01 / Witnesses / Scope & preparation
Match each witness to a fact—not to your side.
Maine Rule of Evidence 602 concerns personal knowledge; expert testimony and lay opinions have separate rules. [1] Our preparation method is to list what each person directly saw, heard or did, when it occurred, and the disputed issue it helps explain.
A person who observed an exchange is different from a friend who heard about it later. An attendance custodian is different from a clinician asked for a professional opinion. Identify those differences before deciding whom to call.
Ask about availability and access needs early. Do not promise a witness that their statement will guarantee an outcome. Do not tell them to omit uncertainty or inconvenient observations. The useful witness is the one who can give an accurate account, not the one most willing to agree.
02 / Witnesses / Scope & preparation
Know what the subpoena commands.
Rule 45 distinguishes testimony, production of records and inspection. A document-production command does not necessarily require personal attendance. The Judicial Branch directs self-represented parties to obtain subpoenas from a clerk’s office; do not improvise an official subpoena from this website. [2] [3]
Before obtaining the form, our suggested preparation note identifies the person or custodian, the specific information needed, the proceeding, the requested date and the lawful method of service. A request for “every record about this family” is not the same as a focused request addressing a disputed issue.
The rule protects people from undue burden and allows objections and protective relief. Treat a subpoena as a regulated court process, not a threat to force agreement. Seek advice before demanding clinical records, privileged communications or material held outside Maine. [2]
03 / Witnesses / Scope & preparation
Delivery and notice are part of the task.
Rule 45(b) sets out service by a nonparty adult and attendance-fee/mileage requirements when attendance is commanded. It also distinguishes notice for discovery/pretrial subpoenas from service of trial/hearing subpoenas. Review the applicable provisions rather than applying one deadline to every request. [2]
Our suggested tracking fields are: form issued; completed scope checked; service arranged; required fees addressed; notice to other parties completed; proof retained; objection received; court action needed. Do not count an unanswered informal email as confirmed attendance.
If a witness cannot attend, address the issue through the permitted procedure. Do not assume a letter is a substitute for testimony or a video connection is authorized. Remote participation requests follow the court’s process. [4]
04 / Witnesses / Scope & preparation
Prepare questions, not answers for the witness.
Write short factual prompts: “Where were you?” “What happened next?” “How do you recognize this document?” “Which part did you personally observe?” Avoid putting several disputed propositions into one question.
Keep a separate note of what you do not know. A witness may not remember a time or may disagree with your interpretation. Practice locating the relevant document, not manufacturing a polished memory. Distinguish a document used to identify an event from an assumption about what the person must say.
Do not recruit a child into adult litigation as a shortcut. Obtain advice about the proper procedure for any proposed child participation, protect the child from coaching, and follow the court’s directions. This guide does not recommend interviewing a child to build allegations against the other parent.
05 / Witnesses / Scope & preparation
A title does not answer a foundation or scope question.
For a professional witness, our suggested preparation questions are: What role did you perform? What material did you review? Which conclusions depend on what another person reported? What are the limits of your opinion? What alternative explanation did you consider?
Do not assume a clinician’s letter, a GAL report and expert testimony have identical rules. Read the appointment order and applicable evidentiary requirements. The companion GAL guide addresses that distinct role.
JTforME editorial standard: Expertise should make reasoning more inspectable, not less. A process that demands deference but resists questions about method has confused professional standing with proof.
