I live in Florida and have received papers for child support from Puerto Rico. Do I need a lawyer in Puerto Rico? or can I use a lawyer in Florida?

It depends what "kind" of "papers" you received.  Typically, at least under Florida law,  an action for child support would have to be brought against you in the state you reside.  However, if you have prior contacts with Puerto Rico (ie: you previously lived there, own a business there or property) it may be the propoer place for the case to be situated.  Since there is something pending in Puerto Rico at this time, I suggest you contact an attorney there, explain the situation and then if Puerto RIco is the improper jurisdiction that Puerto Rican attorney can file the proper motion to dismiss or transfer the action.
