Can Text Messages and Social Media Posts Be Used in a California Custody Case?

By H. William Edgar | Edgar & Dow

A screenshot can be useful evidence if it answers a question the judge has to decide. I want to know who sent it, what came before and after it, and why it matters to the requested order. Evidence Code §§ 1400–1401 address authentication. Hearsay and context are separate questions.

Identify what the exhibit is supposed to prove

If a text confirms a 6 p.m. pickup, use it to show notice or the arrangement. If a social post appears to place someone out of town, establish who posted it, when, and what it actually shows. A repost, scheduled post, or old photograph can mislead when separated from context. Preserve the original thread or export and save dates and account details.

Authentication, hearsay, and completeness

Evidence Code sections 1400 and following address authentication. Evidence Code section 1200 governs hearsay. Whether a message is offered for its truth, for notice, or for another purpose can change the analysis. Section 356 can permit relevant context to make a selected excerpt intelligible. Counsel should assess admissibility and whether a witness or other foundation is needed.

Present a short, usable set of exhibits

Choose communications tied to the order and requested relief. Use a clean copy and keep the original. Redact or protect information as required and check the rules before filing confidential records. In a declaration, explain how you recognize the sender and what happened next. If you need testimony to establish the facts, address witness requirements and scheduling early.

What makes a text message attributable to a sender?

Evidence Code §§ 1400–1401 require authentication. Under People v. Goldsmith (2014) 59 Cal.4th 258, authenticity can be shown by direct or circumstantial evidence. A recipient’s testimony, the surrounding exchange, and distinctive details can help establish who sent a message. Address separately whether the statement is offered for its truth and whether a hearsay exception applies.

How this can play out

A parent offers a screenshot that reads “I cannot make it at five.” The message immediately before it may show that the parents had already agreed to six. The whole exchange can explain what the statement means. Save the original thread, provide the complete sequence to counsel, and identify which part establishes the timing or notice at issue.

Choosing evidence that can withstand a challenge

A parent wants to use screenshots from a social account to establish that an exchange was missed. The account name is recognizable, but some of the posts may show old photographs.

Preserve the complete post, the date it was viewed, identifying details, and other material showing when the event occurred. Identify a witness who can recognize the account or independently establish what happened. Discuss whether the exhibit is offered to show notice, a statement, or the truth of a factual assertion.

Check the exchange records for independent support and do not omit context that alters the meaning. Ask counsel about authenticity, hearsay, and necessary redactions. If the exhibit addresses just one event, limit the presentation to what helps prove it instead of filing unrelated private communications.

Preserve the record before editing it

Save the full thread, dates, and sender details. Keep an original and work from a copy when highlighting, converting, or redacting. If you need to preserve a changing page, document when and how you captured it and provide counsel with information about the account.

How to present posts that refer to other people

Identify who made each statement and what firsthand knowledge the witness has. Separate a statement used to prove notice from one offered to prove that an event occurred. Preserve context and ask counsel what foundation or exception may be needed before offering it.
