South Carolina Marriage Age and License Rules Explained
Understand South Carolina’s marriage age limits, consent rules, and license steps before you say “I do.”
South Carolina law sets clear rules about who can get married, at what age, and under what conditions. Understanding these requirements is essential for couples, parents of teens, and anyone planning a ceremony in the state. The rules do more than set a birthday cutoff: they regulate parental consent, proof of age, and when a marriage is legally valid or completely void.
This article breaks down South Carolina’s marriage age laws, explains how marriage licenses work, and highlights key protections designed to prevent child marriage and ensure informed consent.
Core Marriage Age Rules in South Carolina
South Carolina uses a combination of minimum age limits and consent requirements to control who can enter into a valid marriage within the state.
Minimum Legal Age to Marry
Under South Carolina statute, anyone younger than 16 years old is legally incapable of entering into a valid marriage. Any marriage involving a person under 16 is considered void from the outset (void ab initio). This rule applies both to licensed marriages and to common-law marriages (which South Carolina has largely abolished for new unions, but the age rule still matters historically).

For individuals aged 16 and 17, marriage is possible, but only with proper parental or guardian consent and compliance with documentation requirements.
At 18 years of age and older, a person is generally free to marry in South Carolina without anyone else’s permission, provided the usual license and ceremony requirements are satisfied.
| Age | Can Marry? | Consent Needed? | Legal Status |
|---|---|---|---|
| Under 16 | No | Not applicable | Marriage is void ab initio (never legally valid) |
| 16–17 | Yes, in limited circumstances | Parental/guardian consent required | Valid if statutory consent and license requirements are met |
| 18+ | Yes | No parent or guardian consent required | Valid if license and ceremony requirements are satisfied |
Parental Consent Rules for 16- and 17-Year-Olds
Although South Carolina still allows marriage at 16 or 17, the law requires specific, documented consent from the adult who has custody of the minor. This is designed to prevent coerced or secret marriages and to ensure that a responsible adult is involved in the decision.
Who Must Give Consent?
When either applicant is between 16 and 18 and lives with a parent, relative, or guardian, the probate judge or other officer issuing marriage licenses cannot approve the marriage until they receive a sworn statement from that adult.
- Custodial parent: If parents are separated or divorced, the parent with legal custody must provide consent; courts often require evidence of custody such as a separation agreement or divorce decree.
- Legal guardian or relative: If the teen lives with another guardian or relative, that person can provide consent through a sworn affidavit.
The consent must usually take the form of a sworn affidavit signed before the probate judge or other authorized officer. This document becomes part of the official record associated with the marriage license application.
Pregnancy-Related Exception
South Carolina law historically provided an exception where a pregnant minor under 18—and the child’s father—could marry without the father’s parents’ consent, though the young woman’s parent or guardian still had to approve. In situations where she does not have a parent or legal guardian, the Department of Social Services (DSS) may step in to grant permission. This exception is narrow and does not remove the requirement that the minor’s own interests and welfare be assessed by an appropriate adult authority.
Proof of Age and Documentation Requirements
Age is not taken on trust. South Carolina requires different types of documentation depending on the applicant’s age, ensuring that no one can casually misrepresent their age to obtain a marriage license.
Under 18: Birth and Identity Records
Applicants under 18 must provide robust proof of age:
- Certified birth certificate, or
- Hospital or baptismal certificate issued and dated within one year after birth, or a certified copy of such a document.
These documents must show the applicant’s date of birth and are filed in the probate court’s records with the application. Minors also typically need photo identification, such as a state ID card, and their Social Security number.
In rare cases where a birth or baptismal certificate cannot be obtained, a separate sworn affidavit by parents, guardians, or the person with whom the minor resides may be used to establish the applicant’s age, but this is a fallback option and still must satisfy the court.
Ages 18 to 24: Documentary Evidence of Age
For applicants between 18 and 24, South Carolina law still requires documentary evidence that proves age to the satisfaction of the probate judge or licensing officer. Acceptable documents typically include:
- Driver’s license
- Military ID
- Certified copy of birth certificate
- Current passport
The officer will note a brief description of the evidence submitted in the official application record.
Applicants 25 and Older
Once an applicant is 25 or older, many probate courts in South Carolina no longer require formal proof of age; however, they will still require basic identification and Social Security numbers or equivalent documentation. Local court procedures can vary, so couples should check with the county probate court where they plan to apply.
Marriage Licenses: Application, Waiting Period, and Validity
Age and consent are only part of the picture. A marriage in South Carolina requires a properly issued marriage license and a legitimate ceremony performed by an authorized officiant. Failing to follow these steps can result in a marriage that is not recognized by the state.
Where and How to Apply
Marriage licenses are issued by the probate court in each South Carolina county. Couples may apply in any county; the license is typically valid statewide rather than only in the county where it was issued.
- Both partners must appear in person to apply.
- Applicants present the required ID, proof of age, and any parental consent documents (if applicable).
- A filing fee is charged; local courts set the amount and may require cash payment.
Mandatory Waiting Period
South Carolina imposes a 24-hour waiting period between application and issuance of the marriage license. The probate court cannot issue the license sooner, and there are generally no exceptions to this rule. Couples should factor this delay into wedding planning, especially if traveling or working around limited courthouse hours.
Many couples apply several days or weeks in advance to avoid last-minute complications or schedule conflicts.
Validity Duration of the License
County courts may specify how long a marriage license remains valid. In practice, South Carolina marriage licenses are often valid for a period such as six months, giving couples adequate time to hold their ceremony. Once the ceremony is performed and the license is signed by the officiant (and witnesses, if used), the document must be returned to the probate court for recording and issuance of certified marriage certificates.
Who May Perform a Valid Marriage Ceremony?
A marriage license alone does not create a marriage; there must be a ceremony conducted by someone the state recognizes as capable of solemnizing marriages.
South Carolina permits ceremonies to be performed by:
- Members of the clergy
- Probate judges
- Notaries public
Witnesses are not legally required in South Carolina, although some license forms include spaces for witness signatures and couples sometimes choose to use them for symbolic or personal reasons.
Protection Against Child Marriage and Coercion
South Carolina’s age and documentation rules reflect broader concerns about child marriage and coercion. Nationally, most states set a general marriage age of 18, with limited exceptions for minors under specified conditions. South Carolina’s prohibition on marriages involving individuals under 16, combined with its strict consent and proof-of-age requirements for 16- and 17-year-olds, aims to prevent very early marriages and ensure that any minor marriage involves oversight by a responsible adult and the court.
Legislative discussions have continued in recent years about tightening these rules further—such as proposals to limit marriage strictly to adults aged 18 and older—to align South Carolina with states that have fully eliminated marriage for minors. These debates often focus on protecting vulnerable teens from exploitation and improving outcomes related to education, health, and long-term economic stability.
Practical Tips for Couples Planning to Marry in South Carolina
For couples, understanding the legal framework helps avoid delays and legal problems. Here are some practical steps:
- Confirm both partners’ ages and gather appropriate proof (birth certificates, IDs, passports).
- If either partner is 16 or 17, contact the relevant probate court early to confirm current procedures for affidavits and consent forms.
- Schedule a visit to the probate court taking into account the 24-hour waiting period before license issuance.
- Select an authorized officiant (clergy, judge, or notary) who understands South Carolina’s rules about signing and returning the license.
- Plan enough lead time before the ceremony so any documentation gaps or consent issues can be resolved.
Frequently Asked Questions (FAQs)
1. Can someone under 16 ever legally marry in South Carolina?
No. State law explicitly states that persons under 16 are not capable of entering into a valid marriage, and any such marriage is void ab initio, meaning it is treated as though it never existed in law.
2. If we are both 17 and want to marry, what do we need?
Both 17-year-olds must apply for a marriage license at a county probate court. Each must provide proof of age (such as a certified birth certificate) and the custodial parent or legal guardian must submit a sworn affidavit or notarized consent form, typically in person at or before the license issuance.
3. Do we need witnesses at our South Carolina wedding?
No. South Carolina does not require witnesses for a marriage ceremony. The officiant’s signature on the marriage license is sufficient, though some couples choose to have witnesses sign for personal or ceremonial reasons.
4. How long after applying can we get our marriage license?
You must wait at least 24 hours after submitting your application before the probate court can issue your marriage license. There are no exceptions to this statutory waiting period, so plan accordingly.
5. Are South Carolina’s marriage age rules likely to change?
Recent legislative proposals in South Carolina have considered raising the marriage age so that only adults 18 and older could wed, eliminating marriages for minors. While such bills reflect growing concern about child marriage, whether and when they become law depends on legislative action in future sessions.
