Can I fill out separation papers without husband

Because I do not know of his whereabout?

I would like to fill out separation papers
But I do not know his whereabouts
Can I file my own papers?

Please pay more attention to posting guidelines. There is a Read First sticky in the Divorce forum (where this was moved from) that directs questions of a legal nature to this forum.

You can fill out the separation papers and file them. You will have to show a good faith effort to serve him notice. What that means depends on your location.
