the television are not from denmark. origin is poland

In English law and normally used as the general rule where goods are sold by a non-owner then the eventual purchaser does not gain goods title.

This means that if Person 2 wrongly sells goods belonging to Person 1 to a buyer called Person 3, then the goods remain the property of Person 1.

The fact that Person 3 is entirely innocently when he/she purchased goods that he/she believed were owned by Person 2 is irrelevant.

Under English law and I expect it is similar in most EU countries it is the responsibility of the seller to have paperwork that satisfies themselves and others that they are the legal owner of the goods they are selling. If they cannot, then the seller can be arrested for the criminal offence of "Handling Stolen Goods"

i know that law and understand thats why i checked the serial number to see if they are not stolen good. I have the reports to proof it.

It does not matter where you purchased the goods, but it does matter who you purchased the goods from.

If you have purchased the goods from a VAT registered person or company and you have an invoice from that company, then you are the legal owner. If not, then you are almost certainly not the legal owner.

The fact that you have checked the serial numbers does NOT make you the legal owner..

yeah but they are not stolen. and i have an invoices for my purchase.

Do you have an invoice for the goods you are selling from the company or person who sold them to you?

Well, wherever they were bought, there was supposed to be an invoice at the moment of first sales as they were not produced by a private person but rather a VAT registered company. Even if hypothetically B&O sold 20 of them to a private person directly without the dealer involved, there would be this first invoice issued by B&O. 

So if there is no invoice to be shown then unfortunately it is difficult to prove they are legit. Not to mention that I can't even think of a potential customer cashing out 2.000 EUR (give and take 500) for a product with no invoice...

Apologies gents - haven't seen your posts as I was typing mine. :/

Anyway: there is supposed to be either a B&O invoice attached or the one from an authorized B&O Dealer. I wouldn't care much for an invoice from John Doe.
