Dating while separated in SC is not illegal by itself, but the moment a new relationship becomes sexual, South Carolina treats it as adultery, and that single fact can wipe out your alimony, tilt property division against you, and hand your spouse a faster route to divorce. You remain fully married until a Family Court judge signs the final decree, and the law does not soften for spouses who have been living apart or who both want the marriage to end.
You Are Still Legally Married Until the Decree
South Carolina does not recognize a formal “legal separation.” What it recognizes is spouses living separate and apart without cohabitation, which for a full continuous year becomes the state’s only no-fault ground for divorce.1South Carolina Legislature. South Carolina Code 20-3-10 – Grounds for Divorce Throughout that year, and up until the final decree is entered, you are married in every legal sense. A temporary Order of Separate Maintenance and Support can address custody, visitation, and support during that period, but it does not dissolve the marriage.2South Carolina Legislature. South Carolina Code Title 20 Chapter 3 – Divorce
Because the marriage is still intact, sexual contact with anyone other than your spouse meets South Carolina’s definition of adultery. No exception exists for couples who have been apart for months or who have already agreed to divorce.
What Your Spouse Has to Prove
Your spouse does not need direct proof of the act itself. South Carolina courts use a circumstantial standard known as “inclination and opportunity.” Your spouse has to show that you had a romantic interest in someone (inclination) and the chance to act on it in private (opportunity). Romantic texts, dating app profiles, hotel receipts, overnight stays, and neighbor testimony that a person regularly spends the night have all been enough. Courts have found adultery proven when a spouse shared a hotel room or a cruise cabin with someone else, even where the spouse denied that anything happened.
Adultery also remains a criminal offense in South Carolina, carrying a fine of $100 to $500 and imprisonment from six months to one year.3South Carolina Legislature. South Carolina Code Title 16 Chapter 15 – Offenses Against Morality and Decency Prosecutions almost never happen. The damage you should worry about is civil.
You Can Lose Alimony Entirely
South Carolina law bars a spouse who commits adultery from receiving any alimony at all.4South Carolina Legislature. South Carolina Code 20-3-130 – Award of Alimony and Other Allowances The bar applies if the adultery occurs before the earlier of two events: the formal signing of a written property or marital settlement agreement, or the entry of a permanent order of separate maintenance and support. Notice what the cutoff is not. It is not the final divorce decree. The window of vulnerability closes well before the divorce ends, which surprises many people who assume separation itself is a safe zone.
Even when the outright bar does not apply, marital misconduct is one of the factors the court weighs in setting alimony amounts.4South Carolina Legislature. South Carolina Code 20-3-130 – Award of Alimony and Other Allowances If you would otherwise qualify for support, a new sexual relationship during separation can erase that income entirely.
Property Division Can Shift Against You
South Carolina divides marital property by “equitable apportionment,” meaning the court splits assets and debts in whatever proportion it considers fair. Marital misconduct is a named factor in that calculation when the misconduct affected the couple’s finances or contributed to the end of the marriage.5South Carolina Legislature. South Carolina Code 20-3-620 – Apportionment Factors
Conduct after any of three protective events cannot be used against you: entry of a pendente lite (temporary) order in the divorce action, formal signing of a written settlement agreement, or entry of a permanent order of separate maintenance and support.5South Carolina Legislature. South Carolina Code 20-3-620 – Apportionment Factors Before any of those events, dating that becomes adultery can move the split against you.
Money You Spend on a New Partner
A separate risk sits alongside the adultery question. If you spend marital funds on a new relationship, your spouse can argue you wasted marital assets. Dinners, trips, gifts, and rent for a new partner all come out of the marital estate, and courts can adjust the property division to compensate the other spouse. The spending does not have to be lavish. Until the divorce is final, most income earned during the marriage is marital property, so even spending “your own paycheck” on a new partner can create a claim.
Custody Effects Are Narrower But Real
Dating alone does not automatically shift custody. South Carolina courts decide custody by the child’s best interests, weighing factors that include the stability of each home, each parent’s ability to meet the child’s needs, and the quality of the parent-child relationship.6South Carolina Legislature. South Carolina Code 63-15-240 – Contents of Order for Custody Affecting Rights and Responsibilities of Parents; Best Interests of the Child
A new relationship becomes relevant when it destabilizes the child. Introducing a partner too early, overnight stays while children are present, exposing children to conflict with the other parent, or dating someone with a concerning background can all work against you. Judges who see a parent putting a new romance ahead of a child’s adjustment tend to view that unfavorably.
Moving In Together Ends Alimony
If dating turns into living together, the consequences get sharper. South Carolina law terminates alimony when the supported spouse engages in “continued cohabitation,” defined as residing with another person in a romantic relationship for 90 or more consecutive days.7South Carolina Legislature. South Carolina Code 20-3-150 – Segregation of Allowance Between Spouse and Children; Effect of Remarriage of Spouse Once cohabitation is proven, alimony stops and does not come back.
The statute also closes the obvious workaround. If a court finds that a supported spouse has been living with a partner in shorter stretches and periodically separating to avoid hitting 90 days, the court can still find that continued cohabitation exists.7South Carolina Legislature. South Carolina Code 20-3-150 – Segregation of Allowance Between Spouse and Children; Effect of Remarriage of Spouse
Your Spouse Gets a Faster Divorce
Proving adultery removes the one-year separation requirement.1South Carolina Legislature. South Carolina Code 20-3-10 – Grounds for Divorce Adultery is a fault ground, and fault cases can proceed without waiting out the full year. The minimum procedural timeline is three months from filing to a final decree.2South Carolina Legislature. South Carolina Code Title 20 Chapter 3 – Divorce A spouse who catches you dating gains both a faster exit and a stronger position in negotiations over money and property.
How to Reduce the Risk If You Date
The safest position is to wait until one of the statutory cutoff events has been entered: a signed written settlement agreement, a permanent order of separate maintenance and support, or in the case of property division, a pendente lite order. Once one of those is in place, later conduct falls outside what the court can use against you for the corresponding issue.
Until then, the practical guardrails follow from the rules above. Keep new relationships nonsexual. Keep marital money out of them. Do not stay overnight when children are with you, and do not introduce a new partner into the children’s lives while the case is unfolding. Do not move in together, and do not try to time cohabitation around the 90-day rule. If you are unsure where you stand, ask a South Carolina family lawyer before the relationship progresses, not after your spouse’s attorney has already gathered the texts and receipts.
