What Guardianship Costs: the Filing Fee Is the Small Part

Updated August 3, 2026. Quick answer: we are not going to give you a national figure, because we could not verify one. What we can tell you is which costs exist, and that the filing fee — the only number most pages quote — is usually the smallest of them.

What actually drives the cost

Court filing fees, a court-ordered investigation or evaluation, attorney fees for the petitioner, court-appointed counsel or a guardian ad litem for the respondent, a physician’s capacity declaration, and bond premiums. The filing fee is usually the SMALLEST of these.

Read that list again with the fee last. A petition fee in the low hundreds sits alongside two sets of lawyers — yours, and often court-appointed counsel for the person you are petitioning about — plus a physician’s evaluation, an investigator, and a bond premium sized to the estate. That is the real bill, and none of it is published anywhere we could verify.

The figures we could verify

California publishes its filing fees, so those we can state. Read at source on read 2026-08-03:

No national cost range is published. Attorney, investigator, evaluation and bond costs could not be verified from any primary source, and those are the larger drivers.

We would rather say that than repeat a range we cannot stand behind. If you see a confident national figure for what guardianship costs, ask what it is sourced to — the answer is usually nothing. The one part anyone can price is the court fee, and our guardianship cost estimator shows what the court itself charges, state by state, from each state’s own fee statute.

The cost that is easiest to miss

It does not end at appointment. A guardianship of the estate carries ongoing accountings to the court, often prepared by a lawyer or an accountant, for as long as it lasts — which under California’s statute is until death or a court order. What that duty involves.

So the honest comparison is not a document against a one-off court process. It is a document against a court process plus a recurring annual cost for the rest of someone’s life. Which is the argument for signing while you still can.

How to find out what it costs where you are

1. Your state court’s self-help site publishes filing fees, and is the only figure you will get for free.
2. Ask two local attorneys for a flat quote for an uncontested petition. Uncontested is the cheap case.
3. Ask what a contested one costs, because a relative objecting changes the number completely.
4. Ask whether the estate pays — in many cases fees come out of the assets of the person being placed under guardianship.
5. Ask about the bond, which is priced off the estate value and recurs.

Where we have already read that fee schedule. These pages quote each state’s own statute or published court fee schedule, and say so plainly where the state publishes no figure at all — which is most of the bill, everywhere.

Fee waivers exist where income is low, and both California pages we read say so.
