The Court of Appeals would be the proper venue but the first place you should go is to a local attorney with Appellate experience.
Yes, very technical process though. Lots of deadlines and requirements. Talk to an attorney.
To questioners from West Virginia & New York: Although I am licensed to practice in your state, I practice on a day-to-day basis in Massachusetts. I answer questions in your state in areas of the law in which I practice, and in which I feel comfortable trying to offer you assistance based on my knowledge of specific statutes in your state and/or general principles applicable in all states. It is always best, however, to work with attorneys and court personnel in your own area to deal with specific problems and factual situations.
As a broad answer to your query, yes, an appeal of a final judgment of the Probate and Family Court is filed in the Appeals Court. What you need to understand is that an appeal is very different from a trial court action. The procedures and deadlines are strict. The basis for your case, the written brief, is a significant and specialized writing. Oral argument is nothing like a hearing or trial in the trial court.
Rather than asking where an appeal would be taken you should be asking, does your case warrant appeal? Judges make mistakes, but not all cases that can be appealed should be appealed.
There are deadlines for filing a Notice of Appeal, obtaining transcripts, filing in the Appeals Court, etc. An appellate attorney will be able to provide you with an opinion regarding whether you have a viable case for appeal; whether it is a case that may be appealed directly to the Supreme Judicial Court rather than the Appeals Court.
In short, I believe you really want to discover whether you should be appealing the case. What is your potential for success, what are the potential negative side effects, and is it financially viable given the judgment. To obtain an answer you should be in contact with an appellate attorney. As an appellate attorney I do just what I am suggesting, I assess cases for appeal and represent clients on appeal. Judges make mistakes, but not all cases that can be appealed should be appealed. Discuss your particular situation with an appellate attorney immediately so that you do not miss deadlines!
