Seller liability after incorrect information

Questioner

Almost 4 months ago we bought a building, residential/work destination, with a toilet in it. It was known that we were not on the municipal sewer but that there was a septic tank. This was verbally indicated by the seller himself. Now it started to 'smell' very much from the street, so to speak, and because we had to go and look for the septic tank anyway, we hired a company to do this and possibly find out the cause of the stench. Now it turns out, after searching with a camera and sensor, that there is no septic tank at all but that the toilet is directly connected to the rainwater drain. Can we hold the seller liable for this or is that pointless? I would like to hear from you.

Lawyer

In principle, this is possible, but you will have to prove it, since a verbal promise was made. You may be accused by the seller of not having fulfilled your duty to investigate. However, the seller's statements are decisive and may be grounds for recourse. I therefore advise you to hold the seller liable. If you cannot reach an agreement, I would be happy to look at your case.
