Need Quick response!

I filed for custody on May 29th
He filed for custody on June 3rd

I have no attorney, he does. He filed a response, but I am under the impression that the two cases will be combined making me the plaintiff.

Do I still need to file a response? and how do I do so with no attorney. I simply can not afford one.

You should respond to his complaint by asking that the cases be consolidated under your file number as you filed first.
