Turning 18 ends a parent’s automatic legal authority to make medical, financial, and educational decisions on behalf of a child, regardless of diagnosis or continued need for support.
New Jersey does not extend that authority forward.
It has to be established through a court proceeding, and until a judge signs that order, hospitals, schools, and government agencies are not required to treat a parent as anything more than family.
A New Jersey special needs guardianship restores that authority, though the right path depends on whether a child is eligible for services through the Division of Developmental Disabilities or is incapacitated for another reason.
Our senior partner has practiced in New Jersey’s family and estate courts since 1989, and we handle both guardianship paths for families in Monmouth and Middlesex County.

New Jersey guardianship law separates cases into two categories based on why a person needs a guardian.
The category determines which certifications and forms the court requires, and filing under the wrong one can add months to the process. We can confirm which path applies before any paperwork is filed.
A judge can grant a general guardianship, which covers all major decisions, or a limited guardianship, which covers only the areas where a person cannot safely act independently.
New Jersey courts favor the limited approach whenever a person retains some capacity to manage part of their own affairs.
Depending on what a family member can manage, a guardianship can cover:
We evaluate what a client can already do before asking the court for authority beyond that.
A hospital can decline to discuss an adult child’s diagnosis or treatment with a parent who has no legal authority to receive that information.
A school or day program is not required to keep speaking with a parent once a student turns 18.
The Social Security Administration and Medicaid can require the individual, not the parent, to manage their own paperwork, regardless of whether that person can read or understand it.
None of this reflects a judgment about a parent’s role. It reflects a legal rule, since authority does not carry forward automatically, and every institution that touches an adult child’s life has to follow that rule until a court says otherwise.
Under New Jersey Rule 4:86, the court appoints an attorney to represent the person alleged to need a guardian, separate from the attorney representing the family. The complaint must include certifications from two physicians, or one physician and one licensed psychologist, each based on an examination completed within 30 days of filing.
A guardian ad litem may also be appointed if the court believes the person’s interests need additional review.
We can prepare that documentation with the medical providers already involved in a client’s care, which is usually faster than starting with providers who are unfamiliar with the case.

We file guardianship petitions with the Superior Court, Chancery Division, Probate Part, through the county Surrogate’s office.
In Monmouth County, filings go through the Surrogate’s Court at the Hall of Records in Freehold. In Middlesex County, filings go through the Surrogate’s Office on Bayard Street in New Brunswick.
Monmouth and Middlesex County each have their own filing requirements, from the certifications the Surrogate’s office expects to how a petition gets scheduled for a hearing, and a filing that does not match those requirements can be delayed or sent back.
Our team can prepare the verified complaint, arrange the required physician and psychologist certifications, and file directly with the Surrogate’s office in the county where the person needing a guardian resides.
Not automatically. Guardianship takes effect only once a New Jersey court reviews the medical evidence and signs a judgment of incapacity, in whole or in part. Most families file the petition a few months before the 18th birthday so the judgment is in place before the birthday, not after.
Often, yes. New Jersey courts grant only the authority a person needs. If someone can handle certain decisions independently, such as choosing their own friends or making small purchases, the judgment can preserve those rights while granting authority over the rest.
A guardianship petition is generally filed in the county where the person needing a guardian resides. If that is outside Monmouth or Middlesex County, we can still discuss the situation and, where appropriate, refer the filing to co-counsel in the correct county.
Generally, yes, unless the plaintiff and the court-appointed attorney certify that the person cannot appear because of a physical or mental incapacity. When an appearance is not practical, the court can rely on the certifications and the appointed attorney’s report instead.
Filing fees, medical certifications, and attorney’s fees are the primary costs, and in most cases the incapacitated person’s own estate covers them if assets exist. If there are no assets, the person filing the petition typically covers the costs directly. We can provide a cost estimate before any filing begins.
A power of attorney or healthcare proxy is only valid if the person signing it had the legal capacity to understand the document at the time. If a young adult already has that capacity before turning 18, these documents may cover some decisions without a full guardianship. We review what a client can already sign for before assuming guardianship is the only option.
Yes. A guardian, an interested party, or the individual under guardianship can ask the court to modify or terminate the guardianship if circumstances change, supported by a professional’s certification that capacity has improved. Courts take these requests seriously because the standard has always been the least restrictive option that keeps the person safe.
Every family’s situation is different. Contact Weisberg & Klauber, LLC, and we can review your specific circumstances directly.
Filing under the wrong guardianship category, missing a medical certification, or waiting too long after your child turns 18 can add months of unnecessary delay.
