I am sorry to learn about this matter.
Unfortunately, civil litigation moves very slowly - and a 4 year case is not unusual.
However, dealing with specific issues that have caused your case to go for a long period of time are probably best resolved by speaking with a local attorney - someone that you can discuss your case with in detail, and that can review your filings, motion papers, and have an attorney/client relationship with regarding the merits of your case, and develop a strategy to move your case closer to resolution.
You can find local attorneys using the State and local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
Our forum is a "general legal information" forum - where we can answer specific questions, so if you have a direct question about procedure (such as how to file a particular motion, what do you need to do to oppose a motion, for example), or substantive law (such as what is the statute of limitations for fraud), or similar questions, we can answer those questions for you.
We can also try to direct you to local resources to assist you (such as the local law library) when our information is not sufficient (such as doing detailed legal research in support of a motion).
