You are watching a child you love slip into a situation no one wants. One parent has died, or been removed from the child’s life. The other is gone, unfit, or in no condition to step up. You have been the steady presence — the grandmother, the aunt, the older sibling, the trusted family friend — and now you are wondering whether the law will actually let you take custody.
South Carolina law does allow relatives and other non-parents to petition for custody in exactly this kind of case. The path is narrower than many people expect, and courts start from a strong preference for natural parents. But when both parents truly cannot parent, the door is open for a third party to step in.
The Short Answer
A non-parent can be awarded custody of a child in South Carolina when both natural parents are deceased, unfit, or otherwise unable to care for the child, and the non-parent can show the court that custody with them is in the child’s best interests. Two legal frameworks most often apply: the “de facto custodian” statute and the judicially recognized “psychological parent” doctrine. Each has its own requirements, and the right path depends on your relationship with the child and how long you have been caring for them.
The Starting Point: SC Law Presumes Natural Parents Come First
South Carolina treats a natural parent’s right to raise their child as a constitutionally protected interest. That means a family court cannot simply pick whichever adult seems most stable. Before a non-parent can be awarded custody, the presumption that favors the natural parent has to be overcome — and the non-parent carries the burden of proving why.
In the situation where both parents are deceased, that presumption effectively falls away: there is no parent available to claim it. In cases where one or both parents are living but unfit, the non-parent must present clear evidence of unfitness, abandonment, or other compelling circumstances before the court will consider placing the child elsewhere.
When the Parental Presumption Can Be Overcome
South Carolina courts have recognized several situations in which a non-parent’s claim can prevail over a natural parent’s:
- Both parents are deceased. In this case there is no competing custodial right, and the court’s focus shifts to who can best serve the child’s interests.
- A parent has been legally declared unfit — whether through a DSS proceeding, a criminal matter, or findings in family court.
- A parent has abandoned the child or had their parental rights terminated.
- A parent is living but cannot parent because of incarceration, severe substance abuse, untreated mental illness, or similar incapacity.
- “Compelling circumstances” exist that make placing the child with the natural parent contrary to the child’s best interests, even when the parent is not strictly unfit.
The last category is the most discretionary. Judges look at the full picture: who has been parenting the child day to day, what the child’s emotional bonds are, and what disruption would follow from a change. For a deeper look at how SC courts apply these factors, see our post on third-party custody rights in South Carolina and the Jobst decision.
Two Main Legal Paths for Relatives and Caregivers
1. The de facto custodian statute
South Carolina’s de facto custodian statute (S.C. Code § 63-15-60) allows a person who has been the child’s primary caregiver and financial supporter to stand on more or less equal footing with a parent in a custody action. To qualify, a non-parent generally must show, by clear and convincing evidence, that they have been the child’s primary caregiver and financial supporter for:
- Six months or more, if the child is under three years old, or
- One year or more, if the child is three or older.
Once recognized as a de facto custodian, the non-parent’s evidence is weighed alongside the parents’ — not as an outsider asking a court for extraordinary relief, but as a legally recognized caregiver with standing to seek custody.
2. The psychological parent / compelling circumstances doctrine
Even when someone does not meet the technical time requirements of the de facto custodian statute, South Carolina case law recognizes that a person who has taken on a true parental role can seek custody as a “psychological parent.” The doctrine is built on a four-part test that asks whether the biological parent consented to and fostered the relationship, whether the non-parent lived in the home, whether they performed parental functions to a significant degree, and whether a bonded, dependent parental relationship has formed.
This framework matters most when a grandparent, aunt, uncle, or family friend has been raising the child informally — sometimes for years — without a formal custody order in place.
A Note on Dss Involvement
If the South Carolina Department of Social Services has removed the child from a parent, or is pursuing termination of parental rights, the legal landscape shifts. DSS proceedings follow their own statutory framework, and the department generally prefers kinship placements — which means relatives who step forward early have a real opportunity to become the placement of choice. Our overview of DSS permanency planning hearings in South Carolina explains the timeline DSS runs on. For the companion question of how a parent’s rights can be ended, see our post on termination of parental rights — grounds and procedure. Third-party custody filings and DSS actions can run on parallel tracks, and coordinating the two matters — if DSS is already involved in your family, call us.
What a Family Court Judge Actually Weighs
Whether the case proceeds under the de facto custodian statute or the psychological parent doctrine, the judge ultimately has to decide what is in the child’s best interests. The factors that tend to carry weight include:
- Who has been providing day-to-day care — meals, school, medical appointments, bedtime.
- The strength and length of the child’s bond with the non-parent.
- The stability of the home the non-parent is offering — housing, income, support network.
- The child’s own wishes, depending on age and maturity.
- Whether the non-parent can support the child’s relationships with siblings and extended family.
- Any history of abuse, neglect, or domestic violence.
Practical Steps Before You File
- Start documenting now. Write down when the child came to live with you, who has been paying for what, and which school, doctor, and daycare records list you as the contact.
- Gather proof of the parents’ situation. Death certificates, DSS findings, police reports, criminal records, or medical records that explain why the parents cannot parent.
- Do not assume informal arrangements will protect you. A handshake agreement with a parent — even one that has lasted for years — gives you no legal authority to enroll the child in school, consent to medical care, or stop a parent from taking the child back.
- Talk to a South Carolina family law attorney early. The choice between a de facto custodian action, a psychological parent action, a guardianship, or waiting for DSS to act changes the strategy, the timeline, and what evidence you need.
Talk to a Charleston Family Lawyer Before Things Get Harder
Third-party custody cases are some of the most emotionally charged matters a family court handles. They also reward preparation: the families who succeed tend to be the ones who gather the record, understand the path, and move before an emergency forces a quick decision.

Frequently Asked Questions
Can a grandparent get custody in South Carolina if the parents are still alive?
Yes, in narrow circumstances. If both parents are unfit, have abandoned the child, or if compelling circumstances make parental custody contrary to the child’s best interests, a grandparent can petition for custody. Simply being a better choice than the parents is not enough — the law still starts with a presumption favoring natural parents.
What is a “de facto custodian” in SC?
A de facto custodian is a non-parent who has served as the child’s primary caregiver and financial supporter for a defined period — generally six months for a child under three, or one year for a child three or older. The status is recognized by statute and gives the caregiver legal standing to seek custody.
My sibling died and the other parent is unfit — what do I do first?
Get the child’s basic records in order (school, medical, custody paperwork if any), collect documentation of the surviving parent’s unfitness, and contact a family law attorney quickly. Depending on where the child is currently living, there may be options ranging from an emergency custody filing to a guardianship to a full third-party custody action.
Do I need a lawyer for a third-party custody case?
Third-party custody is one of the most complex areas of SC family law. You are asking a court to overcome a constitutional presumption in favor of a parent, and the rules of evidence are strict. Handling one of these cases without an experienced SC family law attorney is possible, but it is rarely the right call when the child’s future is on the line.
