How do know if wife filed for divorce?

Call the district clerk in the county in which your wife resides. They can tell you. If your wife knows where you are, she cannot, without committing fraud, prove up a final divorce without serving you with the petition.

You will be served with the papers at home or work or someone they can locate you, or you may recevie them via certified mail. If you want to know before that happens, you can go to www.oscn.net and use the court records link to search for her name or your name in the appropriate county database. A divorce will be filed in her county of residence. If you believe divorce is a certainty for your life, it is not too early to see counsel to represent your interests.
