Iowa Probate Bond
Short answer: every Iowa fiduciary is bonded by default under Iowa Code § 633.169, and unlike most states, the dollar figure isn’t left to a judge’s discretion. § 633.170(1) hands the clerk of the district court a fixed formula — the estate’s personal property value, plus its estimated gross annual income during administration — and the clerk applies it without a hearing. You can waive it three ways: the will can say so (§ 633.172), every distributee can agree in writing (§ 633.173), or the court can exempt you for good cause (§ 633.175). Do the math below before you assume you need one.
Iowa Code § 633.170(1): the exact penal-sum formula
Most states leave the bond amount to a judge’s judgment call. Iowa spells it out in the statute itself: “the court or the clerk shall fix the penalty of the bond in an amount equal to the value of the personal property of the estate, plus the estimated gross annual income of the estate during the period of administration.” Two inputs, added together — that’s the whole formula.
Iowa probate bond formula (Iowa Code § 633.170(1))
Iowa Code § 633.170(1). The clerk of the district court applies this formula automatically under § 633.170(2) unless a will waiver, distributee waiver, or court exemption applies.
Because the formula is fixed, you can plug in your own estate’s numbers before you ever talk to an underwriter. A $500,000 estate in mostly stocks and a paid-off house, with no rental income expected, bonds at roughly $500,000 — the income component adds nothing if there isn’t any. A smaller $150,000 estate that includes a rental duplex generating $14,000 a year bonds at $164,000 — the income line can matter more than the estate’s size once real property is producing rent.
The clerk sets it, not a judge — and can’t change it later
Iowa Code § 633.170(2) is explicit about who applies the formula: “Unless a bond is waived by will... or by other instrument creating the estate, or in accordance with section 633.173, or by prior order of court, the clerk shall fix the bond in the amount provided by subsection 1.” No hearing, no judicial sign-off on the number itself — the clerk runs the arithmetic the moment letters are ready to issue.
The same sentence carries an unusual restriction: “The clerk shall not thereafter increase or decrease a bond.” Once the clerk’s formula produces a number, that figure is locked from the clerk’s side — if the estate’s value changes materially during administration, a fiduciary or interested party has to go to the court, not the clerk, to get the bond revisited. Before any bond takes effect at all, § 633.171 requires the clerk to separately examine and approve the surety itself; a bond that isn’t approved sends the fiduciary back to secure a new one on whatever timeline the court or clerk sets.
Practically, this means Iowa fiduciaries rarely wait on a bond hearing the way they would in a judge-discretion state. Give us the personal property value and expected annual income, and we can usually quote the exact clerk-set figure before you file.
Four ways an Iowa fiduciary’s bond question gets resolved
The clerk’s formula is the default outcome — but three separate statutes can take you out of it, each with its own condition.
Iowa probate bond status by path
Governed by Iowa Code §§ 633.170, 633.172, 633.173, and 633.175
| Fact pattern | Bond outcome | Governing statute |
|---|---|---|
| No waiver on file | Clerk fixes bond automatically at personal property + est. annual income | § 633.170 |
| Will directs or expresses that no bond be required | Waived for all purposes, unless court later finds good cause to require one | § 633.172 |
| All distributees waive bond in writing | Waived if court finds creditors won’t be prejudiced | § 633.173 |
| No will waiver, no distributee waiver | Court may still exempt for good cause shown, absent prejudice to creditors | § 633.175 |
A will waiver (§ 633.172) and a distributee waiver (§ 633.173) both remain subject to court override for good cause; a court exemption under § 633.175 requires a finding that creditors and distributees won't be prejudiced.
Iowa Code § 633.170 in the statute’s own words
Official Iowa Requirements
"1. How determined. Except as herein otherwise provided, the court or the clerk shall fix the penalty of the bond in an amount equal to the value of the personal property of the estate, plus the estimated gross annual income of the estate during the period of administration. 2. Bonds fixed by clerk. Unless a bond is waived by will under the authority of section 633.172, or by other instrument creating the estate, or in accordance with section 633.173, or by prior order of court, the clerk shall fix the bond in the amount provided by subsection 1 of this section. The clerk shall not thereafter increase or decrease a bond."Iowa Legislature, Legislative Services Agency • Iowa Code § 633.170

Guardians and conservators aren’t bonded the same way
Iowa Code § 633.174 draws a line most states blur: a guardian who isn’t also the conservator of the same person’s property — meaning they make personal-care decisions but don’t handle money — is not required to post bond unless the court finds good cause to order one. A conservator, who does manage the protected person’s property, gets no such default exemption: every conservator must file a bond with sufficient surety, except as § 633.175 separately allows.
That exception is narrower for conservators than for any other fiduciary on this page. § 633.175(2) bars the court from waiving a conservator’s bond at all — unless the conservator is a financial institution with Iowa trust powers, or a court-approved plan for an alternative form of asset protection is on file. A will’s bond waiver or a distributee’s written consent, which can excuse an executor or administrator, doesn’t reach a conservator’s bond the same way.
Premium math once the clerk sets your figure
Premium is a percentage of whatever number the § 633.170 formula produces, priced the way carriers price fiduciary bonds nationally: roughly 0.5% to 1.5% of the bond amount per year, based mostly on the fiduciary’s personal credit rather than the estate’s complexity.
Worked example
An Iowa estate has $319,500 in personal property plus estimated annual income — the clerk fixes the bond at $319,500 under § 633.170. At a 0.5%–1.5% annual rate, expect a premium of roughly $1,600 to $4,800 per year, with most applicants on reasonable personal credit landing toward the lower end.

What Iowa fiduciaries ask about the probate bond
How does Iowa calculate the probate bond amount?
By formula, not discretion. Iowa Code § 633.170(1) fixes the penalty of the bond at "an amount equal to the value of the personal property of the estate, plus the estimated gross annual income of the estate during the period of administration." Add up what the estate’s personal property is worth, add what it’s expected to earn in rent, interest, or dividends over the coming year, and that sum is the bond. There’s no multiplier to apply on top of it and no separate real-property component — just those two figures added together.
Does an Iowa judge set my probate bond, or does someone else?
In most filings, neither — it’s the clerk of the district court, acting without a hearing. Iowa Code § 633.170(2) says that "unless a bond is waived by will... or by other instrument creating the estate, or in accordance with section 633.173, or by prior order of court, the clerk shall fix the bond in the amount provided by subsection 1," and adds a rule almost no other state’s formula includes: "the clerk shall not thereafter increase or decrease a bond." Once the clerk applies the formula, that figure is locked unless a court order changes it — the clerk doesn’t get a second look. § 633.171 still requires the clerk to examine and approve the surety bond itself before it’s effective, and if the clerk rejects an offered bond, the fiduciary has to secure a new one on the court’s or clerk’s timeline.
Can I avoid an Iowa probate bond if I’m named executor in the will?
Yes, if the will actually says so. Iowa Code § 633.172(1) treats any language in the will directing or expressing "the desire that no bond shall be required" as "a waiver of the posting of a bond by the fiduciary for all purposes." Once that waiver is in the will, no bond is required unless the court finds good cause to order one anyway — and even after granting the waiver initially, the court can reverse course "at any subsequent time" if good cause later appears. § 633.172(2) also exempts bank and trust companies from bond entirely unless the will or a court order says otherwise, regardless of what the will does or doesn’t say about individual fiduciaries.
The will is silent on bond — can the heirs just agree I don’t need one?
Yes, but it has to be unanimous, in writing, and the court has to sign off. Iowa Code § 633.173 waives the bond "if the distributees, in writing waive the statutory requirement that a bond shall be filed... and the court finds that the interests of the creditors will not thereby be prejudiced." Every distributee has to consent — one holdout keeps the clerk’s § 633.170 formula in force — and the court independently checks that creditors aren’t exposed before approving it. Separately, § 633.175 lets the court exempt any fiduciary from bond "for good cause shown" even without a distributee waiver, again only if creditors and distributees won’t be prejudiced.
Are Iowa guardians bonded the same way as conservators?
No — Iowa Code § 633.174 splits them cleanly by what they control. A guardian who isn’t also the conservator of the same person’s property — meaning they handle personal care decisions, not money — is not required to post bond "unless the court for good cause finds it proper to require one." A conservator, who does manage the protected person’s property, has no such default exemption: § 633.174(2) requires "every conservator" to file bond except as § 633.175 separately provides, and § 633.175(2) is stricter for conservators than for any other fiduciary — the court can’t waive a conservator’s bond at all unless a court-approved non-bond asset-protection plan is on file, or the conservator is a financial institution with Iowa trust powers.
How much does an Iowa probate bond premium cost once the clerk sets the penal sum?
Premium is a percentage of whatever figure the § 633.170 formula produces, priced the way fiduciary bond carriers price nationally: roughly 0.5% to 1.5% of the bond amount per year, based mainly on the fiduciary’s personal credit rather than the estate’s complexity. Because Iowa’s formula is fixed rather than left to a judge’s discretion, you can run the math yourself before ever talking to an underwriter — see the worked example below, and our probate bond cost by state guide for how Iowa’s formula compares to states that leave the number to a judge.
