In the day-to-day operation of a company, you need a lawyer within easy reach—sometimes for a quick consultation, other times to address unexpected legal issues. A flat-fee arrangement with a Prague-based law firm makes this possible for a pre-agreed monthly amount. It sounds simple, but in practice there are far more details involved than most entrepreneurs realize. In this article, you will learn how to set the terms of such cooperation correctly so that it is beneficial and efficient for both parties—and, above all, so that it saves you both time and money.

Quick summary

  • A flat-fee model means predictable costs: For a fixed monthly amount, you are guaranteed access to legal advice within an agreed number of hours, making funding more transparent and easier to plan in a corporate budget than an hourly rate.
  • Defining the scope is essential: The agreement must clearly define what is included in the flat fee (day-to-day matters, consultations, contract reviews) and what is handled separately (e.g., litigation, complex M&A transactions); otherwise, disputes and hidden costs may arise.
  • The quality of communication determines success: An attorney who responds promptly and understands your business situation becomes an invaluable partner; conversely, poor communication can lead to unnecessary waste of time and money even under a flat fee.
  • A notice period protects both parties: Clear rules for terminating the cooperation (typically 1–3 months) and settlement mechanisms ensure that no one can be “trapped” in an unsuitable agreement.

Why consider a flat-fee arrangement with a law firm in Prague at all?

Entrepreneurs often choose between three options: hiring an in-house lawyer, outsourcing individual matters to attorneys on an hourly basis (ad hoc), or entering into a flat-fee arrangement. Each option has its place, but the flat-fee model is particularly popular with small and medium-sized businesses due to efficiency and predictable costs.

The main advantage of a flat fee is that you do not have to watch the clock on every call and worry about an invoice for a short phone consultation. The attorney, in turn, knows how much work to reserve each month for the client and can plan the team’s capacity more efficiently. This mutual certainty forms the basis of a well-functioning cooperation.

What exactly is a flat-fee arrangement and what options are available?

A flat-fee arrangement with a law firm in Prague (an agreement for the provision of legal services for a flat fee) means you contractually agree on a fixed monthly fee for legal services within a certain scope. Instead of employing your own lawyer (which entails high salary costs, mandatory contributions, and administration), you gain access to an external team of specialists.

In Czech legal practice, there are three basic variants of flat-fee cooperation.

  • First option – comprehensive flat fee: The law firm in Prague provides your company’s complete day-to-day legal agenda within an agreed scope—typically from 5 to 20 hours per month. Everything that fits within these hours and relates to the ordinary running of the business is included. This means consultations, drafting and reviewing commercial contracts, corporate matters, legislative monitoring, or legal support for operational decision-making.
  • Second option – the attorneys handle only a defined part of your agenda—for example, receivables management, employment law matters under Czech legislation, or compliance. You handle other matters yourself or ad hoc. Litigation or specific projects are usually billed separately in this case.
  • Third option – retainer model: A monthly flat fee (often lower) guarantees you priority access to an attorney and basic on-call availability, while specific tasks are billed either on top of this fee, or the flat fee functions as a prepaid credit from which hours are deducted.

ARROWS attorneys in Prague routinely work with all of these models and can advise you on which option will be most efficient for your company in 2026.

Related questions on flat-fee cooperation

1. Which flat-fee option is best for a smaller company?
Most often, a comprehensive flat fee with a lower number of hours (e.g., 5–10 per month) works best. The retainer model is more suitable for companies that need a guaranteed immediate response in crisis situations.

2. Can I change the flat-fee scope during the year?
Yes—this is usually done by a written amendment to the agreement, effective from the following month. A well-drafted agreement should allow for flexibility, enabling you to increase the scope as the company grows or reduce it if the workload decreases.

3. What happens if I exceed the agreed number of hours?
This must be clearly stated in the agreement. Typically, hours exceeding the flat fee are billed at a discounted hourly rate (compared to the standard rate), or the flat fee is increased if the overrun is long-term. It should never come as a surprise only when you receive the invoice.

How to properly define the scope of services in a flat-fee agreement?

This is where the most common source of problems lies. Both parties think they understand each other, but their expectations differ. The attorney assumes the flat fee covers only minor consultations, while the client expects court representation to be included in the price. The agreement for the provision of legal services must contain a precise list of what is and is not included.

A recommended structure for 2026 looks like this:

What is MOSTLY included in the flat fee:

  • Telephone consultations and email correspondence.
  • Legal advice on routine commercial questions.
  • Drafting and review of standard contracts (purchase agreements, contracts for work, lease agreements, employment contracts).
  • Filing changes in  (changes of managing directors, registered office).
  • Monitoring of legislation relevant to the client’s business sector.
  • Communication with authorities in administrative proceedings (in routine matters).

What is NOT included in the flat fee and is billed separately (unless agreed otherwise):

  • Court disputes and representation in proceedings before courts (fees here are often governed by the Czech attorney tariff or a special rate).
  • Large-scale transactions such as Mergers and Acquisitions (M&A).
  • Criminal defence.
  • Specific tax advice (if the firm does not have its own tax advisers).
  • Direct costs (court and administrative fees, notarial fees, travel expenses outside the attorney’s office location).

ARROWS attorneys in Prague note that working with this definition eliminates the vast majority of misunderstandings. At the same time, the time allocation must also be clearly defined—how much time is to be available each month. Every started quarter-hour or hour should be recorded.

Related questions on defining the scope

1. What should I do if it is not clear whether a matter is covered by the retainer?
A well-drafted agreement includes the attorney’s obligation to notify the client in advance if the requested task falls outside the retainer or would significantly exceed it, and to obtain consent to bill for “additional work”.

2. Can I “try” the retainer for a month with no commitment?
Yes, it is possible to agree on an open-ended engagement with a short notice period from the outset, or a “trial period” at the standard hourly rate, which is converted to a retainer after one month.

3. What if I take a retainer and during the year find that I need more services?
The agreement can be amended by an addendum. Increasing the retainer (an upgrade) is usually a welcome step for a Prague-based law firm and should not be an issue.

What should the contractual arrangement look like and what must not be missing?

The relationship between an attorney and a client is governed by the Act on the Legal Profession and the Civil Code (mandate agreement) under Czech law. Without a high-quality written document, you risk disputes. A retainer agreement must include at least the following elements:

  • Contracting parties – clear identification of the law firm in Prague and your company.
  • Subject matter and scope of services – precise specification of the agenda and the time allocation.
  • Fee and payment terms – the amount of the retainer, due date, whether the amount is inclusive or exclusive of VAT (in 2026, the standard VAT rate for legal services is 21%).
  • Fees for services beyond the retainer – what rate is charged after the hours are used up? (e.g., CZK 2,000–3,500/hour + VAT depending on the lawyer’s seniority).
  • Reporting – the attorney’s obligation to provide an overview of recorded work (specification of services provided) so that you have control over the use of the retainer.
  • Term and termination – a fixed-term or open-ended agreement and the notice period. The standard is 1–3 months.
  • Obligations upon termination – under the Act on the Legal Profession, the attorney is obliged for 15 days after termination of representation to take urgent actions so that the client does not suffer harm (unless agreed otherwise).
  • Conflict of interest – provisions on how the firm proceeds if a conflict of interest is identified (e.g., if it were to represent the opposing party). A professional firm must have control mechanisms in place.
  • Professional liability insurance – an attorney is liable for damage caused in the course of practising law. Make sure the insurance limit is sufficient for the size of your business. ARROWS advokátní kancelář has insurance with a limit of CZK 400 million, which significantly exceeds the statutory minimum.
Related questions on contractual arrangements

1. What happens to a matter in progress if we terminate the agreement?
The attorney must hand over all materials and the case file documentation to you. You then arrange completion of the matter with a new legal representative.

2. Does the retainer transfer upon the sale of a company?
If the agreement is concluded with a legal entity (s.r.o.) and there is a transfer of a business share (share deal), the agreement with the attorney continues (the client is still the same s.r.o.). In the case of a sale of an enterprise (asset deal), the agreement does not transfer automatically unless it is assigned with the consent of all parties.

3. What are typical mistakes in agreements?
Absence of a mechanism to control time reporting, an unclear definition of “additional work”, and missing rules for annual indexation of the price for inflation.

Financial set-up – how much does a retainer cost and how is it paid?

The retainer price reflects expertise, the scope of responsibility, and time demands. In 2026, the prices of quality legal services in the Czech Republic typically fall within the following indicative ranges:

Basic retainer (5–8 hours per month): approx. CZK 12,000–20,000 per month + VAT.
Standard corporate retainer (10–20 hours per month): approx. CZK 25,000–50,000 per month + VAT.
Intensive retainer (30 or more hours per month): CZK 60,000 and more + VAT.

Amounts vary by region and specialisation. The monthly retainer is usually paid based on an invoice issued either in advance (at the beginning of the month), which is more common for smaller retainers, or in arrears (after the end of the month) together with the settlement of any additional work.

As a standard rule, unused hours are not carried over to the next month, because the attorney reserved capacity for you that could not be sold to another client. Some firms, however, allow a transfer of, for example, 50% of unused hours to the following month, or operate on a “credit” basis.

Exceeding the retainer is invoiced at the rate agreed in the agreement. It is a good idea to set up notifications—for example, once you have used 80% of the retainer, the attorney informs you by email.

Quality of communication – the key to successful cooperation

A technically correct agreement is only the beginning. In practice, satisfaction depends on the “chemistry” and the communication set-up. Under a retainer, the response time should be guaranteed. If you wait a week for an answer, the retainer loses its point. The standard is acknowledgement of receipt of the request within 24 hours and commencement of work within 48 hours.

A lawyer should speak the language of your business, not merely quote statutory provisions. ARROWS lawyers are guided to provide clients with practical solutions, not just theoretical analyses.

Communication also includes regularity. You should receive a monthly report summarising what has been done and have regular status updates or short meetings on priorities for the next period. The attorney–client relationship is based on trust and the duty of confidentiality, which is statutory for attorneys and very strict under Czech law.

What risks you face and how ARROWS advokátní kancelář can help

Risks

How ARROWS helps (office@arws.cz)

Unclear scope of services: Disputes over whether a task is paid within the retainer or as an extra.

Precise agreement: Together, we will define a clear catalogue of services included in the retainer and those outside it to prevent misunderstandings.

Unexpected surcharges: Exceeding hours without the client’s knowledge.

Usage notifications: We will notify you when you are approaching the limit of the retainer so you can decide on the next steps.

Non-terminability: A long-term agreement without the option to terminate.

Fair terms: A standard notice period that gives both parties freedom if the cooperation does not suit them.

Lack of transparency: You do not know what the lawyer did all month.

Detailed reporting: Each month you will receive an overview of the work performed.

Conflict of interest: The attorney represents your competitor in a related matter.

Conflict-of-interest screening: We have a sophisticated system to check for conflicts of interest even before taking on a matter.

How the process works from first contact to signing the agreement

Choosing a partner for a retainer requires care. Here is the recommended process:

  • Step 1: Needs analysis – clarify which legal issues you deal with repeatedly and what your budget is.
  • Step 2: References and verification – verify the registration in the list of attorneys maintained by the Czech Bar Association (ČAK). Find out the firm’s area of specialization. ARROWS advokátní kancelář has experience with clients ranging from startups to large corporations.
  • Step 3: Introductory meeting – it should be non-binding. Find out whether you and the attorney are a good personal fit and whether they understand your business model.
  • Step 4: Cooperation proposal – the Prague-based law firm will prepare a draft agreement defining the scope and price. Do not be afraid to negotiate the terms.
  • Step 5: Signing and onboarding – after signing the agreement, the documents will be handed over, communication channels will be set up, and, if applicable, a power of attorney for representation will be granted.
  • Step 6: Trial period – the first 1–3 months serve to fine-tune the cooperation.

How to address issues if the cooperation is not working

If you are not satisfied (e.g., with speed or the quality of deliverables), address it immediately. Communication is key, so contact the firm’s responsible partner. Most issues can be resolved by adjusting the setup or replacing a specific attorney within the firm’s team. You also have the right to make a complaint about the service if it does not correspond to what was agreed.

If a remedy is not possible, use the notice period. The attorney is obliged to hand over your file and cooperate in transferring the matter to a new representative. Disputes between an attorney and a consumer can be resolved out of court through the Czech Bar Association; in B2B relationships, they are then handled via the standard route.

International element – when you need a lawyer abroad

If your business extends beyond the borders of the Czech Republic, a local retainer may not be sufficient. The ARROWS International network makes it possible to handle legal matters efficiently in many countries worldwide through a single point of contact in the Czech Republic. This way, you do not have to search for lawyers in each country separately and negotiate terms in a complicated way – the Prague-based law firm coordinates the approach with foreign colleagues.

Conclusion

A retainer arrangement with a Prague-based law firm is a modern tool for managing a company’s legal risks. The key to success is a properly structured agreement, transparent reporting, and mutual trust.

Main points to remember:

  • A retainer brings financial stability and priority access.
  • The scope of services must be precisely defined in the agreement.
  • Do not be afraid to request work reports.
  • A high-quality Prague-based law firm is insured and acts transparently.

FAQ – Most common questions about retainer cooperation

1. Is a retainer always more advantageous than an hourly rate?
If you have regular legal work (at least a few hours per month), then yes – the effective hourly rate within a retainer is usually lower than the standard “ad hoc” rate. For one-off matters, it may be better to agree a fixed fee per task or project.

2. Can a retainer also be provided by a sole attorney?
Yes. However, the advantage of a law firm (a team) is substitutability – if one attorney falls ill or is on vacation, a colleague can step in, which cannot be guaranteed by an individual.

3. What is the notice period?
It depends on the agreement; typically 1 to 3 months. The Czech Advocacy Act allows the client to terminate the legal services agreement at any time (with immediate effect or as agreed), while the attorney has more limited termination options. In B2B retainers, a contractual notice period for both parties is often agreed.

4. What if I need a lawyer on the weekend?
A standard retainer covers business days. If you require 24/7 availability or weekend coverage, a special arrangement must be agreed (a higher retainer or surcharges).

5. Can private matters of the company owner also be handled under the retainer?
Yes, if agreed in the contract and the invoicing complies with tax regulations (note the tax deductibility of company costs relating to the shareholder’s private matters).

6. Can I adjust the retainer during the year?
Yes, flexibility is one of the advantages. Contact office@arws.cz to set up a tailored model.
