Georgia Guardianship Capacity Standard Under O.C.G.A. § 29-4-1

The Standard Is Functional, Not Diagnostic

Georgia's guardianship law under O.C.G.A. § 29-4-1 uses a functional capacity standard. A court cannot grant a guardianship based on a diagnosis alone — not autism, not Down syndrome, not traumatic brain injury, not any clinical label. The question is whether the individual can receive and evaluate information, formulate a decision, and communicate that decision in the specific domains where the petitioner is seeking authority.

This distinction matters because capacity is domain-specific. A person might lack the capacity to manage complex financial investments while fully retaining the capacity to make healthcare decisions, choose where to live, or participate meaningfully in their IEP. Georgia law requires the court to tailor any guardianship order to the specific domains where incapacity is demonstrated — not issue a blanket removal of rights.

What HB 36 Changed

House Bill 36, effective July 1, 2025, fundamentally strengthened the capacity standard in two ways.

First, it explicitly prohibited the presumption that a developmental disability diagnosis alone warrants a guardian. Before HB 36, some probate courts treated diagnostic labels as near-sufficient evidence of incapacity. The new law requires petitioners to demonstrate actual functional limitations through a comprehensive evaluation — not just present a medical record.

Second, HB 36 expanded the categories of licensed clinicians authorized to perform the mandatory evaluation and sign the pre-filing affidavit. The authorized list now includes licensed physicians, psychologists, clinical social workers, physician assistants, psychiatric nurse practitioners, clinical nurse specialists, licensed professional counselors, and licensed marriage and family therapists. This expansion directly addresses the evaluator shortage in rural Georgia counties, where families previously had to travel to metro Atlanta to find a qualified professional.

What the Evaluation Actually Measures

The court-appointed evaluator — who must be independent from the clinician who signed the pre-filing affidavit — is required to assess:

• Functional abilities: Can the individual understand information presented to them? Can they weigh options and consequences? Can they formulate and express a choice?
• Medical and school records: What does the individual's documented history show about their functioning over time?
• Existing support systems: Is the individual already receiving effective support from family, service providers, or community organizations?
• Cultural and linguistic factors: Are apparent limitations actually capacity deficits, or are they communication barriers, cultural differences, or language issues?

The evaluator must file a sworn written report within 7 days of the evaluation. Both the petitioner and the proposed ward's court-appointed attorney can challenge the evaluator's methodology and credentials at the hearing.

Clear and Convincing Evidence

The petitioner bears the burden of proving incapacity by clear and convincing evidence — a standard higher than the "preponderance of the evidence" used in most civil cases. This means the evidence must produce a firm belief or conviction in the judge's mind that the individual truly lacks functional capacity in the specific domains at issue.

Vague concerns about an adult child "making bad decisions" or "being too trusting" don't meet this standard. The petitioner must present specific, documented evidence that the individual cannot receive, process, or communicate decisions in particular areas of their life.

The Less Restrictive Alternatives Requirement

Even when incapacity is established, O.C.G.A. § 29-4-1(f) requires the court to determine that no less restrictive alternative — supported decision-making, powers of attorney, healthcare directives, representative payee arrangements — would adequately protect the individual. A guardianship is the legal last resort, not the default path.

Understanding Georgia's capacity standard helps families prepare better petitions when guardianship is truly necessary, and recognize when alternative planning tools would serve their adult child better while preserving more autonomy.
