Your neighbor now has the right to seek court adjudication of the dispute. The way your neighbor will call your dispute to the court's attention is to write and file a complaint . The complaint is the first document in a legal action. Your neighbor will probably hire a lawyer to draft and file the complaint. In order for any court to decide your case the court must have what is called jurisdiction .
Jurisdiction means the right to decide.
Courts need jurisdiction over the persons and subject matter in the case. Your legislators decide the laws governing subject matter , or which courts are allowed to decide which things. Your neighbor could not, for example, file his case in the United States Supreme Court. The legislatures give the courts jurisdiction on the authority of you and the rest of the electorate. In other words, a judge just can't order any thing that he or she wants.
