In contrast to oral agreement — during which often later Statement versus statement stands — does a written contract offer significantly more security. All parties can review the agreements made at any time, and in the event of a dispute, the document serves as important proof. In this introduction For entrepreneurs, we explain why written agreements are so important, what exactly they mean and what content should not be missing from them. We also provide practical tips on how to draw up a legally secure written agreement.
What is a written agreement?
One written agreement is basically nothing more than a contract that is recorded in text form and signed by the parties involved. It documents an agreement between two or more parties and makes the terms understandable and binding for everyone. From a legal point of view, a written agreement has the same meaning as an oral contract — with the difference that all points are written down explicitly. This provides clarity about the content of the contract and makes it easier to enforce the agreed rights and obligations.
Distinction from other types of contract: Contracts can be concluded in various ways — orally, in writing or even implied (through coherent action). In principle, there is freedom of contract and freedom of form in Germany: A handshake or a verbal commitment can establish a valid contract. However, oral agreements lack clear documentation. A written agreement offers significantly more evidentiary security and formality. It is less complex than, for example, a notarized contract (which is mandatory for real estate purchases, for example), but more formal and reliable than a mere oral “gentlemen's agreement.”
Examples of typical use cases: In business practice, many contracts are concluded in writing. Typical written agreements include: a business contract with a customer or supplier (for example through project collaboration or delivery of goods), a lease about office space, a cooperation agreement between two companies, one employment contract with a new employee or a Confidentiality Agreement (NDA) to protect sensitive information. In all these cases, a written contract ensures that both parties know exactly where they stand and what is expected of them
When is a written agreement required or useful?
Statutory requirements: In some cases, the written form is not only recommended, but even required by law. Specific contracts must are concluded in writing in accordance with the law — for example employment contracts, terminations, rental agreements or guarantees. This means that without a signature on paper (or digital signature with appropriate qualification), such agreements are ineffective. The legislator requires the written form in particular for agreements with a large scope or special need for protection in order to ensure clarity and certainty of evidence. For example, if you hire an employee for a limited period of time or provide a guarantee, the written form is essential.

Benefits of writing: Even if the law does not expressly require a written form, in practice it is often very usefulto record important agreements in writing. Some key benefits of a written agreement include:
- Clarity and clarity: All contract terms — from services to prices to dates — are defined in black and white. This prevents misunderstandings, as both sides have the same text and were able to check it before signing.
- Provability: If discrepancies or even legal disputes arise later on, the written contract serves as evidence. It documents what was actually agreed upon and can be presented in court. Without written documentation, it is much more difficult to prove the content of the contract.
- Commitment and seriousness: A written contract signals that both parties are serious and feel bound by the agreements. This creates trust on both sides. In addition, when drafting in writing, you think more carefully about what you agree on — vague wording or open points are more likely to be noticed and can be clarified.
- Protection against later changes: A written contract often contains a clause that changes must be made in writing (a so-called Written form clause). This prevents a party from invoking any informal ancillary agreement that is not in the contract. Everything relevant remains comprehensible in the document.
Risks of an oral agreement: In theory, oral agreements are in many cases just as legally valid as written ones — they are just more difficult prove. If there is no written documentation, the burden of proof is borne by the disadvantaged party in the event of a dispute. In court, there is often a case of testimony against statement. Practice shows: Anyone who invokes an oral commitment that is beneficial to him, has bad cards Because without written proof, this agreement usually cannot be proven to convince the court.
In other words, in case of doubt, a claim arising from a mere oral agreement will hardly be enforceable. This risk can have serious consequences — from loss of claims to expensive legal disputes that could have been avoided with a simple document.
In short, whenever important or valuable agreements are involved, you should draw up a written agreement as a security measure. You benefit from clearly regulated circumstances and minimize the risk of problems caused by different memories or interpretations.
Key contents of a written agreement
When drawing up a written agreement, there are certain Core content, which should not be missing in any contract. These points ensure that the agreement is complete and understandable

- Contracting partner: Name all parties involved with their full names and addresses. Companies should also state their legal form and authorized representative. It is important to clearly identify the contract partners so that it is clear who bears the rights and obligations under the contract.
- Subject of contract: Describe precisely what the agreement is about. Which subject or which power Is it being replaced? For example: “Company A is committed to delivering Software X to Company B” or “Person Y rents out office space in Musterstraße 1 to person Z”. The more specifically the subject matter of the contract is defined, the less room remains for interpretation.
- Services & duties: Determine who what when has work to do. What services does one party provide and what does the other provide in return? This includes all obligations of both parties. For example: Delivery times, quality standards, acceptance obligations, cooperation obligations of the customer or certain rules of conduct. It is important to clearly break down which party assumes which obligations so that everyone knows what is expected of them.
- Payment modalities: If the agreement involves payments (such as in the case of sales or service contracts), the price and payment terms should be clearly regulated. This includes the prize or the remuneration, due dates (payment deadlines), the payment method (bank transfer, direct debit, etc.) and, if applicable, conditions such as discounts, down payments or interest on late payment. This will avoid disputes over when and how much must be paid.
- Duration & termination: Determine How long the agreement should apply and under what circumstances it can be terminated. Is the contract limited (up to a specific date or event) or indefinite? If indefinite, are there any notice periods? Determine with which advance notice and in which form (in writing, by registered letter, etc.) a termination must be made. In the case of fixed-term contracts, it may also be regulated whether a prolongation is automatic or not. A clear termination policy protects both sides and ensures that no one is unexpectedly forced out of the agreement or remains bound indefinitely.
- Liability & warranty: Determine who is liable in the event of damage and to what extent. Especially in the case of business agreements, it makes sense to determine what damages a party will pay for, whether liability is limited (for example to the amount of the order value) or whether certain liability cases are excluded. The same applies to warranty in the event of defects: If, for example, a delivered product has defects, for how long and in what form is the supplier liable for them? Such clauses provide clarity about how risks are distributed and can prevent expensive disputes in retrospect.
- Other regulations: This includes all additional agreements that are important to the parties. A written agreement often includes, for example, a Confidentiality clause (Confidentiality of confidential information), particularly when sensitive data or trade secrets are exchanged. Auch Non-competition clauses or Exclusivity agreements May be relevant if the parties want something like that. It is also common to agree on Dispute resolution — for example, choosing the place of jurisdiction (which court should have local jurisdiction if there is a lawsuit) or the agreement on a Arbitral tribunalOr one mediationto resolve disputes out of court. These “other” Clauses round off the contract and cover areas that go beyond the immediate performance and payment aspect.
- Signatures: To conclude the agreement, all parties must Sign legally. The signature (with date and location) documents that each party agrees with the content and wants to commit to it. Without a signature, the document is usually just a draft in the legal sense. Make sure that each contracting party receives a copy. If required, a written agreement can also Digitally signed Become (with a qualified electronic signature), which is equivalent to a handwritten signature — in any case, it is important that it is clearly visible who has signed.
These contents form the basis of every written agreement. Depending on the type of contract, there may of course be other specific points — but the elements mentioned above should always be covered in order to obtain a comprehensive and clear contract.
Tips for a legally secure written agreement
Drafting a written agreement is not rocket science.

With the following practical tips, you can ensure that your contract understandable and legally secure Wants to:
- Clear, understandable wording: Write in such a way that a third party outside the industry could also understand the contract. Avoid unnecessary jargon or nested sentences. If necessary, define important terms directly in the contract. For example: If you use abbreviations or technical terms in the contract, explain them briefly. Clear language helps everyone involved and reduces the risk of different interpretations.
- Completeness — Nothing Just Agreed Verbally: Make sure that all Agreements are recorded in writing. Details are often discussed orally or by e-mail — such points are also included in the contract or at least as an attachment. Don't rely on memory or “That'll be clear.” What is not in the contract is difficult to claim later. Therefore: It is better to take up every important point than to discover gaps afterwards.
- Don't forget important clauses: Some standard clauses increase the legal security of your agreement. One example is the Salvatory clause, which states that the rest of the contract remains valid even if individual provisions should be ineffective. In this way, you prevent the entire contract from becoming invalid just because one point is legally problematic. An already mentioned one is also useful Written form clause — i.e. the notice that changes or additions to the contract must be made in writing. In this way, you avoid discussions about alleged oral ancillary agreements. You can usually adopt these clauses from tried and tested models.
- When in doubt, seek expert advice: If the contract is complex or greater values are at stake, don't be afraid to get a solicitor Let them look over it. Lawyers can make wording legally watertight and know what needs to be considered (for example when it comes to limitations of liability or current legal requirements). Alternatively, there is also Contract management software or Sample contract templatesFor common agreements that help you think of all important points. Use such tools if you are unsure — it's cheaper than risking a lawsuit over a poorly drafted contract.
With these tips, you can ensure that your written agreement is not only formally correct, but also clear and fair for all parties. In the end, every contract is only as good as its content and comprehensibility — so invest a little effort in drafting it, it pays off.
