Sell \u200b\u200bpart of the land

I owned a rather large land plot (12 acres), but I don't need one so much earth, I would like to sell part of the neighbors. Where should I contact for making a deal?

A, the law allows selling a part of the land plot. You should divide your site and make a cadastral passport for each part, and then apply to the Office of the Federal Registration Service. The management also needs to provide cadastral passports to newly formed land plots and a sales contract for one of these sites.
