South Carolina is a one-party consent state: if you are a party to a call or conversation, you may record it without telling the other person.
A recording you took part in is generally admissible in a South Carolina family court matter, subject to the judge's discretion on relevance and how it was obtained. Recording a conversation you are not part of falls outside the consent exception.

Short answer: yes, if you are a party to the call
South Carolina is a one-party consent state. If you are taking part in a phone call, an in-person conversation, or an electronic exchange, you may record it without telling anyone else on the line. For a parent trying to keep an honest, dated record of a co-parenting relationship, that means you do not need to ask permission before you press record on your own conversations.
The statute and how it is written
South Carolina's interception law sits in Title 17, Chapter 30 of the state code, the “Interception of Wire, Electronic, or Oral Communications” chapter. S.C. Code Ann. § 17-30-30 spells out the consent exception directly: it is lawful for a person not acting under color of law to intercept a wire, oral, or electronic communication where that person is a party to the communication, or where one of the parties has given prior consent to the interception. That single sentence is the entire basis for South Carolina's one-party rule — your own presence on the call, or another party's advance consent, is enough.
The penalty for getting it wrong
The consent exception only protects communications you are actually part of. Recording a conversation between two other people — hiding a device in a room, tapping a line you are not on, or asking someone else to secretly capture a conversation for you — falls outside § 17-30-30 and is a crime. Under S.C. Code Ann. § 17-30-50, a violation of the interception provisions is punishable by up to five years in prison and a $5,000 fine, with a reduced penalty for certain first-offense radio-related violations that do not apply to ordinary phone calls or in-person conversations. None of that exposure applies to a call or conversation you are lawfully a party to. Beyond the criminal penalty, S.C. Code Ann. § 17-30-135 also gives the person whose communication was unlawfully intercepted a civil claim: actual damages, or liquidated damages of $500 per day of violation, or $25,000, whichever is greater, plus punitive damages and attorney's fees. That civil exposure is a further reason to be certain you are actually a party to a conversation before you record it — and a further reason it is not worth the risk to secretly record a conversation between other people.
Using a recording in a South Carolina custody case
A recording you made as a participant is generally admissible in a South Carolina family court matter in the sense that the state's recording law does not stand in the way of it. Whether the judge actually admits and relies on it is a separate question that turns on relevance, whether the recording is a complete and unaltered original, and how it was obtained. Keep the full file rather than a trimmed clip, note the date and who was on the call, and avoid any editing — a recording that has been cut down to just the worst moment tends to raise more questions about your credibility than it answers about your co-parent's behavior.
The interstate caveat: what if your co-parent lives elsewhere?
South Carolina's one-party rule covers a call made from South Carolina, but if your co-parent is in an all-party consent state — California, Florida, Illinois, Pennsylvania, and several others — the cautious, generally accepted practice is to follow the stricter rule for the whole call: announce that you are recording, or otherwise be sure every party knows. Which state's law would actually govern a specific interstate call is a fact-specific legal question that depends on where each person was located and how a court chooses to apply the conflict, not something a general guide can settle for your situation. If your calls with your co-parent regularly cross state lines, confirm the current rule with a licensed attorney before relying on an unannounced recording.
How to document it so it holds up
A single recording rarely wins a custody case on its own. The strongest record is boring and consistent: preserve full call recordings and complete text threads rather than trimmed excerpts, attach reliable dates and times to everything, and keep copies somewhere your co-parent cannot alter or delete. A continuous, time-stamped history of missed exchanges, disparaging messages, and broken agreements carries far more weight with a South Carolina family court than one dramatic clip presented in isolation. Judges in contested custody matters tend to reward the parent who shows up with an organized, factual timeline rather than the parent who shows up with the loudest single recording.
Frequently asked questions
Do I have to tell my co-parent I am recording our calls in South Carolina?
No. Because you are a party to the call, your own consent is enough under § 17-30-30. Announcing it is not legally required, though some parents do it anyway to head off any later dispute about how the recording was made.
What if I want to record a conversation I am not part of, like between my child and my co-parent?
If you are not a party to that conversation and no party has given prior consent, recording it falls outside the exception and carries the same felony exposure as intercepting any other private conversation. This is a genuinely fact-specific question when a child is involved — talk to a family law attorney about your household before you do this.
Can I use a recording made in another state if my South Carolina custody case is heard here?
This depends on where the call actually took place, or where each party was located, and how the specific court handles the conflict — not simply on where the case is filed. Confirm this with a licensed attorney before relying on an out-of-state recording in a South Carolina proceeding.
Does the one-party rule apply to voicemails too?
Voicemails are generally treated differently from a live conversation, since the person leaving the message knows a recording device is capturing it. Save the original audio file rather than only a transcript, and preserve it the same way you would a call recording: unedited, dated, and backed up somewhere your co-parent cannot delete it.
