Raising capital can be one of the most exciting milestones in your business journey. It can also be one of the easiest places to make expensive mistakes.
If you’re a UK startup or SME thinking about bringing in investors, taking on venture debt, or even just formalising funding from friends and family, it’s worth understanding what corporate finance solicitors actually do (and why the legal side isn’t just “paperwork”).
In plain terms: a good funding round doesn’t just get you money. It sets your business up to scale, protects your control, and helps avoid disputes that can derail growth later.
Below, we’ll break down what to expect when raising capital in the UK, where corporate finance solicitors fit in, and the key documents and legal checks you’ll want to have sorted before you sign anything.
What Do Corporate Finance Solicitors Actually Do For SMEs And Startups?
Corporate finance solicitors help you structure, negotiate, and document funding and other major business transactions. While “corporate finance” can sound like it’s only for big companies, the reality is that many of the same issues show up for SMEs and startups - just with tighter budgets, faster timelines, and more at stake personally for founders.
Depending on your situation, corporate finance solicitors may help you:
- Choose the right funding structure (equity vs debt vs hybrid options).
- Negotiate investor terms so you don’t give away more control (or future value) than you intended.
- Draft and review key fundraising documents like term sheets, subscription agreements, and shareholders’ arrangements.
- Run a legal due diligence process (or help you respond to investor due diligence).
- Make sure Companies House filings and corporate approvals are done correctly (for example: board minutes, shareholder resolutions, authorities to allot shares, dealing with any statutory pre-emption rights, updating registers, and filing the right forms on time).
- Flag legal risks early, like IP ownership gaps, problematic customer contracts, or employee issues that could make investors nervous.
Think of it like this: fundraising is not just about getting a “yes” from an investor. It’s about locking in a deal you can live with for the next 3–7 years (and through future rounds).
Why The Legal Side Matters More Than Founders Often Expect
It’s common for founders to focus on valuation and how much cash they’ll receive. But investors often care just as much about the controls in the documents, such as:
- who can appoint directors;
- what decisions require investor consent;
- how future fundraising affects existing shareholders (including anti-dilution and pre-emption mechanics);
- what happens if a founder leaves;
- what information rights and reporting obligations you have;
- how an exit is handled (drag-along, tag-along, liquidation preference, etc).
Those terms can be the difference between building confidently and constantly feeling like you need permission to run your own company.
When Should You Speak To Corporate Finance Solicitors During A Fundraising?
Most founders reach out too late - often once a term sheet is “agreed” and they’ve already made verbal commitments.
As a rule of thumb, it’s smart to speak to corporate finance solicitors when:
- You’re about to share numbers or terms with investors and want to sanity-check what’s market and what’s risky (including any UK financial promotion implications if you’re pitching or circulating materials).
- You’ve received a term sheet (even a “non-binding” one).
- You’re raising from friends and family and want to avoid relationship-damaging misunderstandings.
- You’re doing a convertible note or SAFE and want clarity on what it means for your next round (and how it sits with UK-style “advance subscription” structures).
- You’re about to take money from an investor who wants “special rights” (like veto rights, preferential returns, or a board seat).
- You’re approaching your first institutional round where due diligence will be more intense.
A Quick Reality Check: “Non-Binding” Doesn’t Mean “No Consequences”
Term sheets are often described as non-binding, but they still matter. They set expectations, they shape negotiations, and they can include binding provisions (like confidentiality and exclusivity/no-shop clauses).
Even where nothing is legally binding, it can be commercially hard to walk back a term you’ve already “agreed”, especially if you’ve told other investors you’re proceeding.
Getting advice early usually costs less than trying to renegotiate after everyone thinks the deal is done.
What Funding Options Are Common For UK SMEs And Startups?
There’s no one “right” way to raise capital. The best structure depends on your stage, cashflow, risk appetite, and what you’re trying to achieve (growth, runway, acquisition, hiring, product build, and so on).
Equity Investment (Issuing Shares)
Equity funding means you issue shares in your company to investors in exchange for capital. This can include angel investors, seed funds, or strategic investors.
Key things to think about:
- Dilution: you (and any existing shareholders) give up a percentage of ownership.
- Control terms: investors may ask for voting rights, board seats, or veto rights.
- Company law mechanics: you’ll usually need the right authority to allot shares, and you may need to deal with statutory or contractual pre-emption rights before issuing new shares.
- Future rounds: the first equity deal often sets the “pattern” for future fundraising.
Equity rounds commonly involve a Share Subscription Agreement plus an updated Shareholders Agreement.
Convertible Notes (Debt That Converts To Equity Later)
Convertible notes are a popular early-stage option. They start as a loan, but convert into shares at a later funding round (often at a discount, and sometimes with a valuation cap).
For founders, this can feel “lighter” than negotiating a full equity round immediately - but it’s still a legal instrument with real consequences.
A properly drafted Convertible note should spell out:
- interest (if any) and repayment mechanics;
- what triggers conversion (next equity round, sale, maturity date);
- discount rate and valuation cap (if used);
- what happens if you don’t raise again before maturity.
SAFE-Style Instruments (Simplified Future Equity)
Some startups use SAFEs (Simple Agreements for Future Equity) or similar early-stage instruments. In the UK, SAFEs are often adapted into “advance subscription” style agreements (rather than used in a US form) so they work properly with UK company law and tax expectations.
These can be faster than a priced equity round, but they’re not “standard” in every UK context, and the details matter (especially around conversion triggers, long-stop dates, and investor protections).
If you’re considering this route, having a lawyer review the SAFE note terms can prevent nasty surprises later when you’re negotiating your next round.
Debt Finance (Loans)
Some SMEs raise capital through traditional loans, venture debt, or director/shareholder loans. Debt can help you avoid dilution, but it creates repayment obligations and may come with security over business assets.
It’s also important to check:
- whether the lender requires personal guarantees;
- what happens on default;
- any restrictions on future fundraising or dividends;
- how any security is documented and registered (for example, company charges are typically registered at Companies House within strict deadlines).
Debt funding can be a good fit if you have stable cashflow - but it can be risky if your business is still pre-revenue or highly variable month to month.
Key Fundraising Documents You’ll Probably Need (And What They’re Doing)
Most fundraising disputes don’t come from “bad people”. They come from unclear documents, assumptions, and rushed conversations.
Here are the key documents corporate finance solicitors will commonly focus on for SMEs and startups raising capital.
1. Term Sheet (The Deal’s Blueprint)
A term sheet sets out the high-level commercial terms. Even if it’s short, it’s doing heavy lifting.
It usually covers things like:
- investment amount and valuation;
- share class (ordinary vs preference) and key rights;
- board composition and governance;
- investor consent matters (reserved matters);
- liquidation preference and exit rights;
- any founder vesting or leaver provisions;
- timeline and conditions to completion;
- any exclusivity/no-shop period and who pays costs.
Founders often underestimate how much a “headline” term shapes everything that comes next. If the term sheet is vague or one-sided, the final documents usually follow that pattern.
It’s normal to get legal input on a Term sheet before you treat it as agreed.
2. Share Subscription Agreement (Where The Investment Happens)
This is the contract where the investor agrees to subscribe for shares and pay the money, and the company agrees to issue those shares under defined terms.
It often includes:
- completion mechanics (what must be signed/delivered);
- warranties from the company and founders;
- limitations on liability (how far warranties can be claimed);
- conditions precedent (things that must be fixed before investment).
This is where many legal risks sit, especially around warranties. If you give overly broad warranties without sensible caps, time limits, and disclosures, you can end up with personal exposure later.
3. Shareholders Agreement (How You’ll Actually Run The Company)
If you bring in external investors, a shareholders agreement becomes the “rulebook” for how decisions are made and what happens when things change.
A well-drafted Shareholders Agreement can cover:
- director appointment/removal rights;
- reserved matters requiring investor consent;
- dividend policy (if relevant);
- transfer restrictions and pre-emption rights;
- good leaver / bad leaver provisions;
- drag-along and tag-along rights on a sale;
- confidentiality and non-compete expectations (where appropriate).
For founders, this is often where “control” really lives - not just in your share percentage.
4. Founders Agreement (If You Haven’t Already Done One)
If you’re raising capital and you have multiple founders, investors will often want to see that the founders’ relationship is properly documented.
A Founders Agreement can help clarify:
- roles and decision-making;
- equity split and vesting (if used);
- what happens if a founder leaves;
- IP ownership and assignment;
- confidentiality and restrictions to protect the business.
If this isn’t sorted, it can become a red flag in due diligence - not because it’s “illegal”, but because it increases uncertainty and the risk of internal disputes.
5. IP Assignment (Making Sure The Company Owns What It’s Selling)
Investors typically want to know the company actually owns its intellectual property - for example, the software code, brand assets, product designs, or core content.
If founders or contractors built key assets personally (or under vague arrangements), you may need an IP assignment to formally transfer ownership to the company.
This is one of those issues that’s much easier to fix early than during a live round when the investor’s legal team is asking questions.
Due Diligence: What Investors Will Check (And How To Prepare)
Due diligence is the investor’s process of verifying that your business is what you say it is - and that there aren’t hidden legal or commercial problems.
For SMEs and startups, due diligence commonly focuses on practical risks rather than perfection. You don’t need to be a “big corporate” to pass due diligence, but you do need to be organised and honest about what’s in place and what isn’t.
Common Due Diligence Areas
- Company structure and filings: Companies House details, share capital, share allotments, confirmation statements.
- Cap table accuracy: who owns what, options, convertibles, and any side agreements.
- Key contracts: major customers, suppliers, partnerships, licensing arrangements.
- Employment and contractor arrangements: whether people are properly engaged and IP is protected.
- Intellectual property: ownership, registrations, and any disputes.
- Data protection: if you handle customer data, investors may expect GDPR-aligned practices (even early stage).
- Regulatory and marketing compliance: depending on your sector and how you’re raising, issues can include FCA permissions, financial promotions, and consumer law.
- Litigation and disputes: threatened claims, complaints, regulator issues.
How Corporate Finance Solicitors Help With Due Diligence
Corporate finance solicitors can help you prepare a clean “data room” (a structured set of documents), identify gaps early, and draft sensible disclosures.
This matters because many fundraising agreements include warranties - and the best way to reduce risk is to:
- limit warranties appropriately;
- disclose known issues clearly and in writing;
- fix what’s fixable before completion.
Done properly, due diligence isn’t just an investor hurdle - it’s a chance to strengthen your legal foundations and make the business easier to scale (and easier to sell one day).
How To Choose The Right Corporate Finance Solicitors For Your Raise
Not all legal support is the same, and fundraising is one area where experience and practical judgement really matter. You want a solicitor who can protect you without slowing the deal to a crawl.
Questions Worth Asking Before You Instruct Anyone
- Do they regularly act for startups and SMEs? Fundraising for early-stage businesses has its own rhythm and market norms.
- Can they explain terms in plain English? You should feel informed, not overwhelmed.
- Will they help you think strategically? The “legal” and “commercial” sides of fundraising are closely linked.
- Are they comfortable negotiating? You’ll often need someone who can push back firmly but reasonably.
- Do they understand future rounds? The first deal affects the next deal - you want documents that won’t box you in.
Try Not To Optimise For Speed Alone
It’s tempting to treat legal work as a box-ticking exercise so you can get the money in quickly. But if the documents are rushed, you may end up with:
- unclear rights and obligations between founders and investors;
- unexpected veto rights that slow decisions;
- warranties that create personal exposure;
- a cap table that becomes messy and hard to fundraise on later.
Getting the structure right early is one of the best ways to stay investable as you grow.
