Calling Witnesses in Family Court: Questions Parents Ask

You have a hearing date, and you're writing names down: your sister who saw the pickup that went wrong, your child's teacher, the neighbor who hears everything. Who can actually help? The witnesses who matter are people who saw or heard things themselves, plus any qualified professionals you can bring in. Getting them to court usually means a subpoena that someone other than you must serve. The judge controls how many testify and for how long, so a few strong witnesses beat a crowd. Below, we cover each of those points in turn.

Who belongs on your list

Start with one question for every name: what did this person see or hear for themselves? Evidence law is built around firsthand knowledge. The Federal Rules of Evidence govern federal courts, not state family courts, but they show the principles most courts work from. Your own state's rules decide the details. Under Federal Rule of Evidence 602, an ordinary witness may testify about something only if there is evidence they have personal knowledge of it, and their own testimony can supply that evidence. Rule 601 says that, in general, every person is competent to testify. When state law supplies the rule of decision, though, state law decides who is competent.

That firsthand requirement removes a lot of names. A friend who only knows what you told her can't add much. The hearsay rule (Federal Rule of Evidence 802) generally bars out-of-court statements offered to prove that what they say is true, unless a rule or exception allows them. "He told me he'd been drinking before the drive" can run into that wall. "I watched him stumble to the car" usually doesn't.

Ordinary witnesses can give some opinions, within limits. Under Rule 701, a lay witness's opinion has to meet three conditions:

• It is rationally based on what the witness perceived.
• It is helpful to the court.
• It does not rest on scientific, technical, or specialized knowledge.

Your child's soccer coach can say your son seemed withdrawn and tearful at practice after weekend exchanges. The coach can't diagnose anxiety. That kind of conclusion belongs to an expert.

Experts and court professionals

A therapist, pediatrician, or psychologist can offer the specialized opinions lay witnesses can't. The federal standard for expert testimony is Rule 702. Under it, the party offering the expert must show the court that it is more likely than not that:

• the expert's knowledge will help the court,
• the testimony rests on sufficient facts or data, and
• reliable methods were reliably applied.

Under Rule 703, an expert may also rely on information that would otherwise be inadmissible, if experts in that field would reasonably rely on it.

One practical problem catches many parents off guard. You often can't simply order an expert to give you an opinion. In New York court proceedings, for example, an expert witness generally can't be compelled to testify by subpoena. A party can, however, hire and pay an expert to appear. Rules differ by state, so treat an expert as someone you arrange in advance, not someone you summon at the last minute.

Court-connected professionals have their own rules. In California, subpoenaing personnel such as a Family Court Services mediator or evaluator requires an advance deposit under Government Code § 68097.2. The statute sets that deposit at $275 for each day of attendance.

Your case may also have a guardian ad litem (GAL), a person the court appoints to look out for the child. Connecticut's guidance describes a GAL as an independent officer who acts as the court's "eyes and ears." The GAL investigates the child's circumstances and recommends what serves the child's best interests. A GAL is not either parent's lawyer. Don't count on the GAL as "your" witness. Their job is to report what they find.

What about your children?

Many parents wonder whether their child should testify. Courts generally try hard to keep children out of the parents' fight. California offers a clear example. Under Family Code § 3042, if a child aged 14 or older wants to address the court about custody or visitation, the court must allow it. The only exception is if the court finds, on the record, that it isn't in the child's best interests. California law and Rule of Court 5.250 also provide other ways to hear from children, such as:

• interviews in the judge's chambers,
• a lawyer appointed for the child, or
• evaluations.

These methods spare the child from being questioned in open court in front of both parents. Ask about these options before you think about putting a child on the stand.

How to get witnesses to court

Once your list is set, the subpoena is the tool that makes appearances official. A subpoena to testify is called a subpoena ad testificandum. A subpoena to produce documents or other evidence is a subpoena duces tecum. In practice, many lawyers subpoena cooperative witnesses too, not just reluctant ones. A subpoena gives a witness something to show an employer and fixes the date. Treat that as a common practice, not a legal requirement.

The subpoena comes from the court handling your case. Under the UCCJEA, a uniform law adopted across U.S. states and territories, there are rules for deciding which state's court has authority over custody. If you and the other parent live in different states, confirm where the case belongs before anything else. In federal civil cases, Federal Rule of Civil Procedure 45 requires subpoenas to issue from the court where the case is pending. The clerk issues a signed but otherwise blank subpoena to a requesting party, or an attorney authorized in that court can issue one. State family courts have their own versions. In New York Family Court, a parent without a lawyer generally needs a "So-Ordered" subpoena signed by the judge, or must follow specific clerk procedures. Lawyers, by contrast, can issue subpoenas themselves.

Next comes service, the step parents most often get wrong. You can't hand the subpoena to the witness yourself. In states such as New York and Minnesota, the papers must be delivered by someone who is not a party to the case and is at least 18 years old.

Budget for witness fees, too. In California civil and family cases, the standard statutory fee is $35 per day of attendance plus 20 cents per mile, both ways. Other states set their own amounts.

A subpoena is a court order, and courts can respond when witnesses ignore one. Penalties vary by jurisdiction. Ask the clerk or a lawyer how your court enforces subpoenas.

How many witnesses should you call?

There's no single number. Judges have strong tools to keep a hearing focused. Under Federal Rule of Evidence 403, a court may exclude relevant evidence when its value is substantially outweighed by undue delay, wasted time, or "needlessly presenting cumulative evidence." Under Rule 611(a), the court controls how witnesses are questioned and in what order. The goals are to get at the truth, avoid wasting time, and protect witnesses from harassment or undue embarrassment. Many family courts also set time limits or pretrial schedules, so check any orders in your case.

Here's the practical lesson, and this part is opinion. Five relatives each saying you're a loving parent may count, in effect, as one witness, and the judge may lose patience before the fifth. One witness for each disputed fact is a better plan. Choose the teacher for school attendance, the neighbor for the incident at the curb, and the counselor for your child's progress. Each one should cover ground the others can't.

How long will witnesses be at court?

No rule sets a length, and estimates are unreliable. Delays, earlier cases, and long cross-examinations can all push a witness's turn later. The safest advice is to have each witness keep the whole day open. Also warn them about one surprising rule. Under Federal Rule of Evidence 615, the court must order non-party witnesses out of the courtroom if either side asks, and it can do so on its own. Those witnesses may also be blocked from learning what was said in their absence. Many state courts follow similar practices. Your witness may spend most of the day in a hallway and testify for a short stretch. Tell them in advance, so the wait doesn't feel like something went wrong.
