Guardianship for a Disabled Adult in South Carolina: Probate Court Process, Costs, and Alternatives

When your child turns 18 in South Carolina, they become a legal adult with full decision-making authority — regardless of their disability. If they genuinely cannot make or communicate responsible decisions about their health, safety, or finances, guardianship through the county probate court may be the right step. But it is also the most restrictive option available, and South Carolina law requires the court to consider every less restrictive alternative before granting it.

How South Carolina Separates Guardianship and Conservatorship

South Carolina treats these as two distinct legal roles under S.C. Code § 62-5-301 et seq. A guardian handles personal decisions: medical care, residential placement, and day-to-day welfare. A conservator, appointed under § 62-5-401, manages property, finances, and assets. You can petition for one or both, depending on what the young adult actually needs.

This separation matters because many families only need financial oversight while their adult child can still participate in personal decisions with support. Filing for full guardianship when a limited conservatorship would suffice strips rights the court could have preserved.

The Probate Court Filing Process

The petition is filed in the probate court of the county where the young adult lives. Here is the sequence:

1. File the petition. Use Form #530GC for guardianship or Form #540GC for conservatorship, along with the summons (Form #401PC). The filing fee is $150.
2. Obtain the medical examiner report. A licensed physician must complete Form #539GC, documenting the clinical basis for the alleged incapacity. This is not optional — the court will not proceed without it.
3. Background checks. The proposed guardian needs a SLED criminal background check ($25) and a credit report.
4. Court-appointed professionals. The probate court will appoint an independent attorney to represent the young adult (called the Alleged Incapacitated Individual, or A.I.I.) and may appoint a Guardian Ad Litem to make recommendations. Their fees come from the young adult's assets or, if they are indigent, from the petitioner.
5. Hearing. The court evaluates whether incapacity has been proven by clear and convincing evidence and whether less restrictive alternatives are insufficient.
6. Ongoing obligations. Guardians must file annual reports on the person's condition. Conservators must submit detailed annual financial accountings to the court.

Under S.C. Code § 62-5-303(C), you can file the petition up to 180 days before the young adult's 18th birthday, which gives the court time to process the case before legal adulthood arrives.

What Guardianship Actually Costs

The expenses add up faster than most families expect:

• Probate court filing fee: $150
• SLED background check: $25
• Clinical examiner fees: $300–$1,000+, depending on the evaluator
• Court-appointed attorney and GAL fees: Variable, paid from the young adult's assets or by the petitioner
• Private attorney representation: $2,000–$5,000 for an uncontested case; $7,500+ if contested or involving complex conservatorship accountings
• Annual accounting filing: $10 per filing for conservatorship accountings

For a family already managing therapy costs, medical bills, and equipment needs, these expenses are significant — especially when they recur annually.

Why the Court Requires Alternatives First

S.C. Code § 62-5-304(A) explicitly mandates that the probate court "encourage the development of maximum self-reliance and independence." The court must limit any guardianship order to the minimum extent necessary and deny the petition entirely if less restrictive options can meet the young adult's needs.

Those alternatives include Supported Decision-Making agreements, durable powers of attorney (both financial and healthcare), and the Adult Students with Disabilities Educational Rights Consent Act for school-related decisions. Each of these preserves more of the young adult's autonomy and avoids the ongoing costs and court oversight that guardianship requires.

If your family is weighing these options alongside guardianship, the South Carolina Adult Disability Benefits Guide walks through the full decision-making spectrum — from least to most restrictive — with the specific South Carolina forms and filing steps for each path.

When Guardianship Is the Right Call

Not every young adult can safely exercise their rights even with supports in place. If the clinical evidence shows that the person truly cannot understand or communicate decisions about their medical care, safety, or finances — even with a supporter present — then guardianship provides the legal structure to protect them. The key is matching the level of restriction to the actual level of need, which is exactly what the probate court evaluates at the hearing.

Families who do pursue guardianship should start the clinical evaluation and SLED background check at age 17, file the petition when the 180-day pre-birthday window opens, and arrive at the hearing with organized documentation showing both the young adult's limitations and the alternatives that were considered.
