My situation is, I never got a divorce from someone I was married to briefly, (about 15 months) back in 1994-5. So somewhere out there I have an estranged husband,and haven't a clue where he is,nor do I care. I have heard you can get a divorce by doing it yourself (less money than a lawyer), there is no children involved, no house, no money, etc. I just want a legal divorce. Can I do this myself, where do I start? Any advice would be appreciated. Thanks

... where do I start?...

At the courthouse (state, or county not federal- I assume you are in the U.S.). Ask the clerk of court if there are do-it-yourself forms. Or check the court's website.
