A lawyer for your startup: when you need one, for what, and how to choose

Many founders hire a lawyer either too early, for things a template or an accountant handles well, or too late, when the problem already costs far more than the fee would have. This article is a map for buying legal help: which moments in a startup's life really need a lawyer, which don't, what kind of specialist you need, how you pay and how to recognise a good choice.

The legal mechanics of each topic - vesting, term sheets, employment contracts, tax, trademarks - are covered in depth in separate articles, which we link to. Here we explain why and when you need a lawyer for them. The prices quoted are indicative practice estimates, not a tariff.

1. Four questions before any decision

Before you pay for legal help, or decide you don't need it, ask yourself four questions:

1. Is there a deadline set by a court or a public authority? An order for payment, a Labour Inspectorate check, a tax audit, a complaint to the Commission for Personal Data Protection. Deadlines like these don't wait.
2. Does it touch the shares, the intellectual property, the people or the investors? These are the assets a buyer or investor will check first.
3. Can the mistake be fixed later? Some can't: an employment relationship can't be put in order retroactively, and a missed procedural deadline doesn't come back.
4. Is there a standard solution, or is the liability unlimited or personal? A standard, low-risk document can go with a template. Unlimited liability or a personal guarantee can't.

If all four answers are "no", you can probably manage alone or with an accountant. If at least one is "yes", the sections below show what exactly you need.

What it costs when one of these decisions is put off is shown in the most common legal mistakes startups make.

2. When you definitely need a lawyer

Founding with more than one partner

You can download an OOD's articles of association in minutes. The problem is that template articles almost always leave out the four things that decide the company's fate in a conflict: vesting (shares are earned over time, usually over 4 years with a one-year "cliff" before anything is earned), a deadlock mechanism (what happens when two equal partners can't reach a decision), transfer of the intellectual property created before and after incorporation, and rules for leaving and expulsion.

The law doesn't supply these automatically. A shareholders' agreement binds only those who sign it and doesn't replace the notarial form the law requires for transferring shares. So vesting in a Bulgarian OOD has to be built as a set of contractual obligations aligned with the articles of association - something a template can't do.

The price of such an agreement depends on the number of partners, how complex the vesting is, the matters that need everyone's consent, transfer restrictions, the deadlock mechanism, the language versions and the number of negotiation rounds. How these clauses work is explained in our articles on corporate structure and on co-founders and the law.

The first serious customer contract

There is no statutory or market threshold in euros above which a contract review becomes mandatory. What decides it is risk: how much you could lose relative to your turnover if something goes wrong. You need a lawyer when the contract has at least one of the following:

• Foreign law or foreign arbitration - the dispute will be fought under rules, and in a place, you don't know.
• No cap on liability - without one you owe full compensation for the damage, including the customer's lost profits, as far as they are a direct and foreseeable consequence. A cap can't exclude liability for intent or gross negligence, but without one your exposure is practically unlimited.
• Rights in software - the contract must state exactly which works, which right (exclusive or not), for which territory, for how long, for what payment and from what moment. "Rights pass on full payment" is a commercial choice, not an automatic rule.
• Other clauses that move money - penalties (sums agreed in advance for a breach), indemnities (obligations to compensate), a data processing agreement, service level guarantees (SLA), automatic renewal, exclusivity and personal guarantees from the founder.

The list of clauses to check from the other side of the table - when you are the buyer - is in the article on supplier contracts.

What the law settles by itself and what you negotiate when you sell to a business is in the article on customer contracts.

The first employee and the first outside developer

Bulgarian employment law is formal: hiring mistakes can't be fixed retroactively, and the notification to the tax authority has to be filed before the person starts work. Each missed case is sanctioned separately. A lawyer drafts the employment pack once - contract, job description, intellectual property and confidentiality clauses, GDPR information - and you then adapt it for each new hire.

Two questions need particular care. First, who owns the code: the rules for an employee and for an outside contractor on a civil contract differ, and with a contractor, without an express transfer, the rights stay with them. Second, a non-compete after the person leaves: the Labour Code doesn't regulate it, and the courts judge each case and routinely strike down general bans with no compensation and no reasonable limits in time and place. Both, along with the sanctions and deadlines, are covered in the employment law article.

Taking investment

A term sheet (the letter setting out the main terms of the investment) looks non-binding but usually contains clauses that bind you at once: confidentiality, exclusive negotiations, costs, governing law. Whether a clause binds depends on its wording, not on the heading.

Then comes the deal itself. Anglo-American concepts - drag-along (the majority can force the minority to sell), liquidation preference, anti-dilution protection - don't work automatically in a Bulgarian OOD. They have to be built through the shareholders' agreement, the articles of association and the notarial requirements for share transfers, with a capital increase, a general meeting decision and registration in the Commercial Register. That is work for a lawyer experienced in such deals. What in a term sheet is binding, which clauses move money and what the investor checks is described in the capital-raising guide, and raising from many small investors through a platform in the article on equity crowdfunding.

Receiving a legal threat

Not every letter is equally dangerous. Tell them apart:

• A letter from a lawyer or a private demand - no direct court effect, but a signal that a claim may follow.
• A notarial notice - officially certifies what you were told and when.
• An order for payment - issued by the court at the creditor's request, without hearing you. You can object within one month of service, a deadline that cannot be extended (Art. 414(2) of the Civil Procedure Code). If you don't object, the order becomes final. If you do, the creditor has to sue to prove the claim.
• An order for immediate enforcement - when the claim rests on, for example, a notarised contract or an extract from a bank's accounts, the creditor gets an enforcement title at once - the document that lets a bailiff start collecting the claim. The objection doesn't stop enforcement by itself: you need security or a request for a stay backed by written evidence, and the immediate-enforcement ruling is appealed within the same one-month deadline, together with the objection.

The objection deadline is preclusive: once it passes the right is lost, and the court checks this on its own. It can be restored only if you prove special unforeseen circumstances you couldn't overcome. This differs from the limitation period - it extinguishes the creditor's right to enforce the claim, but the court doesn't apply it on its own: you have to raise it expressly.

One more myth: in a trademark dispute your website or domain doesn't go down just because you received a letter. That takes an interim court order, which the other side has to request and justify.

What to do on day one, even before you call a lawyer:

1. Record the exact date, time and way it was served.
2. Keep all attachments and the envelope with the postmark.
3. Put the deadline in the calendar.
4. Stop direct contact with the other side until you've taken advice.
5. Preserve all related correspondence and documents - delete nothing.
6. Check whether the document comes from a court or a public authority, or is a private demand.

Selling the company

In a share sale, the company and the founder are separate persons, so the sale by itself doesn't make the founder personally liable for the company's debts. Personal liability arises when the founder signs personal guarantees, in cases of misrepresentation, or on a specific statutory ground. That's why the sale agreement needs to separate the guarantees given by the company from those the founders give personally.

The standard protections for a seller are a cap on liability, a minimum loss threshold below which nothing is owed, a limited period for the guarantees, a schedule disclosing known problems (which then can't be claimed as a breach), and mechanisms for part of the price: holding it in a separate account (escrow) or paying it according to future results (earn-out). Negotiating them is work for a deals lawyer.

Before the deal, the buyer will ask for access to your documents: corporate documents and registrations, the ownership table and capital history, the documents behind the rights in the code and trademarks, employment contracts with key people, tax returns and audits, GDPR records, key customer and supplier contracts, pending disputes, grants received, licences and related-party transactions. Whatever is missing becomes an argument for a lower price. What exactly the reviewer looks at is covered in the capital-raising guide.

Regulated activities

For some activities the question isn't whether but when to hire a specialist - before you launch:

• Payment services and e-money - a licence from the Bulgarian National Bank, anti-money-laundering rules and customer checks.
• Crypto-assets - the token's classification and the licence determine everything else. See the MiCA article.
• Medical software - if your software is a medical device under the EU regulation, you need classification, CE marking and assessment by a notified body.
• Artificial intelligence - the system's risk classification sets the obligations. See the AI Act article.
• Cybersecurity and the financial sector - if you sell to banks or are an important supplier, see the DORA article.
• A personal data breach - the Commission for Personal Data Protection must be notified within 72 hours of becoming aware of the breach (Art. 33 GDPR). A lawyer is also needed for processing sensitive data, transferring data outside the European Economic Area and automated profiling.

3. When you can do without a lawyer

On your own

Registering an EOOD with one owner. No partners, no internal conflict, low risk. Filing electronically with a qualified electronic signature costs a state fee of roughly EUR 28, or roughly EUR 56 at the counter. The minimum capital is EUR 1. You need the application, the articles of incorporation, the founding decision, the manager's declarations, a notarised specimen of the manager's signature and proof that the capital has been paid in. How to choose the legal form is covered in the corporate structure article.

A standard non-disclosure agreement (NDA) for exploratory talks with a potential partner, when you're not handing over source code or key technology.

A privacy and cookie policy from a generator such as iubenda or Termly (online generators of legal policies) - only for a standard B2B service. A generator is risky if you use marketing pixels or cookies that need a consent management platform, process sensitive data or children's data, profile users or run AI on their data, transfer data outside the EEA, or process data on behalf of your customers.

When a template is enough - and when it isn't

Document	Template?	Why
Handover record	Yes	A standard form that only confirms delivered work or goods.
Letter of intent	With care	Even when headed "non-binding", it can contain binding clauses on confidentiality, exclusivity and governing law.
Terms and conditions on an invoice	With care	They bind the customer only if provided and accepted before or at the time of the deal. With consumers, the bans on unfair terms also apply.
Shareholders' agreement	No	Vesting and the deadlock mechanism need a bespoke document.
Software development contract	No	Without precise clauses the copyright in the code may not pass to you.
Employment contract with clauses on ownership of work	No	It combines the requirements of employment and copyright law.

Which consumer terms are void is set out in the B2C compliance checklist.

When the accountant replaces the lawyer

VAT registration, dealing with the tax authority, publishing the annual financial statements in the Commercial Register and notifying employment contracts are the accountant's job. The deadlines are in the tax calendar.

You need a tax lawyer when:

• you receive an audit report from the tax authority - you have only 14 days to object;
• the structure is international - transfer pricing (prices between related companies in different countries) or double tax treaties;
• there is a dispute over withholding tax - the tax you deduct when paying a foreign person;
• you need to settle the tax treatment of employee options or crypto transactions.

The notary

To transfer shares in an OOD, the law requires a contract with notarial certification of both the signatures and the content at the same time (Art. 129(2) of the Commerce Act). The notary is mandatory, but someone has to have prepared the document the notary certifies. If a founder or investor is abroad, their documents need an apostille (international certification of the document), a translation and sometimes legalisation, which by practice estimates adds one to three weeks. Plan it into the deal timeline.

For a small deal a verbal agreement can be enough, but larger ones need a trail - see what an email or chat is worth as evidence.

4. What kind of lawyer you need

"Lawyer" isn't one profession but at least six. Hiring a good lawyer in the wrong specialism is a common mistake.

Specialism	What it covers	When it's critical
Corporate law	Incorporation, shareholders' agreement, investment, sale of the company	With a new partner or investor
Employment law	Employment contracts, rights in employees' work, disputes, inspections	When hiring and letting people go
Intellectual property	Trademarks, patents, licences, copyright in software	When choosing a name and licensing software
Tax law	Tax structures, challenging audits	In an audit and with a structure abroad
Litigation	Court cases	With a claim, an order for payment or an attachment
Regulatory law	Fintech, crypto, medical software	Before a licence and before launch

A firm or a solo lawyer? Compare specific experience and scope, not the organisational form. Small specialist firms sometimes charge high rates, and some large firms offer fixed packages for startups.

Not in Sofia? Lawyers experienced in startups, venture capital, intellectual property and regulation are concentrated mainly in Sofia. Founders in other cities usually work with them remotely and use a local notary or lawyer for local steps.

5. What it costs and how you pay

Since February 2026 the Bar Act says expressly that the fee is set freely in a contract between lawyer and client. There is no mandatory minimum. The Supreme Bar Council's old ordinance on minimum fees lost its binding force after a judgment of the Court of Justice of the EU in January 2024. Where there is no contract, the fee is set by the bar council using criteria such as the complexity of the case and the interest at stake. The takeaway: agree the fee in writing before work starts.

There are several ways to pay:

• Hourly - you pay for the hours worked. Suits advice and unpredictable negotiations.
• Fixed price - for a clearly defined result, such as an incorporation or a trademark application.
• Monthly retainer - a fixed monthly sum with hours included. Suits the stage when legal questions become regular.
• Hybrid - a fixed price for defined projects and an hourly rate for the unexpected.
• Outcome-based fee - the law allows part of the fee to be a percentage of the interest depending on the outcome of the case, except in criminal cases and civil cases with no monetary value.

Indicative market figures, excluding VAT:

Service	Indicative
An hour with a solo lawyer or small firm	roughly EUR 60 to EUR 130
An hour at a large firm	roughly EUR 155 to EUR 305 or more
A monthly retainer with 5 to 15 hours included	roughly EUR 410 to EUR 1,280
Setting up an OOD with a full shareholders' agreement	roughly EUR 510 to EUR 1,530
A seed round with one investor	roughly EUR 1,530 to EUR 2,560
A seed round with a fund, a SAFE or foreign parties	roughly EUR 3,070 to EUR 6,140 or more

On top come 20% VAT if the lawyer or firm is VAT-registered, plus state and notary fees, translations, apostilles and couriers. Ask in advance which of these are included. Trademark registration fees are in the intellectual property article.

6. How to find the lawyer

A good startup lawyer is rarely found through a search engine. Here's where to start:

• BESCO (the Bulgarian Entrepreneurial Association, founded as the startup association) - a network of founders and events where recommendations get swapped.
• BVCA (the Bulgarian Private Equity and Venture Capital Association, which brings the investment funds together) - its member funds and the advisers they work with.
• The portfolio companies of accelerators and funds such as Eleven Ventures, LAUNCHub Ventures, Innovation Capital, Vitosha Venture Partners and NV3 (Bulgarian venture capital funds) - ask founders who have already been through an investment whom they worked with.
• The bar registers - at bar-register.bg the Supreme Bar Council publishes the unified bar registers. Check there that the person is registered as a lawyer and which bar they belong to.

These organisations are a starting point for your search, not a recommendation of any particular lawyer.

Signals that should send you looking elsewhere:

• refusing to sign a written legal services contract and to issue an invoice;
• vagueness about whether the lawyer is VAT-registered, and silence about state and notary costs;
• no experience with the Commercial Register and the electronic systems of the Registry Agency and the tax authority;
• no conflict-of-interest check at all - that is, whether the lawyer also works for the other side;
• a promise of a "100% guaranteed" outcome in a case or a procedure before an authority.

7. How to work with your lawyer efficiently

The most expensive hour is the one in which the lawyer asks what happened. Send a one-page brief in advance:

1. Facts and timeline - a short history, dates, events.
2. The parties - companies with their registration numbers, individuals, related persons.
3. The goal - what you want to achieve commercially.
4. Red lines - what's essential and what's nice to have.
5. The documents - contracts and emails attached to the brief.
6. Law and venue - Bulgarian or foreign law, court or arbitration.
7. The deadline - a date for the finished document or a procedural deadline.
8. Budget and expected output - an oral view, a written analysis or a draft contract.

8. Alternatives to a traditional lawyer

Online legal services. Clerky (for incorporating and documenting US companies) is built for Delaware companies and doesn't work for a Bulgarian OOD without restructuring into a US company. SeedLegals (a platform for investment and corporate documents) supports the laws of the United Kingdom, France, Ireland and a few other countries. For a Bulgarian company it can serve only as a guide to term sheet structure, and the documents have to be adapted to Bulgarian law by a local lawyer.

Free legal aid. State legal aid is for individuals in hardship. Companies can't receive it, and university law clinics also advise citizens, not companies.

Free registers you can check yourself: EUIPO's TMview and eSearch Plus for similar trademarks, the Commercial Register for a counterparty's current status and managers, the tax authority's portal for VAT numbers, and the registers of the Financial Supervision Commission and the Bulgarian National Bank for licensed payment institutions and crypto service providers.

The EU fund for small and medium-sized enterprises reimburses part of trademark fees if approved before filing, but the programme runs year by year, and in 2026 the trademark vouchers ran out as early as May. Check that it's open before relying on it.

Legal expenses insurance. For small companies in Bulgaria it's offered in a limited form, usually as an add-on to general liability insurance, with low limits and mostly for employment or premises disputes. Don't confuse it with professional indemnity insurance (damage caused to clients), directors' and officers' liability insurance (D&O) or cyber insurance.
