The Land Registry is a state department, where you can manage your real estate. There are two ways to transfer your rent rights to another account.
The first one is a land auction: you set a start price and the auction lasts for 24 hours. The auction time will be extended for 3 minutes whenever a new bid is submitted during the last 3 min of the auction. The plot goes to the account which bids the highest price. Anyone can take part, as long as your account has enough gold to make a bid. When the auction is finished, the buyer or seller should finalize the transfer by pressing the button. The plot will be sold with all property which is on the plot at the moment of the auction start. During the auction, the current plot will be blocked, and you will have no right to take any actions on the plot. Make sure to remove property before starting the auction if you don't want it included.
You need to click the "Auction" button and in the next window write the price and "Create" an application.
You can also see all the land currently up for auction in the "Land Registry" tab.
The other way to transfer a plot, is to sell/pass the rent rights to a specific account. In this case, you send a proposal to the selected account. You have to set the price if you want to sell the plot. You can also enter a price of “zero” if you want to pass this plot to the chosen person for free. To finalize this transfer, the account has to accept your proposal. You will be able to look over any proposals that anyone has sent you in the Land Registry window. You will have the option to accept or delete them.
In either case, pay attention to the contents on your plot. All the property, including anything in the storage, will be sold the moment you confirm your action of selling/passing the plot at the end of the auction. If you want to keep something make sure to move it off the plot.
You need to click the "Pass on" button, then write the account name of the new owner and the price of your deal. The new owner must confirm your deal in his account.
