Grounds for Divorce in SC: Fault vs. No-Fault Explained
By Mary Ann Hall, Hall & Means, LLC
South Carolina recognizes five grounds for divorce in South Carolina, and the choice between them affects far more than just the timeline of your case. It can determine whether you qualify for alimony, how property is divided, and how contentious the proceedings become. The most important thing to understand upfront: South Carolina does not have a simple “irreconcilable differences” ground. The closest equivalent is a mandatory one-year separation period—and that one requirement sets SC divorce law apart from the majority of states.
The Five Grounds for Divorce in South Carolina
SC Code § 20-3-10 lists the only grounds on which a South Carolina court may grant an absolute divorce:
- Adultery — voluntary sexual conduct by either spouse with someone other than the other spouse (the standard applies to same-sex marriages as well), proven by circumstantial evidence establishing both opportunity and inclination
- Desertion for one year — one spouse willfully abandons the other without justification and without consent
- Physical cruelty — actual personal violence, or conduct that creates a reasonable apprehension of bodily harm and makes continued cohabitation unsafe
- Habitual drunkenness — a fixed habit of excessive intoxication by alcohol or narcotics; a single incident is insufficient
- One year of continuous separation — both spouses have lived separate and apart without cohabitation for at least one year (the only no-fault ground)
Grounds 1 through 4 are fault-based. Ground 5 is no-fault. The vast majority of divorces in Charleston County are filed on the one-year separation ground—because it requires no proof of wrongdoing and because it is the only ground that neither spouse can contest once the separation period is complete.
What Is the Difference Between Fault and No-Fault Divorce in SC?
In a fault divorce, the petitioning spouse must prove—with evidence—that the other spouse committed one of the four fault acts. Adultery must be proven by circumstantial evidence establishing both opportunity and inclination (direct evidence is rarely available and rarely required). Physical cruelty must be supported by specific incidents, not general claims of a bad marriage. The bar for proof is lower than a criminal trial but higher than simply saying it happened.
In a no-fault divorce, neither party has to prove the other did anything wrong. The only requirement is demonstrating that both spouses lived separate and apart for at least one continuous year. There is no requirement that both spouses agree to the divorce—one spouse can file unilaterally once the year is up, and the other spouse cannot legally prevent the divorce from being granted.
The No-Fault Ground: What “One Year of Separation” Actually Means
South Carolina’s one-year separation requirement has specific rules that trip up many people who try to navigate it without legal guidance.
When does the one-year clock start?
The clock starts on the date one spouse physically moves out of the marital home. South Carolina law requires that spouses live separate and apart — meaning under different roofs. Staying in the same home in separate bedrooms does not qualify, and a single night under the same roof restarts the entire one-year clock from that date. If you intend to use the no-fault ground, physical separation is non-negotiable.
Does the year have to be continuous?
Yes. If the spouses resume cohabitation—even briefly—the clock resets. A single night of reconciliation restarts the year from that date. This is a significant trap: couples who attempt to reconcile and then separate again must run the full 12-month clock from the most recent date of separation before they can file.
Does the other spouse have to agree?
No. Once one year of continuous separation is complete, either spouse may file for divorce, and the Family Court will grant the divorce even if the other spouse objects. The other spouse cannot prevent the divorce by refusing to participate or by denying the separation occurred—though they may contest the date of separation, which can matter for property division and alimony calculations.
Fault-Based Grounds: When Do They Actually Matter?
Most Charleston family law attorneys advise filing on the no-fault ground when the separation year has run—it is cleaner, faster, and cheaper. Fault grounds are worth considering in three specific situations:
Adultery and alimony: the stakes are high
Under SC Code § 20-3-130(A), a spouse who commits adultery before the earliest of (1) signing a written property or marital settlement agreement or (2) a permanent order of separate maintenance is barred from receiving alimony. If your spouse committed adultery and you want to preserve your right to alimony, you can choose to file on the adultery ground or on the no-fault ground while preserving the adultery evidence to defeat any claim they make for alimony from you. Conversely, if you committed adultery, you cannot receive alimony regardless of which ground is used.
Proving adultery requires circumstantial evidence showing both opportunity (the spouse had access to be alone with the other person) and inclination (a romantic or sexual interest). Text messages, hotel records, and witness testimony are common forms of evidence. Direct proof of the sexual act is not required but is obviously compelling when available.
Physical cruelty: when you cannot wait a year
Physical cruelty is one of the few fault grounds that allows you to file for divorce without waiting. If your spouse has physically abused you, and you have documentation (police reports, medical records, protective orders), you may be able to proceed on this ground immediately rather than waiting the full year. You will still need to prove the cruelty at a hearing—it is not enough to allege it.
Habitual drunkenness: a tool for custody and property arguments
Habitual drunkenness requires proof of a persistent pattern—not a single incident or occasional excess. Documentation through DUI records, employer discipline, medical records, witness testimony, and rehab history is typically required. When proven, it affects not only the divorce itself but also custody (courts take substance abuse very seriously in the best-interests analysis) and can influence equitable distribution arguments about who dissipated marital assets.
Should You File on Fault or No-Fault Grounds?
For most clients in Charleston, the answer is no-fault — once the year is up. Here is the framework for deciding:
- File no-fault if: the separation year has run, alimony is not a major issue, you want to minimize court conflict, or you simply want the divorce done efficiently
- Consider fault if: alimony is at stake and adultery is provable, you need to file immediately due to physical cruelty, or fault evidence is strong and will meaningfully change the financial outcome
- Avoid fault grounds if: the evidence is weak, the conduct is more emotional cruelty than legal cruelty, or the cost of litigating fault (discovery, depositions, contested hearings) will exceed what you gain
How Does the Ground for Divorce Affect Property Division and Alimony?
Property division in South Carolina is governed by equitable distribution under SC Code § 20-3-620, which lists 15 factors the court weighs. Fault is one of those factors—specifically, “the conduct of each spouse during the marriage”—but it is not a trump card. Courts will not massively shift property division to punish an adulterous spouse, but egregious fault (hiding assets, dissipating marital funds on an affair) can meaningfully affect the result.
Alimony is where fault has its sharpest teeth. Adultery committed before a written settlement agreement or a permanent order of separate maintenance bars alimony for the guilty spouse under § 20-3-130(A). Other fault grounds (cruelty, drunkenness) factor into the court’s alimony analysis as part of the “marital misconduct” consideration under § 20-3-130(C)(10), but they do not automatically bar or guarantee alimony the way adultery does.
Frequently Asked Questions
Can I file for divorce in South Carolina before the one-year separation is complete?
Only on a fault ground. If you can establish adultery, physical cruelty, habitual drunkenness, or one year of desertion, you may file without waiting. If you are using the no-fault ground, the full year of continuous separation must be complete before the divorce complaint is filed—not just before the hearing date.
Does South Carolina have irreconcilable differences as a divorce ground?
No. SC Code § 20-3-10 does not include irreconcilable differences or incompatibility. The practical equivalent is the one-year separation ground, but it requires a full year of continuous, documented separation before you can file. Many people are surprised by this when they move to South Carolina from states that allow immediate no-fault filing.
Does it matter who files first for divorce in South Carolina?
Generally no. The petitioner (the spouse who files first) goes first at trial, which has minor tactical implications, but South Carolina does not favor the petitioner over the respondent in property division, alimony, or custody decisions. Filing first does not give you a legal advantage in substantive matters.
Can my spouse stop the divorce by refusing to cooperate?
No. Under the no-fault ground, a spouse cannot prevent the divorce once the one-year separation is complete and properly documented. The court will enter a default judgment if the respondent refuses to participate. Under fault grounds, the respondent can contest the factual basis for the fault allegation, which adds time and expense.
