Which County to File Divorce in Iowa

Iowa's Two-Layer Venue Rule

Filing your Iowa dissolution of marriage in the wrong county is one of the fastest ways to delay your case by months. The statute looks simple — Iowa Code Section 598.2 says you file where either you or your spouse lives — but there's a practical residency layer underneath that catches people who've recently moved.

The Statutory Rule: Your County or Theirs

You have two options for venue:

• The county where you (the petitioner) currently reside
• The county where your spouse (the respondent) currently resides

If you both live in the same county, that's your only option. If you live in different Iowa counties, you pick one. The filing fee is $285 regardless of which county you choose.

One scenario that confuses people: if your spouse moved to another state before you file, you can still file in your own Iowa county. But you'll need to meet the one-year Iowa residency requirement (Iowa Code Section 598.5) since the respondent isn't an Iowa resident who can be served in-state.

The 90-Day County Residency Expectation

Here's the part that isn't in the basic instructions. Iowa family law practice frequently references a 90-day county-specific residency expectation. It works like this: if neither party has lived in the county where you filed for at least 90 days, your spouse can file a motion to transfer the case to the proper county — or to dismiss it entirely.

This rule targets intra-state venue shopping, where someone files in a county they perceive as more favorable even though neither spouse lives there. But it also catches legitimate situations:

• Recent relocation within Iowa. You moved from Scott County to Johnson County two months ago. Filing in Johnson County is technically allowed under the statute, but your spouse could challenge venue because you haven't hit the 90-day mark yet. Filing in Scott County (where you previously lived, and possibly where your spouse still lives) is safer.
• Temporary housing. If you're staying with family in a different county after separating, but your permanent address is still in your original county, file in the original county. Temporary presence doesn't establish county residency.

How to Pick the Right County

Run through these questions in order:

1. Have you lived in your current county for at least 90 days? If yes, file there.
2. If not, has your spouse lived in their county for at least 90 days? If yes, file in their county.
3. If neither of you has 90 days in any Iowa county (both recently moved to Iowa from out of state), your case is vulnerable to a venue challenge; consider waiting until one of you has the 90-day county foothold. You also need to satisfy the state-level residency requirement first — if your spouse isn't an Iowa resident, you need one full year of continuous Iowa residency before filing.

What Happens If You File in the Wrong County

Your spouse can file a motion to challenge venue. If the court agrees, the case gets transferred to the correct county. That transfer adds weeks, sometimes months, to your timeline. The 90-day waiting period under Iowa Code Section 598.19 is tied to the applicable service date, but do not assume that other procedural deadlines will be unaffected; confirm with the court how pending deadlines are handled after a transfer.

In the worst case, if your filing had other deficiencies, the court can dismiss the case outright rather than transfer it. Then you're refiling from scratch, paying $285 again, and re-serving your spouse.

Residency Proof the Court Expects

Iowa Code Section 598.9 requires corroboration of residency — the court won't take your word for it alone. To prove you live in the county where you're filing, keep these ready:

• Iowa driver's license or state ID showing your county address
• Voter registration records
• Utility bills (electric, gas, water) in your name at the county address
• Lease agreement or mortgage deed
• State income tax returns listing the county address

If your residency is challenged, be prepared to provide a corroborating witness or other competent independent evidence. Check the court's instructions for whether it requires a written affidavit or testimony.

Planning Your Filing

County selection is the first procedural decision in your Iowa divorce, and getting it right prevents the most avoidable delays. The Iowa Divorce Filing Process Guide includes a residency verification checklist that walks through the state and county requirements step by step — so you can confirm your venue before you pay the filing fee and upload your petition to EDMS.
