FL-115 and e-file

How do I go about filling out the FL-115 if I e-filed the original documents and then served via e-service?

E-service is not valid service absent a formal stipulation and order agreeing to electronic service.

Does this vary by county?

No.

It’s a little confusing on my end since it’s a mandatory e-file in Orange County, but I still must print out everything and get someone to serve the paperwork or mail it?

Service is not the same as filing. Service relates to the other party. Filing is with the court. If you don’t think of them as the same process, it’s not confusing. There are different rules/laws for each.
