Hello, My husband walked out on us about 10 years ago, I never thought I would meet any one new but I have and now we want to marry each other. However I am still married to the man that left me and my daughter. How do I file for abondenment and get divorced from him to marry my true love?

The question is not how to file for abandonment but to file for divorce. You may need to use abandonment as a grounds for the divorce, but you don't file for abandonment.

The simple answer is consult and hire a divorce lawyer. They will prepare the divorce petition and make sure that a reasonable attempt will be made to contact your ex.
