Adultery Divorce in South Carolina: Rules, Evidence, and Alimony Impact

Filing for divorce on adultery grounds in South Carolina carries one of the most significant legal consequences in the state's family law system: a spouse proven to have committed adultery is permanently barred from receiving alimony. That single rule makes adultery the most strategically consequential divorce ground in South Carolina.

How Adultery Works as a Divorce Ground

Under S.C. Code Ann. § 20-3-10(1), adultery is one of four fault-based grounds for divorce. The key advantages over the no-fault separation ground:

• No separation period required — you can file immediately after discovering the affair
• Permanent alimony bar — the at-fault spouse cannot receive spousal support
• Can influence property division — courts may consider marital misconduct when dividing assets under equitable apportionment

The tradeoff: there's a mandatory 90-day waiting period between filing and the final decree (under S.C. Code Ann. § 20-3-80), and the evidence standard is demanding.

What Evidence You Need

South Carolina courts require proof of both "inclination" (desire to commit adultery) and "opportunity" (circumstances that made it possible). Courts accept two types of evidence:

Direct evidence: Text messages, emails, photographs, social media posts, hotel receipts, or testimony from someone who directly witnessed the affair.

Circumstantial evidence: A pattern of suspicious behavior combined with opportunity — late-night phone calls, unexplained absences, joint hotel check-ins, or a pattern of spending time alone with the alleged partner in private settings.

The standard is "preponderance of the evidence" (more likely than not), not "beyond a reasonable doubt." But single incidents of suspicious behavior typically won't meet the threshold. Courts look for a pattern.

Your corroborating witness requirement still applies — South Carolina law prohibits granting any divorce based solely on the spouses' own testimony. At least one independent witness must support the adultery allegations.

The Alimony Bar

This is where adultery ground becomes a strategic decision. Under South Carolina law, a spouse who committed adultery is permanently ineligible for alimony, regardless of financial need or the length of the marriage.

This matters most when:

• The at-fault spouse would otherwise qualify for significant alimony payments
• The marriage was long-term (courts award longer alimony for longer marriages)
• There's a large income disparity between spouses

If your spouse committed adultery and would likely seek alimony, filing on adultery grounds can save you thousands in future support obligations. Conversely, if you're the lower-earning spouse and your partner committed adultery, filing on this ground protects you from having alimony denied on other grounds.

The Condonation Defense

If you resumed cohabitation or sexual relations with your spouse after learning about the adultery, your spouse can raise the affirmative defense of "condonation" — forgiveness of the misconduct. If the court finds condonation occurred, you cannot obtain a divorce on adultery grounds.

This means timing matters. If you discover an affair, continuing to live together while you plan your filing can undermine your case. Consult with an attorney or start documenting your intent to separate immediately.

Habitual Drunkenness as a Fault Ground

South Carolina's fourth fault ground — habitual drunkenness or narcotics abuse (S.C. Code Ann. § 20-3-10(4)) — covers chronic substance abuse that caused the breakdown of the marriage.

"Habitual" is the critical word. Courts require evidence of a persistent, ongoing pattern — not a single DUI or a one-time incident. Useful evidence includes:

• Treatment facility records
• Multiple substance-related arrests
• Employment termination related to substance use
• Testimony from family, friends, or coworkers about the pattern
• Financial records showing money spent on substances

Like adultery, this ground skips the one-year separation but triggers the 90-day post-filing wait. Unlike adultery, a finding of habitual drunkenness does not automatically bar alimony — though courts may consider it when deciding alimony amounts and duration.

When to Choose Fault vs. No-Fault

File on fault grounds when the alimony bar matters, when you can't wait a year, or when fault findings will meaningfully affect property division negotiations. File no-fault when your goal is the simplest path to a decree and alimony isn't in dispute.
