The goal of any negotiation is to find a way to reach an agreement with  the other side of the table. 

The challenge that we run into during this  process is that no matter what negotiation styles or negotiating  techniques are being used we need to understand what the other side  wants and the only way that we can get that information is if they tell  us. However, sometimes we run into situations where the other side is  not telling us the truth – they lie. When we find  ourselves in these situations, it’s going to be even more of a challenge  to reach an agreement with the other side. 

We need to know what action  to take based on what kind of lies are being told.
