Lump sum alimony in South Carolina is a fixed, finite total sum of spousal support paid in one installment or over a set schedule under S.C. Code § 20-3-130(B). Unlike periodic alimony, it cannot be modified for changed circumstances or remarriage and terminates only on the supported spouse's death.

What Is Lump Sum Alimony in South Carolina?
Lump sum alimony in South Carolina is a finite, predetermined total amount of spousal support that one spouse pays the other, either in a single payment or over a fixed installment schedule. Under S.C. Code § 20-3-130(B)(2), this award terminates only upon the death of the supported spouse and cannot be reduced, increased, or canceled based on remarriage or future changed circumstances.
This form of support stands apart from the four other recognized categories because of its permanence and certainty. The dollar figure is locked in at the time of the divorce decree. A spouse ordered to pay $120,000 in lump sum alimony owes exactly $120,000 regardless of whether the receiving spouse remarries the following month or the paying spouse loses a high-paying job. South Carolina family courts treat the obligation as a vested property right once the final order is entered, which is precisely why many divorcing couples negotiate it as part of a comprehensive settlement rather than leaving the support question open to lifelong adjustment.
The Four Types of Alimony Under South Carolina Law
South Carolina recognizes four primary types of alimony under S.C. Code § 20-3-130(B): periodic, rehabilitative, lump sum, and reimbursement. Lump sum alimony is the only category, alongside reimbursement, that is completely non-modifiable. Courts may award more than one type in a single case, and judges exercise broad discretion in choosing the structure.
Understanding where lump sum alimony fits requires comparing all four forms. Periodic alimony is the most common and most favored award, consisting of ongoing monthly payments that continue until the recipient's death, remarriage, or continued cohabitation of 90 or more consecutive days. Rehabilitative alimony provides time-limited support while a spouse gains education or job skills and can be modified if good-faith efforts to become self-supporting are frustrated. Reimbursement alimony repays a spouse who funded the other's degree or career advancement. Lump sum alimony, by contrast, delivers a single fixed dollar amount that ends only at death, giving both parties financial finality.
| Alimony Type | Payment Structure | Modifiable? | Terminates On |
|---|---|---|---|
| Periodic | Ongoing monthly | Yes (changed circumstances) | Death, remarriage, 90-day cohabitation |
| Rehabilitative | Fixed sum, installments | Yes (frustrated efforts) | Remarriage, cohabitation, death, set event |
| Lump Sum | One payment or fixed schedule | No | Death of supported spouse only |
| Reimbursement | Fixed sum, installments | No | Remarriage, cohabitation, death |
How Is Lump Sum Alimony Calculated in South Carolina?
Lump sum alimony in South Carolina has no formula or percentage calculation. Family court judges set the amount using pure discretion, weighing 13 statutory factors listed in S.C. Code § 20-3-130(C). A 2023 South Carolina Bar survey found that awards for similar fact patterns varied by as much as 40% depending on the judicial circuit.
Because no guideline calculation exists, parties and judges often build a lump sum figure by estimating what periodic alimony would total over an expected support period, then discounting to present value. For example, if periodic support of $1,500 per month would reasonably continue for ten years, the projected stream equals $180,000 before adjusting for the time value of money and the recipient's loss of future modification rights. The 13 factors the court must weigh include the duration of the marriage, the ages and health of both spouses, each spouse's earning capacity and employment history, the standard of living established during the marriage, the marital and nonmarital property awarded to each party, marital misconduct or fault, and tax consequences. No single factor controls, which is why outcomes vary so widely across cases and why negotiated lump sum vs monthly alimony decisions are common.
Lump Sum vs Monthly Alimony: Which Is Better?
Lump sum vs monthly alimony involves a trade-off between certainty and flexibility. A one time alimony payment gives the recipient guaranteed money that survives the payer's job loss or death and cannot be cut if they remarry. Monthly periodic alimony offers lower upfront cost but remains modifiable and ends on remarriage or 90-day cohabitation.
The decision turns on each party's priorities and risk tolerance. For the supported spouse, a buyout alimony arrangement eliminates collection risk, removes the payer's ability to petition the court for a reduction, and is not terminated by the recipient remarrying, an enormous advantage for someone who anticipates a new relationship. For the paying spouse, a lump sum delivers a clean financial break, ends any future court involvement, and caps total liability at a known number rather than an open-ended monthly obligation that could last decades. The primary downside of a one time alimony payment is liquidity: the payer must have access to substantial cash or assets, often funded through a property buyout, retirement account transfer, or refinancing of the marital home, at the moment of divorce rather than spreading the cost over years.
Alimony Buyout Agreement: Structuring a Property-Based Settlement
An alimony buyout agreement converts a future support obligation into a one-time transfer of cash or property, often the marital home equity or a retirement account share. Under S.C. Code § 20-3-130(B)(2), lump sum alimony may be paid in one installment or periodically over a fixed period, and parties may agree in writing, with court approval, to make it nonmodifiable.
In practice, an alimony buyout agreement frequently appears inside a broader marital settlement agreement that also resolves equitable distribution. A common structure assigns the supported spouse a larger share of the home equity or an additional portion of a 401(k) via a Qualified Domestic Relations Order in exchange for waiving ongoing periodic support. This approach can carry tax advantages, because property transfers between spouses incident to divorce are generally not taxable events under federal law, whereas a cash lump sum may have different treatment. The agreement must be reduced to writing, signed by both parties, and approved by the family court to be enforceable and to lock in nonmodifiability. Couples pursuing a buyout alimony structure should obtain independent legal and tax advice, because once the court approves the agreement, neither party can later return to modify the amount.
Tax Treatment of Lump Sum Alimony in South Carolina
Lump sum alimony in South Carolina is generally not deductible by the payer and not taxable income to the recipient for any divorce or separation agreement executed after December 31, 2018. This follows the federal Tax Cuts and Jobs Act of 2017, which eliminated the alimony deduction for agreements finalized in 2019 and later.
The tax change reshaped how parties structure spousal support nationwide, including in South Carolina. For divorces finalized before January 1, 2019, alimony payments remained deductible to the payer and taxable to the recipient under the prior rules, and those older orders retain their original tax treatment unless modified to expressly adopt the new law. For agreements signed in 2019 through 2026 and beyond, a one time alimony payment moves money without creating a federal income tax deduction or inclusion. South Carolina conforms to the federal treatment for state income tax purposes. Because a buyout alimony arrangement is often funded by transferring property rather than cash, and because property transfers incident to divorce are typically tax-free, the structure of the payment can significantly affect the after-tax value each spouse actually receives. Always consult a tax professional before finalizing any alimony buyout agreement.
Can Lump Sum Alimony Be Modified or Terminated in South Carolina?
Lump sum alimony in South Carolina cannot be modified or terminated based on changed circumstances or the recipient's remarriage. Under S.C. Code § 20-3-130(B)(2), the only event that ends the obligation is the death of the supported spouse, and even then the unpaid balance may be enforceable against the payer's estate depending on the order's terms.
This non-modifiable nature is the defining legal feature of a one time alimony payment and the reason it is treated more like a property award than ongoing support. A paying spouse who later experiences a job loss, disability, or significant income reduction has no statutory right to ask the court to reduce a lump sum obligation, unlike periodic or rehabilitative alimony, both of which can be modified on a showing of a substantial change in circumstances. Likewise, if the receiving spouse remarries or begins cohabiting within the 90-day statutory window, the lump sum is unaffected, whereas periodic alimony would terminate. This permanence cuts both ways: it protects recipients from future reductions while binding payers to a fixed number. Because the award is locked at the divorce decree, careful negotiation before signing is essential.
The Adultery Bar and Fault in South Carolina Alimony Awards
South Carolina law absolutely bars alimony, including lump sum alimony, for a spouse who commits adultery before the earliest of a signed written property settlement or a permanent order of separate maintenance. This prohibition appears in S.C. Code § 20-3-130(A) and applies regardless of how long the marriage lasted or the supported spouse's financial need.
The adultery bar is one of the strictest fault provisions in American family law and directly affects whether a spouse can receive any lump sum award. If the family court finds that a spouse committed adultery before the cutoff event, that spouse is permanently disqualified from receiving alimony of any type, and the bar applies even if both spouses committed adultery. Marital misconduct is also one of the 13 statutory factors a judge weighs when setting the amount of any alimony that is awarded, so conduct short of adultery, such as physical cruelty or financial misconduct, can still reduce or increase an award. Because the timing of the cutoff matters so much, the precise date a settlement agreement is signed or a separate maintenance order is entered can determine whether post-separation dating disqualifies a spouse from a buyout alimony arrangement entirely.
Filing Fees, Residency, and the Divorce Process in South Carolina
The family court filing fee for divorce in South Carolina is $150, charged as a flat fee in every county when you file the summons and complaint. As of June 2026, verify with your local clerk. To file, the plaintiff must meet the residency requirement under S.C. Code § 20-3-30: one year if only one spouse lives in the state, or three months if both spouses are South Carolina residents.
Beyond the filing fee, divorcing spouses should budget for several additional costs that affect the total expense of resolving alimony. Service of process through a sheriff's deputy runs $50 to $75, while a private process server charges $75 to $125. Couples with minor children must complete a mandatory parenting class costing $50 to $150. South Carolina requires mediation for all contested family court cases under the state Alternative Dispute Resolution Rules, with mediators charging $100 to $350 per hour and total mediation often running $300 to $2,000. An uncontested divorce in South Carolina typically costs around $3,000, while a contested case averages roughly $12,600. Spouses who cannot afford the filing fee may request a waiver using Form SCCA/400, the Motion and Affidavit to Proceed In Forma Pauperis, available to households earning below 125% of federal poverty guidelines.
Pending 2025-2026 Alimony Reform Legislation
As of June 2026, three South Carolina bills, House Bills 3074, 3078, and 3098, propose major changes to alimony law, but none has passed. These measures would limit or eliminate permanent periodic alimony and tie support duration to the length of the marriage, potentially reshaping how lump sum and other awards are structured.
House Bill 3098 would eliminate permanent periodic alimony and instead calculate support at one year of payments for every three years of marriage, terminating on cohabitation, Social Security retirement age, or death, and would make awards modifiable on changed circumstances. House Bill 3074 proposes the most restrictive framework, limiting periodic alimony to marriages lasting at least 15 years and capping support at 40% of the marriage length for unions of 5 to 10 years and 50% for marriages of 10 to 20 years. House Bill 3078 would allow alimony in certain adultery cases and proposes a formula of 30% to 35% of the income difference between spouses. All three bills strengthen the cohabitation rule, creating a rebuttable presumption that support ends after 90 or more consecutive days of cohabitation. Most analysts expect any reform to apply prospectively, meaning existing lump sum orders would remain undisturbed.
