How to prepare for custody mediation: what to bring, what to leave out, and what the mediator can and cannot do
Fact-checked · Checked against 5 sources · See the sources
- Custody mediation is a negotiation, not a hearing. The mediator cannot rule against you: the two of you write the parenting plan, and the court reviews it before entering it as an order.
- Bring a written proposed schedule, the current court order, and a short factual record of parenting time. Bring the paper, not the grievance.
- Leave out character claims, ultimatums, money, and anything your child said.
- Mediation communications are generally confidential in some states, Arizona among them, and Federal Rule of Evidence 408 bars settlement talk from being used to prove or disprove the disputed claim. Protected is not the same as private.

What is child custody mediation, and what can the mediator actually decide?
Custody mediation is a structured conversation between two parents, led by a neutral third person, aimed at producing a parenting plan both can sign. The mediator is not a judge, cannot rule against you, and is not allowed to give either of you legal advice. What the mediator does is work trades between you until there is a plan you can both sign.
That single fact should shape everything you bring. You are not there to prove a case. You are there to make a proposal the other parent can live with and a judge will sign.
Ask the court’s family services office before your session whether anything said in mediation is reported to the judge where you live, because it changes what candour costs. Our guide to preparing for a custody evaluation covers the role that does report to the court.
A confidential, guided negotiation in which two parents try to write their own parenting plan, rather than have a judge write it for them.
Is custody mediation court-ordered in family court, or can you choose it?
Both happen. Some states require mediation in a contested custody matter, and Colorado courts can order it. California is the clearest example: Family Code § 3170(a) provides that if a pleading shows custody, visitation, or both are contested, “the court shall set the contested issues for mediation.”
Private mediation is the other route: parents choose it and hire a mediator themselves. Court-ordered mediation might be free. If you asked for it, you pay, and one Colorado firm puts most mediators at $200 to $350 an hour.
Either way the preparation is the same, and it is worth more than the session length suggests.
What should you bring to custody mediation? The child custody mediation checklist
Bring documents that answer a question the mediator will actually ask. Leave the rest at home.
- The current court order or parenting plan, if one exists, plus any pending filings.
- A written proposed schedule, week by week, including holidays, school breaks and summer.
- A calendar: the school calendar, your child’s activity schedule, and your own work pattern.
- A short factual record of parenting time: dates, times, who had the child, what was arranged, what happened. Dated entries, not narrative.
- Practical information the plan will need: addresses, school and childcare details, medical providers, transport arrangements.
- One page listing your priorities and what you can trade. This is the page you will look at most.
“Your mediator may provide you with a list of items or documents to bring to the mediation session(s). Most of it will be child-related documentation. Even if you’ve already provided it in advance, bring copies of the same documents just in case.”
The organising principle is the copy. A folder you can open to the right page in five seconds is worth more than three times the paper you cannot find, even when the mediator already has a set.
How do you prepare for mediation with a written parenting plan?
Write your proposal before you walk in. A parent with a written plan is negotiating from a draft. A parent without one is negotiating from a feeling.
Legal custody and physical custody
Legal custody is decision-making: school, medical care, religion. Physical custody is where the child lives and when. Decide what you want on each, separately, and know which of the two matters more to you.
The schedule, holidays and transport
Write the regular week first, then holidays, then summer, then the boring parts: who drives, where exchanges happen, how a swap gets requested, how much notice a schedule change needs. The boring parts are where next year’s disputes live, so they earn their space now. Our guide to joint custody and visitation schedule examples covers common weekly patterns.
“Bring a written proposed schedule, know your calendar, and rehearse with your lawyer what your priorities and trade-aways are.”
Rehearsing the trade-aways is the part that feels strange and pays best. If you have decided in advance what you can give, you will not give it away in the moment by accident, and you will not refuse it out of reflex.
What should you leave out when you go to mediation?
Leave out the case you would make if this were a trial. Specifically:
- Character claims. Diagnoses, labels and verdicts about the other parent mark you as the parent who cannot co-parent.
- Ultimatums. They end the negotiation, and they get quoted back to you later.
- Your child’s words. Presenting the child as your witness raises a question about why the child was asked.
- Money. Arizona, for one, treats support and parenting time as fully independent, and linking them signals that you see time as leverage.
- History that does not change the plan. If a fact from three years ago would not alter a single line of the schedule, it is not doing any work.
None of that means pretending. It means bringing the specific dated fact instead of the conclusion drawn from it: “the children were returned two hours late on 3 and 17 March” instead of “he is never on time”. Our guide to writing replies for the record covers the same habit in written messages.
What should you not say in child custody mediation, and what can you say instead?
| Instead of | Say |
|---|---|
| “She is completely unstable.” | “On these three dates, the pickup did not happen as arranged.” |
| “It is fifty-fifty or we go to trial.” | “Equal time matters most to me. I have room to move on holidays.” |
| “He is behind on support, so he should not get weekends.” | “I would like to talk about the schedule first, separately from support.” |
| “Our daughter told me she does not want to go.” | “She has seemed anxious around exchanges. I would support a therapist’s input.” |
| “I am the one who does everything.” | “Here is what a typical week looks like, from my calendar.” |
The pattern is the same each time: replace the conclusion with the observation it came from, and let the mediator draw the inference.
What questions does a child custody mediator ask?
Have an answer ready for questions like these:
- What does a typical week look like now?
- What is working in the current arrangement, and what is not?
- What are you proposing, and why is it better for the child?
- Where can you be flexible?
- How will the two of you handle a change of plan, an illness, or a late exchange?
The last one is where a record helps most. A parent who can say how often plans changed last term, and how it was handled, is answering with facts rather than with impressions.
How do you keep a record ready to discuss without reading from it?
There is a difference between having a record and performing one. Reading a log aloud in a mediation session slows the room, and it can signal that you came to prosecute.
What works is having the record close enough to check. If the other parent says exchanges have been fine since June and you know that four were missed, you can say so calmly, with dates, and move on. That is the whole use of it in this setting. The mediator does not need your record. You need your own accuracy.
This is also why a contemporaneous record beats a reconstruction. Entries written at the time carry detail that memory drops, and under the Federal Rules of Evidence they sit closer to the exceptions that matter later: Rule 803(1) covers a statement made while or immediately after the event, and Rule 803(6) covers a record made at or near the time and kept as a regular practice of a business or organization. Neither rule is why you keep it. Both look for a record made close to the event, not the night before. Our guide to keeping a contemporaneous record of parenting time covers how to build one.
Documented keeps a dated, sealed record of parenting time as it happens, so the week before a mediation is spent choosing what to bring rather than reconstructing what happened. See how it works.
What do the best interests of the child mean in mediation, and how do you speak to them?
Custody is decided on the best interests of the child. Colorado and Arizona both write that standard into statute, and the factors differ from state to state. In a mediation you are not arguing the standard, you are speaking it: framing each proposal around the child’s schedule, school, sleep and stability rather than around what is fair between the two of you. Our guide to the best interest of the child checklist covers the factors that recur in most states.
The practical test is simple. Say your proposal out loud and see whether the sentence ends with the child or with you. “He should be with me on Thursdays because I am owed the time” fails it. “Thursdays work better for him because swimming is at six and it is four minutes from my place” passes it.
What happens in custody cases if you do not reach an agreement?
The court decides. What happens next:
- An evaluation, sometimes. A judge can order an investigator or evaluator to interview the parents and children and write a report. In Colorado that is a Child Family Investigator or a Parental Responsibility Evaluator, and it can be expensive.
- A hearing, where each side presents evidence and witnesses and a judge decides the contested issues. Our guide to preparing for a custody hearing covers what comes next.
Anything you have signed can become part of a court order. In Arizona, for example, mediation communications are generally confidential and inadmissible in court. Federal Rule of Evidence 408 bars conduct and statements made during compromise negotiations from being used to prove or disprove the disputed claim, though a court may admit them for another purpose. The protection is real, and it is not the same as privacy. Speak as though the substance may be heard later, because the other side can develop independently anything you reveal.
Do you need a family law attorney for custody mediation?
Rules vary. Arizona allows it either way, and one Colorado firm describes each parent’s attorney attending alongside the mediator. Even where you attend alone, review your proposal, your concessions list, and the parts of the current order you have to work within with a family law attorney first. The mediator cannot give you legal advice. Our guide to questions to ask a custody lawyer covers what to cover in that hour.
This page is general information. It is not legal advice, and it cannot tell you what your state requires.
Custody mediation tips: one short checklist, in order
- Find out which model your court uses, and whether the mediator reports to the judge.
- Write the proposed schedule before you write anything else.
- Assemble the binder: order, filings, calendars, record, practical details.
- Write one page: priorities, and what you can trade.
- Read your proposals aloud and check that each sentence ends with the child.
- Decide in advance what you will not say.
- Bring the record. Do not read from it.
- Sleep, eat, and arrive early. Negotiations reward the rested.
What this guide does not cover
- Your state’s mediation rules. Whether mediation is required, whether the mediator reports to the judge, and how confidential the session is are all state law. This guide gives examples from California, Colorado and Arizona and does not settle the rules where you live.
- Domestic violence and safety. If there is abuse or a risk to you or your child, speak to an attorney before any session. California, for one, handles these cases under a separate protocol, and this guide does not cover it.
- Support and property. This guide is about the parenting plan. Child support, the divorce itself and dividing property are left out.
- Turning the agreement into an order. How a signed plan is filed and approved differs by court. Ask an attorney or your court before you sign.
Frequently asked questions
How long does custody mediation take?
It varies by court and mediator, and a session can take hours. In Colorado, one firm notes, the date is typically set a few weeks or more than a month ahead, which gives everyone time to prepare.
Is custody mediation confidential?
Often, but the rules are state law. In Arizona, mediation communications are generally confidential and inadmissible in court, and Federal Rule of Evidence 408 bars settlement talk from being used to prove or disprove the disputed claim. Ask your court whether anything said in mediation is reported to the judge, and speak as though the substance may be heard later.
What are the most common mistakes in custody mediation?
Arriving without a written proposal, arguing the past instead of the plan, making an ultimatum, and bringing the child’s words into the room. Three of the four are avoidable at the kitchen table the night before.
Can you bring your own notes into a mediation session?
Yes. Your own record of parenting time is yours, and having it to hand is normal and useful. Bring it to check yourself, not to read out.
What is the difference between mediation and a custody evaluation?
A mediator helps the two of you reach your own agreement and cannot rule against you. An evaluator, such as a Child Family Investigator in Colorado, can be ordered by the judge to interview the parents and children and compile a report for the court. They are different roles with different rules.
