I've recently been informed by the

You say you sold the property but fogot that this bit was included.  Presumably when you sold it, the  buyers assumed they were buying that piece too?  If so, you leaglly (and morally) cannot ask for money for the piece of land you forgot to include in the original sale.  If on the other hand, that piece of land is entirely separate to what was included in the original sale you can ask market price.     Whoever was your agent for the sale, should be taken to task.   However for the mappa catastale you need to contact someone such as a sbrigapratica, pr the agent who sold your property.  Even the act of sale whcih the notary will have will have the mappa catastaele attached, so you need to ask the notary for a 'copia conforma' of the act which will have all the attachments.

Thank you for your reply. I can only assume that the succession of owners (at least 3) since I left have been unaware that the land was still in my name and have been using it. The current owner says she was surprised to find out at the Notary's at the time of purchase 3 years ago, that the land was still in my name so she must have been led to believe up until then by previous owners or an estate agent that house and land were together. Why any of the previous owners were not told if that were the case that they didn't own the land as well, I can only put down to bad conveyancing. Thank you for your advice.

It is always possible that the land was sold, but the voltura wasnt done at the catasto office.  The act of sale is your deed, not the visura - so its depends what the act of sales say.  the visura is not legal proof, onlny a guide - and its easy to update.
