Finding property owner

Does anyone know the procedure for finding out who owns a particular property.

There is a house in our village that we are interested in which has been empty since we moved there

and we would like to contact the owners.

You don't say why you are interested in this house. If you are looking to buy it and it has been left empty for some time this is an indication that there are multiple inheriteurs who cannot agree.

But the Mairie is the place to start.

Very easy for the Mairie to do. Our cadastre is all on computer. I needed to confirm who was the owner of a field adjoining our garden as I thought I might need to cross his property to shift a digger and some materials into our property. All sorted in five minutes.

Simply go to the mairie and enquire, carefully explaining what you have in mind.
