Guardianship vs Supported Decision-Making in New Jersey: Options, Costs, and the Pre-Filing Law
On your child's 18th birthday, New Jersey law treats them as a legal adult. The parent-child relationship no longer grants automatic authority to view medical records, make healthcare decisions, or participate in IEP meetings if a provider or district objects. Every family needs a legal decision-making framework in place before that day — and the question is which one fits your situation.
The Options: Least Restrictive to Most
New Jersey courts and the Division of Developmental Disabilities both operate under a preference for the least restrictive alternative. Before pursuing guardianship, families are expected to consider whether a less invasive option meets the individual's needs.
Supported Decision-Making Agreements
Supported Decision-Making (SDM) is a process where the adult makes their own decisions with help from a chosen circle of supporters — family members, friends, professionals. The supporters explain options, help gather information, and assist with communication, but the individual retains legal decision-making authority.
New Jersey has no formal statute governing SDM agreements. However, the Division of Developmental Disabilities formally recognizes written SDM agreements in practice. Families use standard model templates to establish structured support circles. The American Bar Association reinforced this approach in February 2026, adopting Resolution 100 — which amends Model Rule 1.14 to explicitly name SDM as an accommodation attorneys must explore before pursuing guardianship.
Cost: Minimal. An SDM agreement can be drafted without an attorney, though legal review is advisable. No court filing required.
Limitation: SDM works when the individual has some capacity to participate in decisions, even with support. Some financial institutions and healthcare providers may not honor an SDM agreement because New Jersey lacks a formal statute — though DDD acceptance helps in the developmental services context.
Powers of Attorney and Advance Directives
If the young adult has the cognitive capacity to understand that they are delegating authority, they can sign a Durable Power of Attorney (for financial matters) or an Advance Directive for Healthcare. These documents are private, voluntary, do not require court involvement, can be revoked at any time, and cost significantly less than guardianship.
Cost: Attorney fees vary by the documents and their complexity, but are generally less than a court guardianship.
Limitation: The individual must have sufficient capacity to understand and execute the documents. If capacity is in question, a provider or institution may challenge the document's validity.
Limited Guardianship
The court grants the guardian authority over specific areas — medical decisions, financial management, residential choices — while the individual retains rights in other areas (voting, marrying, certain vocational decisions). This is the middle ground between full autonomy and plenary guardianship.
Plenary (General) Guardianship
Transfers all legal decision-making rights to the guardian. The individual loses the right to make their own medical, financial, residential, and personal decisions. This is the most restrictive option and is appropriate only when the individual's safety is genuinely at risk without it.
The Private Guardianship Process
Filing a guardianship petition in New Jersey requires:
- Verified Complaint filed with the Superior Court, Chancery Division, Probate Part, in the county of residence
- Two medical certifications from licensed professionals who have examined the individual within 30 days of filing
- $200 filing fee
- The court appoints an independent attorney to represent the individual and schedules a hearing
Total cost for a private guardianship varies; it includes attorney fees, medical evaluations, and the $200 court filing fee. Complex or contested cases can run higher.
The BGS Public Process
If the young adult is eligible for DDD services, the family can request a public guardianship process through the Bureau of Guardianship Services (BGS). BGS petitions for guardianship of the person at no legal cost to the family. This process requires only one medical exam within six months of filing, plus an administrative affidavit from DDD.
BGS handles guardianship of the person only — not property. If the young adult owns significant assets, the family must hire a private attorney for guardianship of the estate.

The Six-Month Pre-Filing Law
P.L. 2025, c. 129 (Senate Bill S2332), signed in late December 2025, allows parents or relative caregivers of individuals with autism or another developmental disability to file a guardianship complaint six months before the individual turns 18.
This eliminated the gap that previously existed: families had to wait until the 18th birthday to file, then spend months navigating court proceedings while their adult child had no legal decision-making framework in place. Under the new law, a family can file at age 17.5 and potentially have guardianship established by the time the birthday arrives.
