is this the right usage ?
- He is required to be present at the court.
- It is required that he be present at the court
- The court requires him to be present at the court
- the court requires that he be present at the court
Yes, that is the correct usage, although the construction with the subjunctive for this particular semantic is very heavy. A more likely construction would be, "His presence at court is required" or "The court has mandated his presence."
(However, you do have the subjunctive construction and the when-to-use basically correct.)
