Legal Question in Personal Injury in Maryland

If you are involved in active litigation, your current lawyer would be the ideal source to answer these questions since s/he would know exactly what stage your particular case may be in.

That being said, generally speaking one can "add" to a complaint only by amending the pleading. In other words, one must file a new amended complaint. Depending on the stage of things, you may or may not need to get court permission to amend. Sometimes a minor amendment can be made at trial but I presume your amendment will be in writing. In any case, there is no new filing fee for amending a complaint, although the other side has the absolute right to get a copy and have time to answer. One cannot "add" to summons since these are issued by the Court and attached to whatever pleading is being served. If you need to "reissue" summons then there may be an additional court fee for that.
