For a will to be valid in South Carolina, the requirements are straightforward: the document must be in writing, signed by the person making it, and signed by at least two witnesses who either watched the signing or heard the testator acknowledge the signature. The person making the will must be at least 18 (or married or emancipated) and of sound mind. Miss any of these, and the document has no legal effect, no matter how clearly it expresses someone’s wishes.
Who Can Make a Will
You must be of sound mind and not a minor. South Carolina defines a minor as someone under 18, but a married or emancipated person under 18 can also make a will.1South Carolina Legislature. South Carolina Code 62-2-501 – Who May Make a Will
Sound mind means understanding the nature and extent of your property, knowing who your natural heirs are, and grasping the effect of signing a will. A diagnosis of dementia or another cognitive condition does not automatically disqualify someone. What matters is whether the person had that understanding at the moment they signed. This is why capacity challenges after death often turn on medical records dated near the signing, testimony from the drafting attorney, and observations from people who saw the testator around that time.
The Three Execution Requirements
Every South Carolina will must satisfy three things: it has to be in writing, it has to be signed by the testator (or by someone else in the testator’s presence and at their direction), and it has to be signed by at least two witnesses who saw the signing or the acknowledgment of the signature.2South Carolina Legislature. South Carolina Code 62-2-502 – Execution
Writing means a physical document. Audio recordings, video recordings, and voice memos do not count. The document does not have to be typed, and it does not have to be prepared by a lawyer, but it does have to exist on paper (or its equivalent) with a signature on it.
The testator’s signature can be made by another person, but only in the testator’s presence and at their direction. This accommodates people who are physically unable to sign but still have full capacity and intent.
Witnesses do not need to read the will or know what it contains. They only need to observe the testator sign, or hear the testator acknowledge a signature that was made earlier. The statute does not explicitly require both witnesses to be present at the same time, but signing everything in a single sitting is the practice that avoids most later disputes about whether execution was proper.
Choosing Witnesses
South Carolina lets a beneficiary serve as a witness, but there is a price. If a will does not have at least two other disinterested witnesses, any gift to the interested witness is void to the extent it exceeds what that witness would have received under intestacy law.3South Carolina Legislature. South Carolina Code 62-2-504 – Subscribing Witnesses Not Incompetent Because of Interest A beneficiary who witnesses the will can lose part of their inheritance. Use witnesses who receive nothing under the document.
Self-Proving Affidavits
A self-proving affidavit is a sworn statement, signed by the testator and at least one witness before a notary or other officer authorized to administer oaths, that verifies the will was properly executed. South Carolina allows this affidavit to be added at the time of signing or at any point afterward.4South Carolina Legislature. South Carolina Code Title 62 – South Carolina Probate Code – Section: 62-2-503
The affidavit is not required for the will to be valid, but its absence causes problems later. Without it, the probate court may require witnesses to appear in person to verify the will. Years after signing, witnesses may have moved, died, or become impossible to locate. A properly notarized self-proving affidavit eliminates that step and carries the same weight as live courtroom testimony. It takes only a few extra minutes at execution.
Formats South Carolina Recognizes and Rejects
The standard format is the attested will: a written document signed by the testator and two witnesses, ideally paired with a self-proving affidavit. This is the format every South Carolina resident should use, and it is the least likely to face a successful challenge.
Two other formats deserve mention because people often assume they work, and in South Carolina they generally do not.
Handwritten (Holographic) Wills
A holographic will is entirely handwritten and signed by the testator, usually without witnesses. South Carolina does not recognize holographic wills created within the state. A holographic will that was validly executed in another state where such wills are legal may be admitted to probate here, because South Carolina’s choice-of-law provision allows a written will to be valid if its execution complied with the law of the place where it was executed or the place where the testator was domiciled at the time of execution or death.5South Carolina Legislature. South Carolina Code Title 62 – South Carolina Probate Code – Section: 62-2-505 Cross-border recognition is fact-specific and uncertain. A South Carolina resident who wants their wishes honored should execute a formal attested will.
Oral Wills
South Carolina does not recognize oral wills under any circumstances. A spoken declaration, even one made before multiple witnesses on a deathbed, has no legal effect. If a person dies without a valid written will, property passes under intestacy law regardless of what they said out loud.6South Carolina Legislature. South Carolina Code 62-2-101 – Intestate Estate
Changing or Revoking a Will
A valid will can be revoked in two ways. The first is executing a new will that expressly revokes the old one or contains provisions inconsistent with it. The second is physically destroying the original with the intent to revoke, meaning burning, tearing, canceling, or obliterating the document. The destruction can be done by the testator personally, or by someone else acting in the testator’s presence and at their direction.7South Carolina Legislature. South Carolina Code 62-2-506 – Revocation by Writing or by Act If a will is found damaged after the testator’s death, courts generally presume revocation was intended, though evidence can overcome that presumption.
Amendments are made through a codicil, and a codicil must meet the same execution requirements as the will: written, signed by the testator, and signed by two witnesses. Codicils are convenient for small changes, but stacking several over the years tends to create contradictions. When provisions genuinely conflict, the most recently executed valid document controls. For anything substantial, drafting a new will with an express revocation clause is cleaner than layering codicils.
What Divorce Does Automatically
Once a divorce, annulment, or similar proceeding becomes final, South Carolina law treats a former spouse as if they had predeceased the testator. Provisions in the will benefiting the ex-spouse are automatically revoked, and the same treatment reaches a range of instruments executed before the divorce, including revocable trust provisions, life insurance beneficiary designations, retirement account designations, and powers of attorney naming the former spouse.8South Carolina Legislature. South Carolina Code Title 62 – South Carolina Probate Code – Section: 62-2-507 Revoked provisions are revived if the couple remarries. No other change of circumstances triggers automatic revocation.
What a Valid Will Cannot Do
Meeting the requirements above produces a valid will, but a valid will is not unlimited. Two protections in the probate code and one category of assets sit outside the will’s reach.
Elective Share for a Surviving Spouse
A surviving spouse of a South Carolina resident who dies with a will can reject what the will provides and claim one-third of the decedent’s probate estate.9South Carolina Legislature. South Carolina Code Title 62 – South Carolina Probate Code – Section: 62-2-201 This is the elective share, and it exists regardless of what the will says. A will that leaves a surviving spouse nothing can still be partially overridden. If the deceased was domiciled elsewhere, the surviving spouse’s rights against South Carolina property are governed by the law of the decedent’s home state.
Children Born After the Will
If a child is born or adopted after a will is executed and the will makes no provision for that child, the child is entitled to an intestate share of the estate. Three exceptions apply: the will’s language shows the omission was intentional, the testator had other children at the time and left substantially everything to the surviving spouse, or the testator provided for the child outside the will and intended those transfers to serve as the child’s inheritance.10South Carolina Legislature. South Carolina Code Title 62 – South Carolina Probate Code – Section: 62-2-302 Anyone whose family grows after signing a will should review the document.
Assets That Do Not Pass Through the Will
A will controls only the probate estate. Retirement accounts like 401(k)s and IRAs with designated beneficiaries, life insurance policies with named beneficiaries, pay-on-death bank accounts, transfer-on-death brokerage accounts, and property held in joint tenancy with right of survivorship all transfer directly to the named recipient or surviving owner. The beneficiary designation on file with the account provider controls, and the will cannot override it.
This is where people routinely trip themselves up: they update the will after a divorce but never change the beneficiary on an old life insurance policy or 401(k), and the ex-spouse collects. South Carolina’s automatic revocation on divorce reaches many of these designations, but the safer practice is to confirm each one directly with the account provider whenever life circumstances change.
South Carolina does not currently have a transfer-on-death deed statute for real property, so a house or land cannot be passed to a beneficiary at death through a recorded TOD deed the way some other states allow. Legislation to create that mechanism was introduced in the 2025–2026 session but had not been enacted at the time of this writing. For now, real property in South Carolina generally must pass through probate or be held in a trust to avoid court proceedings.
