In a lawsuit, everything revolves around evidence. The court does not decide solely on the basis of stories, but primarily on the basis of facts that can be substantiated. Many individuals underestimate the importance of evidence or do not know which means they may use. In this article, we explain what types of evidence exist, how you can collect evidence and how the court weighs evidence.
Why is evidence so important?
The court must establish what exactly happened. A simple rule applies: whoever asserts something must also prove it.
Do you want to prove that you paid the rent? Then you must present proof of payment.
Do you want to defend against a claim? Then you must submit documents or witnesses that support your account.
Without evidence, you run a significant risk that the court will follow the opposing party's claim.
Types of evidence in a lawsuit
The law recognises various types of evidence. In many cases, the principle of free evidence applies, meaning that almost anything can serve as evidence, provided it is reliable.
1. Written evidence
Contracts and agreements
Invoices and bank statements
Letters, emails or WhatsApp messages
2. Witness statements
People who were present during appointments or events can be heard.
A witness statement can be given orally before the court or in writing.
3. Expert evidence
Reports from experts, for example a medical specialist or building surveyor.
Often used in technical or complex disputes.
4. Photographs, videos and audio recordings
Images or recordings can be a powerful form of evidence.
Be mindful of the rules regarding privacy and legality.
5. Personal statement
Your own statement may play a role, but it generally carries less weight than independent evidence.
How do you collect evidence?

Never discard letters, emails or invoices. Everything may prove relevant later.Make copies and printouts
Organise your evidence in clearly arranged files.Record events
Keep a log of appointments, telephone conversations or incidents.Arrange witnesses in time
Speak with people who can confirm your account and record their details.Involve your lawyer
Your lawyer knows which evidence can be decisive and how best to present it.
How does the court assess evidence?
The court considers the reliability and consistency of the evidence.
Written documents often carry significant weight, especially if signed by both parties.
Witnesses can be persuasive, but they must be credible and not contradict each other.
Sometimes the court orders a party to provide further evidence.
Practical examples
Example 1 (rent): A tenant claimed he had paid in cash but had no proof. The court upheld the landlord's claim.
Example 2 (employment): An employee claimed overtime. Thanks to WhatsApp messages in which the employer gave instructions outside working hours, his claim was upheld.
Example 3 (personal injury): A victim was awarded compensation because a medical expert confirmed his complaints.
