Your question does not provide much information so I will just answer that seeking (and receiving) an additional 30 days to respond to discovery is pretty routine in North Carolina. It may be strategic but more likely they waited until the last week or the client had difficulty getting a response together. Don't read too much into it.
The answer depends on whether there is an open matter in Superior Court. If the matter was filed in Court and that action was stayed pending arbitration you would probably need to pay only a motions fee but if there is no open civil matter you need to file a complaint and the filing fee would be for a new matter.
Happy to answer your question but need more information. Assuming the order you want to appeal does not resolve all of the issues in your case, your right to appeal what is called an interlocutory order is very limited. Generally speaking the appeal of such orders must wait until final resolution of the case. However, in this case since it did not resolve everything you can continue discovery.
If the order did resolve all issues (i.e., was a dispositive order) you have thr right to appeal...
There are a variety of reasons to take a deposition and how you take it and how you use or don't use evidence depends on your objective. Are you seeking to learn what the other side knows or commit their testimony to the record? Is the evidence you want to "enter" something that you need explained to you or is there some other purpose for using it before trial. These are critical questions that cannot be answered on AVVO.
The rules of evidence are not critical at the deposition but you...
Under contract law you are entitled to recover what you bargained for at the bargained for price. So the answer is multi-layered. You are entitled to the money that you paid for things he didn't do. You can't recover what you paid someone else to do unless you already paid the original contractor for it or it cost more with the replacement.
To recover if he refuses to pay you back you will need to file a Complaint. This amount is small enough that you could do so in small claims court....
I am sorry for what you have been through and it is likely that you do have a legal case. The standard though is not simply that things went horribly wrong. To have a case you will have to show what you have gone through was caused by the professional negligence of the doctors or hospital staff.
North Carolina law requires a medical opinion that it was negligence. You should definitely consult a lawyer in your area who handles this kind of case. Generally, they will not charge a fee...
You cannot bury a court in paper. If you have a motion to file you can file a proper motion and cite relevant cases but you must have a good faith basis for any filing.
Although courts are more forgiving of pro se parties the rules still apply to you.
Without knowing what kind of case or what you are trying to accomplish I cannot give much guidance but I strongly recommend that you hire qualified counsel before trying to bury the court in paper.
Summary ejectment is an expedited procedure to evict a tenant (usually for non-payment of rent or some improper use of the property). It does not preclude an action for past due rent but is designed to decide relatively quickly the possession issue.
