Guardianship in New Hampshire: Types, Duties, and Costs

Guardianship in New Hampshire is a court-ordered arrangement that gives one person legal authority to make decisions for a minor whose parents cannot care for them or for an adult who can no longer manage their own affairs. The process runs through the Probate Division of the Circuit Court, and the bar is high: for an incapacitated adult, the petitioner must prove the need beyond a reasonable doubt, the same standard used in criminal cases.¹ Because guardianship removes fundamental rights, a judge will not grant it when a less restrictive option can meet the person’s needs. Minors are covered by RSA 463; incapacitated adults by RSA 464-A.

Types of Guardianship

A New Hampshire court can appoint a guardian of the person (healthcare, housing, daily decisions), a guardian of the estate (finances and property), or both. The authority is tailored to what the individual actually cannot do.

Guardianship of a Minor

When a child’s parents are unable or unwilling to provide care — because of substance abuse, incarceration, abandonment, or serious illness — the court can appoint a guardian under RSA 463. The guardian becomes legally responsible for the child’s education, healthcare, and living arrangements.² Guardianship is not adoption. Parental rights remain intact, parents can petition to regain custody if their circumstances improve, and the arrangement ends automatically at age 18 unless the court orders otherwise.

Guardianship of an Incapacitated Adult

RSA 464-A covers adults who cannot make informed decisions due to conditions such as dementia, traumatic brain injury, or severe mental illness. Incapacity is a legal finding, not a medical label. The statute measures it by functional limitations in managing one’s affairs, so a diagnosis by itself is never enough.³ The petitioner must show that the person cannot handle specific tasks like paying bills, making medical decisions, or arranging safe housing.

The respondent has the right to attend the hearing, testify, and be represented by an attorney, and can contest the petition. If the court appoints a guardian, that guardian must file annual reports, and the court keeps ongoing oversight with authority to modify or terminate the arrangement.⁴

Limited Guardianship

When a person can still handle some decisions but not others, the court can impose a limited guardianship. The order spells out exactly which powers pass to the guardian and which stay with the individual. Someone might, for example, retain control of their finances while the guardian handles medical decisions. Any right not explicitly transferred remains with the individual. Courts prefer this outcome because it preserves autonomy.⁴

Temporary Guardianship

In an emergency, RSA 464-A:12 allows the court to appoint a temporary guardian for an incapacitated adult on shortened notice. The petition must explain why the standard process would be too slow to prevent serious harm, and the appointment is limited to specific duties such as protecting particular property or preventing immediate physical or mental harm. A temporary guardianship cannot last longer than 60 days, and the temporary guardian must file a full guardianship petition within that window to keep serving.⁵

Alternatives You Have to Consider First

Before granting a guardianship petition, a New Hampshire judge is required to consider whether a less restrictive alternative can meet the person’s needs. If one can, the petition will be denied. It’s worth working through the alternatives before filing anything.

Durable power of attorney. A person who still has legal capacity can sign a durable power of attorney naming someone to make financial or healthcare decisions on their behalf. The document survives later incapacity. If a valid one is already in place and the agent is acting appropriately, courts often find that guardianship is unnecessary.
Supported decision-making agreement. Since January 1, 2022, New Hampshire formally recognizes supported decision-making. A person with a disability chooses trusted supporters who help them understand information and make their own decisions, rather than having a guardian decide for them.⁶
Representative payee. If the concern is only managing Social Security or similar benefits, the Social Security Administration can appoint a representative payee without any court proceeding.
Community supports. Visiting nurses, home health aides, adult day care, and residential care facilities are also listed in New Hampshire law as arrangements that may eliminate the need for guardianship.⁶

These options only work while the person has enough capacity to participate, or while a document like a power of attorney is still effective. When those conditions no longer hold, guardianship may be the only remaining option.

Who Can Serve as Guardian

Under RSA 464-A:10, any person who agrees to serve may be appointed. Family members and volunteer guardians are named first. Professional guardians are also eligible; they must be certified through the Center for Guardianship Certification and must follow the National Guardianship Association’s standards of practice and code of ethics.⁷⁸ If no suitable individual is available, the court may turn to a public guardianship program.

The court evaluates each candidate’s fitness, including financial stability, criminal history, and past conduct. A background check is standard when the guardian will manage assets. An institution or agency providing care to the individual generally cannot be appointed. If no one else is available, an employee of the facility may serve, but only if that employee does not directly care for the ward and the court makes a specific finding of no substantial conflict of interest.⁷

Anyone with legal capacity can also nominate their own future guardian in a written instrument executed with the same formalities as a deed. The nomination can name substitutes and exclude specific people, and it survives the signer’s later disability. It applies to both regular and temporary guardianships.⁷ Planning ahead this way can prevent disputes when a progressive condition is likely. For minors, RSA 463:5 lets a parent nominate a guardian by will, by petition, or by written consent to another person’s petition. A minor 14 or older can petition for their own guardian.⁹

How to Petition the Court

File the petition with the Probate Division of the Circuit Court. It must explain why guardianship is necessary, identify the proposed guardian, and specify the powers being requested.¹⁰ For an incapacitated adult, the petition must also address whether the proposed ward has a durable power of attorney or living will, the type and duration of guardianship sought, and the names of the proposed ward’s relatives. The filing fee is $260, plus certified mail costs for each person who must receive the order of notice.¹¹

For an adult petition, a physician’s affidavit is required under RSA 464-A:8, assessing the person’s functional limitations and decision-making ability.¹² The affidavit matters but doesn’t decide the case. Because incapacity is a legal question, the judge weighs the medical evidence alongside testimony from family, social workers, and others who see the person day to day.

Once the petition is filed, the court schedules a hearing and orders notice to all interested parties, including the person subject to the petition, their immediate relatives, and any relevant agencies. The respondent may attend, testify, and have an attorney; if they cannot afford one, the court may appoint counsel. The court may also appoint a guardian ad litem to conduct an independent investigation and report on whether the proposed arrangement serves the respondent’s best interests. Contested cases often turn on the GAL’s findings and on competing medical testimony.

At the hearing, the petitioner must prove beyond a reasonable doubt that the person is incapacitated and needs a guardian, and that no less restrictive alternative will do.¹ If the court is satisfied, it issues a decree setting out the guardian’s responsibilities and limitations. The appointed guardian must file an acceptance and may be required to post a surety bond if they will manage financial assets. If the evidence shows the respondent retains some decision-making ability, the court may grant a limited guardianship instead of a full one.

What Guardians Have to Do

A guardian is accountable to the court. Acting outside the scope of the order, or failing to report, can lead to removal and personal liability.

Guardian of the Person

A guardian of the person handles healthcare, living arrangements, education, and daily needs. Under RSA 464-A:25, the guardian must provide for the ward’s care, comfort, and maintenance, arrange training, education, or rehabilitation where appropriate, and take responsibility for clothing and personal effects.⁴

Medical authority is not automatic. A guardian can consent to treatment only if the court specifically authorized that power, and the court reviews that authority in each annual report. Certain procedures need their own separate court order: psychosurgery, electroconvulsive therapy, sterilization, and experimental treatment. If the ward previously signed a valid living will, the guardian must honor its terms unless the court orders otherwise after a hearing. Placement in a state institution or other residential facility also requires prior court approval, with a finding beyond a reasonable doubt that the placement is in the ward’s best interest and the least restrictive option.⁴

Guardian of the Estate

A guardian of the estate manages the ward’s finances and property with the same prudence, discretion, and care a reasonable person would apply to their own affairs, under RSA 464-A:26.¹³ After appointment, the guardian must file an inventory of the ward’s assets following the procedures used for estates of deceased persons under RSA 554.¹⁴ After that, the guardian files annual financial accountings unless the court determines annual reporting is unnecessary. Mismanagement or financial exploitation can result in removal and personal legal consequences.

Annual Reports

Every guardian files an annual report. For a guardian of the person, that covers the ward’s living situation, health, and general well-being. For a guardian of the estate, it’s a full financial accounting showing income, expenses, and assets. The court uses these reports to decide whether the guardian is doing the job and whether the guardianship should continue.

What It Costs

The $260 filing fee is only the start.¹¹ Attorney fees are the largest expense for most families, and a contested case pushes costs significantly higher because of the added hearings, discovery, and expert testimony. A guardian ad litem, if appointed, bills separately, typically by the hour. Medical evaluations for adult incapacity add more. When the court requires a surety bond for a guardian of the estate, the annual premium depends on the estate’s value and the guardian’s credit. Because annual accountings and bond renewals recur, these costs continue for the life of the guardianship.

Ending or Changing a Guardianship

Guardianship of a minor ends automatically at age 18. Adult guardianship ends by court order, by the ward’s death, or when the court finds the ward is no longer incapacitated or that other arrangements can meet their needs.¹⁵

The ward or any interested person can move to terminate, arguing that capacity has returned or that an alternative now works. One catch: the original incapacity order can impose a waiting period of up to one year before such a motion can be filed without the court’s special permission.¹⁵ The court reviews medical evidence and holds a hearing before terminating.

If the guardian dies, becomes unable to serve, or is found unfit, the court can appoint a successor. That petition doesn’t require re-proving incapacity. It explains why a new guardian is needed, and the court evaluates whether the proposed replacement is suitable. The ward and interested parties receive notice and can object. Unless the court modifies the order, the successor takes on the same powers and duties as the original guardian.
