Explore the legal risks of acting before company incorporation in England and Wales, including personal liability for pre‑incorporation contracts under section 51 of the Companies Act 2006, statutory and case law principles, novation and avoidance strategies, and practical guidance for promoters and founders.
When planning a business in England and Wales, founders sometimes act in advance of formally incorporating a company. This can include entering into contracts, hiring premises, buying equipment, or negotiating with suppliers before the company legally exists. While commercial urgency might make such actions seem practical, they expose individuals involved to significant legal and financial risks because, until incorporation is completed at Companies House, the intended company has no legal personality, and therefore cannot contract or incur obligations in its own right.
This article explains what the law says about acting before incorporation, the risks involved in pre‑incorporation activities, how liabilities may arise, the concept of pre‑incorporation contracts, steps for managing risks, and answers to common questions for those contemplating pre‑formation actions.
Legal Personality and Pre‑Incorporation Activities
A company only comes into legal existence once it has been validly registered and issued a certificate of incorporation by Companies House. Prior to that moment, the company does not possess legal personality and cannot be a party to contracts, own property, sue or be sued. This means that individuals who purport to act “on behalf” of an unformed company risk personal liability for any obligations they assume in that capacity. The relevant statutory rule is section 51 of the Companies Act 2006, which applies to contracts, deeds and other obligations purportedly made on behalf of a company before formation.
Pre‑incorporation Contracts: Law and Liability
What Is a Pre‑Incorporation Contract?
A pre‑incorporation contract is any agreement entered into in the name of a company that has not yet been incorporated. For example, two founders might agree a lease for premises, enter into a supply contract, or sign terms with a software provider before the company is legally formed. From a commercial perspective, these acts may seem necessary to get a business started quickly, but legally they carry significant risk.
Statutory Rule under Companies Act 2006
Section 51 of the Companies Act 2006 states that:
“A contract that purports to be made by or on behalf of a company at a time when the company has not been formed has effect, subject to any agreement to the contrary, as one made with the person purporting to act for the company or as agent for it, and he is personally liable on the contract accordingly.”
This means that if an individual signs a contract “for and on behalf of” a company that does not yet legally exist, that individual is treated in law as the contractual party. The company cannot retrospectively ratify or adopt the contract to transfer liability because it did not exist at the relevant time, and a non‑existent principal cannot authorise or ratify acts purportedly done on its behalf.
Case Law Illustrating Personal Liability
A leading case on this point is Kelner v Baxter (1866), where promoters of a hotel company entered into a contract for purchasing wine before the company was incorporated. The court held that, because the company did not exist at the time, the promoters were personally liable for the contract when the company later failed to perform.
A more modern illustration is Royal Mail Estates Ltd v Maple Teesdale Borzou Chaharsough Shirazi [2015] EWHC 1890 (Ch), where a property purchase contract was signed on behalf of a company that had not yet been incorporated. The High Court upheld that the individual signatories could be personally liable under the statutory rule, as there was no effective “agreement to the contrary” excluding that outcome.
Key Legal Risks of Acting Before Incorporation
1. Personal Liability for Contracts
As explained, individuals who enter into contracts on behalf of a not‑yet‑formed company may be personally liable for obligations under those contracts. Creditors and third parties can enforce the contract against the person who signed, even though they intended the company to be liable once formed.
This liability is not limited to commercial debts. An individual may be personally accountable for damages, performance obligations, or other contractual liabilities. Even if the company is later incorporated and accepts the benefit of a contract, the original signatory's personal liability may continue unless a novation or a clear “agreement to the contrary” is agreed with the other party.
2. No Ratification by the Company
Unlike ordinary agency where a principal can ratify a contract entered by an agent, a company cannot ratify a pre‑incorporation contract because it did not exist at the relevant time. Consequently, the company cannot retrospectively become a party to the contract by simple ratification once formed: the statutory rule expressly prevents this outcome.
3. Lack of Contractual Capacity
Because a non‑existent company lacks legal capacity, any actions taken in its name are effectively void or of no legal effect as to the company itself. This can make enforcement difficult and uncertain for third parties and exposes promoters to personal claims.
4. Director and Promoter Exposure
Individuals acting in anticipation of incorporation may be viewed as promoters or de facto agents. They may be personally responsible for contractual penalties, claims for compensation, and obligations assumed in the company's name. Importantly, such actions occur outside the protections afforded to directors and officers after formal incorporation, including indemnification and limited liability.
Managing and Mitigating Risks
Novation Agreements
One common method to mitigate pre‑incorporation risk is to enter into a novation after incorporation. This means the original contract is replaced by a new contract between the third party and the now‑formed company, extinguishing personal liability for the individual who originally signed. All parties must agree to the novation for it to be effective.
Explicit Contractual Terms
In limited circumstances, contracts can include an “agreement to the contrary” specifying that the signatory will not incur personal liability under the statutory rule. However, case law indicates that such wording must be clear and unambiguous, and parties must know the company was not yet incorporated for this provision to exclude liability under s 51.
Delay Contracting Until Incorporation
The safest practical approach is to delay entering binding obligations until after the company has been formally incorporated. Checking the Companies House register before contracting is a straightforward precaution for third parties dealing with a purported company.
Legal Advice and Documentation
Obtaining legal advice before agreeing to pre‑incorporation arrangements can help clarify liabilities, draft appropriate protective clauses, and advise on risks related to potential future litigation, contract breaches, or indemnity claims.
Common Questions
Can a Company Ratify a Pre‑incorporation Contract?
No. Under UK law, because a company did not exist at the time the contract was formed, it cannot retrospectively ratify a pre‑incorporation contract to create binding obligations on itself.
Is Personal Liability Avoidable?
Personal liability can sometimes be avoided if a novation agreement is entered after incorporation, or if the original contract expressly and clearly excludes personal liability under s 51. However, the courts interpret such “agreements to the contrary” restrictively, and they generally require explicit intent.
What Happens if the Company Never Incorporates?
If the company is never incorporated, there is no legal entity to assume liability, so the individual who entered into arrangements remains personally liable. Third parties can pursue that individual for performance or damages.
Key Takeaways
Acting before a company has been incorporated in England and Wales carries significant legal risks because the company lacks legal personality and cannot enter into binding obligations. Under section 51 of the Companies Act 2006, contracts and deeds purportedly made on behalf of an unformed company are treated as contracts with the individual who signed, exposing them to personal liability for performance and any related claims. Case law such as Kelner v Baxter (1866) and Royal Mail Estates v Maples Teesdale [2015] EWHC 1890 illustrates how courts enforce this principle and require clear “agreement to the contrary” to avoid personal responsibility. To manage these risks, parties should consider delaying contracting until after incorporation, using novation agreements with all parties' consent, and seeking legal guidance when preliminary commitments are necessary.
