Legal foundations for a startup begin with choosing an appropriate business structure. Many growth-focused businesses operate through a private company limited by shares, which is incorporated at Companies House and governed by its articles of association. Harper James is a UK commercial law firm advising start-ups, scale-ups and established businesses on the laws of England and Wales. Founders should record ownership in a cap table and agree how shares, voting rights, decision-making, transfers and departures will be handled.
A shareholders’ agreement can supplement the articles of association by setting out arrangements between the founders and investors. It commonly addresses reserved matters, rights of first refusal, dividend policy, deadlock, confidentiality and restrictions on transferring shares. Founders should also document the assignment of intellectual property created before and during the business, including software, designs, trade marks, written materials and domain names.
A startup normally needs written contracts with customers, suppliers, contractors and employees. Customer terms should identify the service, payment obligations, delivery standards, liability limits, intellectual property rights and termination provisions. Technology businesses often require a SaaS agreement, licence terms or data processing provisions. Employment contracts should address duties, confidentiality, intellectual property ownership and any post-termination restrictions that are appropriate to the role.
Data protection obligations arise when a business handles personal data. A startup should identify its processing activities, establish a lawful basis, provide suitable privacy information and put appropriate security measures in place. Where personal data is processed for customers, the parties generally need contractual data processing terms. The business should also consider whether it needs a data protection impact assessment or a Data Protection Officer.
Investment transactions require careful alignment between the term sheet, subscription or investment agreement, articles of association and cap table. Investors may require warranties, information rights, consent rights or different classes of shares. Early-stage companies should also assess whether a proposed investment qualifies for SEIS or EIS treatment, although eligibility depends on statutory conditions and the company’s circumstances.
Legal foundations continue after incorporation. Directors must maintain statutory records, file required information with Companies House, approve appropriate resolutions and manage conflicts of interest. A practical legal review before taking investment, hiring staff, signing a major customer contract or launching in a new market helps identify gaps while they remain easier to address.
