published by Kenya Law as legislation at 27 December 2024. In Uganda, the Companies Act, as consolidated to 31 December 2023, permits inspection of documents kept by the Registrar on payment of the prescribed fee. Rwanda’s company framework is governed by Law No. 007/2021, and the Office of the Registrar General handles post-registration company changes. In mainland Tanzania, BRELA currently publishes the Companies Act, Revised Edition 2023, together with 2026 company forms. These registry records should be compared with the company’s own internal registers rather than accepted in isolation.

A mismatch is not always fraud. It may be an unfiled update, an administrative delay or poor company secretarial practice. But the buyer should not complete until the discrepancy is explained and, where necessary, corrected. Ownership that cannot be demonstrated cleanly before completion will usually be harder to fix after the money has changed hands.

Tax clearance is a screening tool, not the whole tax review

Tax is one of the easiest liabilities to underestimate because a company may appear profitable while carrying undeclared or disputed obligations from earlier periods. The review should cover corporate income tax, VAT where applicable, payroll taxes, withholding taxes, customs exposure, property-related taxes, tax audits, objections, payment plans and correspondence with the revenue authority. Reconcile filed returns with audited or management accounts and bank records. A tax figure in the financial statements is only useful if it can be traced to the underlying filings and payments.

Official tax-clearance documents are helpful but should not be treated as an absolute warranty that no historic exposure exists. The Kenya Revenue Authority states that a Tax Compliance Certificate confirms filing and payment compliance and is valid for twelve months. Uganda Revenue Authority describes its Tax Clearance Certificate as confirming that tax affairs are in order at the date of issue. Rwanda Revenue Authority states that its Tax Clearance Certificate confirms that the taxpayer has met tax obligations and currently gives it three months’ validity. In Tanzania, the Tanzania Investment Centre’s current business-licensing guidance includes tax clearance among the documents required for a business licence.

A prudent share buyer should therefore request the current certificate where available, but also ask whether any audit, investigation, objection, customs review or unpaid assessment is pending. The sale agreement can then deal specifically with pre-completion tax through warranties and, where the risk is material, a separate tax indemnity.

Find the debt and then find the security behind it

A loan schedule should show more than the outstanding balance. It should identify the lender, facility limit, repayment terms, guarantees, events of default and every asset given as security. Bank statements should be checked for undisclosed facilities, repeated overdrafts, unusual related-party payments and repayments to shareholders or directors. Ask separately about shareholder loans, supplier finance, hire purchase, finance leases and guarantees given for another person’s debt.

The next question is whether the company’s assets are charged. Kenya’s Business Registration Service registers debentures and charges and issues records relating to them. Uganda’s Companies Act requires registration of specified company charges, including charges over immovable property, book debts, floating charges and certain intellectual-property rights; Uganda also operates the Security Interest in Movable Property Registry, which permits searches by grantor name. Rwanda’s Office of the Registrar General provides a public search mechanism for registered security interests in movable property. In Tanzania, BRELA’s current 2026 company forms include Form 99 for particulars of a mortgage or charge.

Registry searches should be matched against the company’s loan agreements and asset records. A clean company search does not justify assuming that every asset is unencumbered. Land, vehicles, intellectual property and other assets may require separate searches in the relevant registry. The buyer should also identify any lender consent needed because a change in shareholding can itself trigger a contractual default.

Employees create obligations that do not disappear on a share sale

Because the employer company normally remains the same legal person after its shares change hands, the buyer should investigate the employment obligations already sitting in that company. Review employment contracts, payroll, leave records, commissions, bonuses, pension or social-security contributions, disciplinary matters, collective arrangements, expatriate permits, termination claims and any promises made outside written contracts. Compare the employee list with payroll and bank payments; unexplained names, cash payments or long-serving “consultants” can point to liabilities that the formal staff list does not reveal.

The governing labour law must be current. Kenya Law identifies the Employment Act, Cap. 226, in its version of 26 April 2024 as the latest version. Uganda’s Employment Act was amended by the Employment (Amendment) Act 2026, effective 5 June 2026, so older checklists may miss current requirements. Rwanda continues to operate under Law No. 66/2018 regulating labour, alongside implementing measures. For mainland Tanzania, the Office of the Solicitor General publishes the Employment and Labour Relations Act, Chapter 366, Revised Edition 2023.

The practical objective is not to re-audit every employment decision ever made. It is to understand what the company may already owe and whether a serious dispute, underpayment pattern or compliance failure could become the new shareholder’s economic problem after completion.

Litigation includes the disputes that have not reached court

A litigation search is necessary, but it is not enough to search only reported judgments. Ask the company for a signed schedule of current and threatened court cases, arbitrations, labour disputes, tax objections, regulator investigations, demand letters, debt-collection matters and settlement agreements. Review correspondence from advocates and insurers, and check whether any judgment or order remains unsatisfied.

Independent court and tribunal searches should be carried out where public systems permit, but absence from a searchable database should never be treated as proof that no dispute exists. Some matters are newly filed, confidential, unreported, arbitrated, settled privately or still at the demand-letter stage. The buyer should therefore compare external searches with board minutes, legal-expense accounts, auditor correspondence and management representations. If management says a claim is “not serious,” ask what amount is claimed, what the lawyer has advised, whether insurance responds and what happens if the company loses.

A licence can be valuable and still be fragile

For a regulated business, the most valuable asset may be permission to operate. The buyer should obtain every material business and sector licence, note its holder, expiry date, conditions and renewal history, and confirm whether the acquisition itself requires notification or prior consent. Check inspection reports, warning letters, penalties, licence suspensions and undertakings given to a regulator. A company that is trading while a key approval has expired may have far less value than its revenue suggests.

The rules are sector specific. Tanzania’s current investment guidance, for example, requires sectoral approval for businesses regulated by specific laws. Rwanda’s financial-sector rules provide a useful warning about change-of-control risk: Regulation No. 46/2022 specifically governs changes in shareholding of insurers and reinsurers. Comparable approval requirements may arise under banking, insurance, telecommunications, mining, energy, health, education or other regulated-sector laws in the other jurisdictions. The safe approach is therefore to check the company’s actual sector regulator, not to assume that Companies Act compliance alone makes a share transfer effective for regulatory purposes.

Identify who really owns and controls the company

Beneficial ownership due diligence is not a formality. It helps the buyer identify the natural persons who ultimately own or control the company, detect nominee arrangements, understand voting influence and test whether the disclosed ownership structure matches the commercial reality. The buyer should reconcile the register of members, beneficial-ownership filings, shareholder agreements, voting arrangements and any trust, nominee or holding-company structure.

Kenya’s current Beneficial Ownership Information Regulations treat a natural person as a beneficial owner where, among other tests, the person directly or indirectly holds at least ten percent of issued shares or voting rights, has a right to appoint or remove a director, or exercises significant influence or control. Uganda’s Companies Act requires companies with beneficial owners to keep a beneficial-owner register and provides for the Registrar to maintain and verify such information. Rwanda’s Office of the Registrar General requires beneficial-owner information and supporting evidence that may include a share certificate, articles of association or shareholder agreement. Tanzania’s current BRELA forms expressly include declarations for a registered shareholder who does not hold the beneficial interest and for a beneficial owner whose name is not in the register of members.

This exercise should also be connected to sanctions, anti-money-laundering and reputational checks appropriate to the transaction. The purpose is not to treat a complex ownership chain as suspicious by itself. It is to know who is behind the investment before the buyer becomes legally and commercially tied to it.

Make the due diligence findings change the sale agreement

Due diligence has little value if every problem is discovered and then ignored in the contract. Findings should determine whether the buyer proceeds, changes the price, requires a problem to be fixed before completion, retains part of the price, seeks an escrow arrangement or walks away. Material lender consents, regulator approvals, tax clearances, release of security, settlement of a serious claim or correction of the shareholder register can be made conditions that must be satisfied before completion.

The sale agreement should then allocate the remaining risk. Warranties can require the seller to confirm the accuracy of information about tax, litigation, employees, borrowing, licences, beneficial ownership and regulatory compliance. A disclosure letter should identify the exceptions with enough detail for the buyer to understand them. Specific indemnities are often more useful than broad warranties where a known problem already exists, such as an identified tax audit, employee claim or environmental penalty. Time limits, financial caps and procedures for bringing claims should be negotiated consciously rather than copied from a precedent.

Finally, completion should be treated as a controlled legal event. Confirm that transfer documents, board or shareholder approvals, resignations or appointments, register updates, regulatory consents and payment mechanics are ready together. Do not release the full price merely because the parties have signed the main agreement if the conditions that protect the buyer have not actually been satisfied.

The best due diligence question is: what survives completion?

A foreign investor does not need to approach every East African company as though something is wrong. The point of due diligence is the opposite: it separates ordinary business risk from a liability that can be verified, priced, corrected or contractually allocated. A profitable company with a disclosed bank loan is different from a profitable company whose main assets are secretly pledged. A company defending one manageable employment claim is different from one with a systemic payroll problem. A licence due for routine renewal is different from one threatened with cancellation.

The share certificate is therefore only the beginning of the legal inquiry. Before buying shares in Kenya, Uganda, Rwanda or mainland Tanzania, the investor should build a transaction file that explains who owns the company, what it owes, what it has promised, what assets are secured, which employees may have claims, what regulators expect and which disputes may still mature into liabilities. When those answers are documented before completion, the buyer is in a much stronger position to decide whether the shares are worth the price being asked.
