ditto Nick and James, you need to be at the notaires and sign or sign a procuration to have your name taken off the title, it can't just be taken off by a third party without your say so! Best touch base with your notaire ;-)
As far as I am aware, the transfer or removal of title will effectively be the same transaction as if you were selling the land to someone else and will entail the usual searches/conveyancing etc. I will happily stand corrected though! I would ask your local Notaire, he/she should be able to advise you without charge.
