Legal Question in Civil Litigation in Georgia

If there is something you can do, which generally is unlikely, no one her can tell you what it is because we certainly don't know anything about the case. There is no general answer to get a new trial on a default. The one near-certain response is that if service was proper and you just ignored the lawsuit, you'll be out of luck. If you want a meaningful response, see a lawyer to actually review the facts.

You didn't say why the company won a default judgment. Also, you didn't say why you waited three years to seek to overturn the judgment. Normally, if service is proper and a defendant simply ignores the complaint and summons (without substantial justification), it is unlikely the court will reopen the matter.

If you were the victim of sewer service (the defendant's process servicer lies about service), you might be successful in opening the matter if you didn't sit on your rights.

You should take all paperwork you have on the matter to an attorney to obtain advise on your rights.
