Fief Exchange

To support consolidating your properties you may now negotiate with other vassals to trade fiefs. You can suggest a trade with any other vassal of your faction and if you're a ruler then you may negotiate a trade between two vassals of your realm. Vassals will not accept just any trade though and will be picky about getting a good deal.

These are the offering types available for you to trade with. They can be selected by clicking the drop-down menu next to an "Offering:" label on your side. You will also need to setup what you're asking the other vassal to offer to complete the trade as they will not suggest their own trades at this time.

In any trade arrangement a "Make Offer" button will be available at the bottom of the left side of the screen. When choosing to make an offer several things are taken account in order for one to be successful:
 * There must be some form of land in the trade. At least one fief must be offered on either side.
 * In an AI vs. Player trade the AI will expect their rating to be less than the players to represent them getting a better deal.
 * A vassal will not accept any trade that will cause them to drop in title. For example, they will not give up their only castle in exchange for any number of villages.
 * Each side must offer something in trade.

A ruler visiting this interface will have a further option to "Force Exchange" and while this bypasses many of the objections a vassal may have to a trade it will have diplomatic consequences. A vassal being given the better side of a trade will gain in relation with the ruler, while the one being slighted will lose relation. These relationship changes are further spread amongst that vassal's family members so a heavily one-sided trade can have severe consequences with one family while improving influence with another. The minimum requirements to enforce a trade include:
 * There must be some form of land in the trade. At least one fief must be offered on either side.
 * Each side must offer something in trade.

NOTE: Once the final rating is achieved this is further enhanced by your Persuasion and Trade skills by increasing your rating 0.8% per rank in either skill.
