What counts as evidence in a child custody case?

Start with the issue, not the file type

A message, photograph or receipt is only a source. Its value depends on the question it helps a reviewer answer. Before collecting more material, write the issue in one neutral sentence. Ask, for example: Which handovers happened later than the agreed time between March and May? That is more workable than asking how to prove the other parent is unreliable.

Then identify the baseline. That may be a current order, parenting plan, written agreement, school timetable or established routine. The baseline explains what was expected. Your event record explains what happened. An attached source supports one or more details. Keeping those three layers separate prevents a screenshot from carrying more meaning than it can support.

This is also why “evidence” and “records” are not interchangeable. Records is the wider private record you keep. Evidence is material an expert or court may decide is relevant to a particular question. Casewell helps organise the first. It cannot decide the second.

The four tests for a useful custody record

Use four tests before adding a source to your working collection.

1. Relevance: Which child-related issue or event does this source explain?
2. Source: Who created it, where did it come from and is the original available?
3. Context: What came before and after it, and what limitation should a reviewer know?
4. Connection: Which dated timeline entry or question does it belong to?

Records can pass some tests and fail others. A cropped message may be relevant but lack context. Complete school attendance data may be reliable as a school record but irrelevant to the issue being reviewed. Notes made months later may still help explain your memory when the delayed recording date is stated openly.

Do not improve a weak source by writing a stronger description. Label the limitation instead. Screenshot supplied by Parent A. Original thread not available is more honest and useful than presenting the screenshot as a complete conversation.

Twelve common record types and what each may show

Use the table as a routing tool, not a promise about admissibility. The next sections explain how each type fits into a defensible working record.

Orders, parenting plans and calendars establish the baseline

Start a record set with the document that governed the arrangement on the relevant date. Keep the whole order, plan or agreement rather than only the paragraph that appears helpful. Record its issue or signature date, when it took effect and whether a later version replaced it. If the wording is unclear, copy it accurately and save the interpretation question for a lawyer or solicitor.

A calendar then shows planned events. A parenting-time log shows actual events. Keep those concepts separate. For each exchange, note the scheduled start and end, actual time, location, agreed change, cancellation and make-up time. Everyday events belong in the log alongside disputed ones. Recording only negative outcomes can hide the denominator and make a pattern difficult to assess.

A calendar entry created after the event is not the same as a calendar invitation sent beforehand. Keep both creation timing and event timing where that distinction matters. If you need a repeatable structure, the parenting-time log template keeps planned and actual time on the same row.

Messages and emails need the surrounding conversation

Messages can document requests, responses, changes, acknowledgements and exact wording. They can also mislead when a single line is separated from the conversation around it. Capture enough of the thread to show participants, date, time, channel and the messages right away before and after the relevant passage. Keep your own messages too.

Where possible, keep an export or original device copy as well as screenshots. Name the platform and note any missing segment. Do not crop away a sender, date or reply that changes the meaning. A delivery indicator may show that a platform marked a message as delivered. It does not always prove that a person read or understood it.

Summarise one child-related issue as one messages event rather than creating a timeline entry for every message. The complete thread remains the source behind that summary. See the detailed guide to keeping text messages with context and the messages-log template.

Journal entries and incident records should label the source of each fact

A contemporaneous note—one made at or near the time—can keep details that would otherwise be forgotten. Include the event date and time, the date and time you wrote the note, location, people present, direct observations, action taken and supporting source references. If the date is approximate, say so.

Separate direct knowledge from reported information. I arrived at 17:55 and left at 18:25 is a direct observation. The school office told me at 09:10 that no collection authorisation had been received identifies a third-party source. My child said… needs particular care. Record spontaneous words and context without questioning the child for evidence or adding an adult conclusion.

Do not silently rewrite an earlier entry when new information arrives. Add a dated correction or follow-up and link it to the original. The factual incident-report guide shows how to keep observation, interpretation and evidence distinct.

School, medical and childcare records add independent context

Third-party records can give dates and observations created for everyday expert purposes. School material may include attendance, lateness, collection records, teacher correspondence, support plans and activity information. Medical material may include appointments, treatment instructions, prescriptions and clinician notes. Childcare records may show booking, attendance and authorised collection.

Keep the complete document and the covering message or portal context where available. Record when you received it separately from the event date. Do not alter the original to highlight a passage. Make a working copy for annotations. A school record can show what the school recorded. But it does not automatically explain the cause. A clinician's note may report what a parent said without on its own verifying it.

These records contain sensitive information. Limit copies, use a secure transfer method and ask before sharing records about a child or third party. The dedicated school-record guide and medical-record guide cover their different privacy and context requirements.

Receipts and payment records need the agreement beside the amount

A receipt can show that a purchase occurred, when it occurred and what it cost. A bank record can show a payment path. Neither document alone decides whether the expense was needed, agreed, shared or reimbursable.

For each item, record the child-related purpose, date, amount, currency, payer, agreement or order wording, repayment request, response and balance. Attach the receipt and relevant message. Keep disputed items in the same ledger as agreed items and mark their status. Removing them creates an incomplete account.

Separate ongoing support from itemised child expenses unless the applicable document treats them together. Labels vary by legal area and by order. The child-expense tracker gives a copyable row, while Casewell's expense-tracking workflow keeps the receipt and repayment status attached to the dated record.

Photos, videos, calls and recordings require extra preservation care

Keep an original photo or video file before editing, resizing, annotating or sending it through another app. Record who made it, when and where, what device or account supplied it and which event it supports. Metadata can help with provenance, but metadata can be missing or changed and should not be described as conclusive.

For calls, keep the device call log and original voicemail if available. A factual note can record the participants, approximate duration, subject, action agreed and words you remember accurately. It should not be presented as a transcript. Laws on recording conversations differ substantially, including between US states. So get local advice before making, sharing or relying on an audio recording.

A photograph shows what appears inside its frame. A call log shows that the device recorded a call. Neither explains motive or a wider history without other records. Read the fuller guides to photo and video preservation and call logs and voicemail.

Preserve originals and make separate working copies

An original is the closest available version of the source as created or received. Keep it before adding arrows, highlights, redactions or notes. Use a separate working copy for review. Keep a simple preservation note: source, date received, original location, file name, working-copy name and any known change made during export.

Use stable file names that sort consistently, for example 2026-03-11_MSG_school-pickup_thread.pdf. Avoid renaming an original repeatedly. If a platform offers an export, keep the export instructions or format information. Back up important originals in a secure location consistent with expert advice and your privacy obligations.

Do not claim a forensic chain of custody merely because you used careful folders. A personal preservation log is still valuable. But formal authentication and disclosure rules are local. If you want one private place to connect a source to the event it explains, start a dated Casewell record and keep the untouched original alongside the working reference.

Build an evidence index before building a narrative

A master index is a map of the sources you hold. Give each item a stable ID, short neutral description, source date, date received, original location, linked issue, linked event and privacy status. The index should help another person find the original without reading a long account first.

Next create a selective timeline. Each line should contain the event date, neutral event summary, outcome and source IDs. The timeline is not the evidence itself. It points to the fuller entry and source. Include important normal outcomes, corrections, notes and resolved matters so that the timeline does not imply a pattern by omission.

Review by issue as well as by date. An expert may need to see all medical-information exchanges together, while still being able to place each exchange in time. Casewell can keep dated entries and files connected. Also, the free custody timeline builder can help test the structure before you prepare a report.

Select records for a question, not for maximum volume

A private archive can be comprehensive. A review pack should be selective. Begin with the question or decision for which advice is needed, then include the current baseline, short issue summary, focused timeline, source index and key originals. Keep background material available but separate.

Flag gaps and contrary facts. State when a source is incomplete, an event date is approximate, a later note was received or an issue was resolved. An expert can assess a visible limitation more efficiently than discover one after relying on a polished summary.

Do not send a large unencrypted file or unrestricted folder of child records without asking how the recipient wants to receive it. The lawyer and solicitor planning guide explains a focused review pack. When you are ready to share a selected timeline, Casewell's PDF report workflow lets you choose the relevant dated records rather than exporting the entire private archive.

Jurisdiction changes terminology, procedure and admissibility

There is no universal list of custody evidence that every court must accept. Court process, privacy, disclosure, authentication and recording rules differ. The main parenting terms vary too. England and Wales generally use child arrangements. Australian federal family law uses parenting arrangements. Canadian federal law uses terms such as parenting time and decision-making responsibility, while US terms changes by state.

Official guidance also shows why local court process matters. California Courts explains that documents or witness statements generally need to be filed and served for a family-law hearing. New York describes testimony, reports and a best-interests hearing. The Federal Circuit and Family Court of Australia explains that affidavits set out facts rather than opinion and that referenced documents need the correct annexure process. England and Wales has its own forms, witness-statement and permission rules.

Treat examples on this page as record-keeping guidance, not filing instructions. Check the current order and local court directions, and ask a qualified local expert what should be kept, disclosed, filed, served, redacted or left out.

Privacy, safety and children come before documentation

Collect only material with a legitimate child-related purpose. Avoid monitoring accounts or devices you are not authorised to access, recording where local law prohibits it, or gathering unrelated information about the other household. Protect addresses, account numbers, health information and third-party details.

Do not ask a child to investigate, choose sides, repeat an account or produce evidence. If a child says something spontaneously, record the exact words, setting and your response without repeated questioning. Safeguarding concerns need an appropriate expert or emergency response. A private record is not a safety intervention.

If disclosure of a record could expose a safe address, refuge location, medical information or another protected detail, get advice before sharing it. Casewell is designed for private organisation. But the user still controls what is imported and exported. Review every selected file before producing a report.

Turn scattered sources into a record another person can follow

The useful sequence is straightforward:

1. Define the issue and identify the baseline.
2. Record the dated event and keep the original source.
3. State the source's limitation and add a stable reference.
4. Connect the event to a selective timeline.

That method works whether the source is a message, receipt, school letter or photograph.

You do not need to document every irritation. Keep information that explains a child-related arrangement, decision, expense, event, wellbeing concern or needed follow-up. Record everyday outcomes as well as problems. Revisit the index periodically so resolved matters and later notes remain visible.

If your sources are still spread across your phone, email and paper folders, organise the next relevant event in Casewell. Add the factual entry, attach the source, and let the timeline grow one reviewable record at a time.

Keep the event and its source connected

Casewell lets you create a dated factual entry, attach the source that explains it and later select relevant records for a clear PDF. Your private archive remains broader than any single review pack, while you control what is exported.
