The deadline for appealing a Judge's final order to the Law Court is 21 days after the clerk enters the final order on the docket. File any appeal with the District Court clerk. You will probably need a lawyer to help you go forward with an appeal. Although some of the costs can be waived, appeals are expensive.
CAUTION: Generally speaking, the court reviewing an appeal can only overturn "mistakes of law." So, if you think that the Judge has made a legal error, you can appeal that issue. This means that you think the Judge violated an existing law. However, in many cases, you may disagree only with the Judge's "findings of fact." In other words, the Judge based the decisions on someone else's version of the truth, not yours. In that case, the appellate court rarely second-guesses the trial court Judge. It will almost always adopt a trial court's findings of fact (assuming they are based on some real evidence). So this is not a good reason to appeal. We advise talking to a lawyer, if you can, before investing time and money in an appeal.
