I'm not sure what you are asking, but here goes.
Discovery and motions are procedures your attorney uses in your case.
Discovery refers to finding out facts needed in the case such as pay stubs, or phone records.
Motions are filed by your attorney to the court for a multitude of things. Examples would be, a request for a deposition, request for child support, or to stop harassment.
Does this help?
I'll tell you this, be very clear with your attorney what it is that you expect out of him/ her. My attorney tried coasting into mediation and didn't prepare worth a darn until I stayed on her. Both attorneys would rather settle out of court. Settling can be a great thing, but make sure it is something that you feel is best and not something you are forced into.
My sister just graduated from SMU Law School in Dallas, TX.
The top 5 reasons she gave me for wanting to practice law were
1. To defend the rights of people
2. Preparation to be a Politician (apparently it looks good on a political resume to have a JPG)
