Guardianship Cost Calculator

June 30, 2026 • By the Investor Sam Editorial Team • Reviewed by Berly Sam Varghese, Editor
Establishing legal guardianship for a minor or an incapacitated adult is a court process with both up-front and ongoing costs. You pay to petition the court, for an attorney to guide the case, and often for a medical or capacity evaluation. Then, in many states, a guardian must file an annual accounting for years afterward. This calculator separates the one-time setup from the recurring cost so you can see the true lifetime price of a guardianship.

Example: Court petition filing fee: 400 $ · Attorney fee (setup): 3500 $ · Medical / capacity evaluation: 800 $ · Annual accounting / court cost: 600 $ · Expected years of guardianship: 10 years

Total lifetime cost$10,700
One-time setup cost$4,700
Ongoing accounting cost$6,000

Worked example

Setting up a guardianship with a $400 filing fee, a $3,500 attorney fee, and an $800 capacity evaluation costs about $4,700 up front. If the court then requires a $600 annual accounting for ten years, that adds $6,000, for a lifetime total of roughly $10,700. The recurring cost is easy to overlook but can rival the setup over a long guardianship, which is why some families explore less costly alternatives like a power of attorney or a supported decision-making arrangement first.

Frequently asked questions

Is guardianship expensive?

The setup alone can run several thousand dollars once attorney fees, court filing, and an evaluation are added, and courts often require ongoing annual reporting that adds cost for years. Contested guardianships cost far more. Seeing the lifetime figure helps families weigh the commitment realistically.

Are there cheaper alternatives to guardianship?

Sometimes. A durable power of attorney, a healthcare proxy, a representative payee for benefits, or a supported decision-making agreement can meet the need without a full court guardianship, and courts increasingly prefer these less-restrictive options when they are workable.

Why is there an annual cost?

A guardian typically owes the court a periodic accounting of how the protected person's money was managed and how they are doing, sometimes prepared with an attorney or accountant. This ongoing duty protects the vulnerable person but adds recurring cost that this tool projects across the expected years.

Who pays for the guardianship?

Costs are often paid from the protected person's own estate if they have assets, or by the petitioning family member otherwise. Some courts waive or reduce fees for low income. Knowing the total helps determine which source can realistically cover it.
