I have a child with my ex partner and we are both on the birth certificate.. Can I fight for custody?

The birth certificate does not really mean much when it comes to "custody" (what is now called timesharing). If the child was not born during an intact marriage, you need to file a Petition to Establish Paternity (see form below). http://www.flcourts.org/core/fileparse.php/533/urlt/983a.pdf Best of Luck, Helena Y.
