It would depend on which religion you are. Presently, you must undergo a six month Marriage counseling course in order to get married.
If you are Catholic then you can get your parish priest to send the documents over to St Lucia to make the necessary arrangements before you get here in St Lucia.
Likewise, if you belong to an other religion then the same applies. If you know what part of St Lucia you want to get married and which denomination, I can assist you to make the contact with the one in St Lucia.
