What legal support do founders need before a pre-seed round?

By SuLe · Updated 5 October 2026
Reviewed by Patricia Wing, corporate lawyer and founder of SuLe

A first-time UK founder needs legal help in three places before a pre-seed round. The company's records have to be investor-ready before outreach, the term sheet needs a review before anyone signs it, and the investment has to be drafted so angels can claim SEIS or EIS relief. SuLe gives UK founders a free cap table, a free term sheet reviewer, a free legal health check and, at fixed fees, lawyers who respond within two hours, all on one platform.

Seed money got harder to win in 2025. The British Business Bank's Small Business Equity Tracker 2026 reported that UK seed-stage deal numbers fell 27% in 2025, to 704, while seed investment held steady at £2.1 billion. The Bank reads that as capital spread across fewer companies, and seed-stage companies waited a median 14.4 months between funding rounds, up from 12.4 months in 2024. When investors can choose, a gap in the legal records gives them an easy reason to pass.

What to fix before any investor sees the company

Legal readiness means checking that the company's records say what the founder believes they say, before an investor's due diligence does it for them.

A UK Space Agency checklist on GOV.UK says outdated or inconsistent records, such as missing filings, undisclosed liabilities or gaps in IP ownership, can raise immediate red flags, and warns that a lack of assignment agreements from contractors can derail investment quickly. The UK Business Angels Association's guide to due diligence lists legal as one of five areas investors examine, covering how the business was set up, ownership and shareholdings, employment contracts, IP ownership and existing commercial contracts.

A pre-seed legal-readiness review covers eight areas.

Legal areaWhat the lawyer checks
Incorporation and governanceCertificate of incorporation, current articles, minute books, filing history
Ownership and cap tableIssued shares, classes, allotment authorities, resolutions, Companies House records
Founder arrangementsEquity split, vesting, departure provisions, IP assignment
EmploymentContracts, IP and confidentiality clauses, contractor agreements
IP chainCopyright ownership, assignment agreements, registrations, licence terms
Commercial contractsMaterial customer, supplier and partnership agreements
Liabilities and disputesLoans, guarantees, outstanding claims or regulatory issues
Financial and tax recordsFiled accounts, tax position, SEIS or EIS eligibility if relevant

A first pass can be free. SuLe's legal health check takes about three minutes, covers the twelve key questions investors ask about the cap table, founder agreements, team contracts, IP and compliance, and returns the specific gaps an investor would flag in due diligence, with the document or tool that closes each one. SuLe's free due diligence checklist then covers the documents that make the data room investor-ready.

Rebuild the cap table before you model the round

A spreadsheet cap table is not the legal record. The legal cap table reconciles the spreadsheet against the articles of association, allotment authorities, board and shareholder resolutions, Companies House filings, option documents, outstanding ASAs and any undocumented promises made to early contributors.

Reconstructing it takes five steps.

  1. List every share issue since incorporation, with the date, class, quantity and consideration.
  2. Confirm allotment authority existed for each issue and that pre-emption rights were satisfied or waived by resolution.
  3. Map every outstanding option, warrant and convertible instrument, including any ASA's discount, valuation cap and longstop date.
  4. Cross-reference each event against Companies House. New share issues must be reported within a month and all other changes to the share structure within 21 days, according to GOV.UK guidance on share structure changes.
  5. Identify any undocumented equity promises and decide whether to formalise or extinguish them before the round.

SuLe's cap table is free and starts from the company's Companies House record or an existing spreadsheet. It records ASAs, convertible loan notes and SAFEs with their discounts, caps and longstop dates, shows issued and fully diluted ownership in one view, and exports to Excel. A SuLe lawyer works from the same cap table, so the reconciliation happens on a live record instead of one rebuilt from inboxes.

Shareholders' agreements and IP assignments are part of investor readiness

By pre-seed, the founders' deal belongs in a shareholders' agreement and the articles. SuLe's guide to founders' and shareholders' agreements explains that the shareholders' agreement covers share rights, vesting and leavers, transfers, drag-along and tag-along rights, and reserved matters, and that vesting and buyback mechanics only gain teeth once they sit in the shareholders' agreement or articles.

A founders' agreement records roles, the equity split, vesting and what happens to shares and IP if a founder leaves, and a team can sign it before the company exists. A company that is already incorporated with investors arriving should go straight to a shareholders' agreement, as SuLe's founders' agreement guide puts it, because there is no point papering the early deal twice.

IP ownership is a separate question and just as urgent. GOV.UK's guidance on copyright ownership says an employer is the first owner of work an employee creates in the course of employment, but a contractor working under a contract for services usually keeps the copyright unless there is a contractual agreement to the contrary. Where the contract is silent, a court may find an implied licence to use the work, which does not necessarily transfer ownership.

Take a founder who pays a contractor £8,000 to build the first version of the product. Every invoice is paid, and there is no written IP assignment. The contractor, not the company, will usually own the copyright in the core product, which is the kind of gap the UK Space Agency checklist says can derail investment.

The fix is a written assignment of the existing copyright, signed by the contractor before the data room opens. Paying the invoice is not enough, as SuLe's guide to employee and contractor IP explains, and the longer the gap, the more likely the contractor is unreachable or unwilling.

Get the term sheet reviewed before you sign it

Term sheet review has to happen before signature, because by the time the long-form documents arrive the main terms are set.

The British Business Bank's term-sheet guidance explains that a term sheet is usually non-binding as a whole, but some clauses may bind. Confidentiality may bind from the outset, governing-law clauses can apply immediately, and an exclusivity clause can be legally enforceable if clearly worded. A founder who signs without review may already be locked into a no-shop period, and the Bank says most no-shops last around 30 to 90 days.

The economic terms matter even though they are not yet binding. Valuation, the option pool, liquidation preferences, voting rights and anti-dilution provisions become the template for the definitive documents, and the Bank notes that a term sheet is likely to influence later rounds because it sets a precedent. An option pool created before the investment dilutes the founders, not the incoming investor.

Engage a lawyer before the term sheet arrives. Counsel who already knows the company can respond quickly when the document lands, instead of starting from a cold briefing mid-negotiation.

SuLe's free term sheet reviewer gives a founder a fast first read. Upload the term sheet, and it flags risky clauses, grades them by risk, explains them in plain English and suggests redlines to take to the investor. For a judgement on their own round, every paid SuLe plan comes with half an hour of lawyer time each month.

Fast pre-seed money can create a slow SEIS problem

Many UK pre-seed rounds use an advance subscription agreement (ASA) rather than a priced equity round. The investor pays now and receives shares at the next priced round, usually at a discount to that round's share price. It is a common route for an angel round where the company does not want to set a valuation yet, and it can be SEIS and EIS compatible if drafted correctly.

The company has to qualify first. According to HMRC's SEIS guidance, a company can raise up to £250,000 through SEIS, must have gross assets of no more than £350,000 when the shares are issued, must have fewer than 25 full-time equivalent employees, and must not have been carrying on its qualifying trade for more than 3 years. SuLe's guide to SEIS eligibility adds that the company's activities must not be on HMRC's excluded list and that it must pass the risk-to-capital condition.

The ASA has to qualify too. HMRC's manual at VCM33025 accepts an ASA for SEIS only if the payment cannot be refunded in any circumstances, the agreement cannot be varied, cancelled or assigned, it bears no interest, and it has a longstop date by which the shares must be issued. As a general rule HMRC expects that longstop to be no more than 6 months from signing. The same page says a company that wants advance assurance should apply before the ASA is entered into, and that relief is available only from the date the shares are issued.

For most UK startups this makes an ASA a better choice than a US-style SAFE. A UK company can legally sign a SAFE, but as SuLe's guide to ASAs and SAFEs explains, a standard SAFE has no longstop date and needs restructuring before it protects the investors' relief.

Financial promotions, data rooms and the post-close calendar

Financial promotions. A business plan, executive summary or other material used to attract investment is likely to be a financial promotion. GOV.UK's legal considerations for raising equity explains that making one without an exemption or approval is a criminal offence, and sets out the exemptions start-ups commonly rely on, such as communications to certified high net worth individuals and self-certified sophisticated investors. SuLe's guide to financial promotion rules adds that the rules apply whatever the medium, so a deck, an email, a LinkedIn post or a direct message can each be a financial promotion. Ask a SuLe lawyer before broad outreach to identify the permitted audience, the exemption and any required wording.

Staged data rooms. The UK Space Agency checklist recommends granting access by investor tier and having NDAs in place before sharing sensitive files. According to SuLe's data room guide, building should start before the term sheet, and documents in the room are often treated as generally disclosed for warranty purposes. Share constitutional documents and a summary at first contact, and add the cap table, team agreements, contracts and financial records as interest firms up.

Post-close calendar. Anyone who becomes a person with significant control after 18 November 2025 must provide their Companies House personal code when added to the register or within 14 days, according to Companies House identity verification guidance. For SEIS, the company can submit its SEIS1 compliance statement only after the shares are issued and once it has traded for at least 4 months or spent at least 70% of the money raised, and it must follow the scheme rules for at least 3 years after the investment, per HMRC's SEIS guidance.

SuLe vs a traditional senior lawyer for pre-seed prep

SuLe's lawyers worked at top city and international firms such as Orrick and Bird & Bird. SuLe puts that experience behind published prices, where a traditional firm usually bills by the hour.

The guideline rate comes from GOV.UK's solicitors' guideline hourly rates, in effect from 1 January 2026. It is a guideline figure for the summary assessment of court costs, so treat it as a benchmark for senior London time. Firms set their own rates. SuLe's prices are on its pricing page and the lawyer response time is on its platform page.

SuLe fits a founder who wants the cap table, the health check, term sheet review and a senior lawyer in one place at a published price, as SuLe's own comparison with traditional law firms sets out.

Frequently asked questions

When should a first-time founder get legal support for a pre-seed round?

Before investor outreach starts. The most useful work happens before investors see the company, when the cap table can be repaired, founder arrangements formalised, IP gaps closed and financial promotions checked.

Do founders need a founders' agreement or a shareholders' agreement before pre-seed?

A shareholders' agreement, with articles to match. A founders' agreement is the only founder document that can be signed before incorporation, and it records roles, the equity split, vesting, IP and what happens if a founder leaves. Once the company exists, and certainly by the first investment round, a shareholders' agreement should take over and restate the vesting and leaver terms, as SuLe's comparison of the two agreements sets out.

Can a term sheet be legally binding?

Partly. Most of it is not binding, but the British Business Bank notes that a no-shop clause, which stops the company seeking offers from other investors, can be enforced when it is clearly worded. The Bank warns that a no-shop that runs too long lets an investor take its time over due diligence and still drop out at the last moment.

Can an ASA qualify for SEIS in a UK pre-seed round?

Yes, if it is drafted for it. HMRC's manual requires the ASA to be non-refundable, interest-free, incapable of variation, cancellation or assignment, and to contain a longstop date, which as a general rule HMRC expects within 6 months of the date the ASA is entered into. As SuLe's ASA vs SAFE guide explains, a standard SAFE needs restructuring to meet those conditions.

How much does a lawyer cost for pre-seed legal work?

It depends on the route. SuLe's paid plans cost £299 a quarter or £990 a year, plus VAT, and each includes 30 minutes of lawyer time a month, with further work quoted as a fixed price based on a £300 standard hourly rate, per SuLe's comparison with traditional law firms. Law firms usually bill by the hour, and the court guideline rate for the most experienced grade doing very heavy commercial and corporate work at a centrally based London firm is £579 an hour from 1 January 2026, per GOV.UK.

What belongs in a pre-seed legal data room?

At minimum, current constitutional documents and approvals, the cap table and full share history, founder and employment agreements, contractor IP assignments, material commercial contracts, debt and funding documents, financial and tax records, regulatory compliance evidence and a schedule of any disputes or liabilities. SuLe's data room guide sorts them into corporate, share capital, tax, IP, commercial, people, compliance and finance folders. The UK Space Agency checklist suggests indexed folders for financial, legal and IP, commercial, regulatory and governance records, and the UKBAA's due diligence guide lists the legal documents investors generally expect to receive.

SEIS and EIS relief depends on the company and the investor meeting HMRC's conditions and on the investor's own tax position. We recommend seeking tax advice to confirm the position.
