How can you protect your civil rights in the event of a violation...?

The first thing you need is to apply in writing to the counterparty with a demand for compensation for damages, justifying the demand with reference to a specific clause of the contract and/or article of the law.

This must be done because, in accordance with clause 6, part 3, article 175 of the Civil Code, the statement of claim must contain information on taking measures for pre-trial settlement of the dispute, if such were carried out, including, if the mandatory pre-trial dispute settlement procedure is defined by law.

In the future, if the counterparty illegally refuses to compensate you for damages, they will file a claim with the court, in which it will be necessary to justify their claims and provide relevant evidence.

The requirements for a claim statement are defined in Article 175 of the Civil Code of Ukraine - https://zakon.rada.gov.ua/laws/show/1618-15/conv#n7328
