Yes, alimony can be changed in South Carolina under specific circumstances. Periodic and rehabilitative alimony are modifiable when either party demonstrates a substantial, unanticipated change in circumstances such as job loss, serious illness, retirement, or significant income changes. Under S.C. Code § 20-3-170, either spouse may petition the family court to increase, decrease, or terminate alimony payments. The filing fee for a modification petition is $150 as of May 2026. Lump-sum and reimbursement alimony cannot be modified once ordered. The requesting party bears the burden of proving changed circumstances by a preponderance of the evidence.

What Types of Alimony Can Be Modified in South Carolina
South Carolina recognizes four types of alimony, but only two are modifiable after the divorce is finalized. Under S.C. Code § 20-3-130(B), periodic alimony and rehabilitative alimony can be modified upon showing changed circumstances, while lump-sum and reimbursement alimony are fixed and cannot be changed by the court. Understanding which type of alimony your order contains determines whether alimony modification South Carolina courts will consider is even possible in your case.
Modifiable Alimony Types
Periodic alimony represents ongoing monthly payments designed to maintain the supported spouse's standard of living. Under S.C. Code § 20-3-130(B)(1), permanent periodic alimony is terminable and modifiable based upon changed circumstances occurring in the future. This is the most common form of alimony in South Carolina divorces and provides the most flexibility for either party to request changes.
Rehabilititative alimony provides temporary support while the recipient spouse gains education, training, or experience to become self-supporting. Under S.C. Code § 20-3-130(B)(3), rehabilitative alimony is modifiable based upon unforeseen events frustrating the good faith efforts of the supported spouse to become self-supporting or the ability of the supporting spouse to pay. For example, if a recipient spouse enrolled in nursing school but developed a disability preventing completion, the court could extend rehabilitative alimony.
Non-Modifiable Alimony Types
Lump-sum alimony consists of a fixed total amount, whether paid all at once or in installments. Under S.C. Code § 20-3-130(B)(2), lump-sum alimony is not terminable or modifiable based upon remarriage or changed circumstances in the future. Once ordered, the paying spouse must complete all payments regardless of any changes in either party's situation.
Reimbursement alimony compensates a spouse who supported the other through education or career advancement during the marriage. Under S.C. Code § 20-3-130(B)(4), reimbursement alimony is terminable on remarriage or continued cohabitation but is not modifiable based upon changed circumstances in the future. The amount reflects actual contributions made during the marriage and cannot be adjusted.
Proving Substantial Change in Circumstances
South Carolina courts require the party seeking alimony modification to prove a substantial, unanticipated change in circumstances by a preponderance of the evidence. Under S.C. Code § 20-3-170, the court must consider both the changed circumstances and the financial ability of the supporting spouse when deciding whether to modify alimony. The change must have been unanticipated at the time of the original divorce decree and must significantly affect either party's financial situation.
Changes That May Qualify for Modification
Job loss or significant income reduction constitutes a common basis for seeking to reduce spousal support in South Carolina. If the paying spouse is laid off, their business fails, or they experience an involuntary salary reduction of 20% or more, courts may reduce alimony obligations. Similarly, if the receiving spouse obtains substantially higher income, the paying spouse may petition to decrease or terminate payments.
Serious illness or disability affecting either spouse's earning capacity or expenses can justify modification. A decline in health of the supporting spouse that results in decreased income, decreased net worth, or increased medical expenses may warrant reduction. Conversely, if the supported spouse develops a serious illness requiring additional care, they may seek an increase in alimony payments.
Retirement by the paying spouse is specifically recognized under S.C. Code § 20-3-170(B) as sufficient grounds to warrant a hearing on whether to reduce or terminate alimony. The court considers the age of both parties, whether retirement decreases the paying spouse's income, whether retirement is voluntary, and whether retirement was contemplated at the time of the initial order.
Inheritance received by either spouse may provide grounds for modification. If the supported spouse receives money from an inheritance, a judge could terminate or reduce the amount of alimony they receive. Conversely, if the paying spouse inherits substantial assets, the recipient may seek increased support.
Changes That Typically Do NOT Qualify
Anticipated events that both parties knew would occur generally do not justify modification. For example, South Carolina courts have held that a spouse returning to work after children are grown was foreseeable at the time of divorce and declined to modify alimony on that basis. Voluntary income reduction, such as quitting a job without cause or taking early retirement when not financially necessary, may not justify reducing payments.
Temporary setbacks that resolve quickly typically do not warrant permanent modification. A brief period of unemployment followed by comparable re-employment may not demonstrate the substantial change courts require. The requesting party must show the change is ongoing or permanent rather than a temporary disruption.
How to File for Alimony Modification in South Carolina
Filing for alimony modification South Carolina requires submitting a petition to the same family court that issued the original divorce decree. The filing fee is $150 as of May 2026, with additional costs for process service ranging from $50 to $125. Either spouse may initiate the modification process, and the modification becomes effective no earlier than the date the petition is filed, even if the change in circumstances occurred before that date.
Step-by-Step Filing Process
First, obtain the proper forms from the South Carolina Judicial Branch website or your local family court clerk's office. You will need to file a Motion to Modify Alimony and supporting documentation proving your changed circumstances. Include financial declarations, pay stubs, tax returns, medical records, or other evidence supporting your request.
Second, file your petition with the family court clerk in the county where the original divorce was granted. Pay the $150 filing fee or submit Form SCCA/400 (Motion and Affidavit to Proceed In Forma Pauperis) if your household income falls below 125% of the federal poverty level, which is $19,500 for an individual in 2026.
Third, serve your former spouse with copies of all filed documents. You may use the county sheriff for $50-$75 or a private process server for $75-$125. Your spouse has 30 days to file a response contesting or agreeing to the modification request.
Fourth, attend the modification hearing where both parties present evidence. The judge will consider financial documents, testimony, and the circumstances of both parties before issuing a ruling. If you and your spouse agree on the modification, you may submit a consent order for the court to approve without a full hearing.
Required Documentation
Gather comprehensive financial documentation including three years of tax returns, six months of pay stubs, bank statements, retirement account statements, and documentation of monthly expenses. If seeking modification based on health issues, obtain medical records and physician statements detailing how the condition affects earning capacity.
For retirement-based modifications, provide pension statements, Social Security benefit calculations, and evidence that retirement was not anticipated at the time of divorce. If claiming the recipient spouse has increased income or cohabitation, gather employment records, social media evidence, or witness statements supporting your claims.
Automatic Termination of Alimony in South Carolina
South Carolina law provides for automatic termination of alimony under specific circumstances without requiring a modification petition. Under S.C. Code § 20-3-130(B)(6), periodic alimony terminates upon the death of either spouse, remarriage of the supported spouse, or continued cohabitation with a romantic partner for 90 or more consecutive days. Understanding these automatic termination events can save the paying spouse from continuing unnecessary payments.
The 90-Day Cohabitation Rule
Continued cohabitation means the supported spouse resides with another person in a romantic relationship for a period of 90 or more consecutive days under South Carolina law. Unlike remarriage, which automatically terminates alimony, cohabitation requires the paying spouse to file a petition and prove cohabitation through evidence such as shared residence, commingled finances, joint social activities, and testimony from neighbors or acquaintances.
South Carolina includes an anti-circumvention provision in S.C. Code § 20-3-130(B)(6) stating that the court may determine continued cohabitation exists if there is evidence that the supported spouse resides with another person in a romantic relationship for periods of less than 90 days and the two periodically separate to circumvent the requirement. A paying spouse seeking termination based on cohabitation must file a modification action in the family court that issued the original decree.
Death and Remarriage
Alimony terminates automatically upon the death of either the paying or receiving spouse. However, if alimony was secured through a life insurance policy or other mechanism as provided in S.C. Code § 20-3-130(D), payments may continue through the secured asset. Remarriage of the supported spouse terminates periodic, rehabilitative, and reimbursement alimony but does not terminate lump-sum alimony obligations.
Agreeing to Non-Modifiable Alimony
South Carolina allows divorcing spouses to contractually agree to make normally modifiable alimony non-modifiable or vice versa. Under S.C. Code § 20-3-130(C), parties may agree in writing, if properly approved by the court, to make the payment of alimony nonmodifiable and not subject to subsequent modification by the court. This provision gives couples flexibility to structure alimony arrangements that meet their specific needs.
When Non-Modifiable Alimony Makes Sense
A paying spouse may agree to slightly higher alimony payments in exchange for the certainty that amounts will never increase. A receiving spouse may accept lower payments in exchange for guaranteed amounts that cannot be reduced regardless of the paying spouse's future financial success. These agreements trade flexibility for predictability and can benefit either party depending on their circumstances and risk tolerance.
Court Limitations
While divorcing spouses can enter agreements making normally modifiable alimony non-modifiable, the court cannot order this absent their agreement. A judge cannot unilaterally declare periodic alimony to be non-modifiable; only the parties themselves can agree to this arrangement. Any such agreement must be in writing and approved by the court to be enforceable.
Cost of Alimony Modification in South Carolina
The total cost of alimony modification South Carolina parties face depends on whether they hire an attorney and whether the modification is contested. The base filing fee is $150, but total costs can range from $150 for a simple consent modification to $5,000 or more for a contested hearing requiring attorney representation and expert witnesses.
| Cost Component | Amount Range |
|---|---|
| Filing Fee | $150 |
| Process Service (Sheriff) | $50-$75 |
| Process Service (Private) | $75-$125 |
| Motion Fees (each) | $25 |
| Certified Copies | $2-$5 per page |
| Attorney Fees (simple) | $1,500-$3,000 |
| Attorney Fees (contested) | $3,000-$10,000+ |
| Expert Witnesses | $500-$2,000 |
Fee Waiver Options
South Carolina residents who cannot afford filing fees may request a fee waiver using Form SCCA/400 (Motion and Affidavit to Proceed In Forma Pauperis). Low-income filers may qualify if household income falls below 125% of the federal poverty level, which is $19,500 for an individual or approximately $40,000 for a family of four in 2026. The court reviews the application and grants waivers based on demonstrated financial need.
2025-2026 Pending Alimony Legislation
Multiple bills have been introduced in the South Carolina Legislature during the 2025-2026 session that would significantly change alimony laws if passed. Bill 3098, introduced January 14, 2025, proposes limiting alimony to one year of support per three years of marriage. As of May 2026, none of these bills have passed into law, but individuals should monitor legislative developments that could affect their alimony rights or obligations.
The proposed legislation would limit the duration of periodic alimony based on the length of the marriage and impose stricter standards for modification. However, any such changes would apply only to divorces finalized after the effective date of the new law and would not retroactively affect existing alimony orders unless specifically provided in the legislation.
