My son's mother refuses to let me see our son. What do I have to do to get my visitation rights and/or shared custody?

You need a court order establishing visitation.

You need to go to Court and file a petition to enforce your contact rights with your son. In Florida, last year the law eliminated the word "visitation" and now is called a "parenting schedule/contact plan". So, once you file the suit in Court, there is a process to be followed through the final end, which is a signed court order by a judge reflecting the dates, times, and places, where you will have contact/visitation with your son. Mind you, even after you have this order, she may still behave the same way, and you may have to bring her back to court after you obtain the order to "enforce it". There are some enforcement methods to follow after that.

You need to file a petition for paternity as I assume you were never married based on your question. You should also file a motion for temporary relief and request a timesharing schedule with your son.
