My question involves malpractice by a lawyer in the state of: Georgia

My wife was in car accident almost 2 years while pregant for our first child. It was the fault of the other. We decided to sue her so we went with a lawyer that her sister was working for at the time. We waited and waited for him to wrap up the case. Every time we called him he would say he was getting all the paperwork together and not to worry about anything. He finally told us that everything was together and he was waiting on a response for the amount he was sueing for. Once again we waited (keep in mind this dragged on for 2 years). A couple of weeks ago wife got a call from him saying he was doing personal injury cases anymore and he going to get us another lawyer or we could use our own. He said that he was doing social security cases because it was easy money. Two days ago we got a letter from the defendants lawyer saying they filed for a dismiss of the case and the court date was on Sept. 9th. My wife went to our new lawyer and gave him the file from the other lawyer. The new lawyer proceeded to tell my wife that the old lawyer never served the defendant with the papers. Apparently he tried to serve them at her parents house but she didn't reside there so the paper were never served. I guess he was to lazy to find her. Keep in mind we are just finding out about this 2 years later. The new lawyer said that the "staute of limitations" had run out to serve the papers. On top of that the reason he didn't want to do the case was he has been suspended by the bar for malpractice.

My question is should my wife go to court and try to explain to the judge what has happened and try to get a continous in the case?

Can we sue him for malpractice or is not worth it?
