If you are in the process of selling your horse, congratulations on finding this site. I am trying to put together information that would be helpful to people in general.
Might I suggest you use this site in the following way; find the topic along the top row of the chart on the home page, then view each page in order beneath the topic. This will help you go through the process step-by-step. You can also read them in order by viewing them on the drop-down list on the tabs.
Whatever you do, please know that all information on here is generally meant to be informative, and in no way am I demanding anything from you. Knowledge is power.
