Under Czech law, contracts can only be terminated unilaterally if statutory or contractual conditions are met. Otherwise, it’s an unlawful withdrawal – and may give rise to damage claims.

When is withdrawal unlawful?

• There is no valid reason (e.g., no material breach of contract)

• The withdrawing party failed to give notice or remedy period

• The form was breached (e.g., agreed written delivery not followed)

• Withdrawal occurred too late – the right had already expired

What to do in such cases?

1. Respond promptly in writing – state that the withdrawal is invalid

2. Secure evidence – emails, records, photos, contracts, logs

3. Calculate your losses – lost profit, materials, labour time

4. Try to resolve amicably – formal legal letter may help

5. Prepare for court – if no solution is found

Typical mistakes

• Silence – may be taken as acceptance

• Vague contract terms – unclear procedures or rights

• Lack of records – difficult to prove proper performance
