Certificate Of Incumbency: What It Is, When You Need It And How To Get One

If you’re running a small business, it’s normal to assume that your Companies House filings, bank statements and signed contracts should be enough to show who has authority to act for your company.

But when you start dealing with banks, investors, overseas counterparties, big customers, or cross-border transactions, you may be asked for something more formal: a certificate of incumbency.

This document can feel a bit “corporate” (and it’s not something most UK SMEs need every day), but it’s essentially about one thing: showing who the current decision-makers are and who can sign on your company’s behalf.

Below, we break down what a certificate of incumbency is, when you’re likely to need one, what it typically includes, how to get it in the UK, and what to watch out for so you don’t lose momentum on an important deal.

What Is A Certificate Of Incumbency?

A certificate of incumbency is a formal document (usually prepared by the company and/or its advisers) confirming certain key people “currently in office” for a company (the incumbents) and, in many cases, their authority to act or sign documents for the business. It’s not an official Companies House document, and what it needs to cover will depend on what the requesting party is trying to verify.

In practice, it’s commonly used to verify:

• Who the company’s directors are (and sometimes which directors have specific signing authority)
• Who the company secretary is (if applicable)
• Who the shareholders are (sometimes requested, depending on the transaction)
• That the company is incorporated (typically by referring to supporting evidence such as the certificate of incorporation)
• That certain resolutions have been passed authorising a transaction (where relevant)
• Specimen signatures of the relevant office-holders (often attached)

Think of it as a “snapshot” of your company’s leadership and authority structure at a point in time, put into a format that third parties can rely on.

It’s especially common for international transactions, where the other party may not be familiar with UK Companies House records or may require a document that’s certified in a particular way.

Is A Certificate Of Incumbency A UK Legal Requirement?

Usually, no. In the UK, there isn’t a single universal “certificate of incumbency” prescribed by law for all businesses.

Instead, it tends to be a commercial requirement imposed by:

• banks and financial institutions
• investors or funders
• overseas counterparties
• professional advisers (for example, during transactions or corporate restructuring)

So even though it’s not something you “must” have in general, you may still effectively need one to get a deal done.

When Do Small Businesses Usually Need A Certificate Of Incumbency?

Most UK SMEs won’t be asked for a certificate of incumbency in day-to-day operations. But when you cross certain thresholds (bigger money, bigger risk, cross-border relationships), verification requirements get stricter.

Here are common scenarios where a certificate of incumbency comes up.

1) Opening Or Operating A Corporate Bank Account (Especially With Extra KYC Checks)

Banks must comply with strict anti-money laundering (AML) and “know your customer” (KYC) rules. If your company’s structure is complex, recently changed, or involves overseas elements, you may be asked to provide a document that clearly confirms who has authority to operate the account.

In those cases, a certificate of incumbency can be used as part of the verification pack.

2) Cross-Border Deals And Overseas Counterparties

If you’re signing a contract with a party outside the UK, they might not be comfortable relying on Companies House screenshots or informal confirmations.

For example, they might need a certificate of incumbency to confirm that:

• your company has properly authorised the agreement
• the person signing has the authority to do so
• the company is validly incorporated and currently active

3) Raising Investment Or Taking On A Loan

During investment rounds or financing, funders may request a certificate of incumbency (or equivalent) as part of their conditions precedent.

This is particularly common where there are multiple founders, different share classes, or any question about decision-making rights. If you’ve got (or plan to put in place) a Shareholders Agreement, that can help clarify governance and signing permissions, but it won’t always replace a certificate of incumbency where a lender wants a formal confirmation document.

4) Entering Into High-Value Contracts Where Signing Authority Is Sensitive

If the contract value is significant, the other party may want extra certainty that the agreement will be enforceable and properly authorised by your business.

This comes up a lot when the other party is a larger organisation with formal procurement and compliance processes.

5) Corporate Transactions And “Proof Of Authority” Requirements

If you’re involved in a business sale, acquisition, restructuring, or setting up a new subsidiary, you may be asked for an incumbency certificate as part of the transaction documents.

Even if you’re a small business, these transactions often have “big business” paperwork expectations.

What Does A Certificate Of Incumbency Usually Include?

There isn’t one single standard format for a certificate of incumbency, but a solid certificate typically includes enough information to let a third party comfortably rely on it (and it may be tailored to the specific transaction).

Common inclusions are:

• Company details (registered name, company number, registered office)
• Confirmation of incorporation (and sometimes jurisdiction), often supported by the company’s certificate of incorporation
• List of current directors (full names, roles)
• Company secretary details (if you have one)
• Confirmation of authorised signatories (who can sign and in what capacity)
• Specimen signatures for directors/signatories (if requested)
• Confirmation that the information is accurate as at a stated date
• Certification by an authorised person (and sometimes by a lawyer or notary, depending on what’s required)

Does It Need To Mention Shareholders?

Sometimes. Many certificates of incumbency focus on office-holders (directors/secretary) rather than shareholders. But in certain transactions, the other side might want confirmation of:

• major shareholders (especially controllers)
• the share structure
• who has voting control

This is particularly relevant if the deal requires shareholder approval under your governing documents.

How Does It Relate To Your Company’s Constitution?

Authority to act for a company is usually governed by a combination of:

• your company’s constitution (typically your Articles of Association)
• board and/or shareholder resolutions
• any internal delegations of authority (formal or informal)
• the general law and Companies Act framework

A certificate of incumbency often sits “on top” of these documents as a practical confirmation to outsiders that the right people are in place and properly authorised.

How Do You Get A Certificate Of Incumbency In The UK?

If you’ve been asked for a certificate of incumbency, the first step is to clarify exactly what the other party needs. Requirements can vary widely depending on the bank, jurisdiction, and the risk level of the transaction.

Once you know what’s required, there are a few common routes.

1) Prepare An Internal Certificate (If The Counterparty Will Accept It)

In some cases, you can prepare a certificate of incumbency internally, signed by a director or company secretary, confirming the current office-holders and signing authority.

This can work where:

• the transaction is relatively low risk
• the counterparty is UK-based and pragmatic
• there’s no requirement for notarisation or legalisation

But be careful here: if the other party has requested certification by a solicitor or notary, an internal certificate may be rejected and you’ll lose time.

2) Pass A Board Resolution And Issue A Formal Officer Certificate

Often, the certificate of incumbency is backed up by a board resolution that:

• confirms who the directors are
• authorises a specific transaction
• appoints named signatories

If your deal requires it, you may also need a shareholder resolution depending on what your Articles say and what the transaction involves. A properly documented Company Resolution is one of the cleanest ways to show authorisation and avoid disputes later about whether the company actually approved the deal.

3) Have A Solicitor Prepare And Certify It

For higher-stakes deals, the safest approach is usually to have a solicitor draft (or at least review and certify) the certificate of incumbency.

This is particularly useful where you need:

• a certificate that matches a strict template provided by the other party
• comfort that the signing authority is correct under your Articles and resolutions
• supporting transaction documents executed properly

This step is also helpful if the transaction involves signing formal documents as deeds. Execution rules can be technical, and getting it wrong can create enforceability issues. If you’re dealing with deed execution, it’s worth being across the basics of Executing Contracts so your paperwork doesn’t get held up.

4) Notarisation And Legalisation (Where The Document Is Going Overseas)

If the certificate is being used abroad, the receiving jurisdiction might require notarisation, and sometimes “legalisation” (often via an apostille process).

This is common when:

• you’re opening an overseas bank account
• you’re establishing operations in another country
• you’re entering into a cross-border financing arrangement

Not every overseas party will require this level of formality, but if they do, it’s best to factor in additional time.

What Should You Check Before You Provide A Certificate Of Incumbency?

A certificate of incumbency is only helpful if it’s accurate and consistent with your company’s records. If there are discrepancies, it can trigger extra due diligence questions, delays, or even raise concerns about governance.

Before you send one out, it’s worth doing a quick “authority audit” so you don’t accidentally create problems.

Are Your Companies House Details Up To Date?

If you’ve recently appointed or removed a director, make sure filings are up to date. Counterparties often cross-check incumbency certificates against public records.

If you’re not sure who is currently listed (or you want to check another company you’re dealing with), it’s straightforward to confirm using Company Director Search.

Do You Have Clear Signing Authority Internally?

Small businesses often operate on trust (which is great), but a deal can expose gaps like:

• two founders disagreeing on whether someone can sign
• a director assuming they have authority when the Articles restrict it
• staff signing documents without the right delegation

If you routinely need someone to sign for the business (for example, an operations lead or finance manager), you may need to formalise the arrangement. Having a clear understanding of Signing Authority can prevent confusion and reduce the risk of deals being challenged later.

Are You Signing A Deed Or A Standard Contract?

Why does this matter? Because the signing formalities can differ. Deeds often require stricter execution steps than a standard contract, and third parties may request a certificate of incumbency specifically because they want confidence the document will be executed correctly.

If the document needs a witness, make sure the witness is appropriate and independent. The rules aren’t always intuitive, so it’s worth checking Witness Requirements before anyone signs.

Does The Certificate Disclose Personal Data?

A certificate of incumbency usually includes names and sometimes signatures. That can involve personal data.

In most business contexts, sharing this information is legitimate and expected, but you should still treat it carefully, especially if you’re sending it across borders or via insecure channels.

As a practical step:

• only share the information necessary for the purpose
• send it securely (especially if it includes specimen signatures)
• keep a record of what you sent and to whom

Common Alternatives (And Why They Might Not Be Enough)

If you’ve been asked for a certificate of incumbency, you might wonder whether you can just send another document instead.

Sometimes you can, but it depends on what the other side is trying to prove.

Companies House Records

Companies House records can confirm directors and registered office details, but they may not:

• confirm signing authority for a specific transaction
• show internal delegations
• include specimen signatures

Certificate Of Incorporation

This proves the company exists, but it doesn’t confirm who currently holds office or who can sign today.

Board Minutes / Resolutions

Resolutions are excellent for proving authorisation, but the counterparty may still want an “incumbency snapshot” confirming who is currently in office and that the signatories are the right people.

Power Of Attorney

A power of attorney can be used to delegate authority to sign, but it’s not always appropriate and it can add complexity. The simplest path is often a clean resolution plus a certificate of incumbency that reflects your actual governance structure.

Key Takeaways

• A certificate of incumbency is a formal document used to confirm your company’s current office-holders (like directors) and, often, who has authority to sign on behalf of the business.
• In the UK, it’s usually not a general legal requirement, but you may need one to satisfy banks, investors, or overseas counterparties.
• You’re most likely to need a certificate of incumbency for cross-border transactions, financing/investment, higher-value contracts, or situations where signing authority must be clearly proven.
• There’s no single “one-size-fits-all” format, so always check what the requesting party needs (including whether notarisation or legalisation is required).
• Before issuing one, make sure your Companies House records, internal authority, and execution formalities (especially for deeds and witnesses) are consistent and correct.
• If the document will be relied on for a major deal, it’s usually worth having a lawyer help draft or review it so you don’t risk delays or enforceability issues.
