Thank you very much for help. I also dug myself up, printed it and added it to the case file. As you can see, the amount of this trailer is PLN 7,600, and 2 experts estimated a really hidden defect at 5,000, up to 10,000. This scammer knew it well. I called him with my husband and he replied that we did it ourselves ?. I already had a recorded expert who was to state over which years the defect arose, but the court appoints its expert, so my lawyer said that it was a waste of money.
