Divorce Laws in South Carolina: Grounds, Property, and Custody

Divorce laws in South Carolina run through the Family Court system, and every case has to clear three gates before a judge signs a decree: residency, grounds, and process. If you’re going the no-fault route, plan on a full year of living apart before the court can act. If you’re filing on fault grounds, the ground you pick will shape not just whether the divorce is granted but how property gets divided and whether alimony is on the table at all.

Who Can File in South Carolina

Residency comes first. If both spouses live in the state, the one filing must have lived here for at least three months. If only one spouse lives in South Carolina, that spouse needs a full year of continuous residency before filing.¹

The clock runs backward from the filing date, not from separation. Recent arrivals to the state have to wait until they hit the one-year mark. The statute doesn’t define residency with a single test like voter registration or a driver’s license; courts look at whether you actually live here rather than parking a temporary presence long enough to file.

The Five Grounds for Divorce

South Carolina recognizes four fault grounds and one no-fault ground. You have to prove at least one.²

Adultery. Sexual intercourse with someone other than your spouse. Direct proof isn’t required; circumstantial evidence showing opportunity and inclination can be enough.
Desertion. One spouse left the marital home and stayed away for at least a year without justification or the other spouse’s consent.
Physical cruelty. Actual or threatened physical violence creating a genuine danger of harm.
Habitual drunkenness or drug use. A sustained pattern of alcohol or narcotic drug abuse, not a single incident.
One-year separation. The no-fault ground. Spouses have lived apart continuously for a year without cohabiting.

The ground matters beyond just getting the divorce granted. Fault findings feed directly into property division and alimony, which is why fault allegations often get litigated hard even when both spouses want out.

How Fault Changes the Financial Outcome

Marital misconduct is a factor the court weighs when dividing property, particularly if the misconduct affected the couple’s finances or contributed to the breakup.³ A spouse who drained marital funds on an affair can walk away with a smaller share of what’s left.

Alimony consequences are sharper. A spouse who committed adultery before either signing a written settlement agreement or getting a court order for separate maintenance is completely barred from receiving alimony.⁴ It isn’t a factor a judge weighs. It’s a disqualification. Timing matters: only pre-agreement or pre-order conduct triggers the bar.

The One-Year Separation Rule

The no-fault path requires spouses to live in physically separate residences for one continuous year.² Different bedrooms under the same roof does not count. Different homes.

The clock resets if you move back in together or resume sexual relations during the year. Courts usually want testimony or documentation nailing down the date separation began. If you can’t prove a full year of continuous separation, the judge will dismiss the no-fault petition, and you’ll either start over or refile on a fault ground.

Filing the Case

You file with the Clerk of Court in the county where your spouse lives, or where the two of you last lived together. The filing fee is $150.⁵ If you can’t afford it, you can ask the court to let you proceed in forma pauperis by motion.

The core papers include a Summons, a Complaint stating your grounds and the relief you want, and a Family Court Cover Sheet. You’ll also complete a Financial Declaration, which the court requires anytime finances are at issue.⁶ That form asks for gross monthly income, payroll deductions, monthly expenses, debts, and a full inventory of marital and nonmarital property.⁷ Total assets over $300,000 must be itemized in additional detail.

Your spouse must then be formally served through a process server or another authorized method. They have 30 days to file a written response.⁸ If nothing is filed, the case can proceed as a default, and the court typically grants what the filing spouse requested.

Mandatory Mediation Before Trial

South Carolina requires mediation for all contested issues before a family court matter can be tried.⁹ The case cannot even be placed on the trial calendar until a Proof of ADR is filed.¹⁰

A neutral mediator helps you negotiate on property, custody, and support. The mediator doesn’t decide anything; the goal is a voluntary settlement. Anything resolved in mediation folds into the final decree. Whatever’s unresolved goes to trial. Private mediators bill hourly, and rates vary with complexity and experience.

How Property Gets Divided

South Carolina uses equitable distribution, which means fair rather than automatically equal.³ A 50/50 split is one possible outcome. The judge has broad discretion to shift the division based on 15 statutory factors, including length of the marriage, each spouse’s income and earning potential, health, contributions to acquiring or preserving marital property (homemaking counts), the value of nonmarital property each spouse holds, vested retirement benefits, prior-marriage support obligations, tax consequences, liens and debts, child custody, and any marital misconduct that affected finances or contributed to the divorce.

Marital Property vs. Nonmarital Property

Only marital property gets divided. Marital property is essentially everything acquired during the marriage, regardless of whose name is on the title, with a few exceptions.¹¹ Nonmarital property, which the court cannot touch, includes:

Gifts or inheritances one spouse received from someone other than the other spouse.
Anything owned before the wedding.
Property acquired after a temporary order, written settlement agreement, or permanent support order.
Property excluded by a prenuptial agreement. A prenup is presumed fair when both spouses had separate attorneys and made full financial disclosure.

One trap catches people off guard. If nonmarital property increased in value during the marriage because of the other spouse’s efforts, the increase can be treated as marital. A business owned before the wedding that doubled in value because the other spouse helped run it could be partially subject to division. Gifts between spouses are always marital.

Splitting Retirement Accounts

Retirement benefits accumulated during the marriage are marital property, and vested retirement benefits are one of the court’s explicit statutory factors.³ Dividing a 401(k), pension, or similar employer plan requires a Qualified Domestic Relations Order, or QDRO. That’s a separate court order directing the plan administrator to transfer a portion of the account to the other spouse.¹²

Federal law generally prohibits assigning someone else’s retirement benefits, and a QDRO is the narrow exception. Without a properly drafted QDRO on file with the plan administrator, the division ordered in your decree won’t actually happen. Don’t wait. If your ex withdraws funds, remarries, or dies before the QDRO is on file, you can lose your share.

Alimony

Alimony in South Carolina comes in several forms, each built for a different situation.⁴

Periodic alimony. Ongoing payments that end on the recipient’s remarriage, cohabitation with a new partner, or the death of either spouse. Modifiable if circumstances change.
Rehabilitative alimony. Time-limited support to help a spouse become self-sufficient, often tied to education or job training. Modifiable if good-faith efforts are frustrated by unforeseen events.
Lump-sum alimony. A fixed total paid at once or in installments. Not modifiable, and it doesn’t end on remarriage.
Reimbursement alimony. Compensates a spouse who supported the other through education or career development expecting to share in the increased earnings.

The court weighs 13 factors when setting alimony, including length of the marriage, each spouse’s health, education, earning potential, standard of living during the marriage, current and anticipated income and expenses, custody arrangements, marital misconduct, and tax consequences.⁴ How the judge weights those factors is up to the judge, which means outcomes vary even in cases with similar numbers.

And again: adultery before a settlement agreement or support order completely disqualifies a spouse from receiving alimony. It’s the single biggest reason fault fights turn expensive.

Child Custody

When minor children are involved, custody follows the best-interest-of-the-child standard, backed by 17 statutory factors.¹³ The court looks at each parent’s capacity to meet the child’s needs, the child’s existing relationships with each parent and siblings, each parent’s willingness to support the child’s relationship with the other parent, and the stability of each proposed arrangement.

Some factors carry particular weight. Courts pay close attention to attempts to manipulate a child against the other parent, any history of domestic violence or abuse, and relocations of more than 100 miles from the child’s primary home in the past year without a safety-related reason. The child’s own preferences are considered, though the statute doesn’t set an age at which those preferences become controlling.

A parent’s disability, on its own, cannot decide custody. The court can consider a disability only to the extent it affects whether the proposed arrangement serves the child’s best interest.

Child Support

South Carolina calculates child support under the Income Shares Model. It estimates what parents would have spent on the child if still together, then splits that between them in proportion to income.¹⁴ Gross monthly income includes wages, bonuses, commissions, rental income, retirement benefits, and most other sources. The court uses a schedule to find the basic obligation for the combined income and number of children.

On top of that, the court adds the child’s share of health insurance premiums and work-related childcare costs. The total is split by income share. If a parent is voluntarily unemployed or underemployed, the court can impute income based on what that parent could earn at full capacity.

Child support obligations in South Carolina can begin as early as the date of conception, with the biological father responsible for child support and half of the mother’s pregnancy expenses.¹⁵

Orders While the Case Is Pending

Divorce takes months, sometimes longer. The court can issue temporary (pendente lite) orders covering support, custody, and use of the marital home in the meantime. Those orders address who pays the mortgage, who has primary custody, and whether either spouse gets temporary alimony. The court can also enter a temporary restraining order to keep either spouse from dissipating marital assets.

Temporary orders stay in place until the final decree replaces them. They aren’t automatic. You or your attorney has to request them by motion. The court applies the same standards as at final judgment, just with less complete information.

Attorney Fees, Name Changes, and Tax Notes

The court can order one spouse to pay the other’s attorney fees, expert fees, investigation costs, and other litigation expenses, weighing both parties’ finances and marital fault.¹⁶ Fee awards can cover work done before the case was filed, during it, and after judgment, and they create a lien on the property of the spouse ordered to pay.

The final decree can also allow either party to resume a former surname or the surname of a prior spouse.¹⁷ You have to request it in your complaint or counterclaim. The court won’t do it on its own. Once the decree includes the name change, that’s your legal basis for updating your driver’s license, Social Security records, and other identification.

Two federal tax rules matter in almost every case with real money involved. Alimony paid under agreements executed after 2018 is not tax-deductible for the paying spouse, and the receiving spouse does not report it as income.¹⁸ Alimony now comes entirely from after-tax dollars, which changes the negotiation math. And if you sell the marital home, the federal capital gains exclusion lets you exclude up to $250,000 in gain as a single filer, or $500,000 if you file jointly for the year of the sale, provided you generally owned and lived in the home for at least two of the five years before the sale.¹⁹ Timing the sale around the divorce can determine which exclusion you qualify for.
