Michigan Guardianship by County: Wayne, Oakland, Macomb, and Kent Filing Differences

Why County Matters More Than You'd Expect

Michigan's 83 county probate courts all apply the same guardianship statutes — EPIC and the Mental Health Code — but each court's register enforces its own local procedural rules. Two families filing identical petitions on the same day can have completely different experiences depending on whether they're in Wayne County or Kent County.

The differences aren't trivial. Wayne County requires two local forms. Oakland County has specific same-day processing deadlines. Some counties mandate electronic filing through MiFILE; others still work from paper. Filing in the wrong format or missing a county-specific requirement means your packet may come back, and you lose however many weeks it takes to resubmit correctly.

Wayne County Probate Court

Wayne County is Michigan's largest probate court and adds the most local overhead to the standard SCAO filing packet.

Extra local forms required:

• WCPC 99 — Petitioner Filing Coversheet (unique to Wayne County)
• MC 505 — Contact Information Form

These are filed alongside the standard SCAO forms (PC 658 or PC 625, PC 571, MC 97, MC 97a). Without both, the clerk may return or reject the packet regardless of how complete your petition is.

Filing method: MiFILE electronic filing is accepted and increasingly expected. Paper filings are still possible at the downtown Detroit courthouse, but electronic filing avoids the parking and security line delays.

Fee payment: The $175 LII filing fee (DD petitions are free) can be paid by credit card through MiFILE, or by cash, check, or money order in person. Credit card payments through MiFILE carry a small processing surcharge.

Legal newspaper publication: If an interested party can't be located for personal service, Wayne County typically directs publication to the Detroit Legal News.

Oakland County Probate Court

Oakland County runs one of the busier suburban probate courts in Michigan, headquartered at the courthouse complex in Pontiac.

Same-day processing window: Petitions submitted before 4:00 PM on a business day are typically processed the same day. Anything arriving after that deadline rolls to the next business day, which can delay hearing scheduling by a week or more if you're close to a statutory deadline.

Electronic filing: Oakland County uses MiFILE. In-person filing at the Pontiac courthouse is available but less efficient.

Background checks: Oakland County requires criminal history background check authorization for prospective guardians. This isn't technically a local form — it's part of the court's standard vetting process — but if you don't proactively provide it, the court requests it and your timeline stalls.

Accounting policies: Oakland County has county-specific rules for in-person accounting reviews for conservatorship annual reports (PC 584). If you're filing for both guardianship and conservatorship, ask the register about the local accounting submission process at the time of initial filing.

Macomb County Probate Court

Macomb County's probate court is located in Mount Clemens and handles a high volume of guardianship petitions for Michigan's third-most-populous county.

Filing method: MiFILE is available. In-person filings at the courthouse are accepted during business hours.

Hearing scheduling: Macomb County typically schedules developmental disability guardianship hearings within the 30-day statutory window without issue. For LII petitions, hearing timelines can be slightly longer depending on court calendar availability and whether the Guardian ad Litem needs additional investigation time.

Remote hearings: Macomb has continued offering remote hearing options for certain guardianship proceedings post-pandemic. Confirm with the court register whether your specific hearing type qualifies for a video appearance, especially if the respondent has mobility limitations.

Kent County Probate Court

Kent County, centered in Grand Rapids, is the fourth-largest probate court in Michigan.

Filing procedures: Kent County accepts filings through MiFILE. The court's website provides county-specific guardianship filing guides that walk through each step for both the DD and LII tracks.

Fee structure: Standard SCAO fees apply — $175 for LII, $0 for DD, $20 for annual conservator reports. Fee waivers (MC 20) follow the statewide process.

Legal aid access: Kent County benefits from proximity to the Legal Aid of Western Michigan office, which can assist income-qualifying families with basic guardianship paperwork. However, contested guardianship representation through legal aid is rare — their resources are limited to document preparation and filing assistance for straightforward cases.

Key Takeaways Across All Counties

Regardless of which county you file in:

• Serve the respondent personally at least 7 days before the hearing (or serve interested parties by mail at least 14 days before). Missing service deadlines postpones the hearing.
• File Proof of Service (PC 564) on or before the hearing date. Missing proof of service may postpone the hearing.
• DD track petitions require the PC 659 evaluation report completed within one year. Waiting to get this evaluation after filing adds the time required for Community Mental Health to conduct one.
