No. It can be just mailed to him/her. That's all.
A summons.
Subpoena.
You will be served with a court order if there is a judgment against you. But long before that you would have been notified of the court proceeding.
Body Attachment is a court order to arrest a person who has failed to appear at court in response to a witness subpoena.
By issuing a subpoena and confirming that the subpoena has been served on the wittness. If the person doesn't respond to the subpoena in some cases the DA can then ask for a Bench Warrant to issue. The wittness could then be arrested and asked questions while in custody. The potential witness is served a subpoena and is legally obligated to appear at the time stated or be charged with contempt of court. In which case a warrant will be issued for the person's arrest and after the person is taken into custody he or she will still be brought into court to testify. The prosecutor can request the court to deem the person a hostile witness and the judge can order the individual to answer questions put to them or face further contempt and obstruction charges.
If the court determines that you were served, it will likely enter a default order - you will not like the terms of that order.
Criminal attachment charge is a court order to arrest an individual who failed to appear in court in response to the witness subpoena.
A court order should be served on the issuing authority.
A subpoena, which comes from the Latin for "under penalty". Subpoenas may be issued to compel a witness to appear in court and testify, or to compel the production of evidence. In either case the person served with the subpoena must either do the thing named in the document, or face punishment.
Witnesses are brought to trial in two main ways: 1. They are asked, and voluntarily appear. This is risky, as they may not, in fact, appear. Without them, the party who needs them may be unable to prove their claim or defense. 2. By serving them with a subpoena. A subpoena is essentially a court order commanding the witness to appear at a specified time and place to offer testimony. If it is necessary for the witness to bring documents or other material, a "subpoena duces tecum" is served. This is essentially the same as a plain subpoena, but is titled differently and specifies the material that is to be brought at the time of testimony. If the witness does not appear despite being served with a subpoena, he/she may be held in contempt (for disobeying a court order). It generally also lays a better predicate for getting the hearing or trial continued (delayed), because the court will see that the party did all that he/she could do get the witness to the hearing/trial. The subpoena must be accompanied by a statutory mileage fee, the amount of which can usually be determined from the Clerk of the Court. If the witness is an "expert witness", (for example, a physician or someone else with technical, specialized knowledge that is necessary for the required proof), he/she may request a reasonable expert witness fee to attend. If not paid, he/she may have a basis for not complying with the subpoena. If the party subpoenaing such party feels that the fee requested is out of line, a hearing may be set with the court to determine reasonableness.
It is not up to the person who takes out the order to serve it. That is done by a court server. If the person being served can not be found, the order can not be served.
By subpoena, or summons, or if the person is actually in court, the judge can order it personally.
