South Carolina has one rule that catches a lot of people off guard: marital misconduct can matter here in a way it doesn't in most states. It's an equitable distribution state — meaning courts divide marital property fairly, not automatically down the middle. But unlike states with strict no-fault frameworks, South Carolina still lets fault, including adultery, shape both property division and alimony. That single difference changes the financial calculus for a lot of South Carolina divorces.

Property Division: Equitable Distribution, Not Automatic 50/50
South Carolina divides marital property under S.C. Code § 20-3-620. Equitable distribution means courts divide assets in a way they consider fair — not necessarily equal. Family courts follow a four-step process: identify what counts as marital versus separate property, value the marital estate, apportion it according to the statutory factors, and then distribute it.
Marital property generally includes assets and debts acquired by either spouse from the date of marriage through the date the divorce action is filed — real estate, retirement accounts, vehicles, business interests, and joint debt. It doesn't matter whose name is on the title; property acquired during the marriage is typically treated as marital, regardless of who earned it. Separate property — what a spouse owned before marriage, inheritances, and gifts received individually — is generally excluded from division, unless it becomes commingled with marital funds or increases in value because of marital effort.
The 15 statutory factors under S.C. Code § 20-3-620 cover a wide range: each spouse's contribution to acquiring the property (including as a homemaker), the duration of the marriage, marital misconduct that affected the economic circumstances of the marriage, the income and earning potential of each spouse, physical and emotional health, the desirability of awarding the family home to the custodial parent, tax consequences, prior support obligations, liens and encumbrances, child custody arrangements, and any other factor the court finds relevant. There is no presumption of an equal split, though in long marriages outcomes often land near equal, and divisions more lopsided than 60/40 are relatively uncommon.
Suppose a couple has $420,000 in total marital assets: a home with $220,000 in equity, a 401(k) with $140,000, and $60,000 in joint savings. A judge starting from a rough midpoint might consider each spouse receiving around $210,000. But if one spouse depleted marital funds through an affair or gambling, or if one spouse gave up career growth to raise children, the court might shift the split to 55/45 or 60/40, or adjust which specific assets go to which spouse. Every outcome depends on how the 15 statutory factors apply to the specific facts of the marriage.

Alimony: Five Types, and an Adultery Bar That Changes Everything
South Carolina family courts can award alimony under S.C. Code § 20-3-130. The statute recognizes five distinct types: periodic alimony (ongoing monthly payments), rehabilitative alimony (a finite amount tied to a goal like finishing job training), lump-sum alimony (a fixed total, often paid in installments), reimbursement alimony (compensation for contributions like funding a spouse's degree), and separate maintenance and support (support ordered without a full divorce). There is no statutory formula — courts weigh 13 factors, including the length of the marriage, each spouse's income and earning potential, age and health, standard of living during the marriage, and marital fault.
The factor that sets South Carolina apart from most states is adultery. Under § 20-3-130(A), a spouse who commits adultery before the final property settlement or a permanent order of separate support is generally barred from receiving alimony — full stop. This bar applies regardless of financial need, how long the marriage lasted, or how the other statutory factors would otherwise weigh in that spouse's favor. It's one of the strictest fault-based alimony rules anywhere in the country.
Outside of the adultery bar, South Carolina alimony awards depend heavily on the specific facts of the marriage. Periodic alimony is the most common form and generally continues until the recipient remarries, dies, or cohabits with a romantic partner for 90 or more consecutive days — at which point it typically ends automatically. Rehabilitative alimony is tied to a specific purpose, like completing a degree or job training, and is structured to end once that goal is reached or a set event occurs.
Suppose Spouse A earns $7,500 per month and Spouse B earns $2,800 per month after an 18-year marriage, and Spouse B stepped back from a career to raise children. Without any fault in play, a court weighing the statutory factors might consider periodic alimony in a range that reflects the income gap and the standard of living during the marriage — for example, in the neighborhood of $1,200–$1,800 per month, though this is only illustrative. If Spouse B were shown to have committed adultery before the case settled, that same court would generally be barred from awarding any alimony to Spouse B at all, regardless of the income gap. This is an estimate only — actual outcomes vary by case.

Child Support: Income Shares Model, Updated in 2024
South Carolina calculates child support using the Income Shares Model under S.C. Code § 63-17-470. The model estimates what both parents would have spent on the child if the household hadn't split, combines both parents' gross monthly incomes, and matches that figure to a state guideline schedule administered by the Department of Social Services (DSS). Each parent then pays their proportional share based on their percentage of the combined income.
The DSS calculation starts with each parent's gross monthly income from all sources — wages, self-employment income, bonuses, and other regular income. Certain adjustments apply, such as health insurance premiums for the child and work-related childcare costs, which are added to the basic obligation and split proportionally. Custody arrangements matter too: when a parent has the child overnight for a significant share of the year, South Carolina's guidelines apply a shared custody adjustment that reduces the paying parent's obligation.
Suppose Parent A earns $6,000 per month and Parent B earns $2,500 per month, for a combined income of $8,500. For one child, the basic obligation from the current DSS schedule at that income level might land somewhere around $1,150 per month. Parent A's proportional share would be roughly 71% ($817/month) and Parent B's roughly 29% ($333/month). If the child lives primarily with Parent B, Parent A may pay the difference toward Parent B, with childcare and health insurance costs added and split proportionally on top. These figures are illustrative — the DSS calculator or a family law attorney can produce an exact estimate based on current numbers.

Retirement Accounts: QDROs and the Coverture Fraction
Retirement accounts accumulated during the marriage are marital property in South Carolina and subject to equitable distribution, while the portion earned before the marriage is generally treated as separate property. Courts commonly use a coverture fraction — the number of months of marriage that overlap with the retirement plan, divided by the total months in the plan — to identify the marital share of each account.
Dividing a 401(k), 403(b), or private pension typically requires a Qualified Domestic Relations Order (QDRO) — a court order directing the plan administrator to split the account. A properly executed QDRO allows the transfer to happen without triggering early withdrawal penalties or taxes at the time of the transfer. Without one, accessing retirement funds early can trigger significant tax consequences.
South Carolina Retirement System (SCRS) and Police Officers Retirement System (PORS) accounts — common for state employees, teachers, and law enforcement — are not divided using a standard private-sector QDRO. These state pension plans have their own qualified domestic relations order procedures administered through the South Carolina Public Employee Benefit Authority (PEBA), and the process differs from dividing a private 401(k). If a state pension is part of the marital estate, working with an attorney familiar with PEBA's specific requirements matters.
