The practical question is not simply, “Which documents exist?” It is: Which legal risks need to be controlled at this stage of the business? This guide explains the main documents, when they usually matter and whether the appropriate next step is guided drafting, a downloadable template or legal support.

UK startup legal documents at a glance

1. Incorporation documents and statutory company records

A business cannot operate as a limited company until it has been incorporated at Companies House. The incorporation process involves the memorandum of association, articles of association, a statement of capital or guarantee, details of directors and people with significant control, the registered office and other required information. See the Companies House incorporation guidance.

After incorporation, the company must make continuing filings and keep its records up to date. From 18 November 2025, companies no longer have to keep separate internal registers of directors, directors’ residential addresses, secretaries or people with significant control, but that information must still be registered with Companies House and kept current. The company must still maintain its register of members. See the Companies House register changes.

Identity verification also became a legal requirement from 18 November 2025, with a transitional timetable for directors and people with significant control. Check the current Companies House identity-verification guidance for the applicable due date and process.

• Core formation documents and records commonly include: certificate of incorporation, memorandum, articles, statement of capital and initial shareholdings, register of members and records of directors’ and shareholders’ decisions.
• Consider bespoke or amended articles where: there are different share classes, unusual voting or transfer rights, founder vesting arrangements, external investment or a structure that model articles do not adequately address.

For help with entity choice, incorporation, bespoke articles or ownership structure, see Business Formation and Business Structure.

2. Founders’ Agreement and ownership arrangements

A Founders’ Agreement is not generally required by law, but it can reduce uncertainty while the founders are still aligned. It can document roles, decision-making, equity expectations, contributions, confidentiality, intellectual property, founder departures and dispute procedures.

• Equity ownership and what each founder is expected to contribute
• Roles, time commitments and decision-making authority
• Reverse vesting, leaver treatment and what happens if a founder stops contributing
• Ownership and transfer of intellectual property
• Confidentiality, restrictions and dispute escalation

3. Employment, contractor and services documents

Employees

Employers must provide employees and workers with a written statement of the main employment particulars. The principal statement is required on the first day and the wider statement within two months. The written statement is not, by itself, the same as the full employment contract. See the GOV.UK written-statement guidance.

• Role, duties, pay, hours, place of work, holiday, benefits and probation
• Confidentiality, intellectual-property provisions and data-protection information
• Notice, disciplinary and grievance procedures, and appropriate post-termination restrictions

Contractors, consultants and service providers

A written agreement should define the services, deliverables, payment, timetable, confidentiality, intellectual-property ownership, liability, termination and practical working arrangements. However, calling someone a contractor does not determine their legal status; the actual relationship and working practices matter.

4. Intellectual-property ownership and protection

A startup should be able to show that it owns or has permission to use the software, designs, content, inventions, branding and other assets on which the business depends. Payment for work does not necessarily transfer ownership, particularly where founders, contractors or collaborators created material before incorporation or outside an employment relationship.

• Identify who created each important asset and under which agreement
• Use an express assignment where ownership did not automatically pass to the company
• Address moral rights, further-assurance obligations and delivery of source materials where relevant
• Consider trade mark, design, patent or other registration strategies separately from contractual ownership

5. Customer, supplier and commercial agreements

Once the startup begins trading, its contracts should reflect what it sells, who the customer is, how orders are accepted, what each party must do and what happens if the relationship ends or something goes wrong.

Consumer-facing businesses must also address statutory information, fairness and cancellation requirements. For many distance sales, customers must be told about a 14-day cancellation right, subject to the applicable rules and exceptions. See the GOV.UK online and distance selling guidance.

For bespoke or negotiated customer, supplier, distribution or platform arrangements, see Commercial Agreements (UK).

6. Website, privacy, cookies and data documents

Where a startup collects personal data, the UK GDPR requires it to provide appropriate privacy information. That information must reflect what the business actually collects, why it uses the data, its lawful bases, retention, sharing, transfers, rights and contact arrangements. See the ICO privacy-information guidance.

If the website or app uses non-essential cookies or similar technologies, consent generally requires a clear positive action, and users should be able to enable or disable non-essential cookies. See the ICO cookie guidance.

• Privacy Policy or privacy notice tailored to the actual data flows
• Cookie Policy and a consent mechanism that matches the technologies used
• Website Terms of Use and, where appropriate, customer or subscription terms
• Refund and Cancellation Policy for the relevant offering
• Data Processing Agreement where required for controller/processor relationships

7. Marketplace and platform documents

Marketplaces and platforms often need more than general website terms because the operator is setting rules among several groups: users, sellers, hosts, vendors, creators or service providers. The document set should reflect who contracts with whom, the operator’s role, payments, cancellations, prohibited content, enforcement and dispute handling.

• Marketplace Terms of Use
• Marketplace Seller Terms or Host / Vendor Agreement
• Platform-Focused Privacy Policy
• Content Policy and Acceptable Use Policy
• Platform Moderation Terms
• Host Declaration where appropriate

8. Non-Disclosure Agreements and confidentiality

An NDA can help define confidential information, permitted use, disclosure limits, security, duration and remedies. It is most useful when the information and purpose are clear. It should sit alongside practical controls such as access restrictions, labelling, secure data rooms and careful disclosure sequencing.

• Use a unilateral structure where one side is principally disclosing information
• Use a mutual structure where both sides expect to disclose confidential information
• Do not assume an investor or potential customer will sign an NDA before an initial discussion

9. Loan and investment documents

Business borrowing

A business loan should normally record the amount, purpose, interest, repayment, events of default, early repayment, representations and approvals. Security, guarantees, director or shareholder relationships and regulated lending issues may require additional documents or advice.

Equity and convertible investment

An equity or convertible funding round can involve a term sheet, subscription or investment agreement, amended articles, Shareholders’ Agreement, board and shareholder approvals, disclosure documents, share certificates and Companies House filings. The correct package depends on the instrument and negotiated terms.

Where SEIS or EIS is relevant, HMRC advance assurance can indicate whether certain scheme conditions appear to be met based on the information provided, but it is not a general endorsement or a guarantee about an investor’s eligibility. See the HMRC advance-assurance guidance.

10. Ongoing governance and compliance records

Good governance records make it easier to show who owns the company, who approved important decisions and whether filings have been made. They can become critical during investment, a sale, due diligence, a dispute or an audit.

• Register of members and up-to-date cap table
• Board minutes and written board decisions
• Shareholder resolutions and copies of filed resolutions where required
• Share certificates, allotment and transfer records
• Annual accounts, confirmation statements and other Companies House filings
• Records of director, registered-office, PSC and other changes reported to Companies House

For support with ongoing filings, capital changes, reorganisations or governance remediation, see Corporate and Regulatory Compliance.

A practical legal-document roadmap by startup stage

When StartWise is appropriate — and when it is not

StartWise is designed to give founders and growing businesses a structured route to a tailored first draft through guided, document-specific questions and reusable business profiles. It is not a general AI chatbot and it is not legal advice, lawyer review, legal approval or legal sign-off.

StartWise may be a practical starting point where:

• a current workflow closely matches a routine business need;
• the arrangement is reasonably standard and the parties are not heavily negotiating;
• the user can provide accurate information and understands the commercial choices being made;
• a structured first draft would be more useful than starting from a blank prompt or generic form.

A consultation or bespoke engagement may be more appropriate where:

• the matter is complex, heavily negotiated, cross-border or commercially sensitive;
• the document affects founder equity, investment, tax, employee status or regulated activities;
• the business operates a consumer-facing or regulated platform;
• there is a dispute, unusual risk allocation or uncertainty over the correct document or jurisdiction.

Prefer a static downloadable template?

A static template may be suitable where you have already identified the correct document, the matter is straightforward and you are comfortable adapting the wording. The following are exact matching listings from the Entrepreneur Legal UK Etsy store; they are secondary options rather than substitutes for choosing the correct document or obtaining advice where needed.

Common mistakes UK startups make

• Using a document designed for another jurisdiction without adapting it to UK law and the actual transaction.
• Treating a Founders’ Agreement and Shareholders’ Agreement as interchangeable.
• Assuming payment to a contractor automatically transfers all intellectual property to the company.
• Calling someone a contractor without checking how the relationship operates in practice.
• Copying a privacy policy that does not describe the business’s real data collection and sharing.
• Using website terms when the business also needs customer, subscription, marketplace or supplier terms.
• Waiting until investment or due diligence to repair missing ownership and governance records.
• Assuming that a template, an AI output or a StartWise draft has been legally reviewed when no separate review has been agreed.

Frequently asked questions

Does a UK startup need every document immediately?

No. Formation and statutory obligations come first. Other documents should be introduced when the related risk arises: co-founder ownership, contractor work, employment, customer trading, personal-data use, borrowing or investment.

Is a Founders’ Agreement legally required?

Usually no, but it can be commercially important because it records expectations before a disagreement or founder departure occurs. It may need to work alongside the articles, share terms and later shareholder arrangements.

Are legal templates enforceable in the UK?

A contract is not enforceable merely because it is called a legal template. Its effect depends on the parties, subject matter, wording, applicable law, formation, fairness, execution and surrounding circumstances. A suitable template can be a useful starting point for a straightforward matter, but it does not guarantee suitability or enforceability.

Can StartWise create every document a startup needs?

No. StartWise is currently in early access with a focused set of live UK workflows. More workflows are listed as coming soon. Where the required document is unavailable, the user can request a workflow or contact Entrepreneur Legal UK about review, consultation or bespoke support.

When should a startup speak to a lawyer?

Legal support is particularly sensible for investment, bespoke articles, complex founder equity, employment status, senior hires, regulated or cross-border activity, consumer-facing platforms, disputed IP, material negotiations and matters where getting the document wrong could have significant commercial consequences.

Final checklist

• Confirm the company’s incorporation, ownership and Companies House information are correct.
• Document founder roles, equity expectations and intellectual-property ownership.
• Use appropriate agreements for employees, contractors and service providers.
• Put customer, website, privacy, cookie and refund terms in place before the relevant activity begins.
• Use NDAs selectively and protect confidentiality operationally as well as contractually.
• Prepare loan or investment documents that match the actual funding instrument.
• Keep registers, approvals, share records and filings organised and current.
• Choose guided drafting, a static template or legal support according to the matter’s complexity and risk.
