Company Execution Clause In The UK

If you’re sending out contracts to customers, suppliers or investors, the execution clause is the small section that can make or break enforceability. It tells everyone how the company will validly sign the document, who must sign, and whether a witness is required.

Get this wrong, and you risk arguments that your agreement isn’t binding or your deed isn’t properly executed. The good news? With a clear company execution clause and the right signing process, you can lock in certainty and protect your deals from day one.

In this guide, we break down what a company execution clause is, when you need it, and how to draft and use it correctly under UK law (especially the Companies Act 2006).

What Is A Company Execution Clause?

A company execution clause is the part of a contract or deed that sets out how the company signs the document so it’s legally valid. It typically appears at the end of the document in the signature blocks and uses wording that aligns with the Companies Act 2006. The clause often covers:

• Who can sign (for example, two “authorised signatories” or a sole director with a witness).
• Whether the document is a simple contract or a deed (the rules are different).
• Any witnessing requirements (including the witness’s details and attestation wording).
• Practical mechanics such as counterparts and e-signatures.

Why it matters: the execution method is not just admin. It’s the legal mechanism that makes your contract or deed binding on the company. If your execution clause doesn’t match what the law requires, you could face delays, disputes, or the risk that a deed isn’t enforceable.

For a deeper dive into the mechanics, it helps to understand the difference between a simple agreement and a deed, as deeds have stricter formalities than contracts. If you’re unsure which you need, it’s worth reading up on the difference between a deed and an agreement.

When Do UK Companies Need A Formal Execution Clause?

Almost every written contract benefits from a clear execution clause, but it’s essential when:

• The document is a deed (for example, a deed of assignment, a guarantee, or a settlement deed).
• You’re signing a high‑value or long‑term contract and want zero doubt about enforceability.
• There are multiple parties and signatures will be obtained in counterparts or electronically.
• A sole director is signing on behalf of a private company (to clarify that a witness will attest the signature).
• Your counterpart asks for specific execution wording to satisfy their internal policies or lenders.

In short, an execution clause removes ambiguity. It tells your team and your counterpart exactly how to get the deal “over the line” properly the first time. If your matter is time‑sensitive, a clean, compliant clause also prevents last‑minute back‑and‑forth about who can sign and how.

How Do Companies Validly Execute Under The Companies Act 2006?

The Companies Act 2006 provides different pathways for companies to sign documents. Here are the practical rules most SMEs use day to day.

Simple Contracts (Not Deeds)

For ordinary (non-deed) contracts, a company can contract through someone acting with authority on its behalf (Companies Act 2006, s.43). In practice:

• A director, officer or employee with actual or apparent authority can sign.
• You don’t need a witness for a simple contract (unless your counterpart insists).
• Authority can be granted by a board resolution or by position and conduct (apparent authority).

If you regularly let operational staff place orders or sign supplier forms, consider whether they have authority to bind the company. It’s a common risk area - our overview of an employee’s capacity to bind a company by contract explains how authority works in practice and how to reduce the risk of unintended commitments.

Executing “Documents” (Including Deeds)

For documents the company executes as a “document” under s.44 (which includes deeds), the common methods are:

• By two authorised signatories (typically two directors, or one director and the company secretary); or
• By a single director in the presence of a witness who attests the signature (the witness signs and provides their name, address and occupation).

Many private companies don’t have a company secretary. If you have only one director, use the single‑director plus witness method. This is the safest way to execute a deed without a second authorised signatory. For more practical detail (including model signature blocks), see our guide to executing contracts and deeds in England.

What Does “Authorised Signatory” Mean?

An “authorised signatory” under the Act is a director or the company secretary. For simple contracts, you can also rely on someone with authority (per s.43), but for s.44 execution as a document, stick to the authorised signatory routes above or a director with a witness.

What About Electronic Signatures?

Electronic signatures are generally valid in England and Wales, including for deeds, provided the formalities are met (such as witnessing in person for deeds). Many businesses use reputable e‑signature platforms with a “witnessing” feature. The critical point is that the witness must be physically present when the director e‑signs a deed, even if both apply their signatures electronically. Our practical tips in the execution guide cover Mercury‑style processes and common pitfalls.

Who Can Be A Witness?

A witness must be independent (ideally not a family member or party to the contract), over 18 and of sound mind. They must actually see the director sign, in person. If you’re unsure who qualifies, check our article on witnessing deeds or this overview of witnesses for contracts.

How To Draft A Robust Company Execution Clause

Your execution clause should make it easy for your signatories to follow the correct method, whether you’re signing a simple contract or a deed. Here’s what to cover.

1) State The Nature Of The Document

If your document is intended to be a deed, make that clear on the front page and in the execution clause. Deeds require specific wording (for example, “Executed as a deed by…” and a statement of delivery) and stricter formalities. If you’re weighing up whether you need a deed at all, this explainer on the difference between deed and agreement will help you decide.

2) Provide Clear Signature Blocks

Set out signature blocks that align with s.44:

• Option A – Two authorised signatories: “Executed by acting by , Director and , Director.”
• Option B – Sole director with witness: “Executed as a deed by acting by , Director, in the presence of: .”

Include the full company name and number, and printed names and titles beneath each signature line. This sounds basic, but missing titles can cause friction with counterparties and funders doing diligence.

3) Add Counterparts And E‑Signature Language (If Needed)

Where you expect remote signing, include a counterparts clause and make it clear that electronic signatures are acceptable. For deeds, ensure your process still satisfies witnessing requirements (physical presence). If your workflow includes email confirmations or click‑acceptance for lower‑risk deals, remember that sometimes emails can form binding contracts even without a formal signature - so it’s wise to say when a contract is intended to take effect.

4) Confirm Who Has Signing Authority

Internally, make sure your board has authorised the signatories. If someone is signing “for and on behalf of” the company (e.g., an operations manager), confirm their authority in writing. Our guide to signing authority explains how to document this cleanly so counterparties have confidence when they see your execution clause.

5) Keep Witness Details Complete

For deeds, ask the witness to print their full name, address and occupation beneath their signature. If a lender or buyer later reviews the document, complete witness details reduce the risk of questions about validity. If any party needs extra reassurance on formalities for deeds, point them to independent guidance or your own internal policy.

Common Pitfalls With Company Execution Clauses (And How To Avoid Them)

Here are the mistakes we see most often in SME contracts and what you can do instead.

Using The Wrong Method For A Deed

Problem: A sole director signs a deed without a witness. Fix: Use the “director in the presence of a witness” route, ensuring the witness is physically present and attests the signature in the block. If you need a refresher, revisit the core rules in our guide to executing contracts and deeds.

Assuming Any Employee Can Sign Anything

Problem: Staff sign supplier forms or sales contracts outside their authority, binding the company to unfavourable terms. Fix: Put a clear delegated authority policy in place and align your execution clause with that policy. As background, check how employees can (and can’t) bind a company.

Mixing Up Deeds And Agreements

Problem: Practicalities like consideration and limitation periods get overlooked because the document type isn’t thought through. Fix: Confirm early whether you need a deed (e.g., for guarantees or variations without fresh consideration). If you’re uncertain, compare the differences between deeds and agreements and get tailored advice.

Incomplete Witnessing

Problem: The witness didn’t actually see the director sign or their details are missing. Fix: Make “in‑person witnessing” a non‑negotiable step for deeds and capture full witness details. If your team needs guidance on who qualifies, refer them to the overview on witnessing deeds.

Relying On Email Threads When A Formal Contract Was Intended

Problem: A deal proceeds based on emails, then a dispute arises about terms because the execution clause in the draft contract was never used. Fix: Make it explicit when a formal contract will take effect, and ensure signatures are captured correctly. Remember, emails can sometimes be legally binding, but that may not reflect what you intended.

Unclear Authority Or Board Approval

Problem: A counterparty queries whether your signatory had authority, delaying completion. Fix: Keep a tidy paper trail - board minutes or a written delegation help. If something goes wrong and the document is left unsigned, consider where that leaves you - in some cases, an unsigned contract might still be enforceable, but don’t rely on that. It’s always better to execute properly.

Practical Execution Wording You Can Expect To See

While every document should be tailored, these examples show what compliant signature blocks typically look like under s.44:

Two Directors (or Director + Secretary) – Deed

Executed as a deed by (Company No. ) acting by:

....................................................... Director (print name)

....................................................... Director/Company Secretary (print name)

Sole Director With Witness – Deed

Executed as a deed by (Company No. ) acting by:

....................................................... , Director

In the presence of:

Witness signature: ....................................................

Name: ....................................................

Address: ....................................................

Occupation: ....................................................

Simple Contract (Not A Deed)

Signed for and on behalf of (Company No. ) by:

....................................................... , Director

Tip: Keep the job title under each signature. If you use “for and on behalf of,” make sure the signatory has authority consistent with your internal delegations.

Execution Logistics: E‑Signatures, Counterparts And Storage

To keep signatures moving without compromising validity, build these practices into your process and drafting:

• E‑signing: Use a platform that supports witnessing for deeds. Ensure the witness is physically present with the signatory at the time of e‑signing.
• Counterparts: Add a standard clause allowing the document to be signed in counterparts so each party can sign separately.
• Final form for execution: Follow “Mercury” principles - sign only the final, agreed form and circulate complete PDFs to all parties.
• Record‑keeping: Keep fully executed versions safely filed. If you ever need to enforce a deed or explain an execution method, clean records make life easier.
• Authority checks: Before signing, confirm signatories’ authority. If someone is signing under a power or specific delegation, keep the authorising document with your records.

If you ever need to assign rights under a contract later, you’ll thank yourself for a properly executed original - particularly where an assignment needs to be done by deed (for example, a deed of assignment).

Key Takeaways

• A company execution clause sets out how your company will validly sign a contract or deed - it’s the small section that protects enforceability.
• For simple contracts, a person with authority can sign for the company (s.43). For deeds or documents executed under s.44, use either two authorised signatories or a sole director with an in‑person witness attesting the signature.
• Electronic signatures are generally fine, but deeds still require in‑person witnessing. Use clear counterparts and e‑signature wording in your execution clause.
• Don’t mix up deeds and agreements - they have different formalities and effects. If in doubt, compare the deed vs agreement position and get advice.
• Avoid common pitfalls: missing witness details, incorrect signatory combinations, unclear authority, or relying on informal email threads when you intended a formal contract.
• Set up internal delegations and keep board approvals handy so counterparties are comfortable that your signatories have authority. For tricky scenarios, review signing authority and capacity to bind.
