A mailed letter does two jobs at once here — it delivers the information, and it documents that you tried to. ## How it works 1. **Start from the template** - Fill in the child-focused facts; keep it to one page. 2. **Export to PDF and upload** - Or write it in the letter flow directly. 3. **Confirm addresses** - USPS address checks catch errors before printing. 4. **Choose First Class or Certified Mail** - Certified adds tracking and an Electronic Return Receipt signature record; the tracking number is issued right after checkout for typical letters. 5. **We print and mail it** - Keep the PDF and the tracking record with your parenting documentation. ## Key takeaways - **Check your custody order first** - Many orders name a required communication channel (email or a co-parenting app). If yours does, use that channel; a letter then documents attempts, it does not replace the required channel. - **Write for the judge who might read it** - Every line child-focused, factual, and calm. No relationship content at all. - **Brief, informative, friendly, firm** - State the information, make one clear request, give a reasonable respond-by date, skip everything else. - **Use Certified Mail when it functions as notice** - Schedule changes, relocation, medical decisions, or anything your order requires you to communicate: send it with proof. Routine updates can go First Class. - **This page is general information, not legal advice** - Custody situations vary by state and by order; when in doubt, ask your attorney before sending anything. [Mail this letter](cta) ## First: what does your order say? Before writing, reread your custody or parenting-plan order for a communication clause. Three common situations: - **The order names a channel** (email, OurFamilyWizard, TalkingParents, etc.) - Use that channel for the actual communication. A letter is still useful to propose restoring it or to document that the named channel is being ignored — but it supplements the order, never sidesteps it. - **The order is silent on communication** - A letter is a legitimate, documentable channel. This template is built for that case. - **There is a protective order or no-contact provision involving you** - Do not send anything. Child-related communication in those situations runs through the mechanism the court set up (often counsel or a designated third party). A letter can be a violation. ## Copy/paste template (child-focused communication letter) ``` [Your Name] [Your Address] [City, State ZIP] [Date] [Co-Parent's Name] [Their Address] [City, State ZIP] [Co-Parent's First Name], I'm writing by mail because my calls and texts aren't going through, and [Child's Name]'s schedule still needs coordinating. I'll keep this brief and factual. [The information, in numbered points. Examples:] 1. Pickup this Friday [Date]: I plan to pick [Child] up from school at [Time] per the current schedule. Please let me know by [Date] if anything has changed. 2. [Child]'s dentist appointment is [Date, Time] at [Location]. [I will take them / Please confirm who is taking them.] 3. School's [event] is [Date]. I plan to attend. Going forward, I'd like to agree on one reliable channel for [Child]-related communication so neither of us misses anything. I suggest [email address / a co-parenting app]. If you prefer a different option, I'm open to it — please reply by [Date, about 7-10 days out] at [your email] or by mail. I'll keep everything through that channel about [Child] only. [Your Name] ``` ## Rules that keep the letter court-safe - **Child's needs only** - No history, no grievances, no commentary on the block itself beyond the one neutral factual line ("my calls and texts aren't going through"). - **Facts and dates, not characterizations** - "Pickup is at 3:15 on Friday" survives a courtroom reading. "You always make this difficult" becomes an exhibit against you. - **One clear, answerable request** - Confirm a time, choose a channel, acknowledge an appointment. Vague letters get vague silence. - **Reasonable deadlines, softly stated** - "Please reply by [date]" is documentation-friendly; "you have 48 hours" is escalation. - **Keep your copy** - Save the PDF you mailed and any tracking or delivery record with your parenting records, organized by date. ## When to use Certified Mail (and when not to) - **Use Certified Mail with Electronic Return Receipt** when the letter is *notice*: proposed schedule changes, travel or relocation notices, medical or school decisions your order requires you to communicate, or a formal proposal to establish a communication channel after being blocked. You get a USPS tracking number — issued right after checkout for typical letters — and a signature record on delivery that you can keep with your records. See [Certified Mail online](/certified-mail-online). - **Use regular First Class** for routine, low-stakes updates where a certified envelope would raise the temperature without adding anything. A pattern of certified-mailing every minor update can itself look aggressive; match the instrument to the stakes. ## Before you send (checklist) - Reread the custody order's communication and notice provisions. - Delete any sentence that is about the two of you rather than the child. - Confirm every date, time, and address you state is accurate — errors in a documented letter cut against you later. - Decide First Class vs Certified based on whether this letter functions as notice. - If a hearing, motion, or attorney is already in play, run the letter past your attorney first. ## FAQs - **Can my co-parent legally block my number?** Blocking a phone number is not itself illegal, but courts generally expect parents to maintain reasonable child-related communication, and many orders require it. The productive response is not arguing about the block — it is documenting that you communicated the necessary information anyway and proposing a workable channel. Whether the blocking violates *your* order is a question for your attorney. - **Does a mailed letter count as documentation?** A dated letter plus your saved PDF copy shows what you sent and when; Certified Mail adds USPS acceptance, tracking events, and — with Electronic Return Receipt — a delivery signature record. Courts weigh all of this case-by-case, which is exactly why the letter itself must be calm and factual. - **Should every letter be certified?** No. Certified for notices and decisions; First Class for routine logistics. Escalate the proof level with the stakes, not with your frustration. - **What if they don't respond at all?** Keep records of each necessary communication, keep each one child-focused, and raise the pattern with your attorney or at your next hearing rather than by sending angrier letters. Two or three unanswered, well-documented letters about real logistics say more in court than anything you could add in tone. - **Can I use this to talk about our relationship?** No. One channel, one subject: the child. Anything else undermines both the letter and you. ## Resources - [Certified Mail online (tracking + Electronic Return Receipt)](/certified-mail-online) - [How to contact someone who blocked you (full guide)](/relationship-letters/contact-someone-who-blocked-you) - [Mail court documents online](/court/mail-court-documents-online) - [Delivery times](/delivery-times) ## Related - [Get your belongings back: letter template](/relationship-letters/get-belongings-back-letter-template) - [Boundary-setting letter template for a family member](/relationship-letters/boundary-setting-letter-template-for-family-member) - [Mail a letter online](/send-letter-online) ## Ready to send it?
