Indiana is a one-party consent state: if you are a party to a phone call or conversation, you may record it without telling the other person.
A recording you made as a participant is generally usable in an Indiana custody case, subject to the court's discretion on relevance and authenticity. Recording a conversation you are not part of falls outside the participant exception and is a felony.

Short answer: yes, if you are on the call
Indiana is a one-party consent state. If you are a participant in a phone call or conversation, you may record it without telling the other person, and without breaking the law. This matters for a parent trying to keep an honest record of a difficult co-parenting relationship — you do not need your co-parent's permission to press record on your own calls.
The statute and how it is written
Indiana's wiretapping law lives in Title 35, Article 33.5 of the Indiana Code. Ind. Code § 35-33.5-5-5 makes it a crime to knowingly or intentionally intercept a wire, electronic, or oral communication. But the definition of “interception” itself, at Ind. Code § 35-31.5-2-176, only covers acquiring a communication “by a person other than a sender or receiver.” In other words, Indiana does not carve out a separate exception for participants the way some states do — it defines the crime so narrowly that a sender or receiver recording their own call was never inside it to begin with. The practical result is the same as a one-party consent rule: your own presence on the call is what makes recording lawful.
What happens if you get it wrong
The protection only covers calls and conversations you are actually part of. Recording a conversation between two other people — hiding a phone in a room, tapping a line you are not on, or asking a third party to secretly record your co-parent for you — falls outside the statutory definition and is a serious crime. Under Indiana Code, unlawful interception is a Level 5 felony, carrying one to six years in prison and a fine of up to $10,000. A person whose communication was intercepted unlawfully can also pursue a civil claim against you. None of that risk applies to a call you are on — the exposure is specifically for recording other people's conversations without any party's consent.
Using a recording in an Indiana custody case
A recording you made as a participant is generally admissible in an Indiana family law matter, in the sense that the recording law itself does not bar it. Admissibility at the courthouse is still the judge's call: they will look at relevance, whether the file is a complete and unedited original, and whether it is more probative than prejudicial. A short, out-of-context clip rarely helps; a complete, dated, unaltered recording of an exchange about pickup times, missed calls, or a heated argument tends to carry far more weight. Keep the original audio file, note who was on the call and when, and resist the temptation to trim out the parts that make you look less patient — an edited recording can undermine your credibility with the court even if the underlying content was lawfully captured.
A recording is not the whole case
Judges in high-conflict custody matters see a lot of one-sided evidence, and what tends to land badly is a single dramatic clip presented without context. A recording works best as part of a pattern: several calls over weeks or months that show a consistent dynamic — missed exchanges, disparaging comments, or repeated interference with parenting time — rather than one argument taken out of context. If you are building a file for an Indiana custody hearing, treat each recording the way you would treat a single exhibit: dated, complete, and consistent with everything else you are submitting.
The interstate caveat: what if your co-parent lives elsewhere?
Indiana's one-party rule protects a call made from Indiana between people who are all in one-party states. If your co-parent is in an all-party consent state — California, Illinois, Pennsylvania, and several others — the safer, generally accepted practice is to follow the stricter rule for the whole call: announce that you are recording, or otherwise make sure every party knows. Whether a court in either state actually applies its own law or the other state's law to a specific call is a fact-specific legal question, not something a general guide can answer for your case. If your calls regularly cross state lines with your co-parent, confirm the rule with a licensed attorney before you rely on a recording made without an announcement.
How to document it so it holds up
Recording is only one piece of a record that a judge will trust. Preserve the full text thread instead of a cropped screenshot, keep accurate dates and times on everything, and store copies somewhere your co-parent cannot delete or edit. A consistent, contemporaneous, unedited history — calls, texts, and a simple log of what happened and when — is much harder to dispute than an isolated recording produced only when things go wrong.
Frequently asked questions
Do I have to tell my co-parent I am recording our calls in Indiana?
No. Because you are a party to the call, your own presence satisfies Indiana's rule. Telling the other person is not legally required, though some parents choose to mention it anyway to avoid a credibility fight later.
Can I record a conversation between my co-parent and our child?
Only if you are a party to that conversation. If you are recording a call between your co-parent and the child that you are not part of — for example, secretly recording the child's phone during a call you are not on — you fall outside the one-party exception and into the same territory as recording any other conversation you are not part of, which is a felony. This is a genuinely fact-specific question; talk to a family law attorney about your household's specific situation before doing this.
What if the call happened before I decided to document things?
The recording law only governs how you capture a communication going forward — it does not retroactively make an old, unrecorded conversation admissible. Start recording and logging from today, and preserve whatever authentic evidence (texts, emails, voicemails) already exists rather than trying to reconstruct old conversations from memory.
Does this rule apply to text messages too?
Text messages are not “intercepted” the same way a live call is — you already have lawful access to your own device and the messages sent to you. The bigger risk with texts in a custody case is authenticity: preserve the full thread with timestamps rather than a cropped image, since courts and opposing counsel routinely question edited screenshots.
