Do I need an owner's license to join a thoroughbred racing partnership

Do I need an owner's license to join a thoroughbred racing partnership?  In general, the answer is 'yes'. There may be exceptions where if you own a small enough share of a horse, you wouldn't need to be licensed, but it's best to assume that you will.  The good news is that the cost (which varies from state to state) is generally quite low...ranging from tens of dollars to a few hundred dollars.  Also, any partnership you're considering joining will be able to provide you with the information you need on licensing, and in most cases they'll be happy to help facilitate this for you.
