How Much Does a Shareholder Agreement Actually Cost When You’re Bootstrapping?

You’ve just found your co-founder. You’re both putting in cash, time, or both. Someone mentioned you need a shareholder agreement. Then you Googled « shareholder agreement lawyer » and saw quotes starting at €3,000. For a document. When you haven’t even made your first euro yet.

Here’s the thing: you absolutely need this agreement (I’ll explain why skipping it is the most expensive mistake you can make). But you don’t need to drain your pre-seed runway to get one. Let me walk you through every option, from free templates to full legal service, with real prices and exactly what you’re trading off at each level.

Why the « We’ll Sort It Out Later » Approach Costs You €15,000+ When Things Go South

Before we talk cheap options, let’s be clear about what you’re actually protecting yourself from.

Without a shareholder agreement, you’re defaulting to whatever your country’s company law says. In France, that means a departing co-founder keeps 100% of their shares even if they leave after three months. In Belgium, you might need unanimous consent to sell the company -meaning one bitter ex-founder can block a €2M exit.

The average cost of a co-founder dispute without a proper SHA? Legal fees alone run €8,000-25,000 for mediation, more if it goes to court. That’s before counting the months of distraction, the deal that fell through, the investor who walked away.

A €500 shareholder agreement now versus a €20,000 problem in 18 months. That’s the actual math.

The Four Real Options: Template to Full-Service, With Actual Prices

Option 1: Free Online Templates (€0)
Sites like Docracy, Wonder.Legal, or your local chamber of commerce offer free SHA templates. You’ll get a basic framework covering shareholding percentages, maybe some transfer restrictions.

What you won’t get: vesting schedules, drag-along rights, anti-dilution clauses, or anything calibrated to venture financing. These templates are built for two people opening a bakery together, not for a startup that might raise €500K in 18 months.

Use this only if: you’re testing a side project with a friend, stakes are genuinely low, and you both understand you’ll need a real agreement before taking any investment.

Option 2: Legal Tech Platforms (€150-400)
Platforms like SeedLegals (UK-focused, ~£500 for SHA), Stripe Atlas (US Delaware, ~$500 package), or Qonto’s legal partners in France offer semi-automated shareholder agreements. You fill in variables, their system generates a document, and sometimes a lawyer does a light review.

Pros: Much better than free templates, usually includes vesting and basic investor-friendly clauses.

Cons: Limited customisation. If you need specific reserved matters, unusual equity splits, or cross-border structures, you’ll hit walls fast.

Option 3: AI-Native Law Firms (€400-1,200)
This is the newer category. Firms like Lina Law use AI to handle 80% of the drafting, then have senior lawyers review and customise. You get a venture-backed SHA covering vesting, transfer restrictions, drag-along, pre-emption -the works -at roughly 30-50% of traditional firm pricing.

Turnaround is typically 3-5 days versus 2-3 weeks at a traditional firm. You get a fixed quote upfront rather than hourly billing that balloons unpredictably.

Option 4: Traditional Law Firms (€2,000-8,000)
A corporate lawyer at a mid-sized firm bills €250-400/hour. A shareholder agreement takes 8-20 hours depending on complexity. You’re looking at €2,000 minimum for something basic, €5,000-8,000 for a proper venture-ready agreement with international investor provisions.

Worth it if: you’re raising a €1M+ round, have complex multi-class share structures, or need jurisdiction-specific expertise that automated solutions can’t provide.

What Actually Needs to Be in There (The Non-Negotiables)

Whatever option you choose, your agreement is worthless without these five elements:

Vesting schedule: Standard is 4 years with a 1-year cliff. Without this, a co-founder who leaves after 6 months walks away with their full equity stake. I’ve seen this kill two startups personally.

Leaver provisions: What happens to unvested shares if someone quits? Gets fired? Dies? « Good leaver » typically keeps vested shares at fair market value. « Bad leaver » (fired for cause, joined a competitor) often forfeits everything or buys out at nominal value.

Transfer restrictions: Pre-emption rights (existing shareholders get first refusal on share sales), drag-along (majority can force minority to sell in an acquisition), tag-along (minority can join a sale on same terms).

Reserved matters: Which decisions need unanimous consent? Usually: changing share classes, issuing new shares, taking on debt above €X, selling the company. Without this, a 51% shareholder can dilute everyone else into oblivion.

Deadlock resolution: What happens when shareholders are 50/50 split on a critical decision? Mediation, escalation to an independent party, or structured buyout mechanisms.

Any solution that doesn’t address all five isn’t worth the paper it’s printed on.

The Hidden Costs Nobody Mentions Upfront

The sticker price isn’t the whole story.

Traditional firms: That €3,000 quote? It’s an estimate. Hourly billing means every email, every call, every revision adds up. Average overage on legal projects: 15-30%. Plus you’ll wait 2-4 weeks, and « urgent » often costs 50% more.

Legal tech platforms: Cheaper upfront, but many charge separately for modifications (€50-150 per change) or for legal questions that fall outside the template (€200+ for a 30-minute call). Lock-in contracts might require annual subscriptions.

DIY templates: The « free » option costs you 5-15 hours of your own time researching what should be included, plus the risk of missing something that costs you €50,000 later. Your time has value -if you’re billing €80/hour in consulting, that « free » template just cost you €800.

AI-native firms: Fixed pricing removes billing surprises, but check what’s included. Some cap revisions or charge separately for negotiation support once investors start red-lining your agreement.

Always ask: What exactly is included? What costs extra? What’s the turnaround guarantee?

How to Actually Get This Done This Week

Here’s your action plan based on your situation:

If you’re pre-product, testing with a co-founder, no money involved yet:
Use a free template to document basic principles (who owns what percentage, what happens if someone leaves). Commit to getting a proper agreement before incorporating or taking any money. Total cost: €0, time investment: 2 hours.

If you’re incorporating or about to take friends-and-family money:
Use a legal tech platform or AI-native firm. Budget €300-600. Make sure vesting, leaver provisions, and reserved matters are covered. Timeline: 1 week. Lina Law or similar services can turn around a venture-ready SHA in days with fixed pricing.

If you’re raising a seed round with institutional investors:
Investors will likely provide their own SHA template or heavily negotiate yours. Budget €800-2,000 for legal review and negotiation support. Your investors’ lawyers will spend 10x that on their side -you need someone in your corner.

If you already have investors and are adding a co-founder:
You probably need to amend your existing agreement. More complex, requires board consent, and you’ll want a lawyer. Budget €1,000-2,500 at an AI-native firm, €3,000-5,000 traditional.

The biggest mistake I see? Founders who spend €15,000 on a launch party but won’t spend €500 on the document that prevents their company from imploding. Get the agreement done this week. Your future self will thank you.
