When someone you love dies, the legal system doesn’t wait for you to catch your breath. Bills keep arriving. Bank accounts get frozen. The mortgage company wants answers you don’t have yet. And somewhere in the middle of all of it, someone tells you that you need to “open probate.”

For Oakland County families, that means navigating one of Michigan’s busiest probate courts – often with no legal background and no idea where to start. The process is manageable, but only when you understand what you’re walking into and who can help you through it.

This guide covers what Oakland County probate actually looks like in 2026, what it costs, how long it takes, and when hiring a local probate attorney isn’t optional – it’s the difference between resolving the estate and getting stuck in it.

Understanding Oakland County Probate Court

Oakland County Probate Court is located at 1200 N. Telegraph Rd., Building 12 East, Pontiac, MI 48341. The court can be reached at (248) 858-0250 or through its official website.

Four judges currently serve on the Oakland County Probate bench:

• Hon. Jennifer S. Callaghan (Chief Judge)
• Hon. Daniel A. O’Brien (Chief Judge Pro Tempore)
• Hon. Kathleen A. Ryan
• Hon. Traci Richards

A critical development for families filing in 2026: Oakland County Probate Court went live on MiFILE – Michigan’s statewide electronic filing system – on June 12, 2025. This means petitions, inventories, accountings, and most other probate filings can now be submitted electronically rather than in person or by mail. For families and attorneys who understand the system, e-filing reduces trips to Pontiac and speeds up processing. For those who don’t, it adds a layer of confusion to an already stressful process.

When Is Probate Required in Michigan?

Not every estate needs probate. Understanding when the court process is required – and when it isn’t – can save families months of time and thousands in fees.

Probate is generally required when a deceased person owned assets solely in their name with no beneficiary designation, payable-on-death arrangement, or joint ownership. Common examples include individually titled real estate, bank accounts without POD designations, and vehicles.

Probate is typically not required when assets pass through other mechanisms: jointly held property with rights of survivorship, retirement accounts and life insurance with named beneficiaries, assets held in a revocable living trust, and vehicles or watercraft that qualify for transfer by affidavit under MCL 257.236.

Many Oakland County families don’t realize that whether probate is needed depends on how assets are titled – not on whether a will exists. A will doesn’t avoid probate. It tells the probate court what to do. A trust, on the other hand, can keep assets out of court entirely.

Step by Step: The Oakland County Probate Process

Filing the Petition or the Application

The process begins when someone – usually the person named in the will or a close family member – files a petition or application with Oakland County Probate Court asking the court to open the estate. Along with the petition or application, you’ll submit the original will (if one exists), a certified death certificate, a number of other documents, and the applicable filing fee.

Most Oakland County estates proceed through informal probate under MCL 700.3301 et seq., which allows the personal representative to manage the estate without court involvement in every decision. Contested estates or those involving vulnerable beneficiaries may require supervised administration under MCL 700.3501, where the court maintains closer oversight.

Appointment as Personal Representative and Letters of Authority

Once the court approves the initial filing, it appoints a personal representative – Michigan’s legal term for the person responsible for managing the estate. The court then issues Letters of Authority, the document that gives the personal representative legal power to act on behalf of the estate.

Without Letters of Authority, banks won’t release funds. Title companies won’t process transfers. Financial institutions won’t even speak with you about the decedent’s accounts. This document is the key that unlocks the entire administration process.

An important clarification: Letters of Authority do not automatically expire each year. This is a common misconception. Once issued, they remain legally in effect. However, as a practical matter, most banks, government agencies, and financial institutions will require updated letters each year before they’ll accept them. Your probate attorney can help you obtain refreshed letters from the court when needed.

What does have a hard deadline is the 91-day inventory requirement – under MCL 700.3706, the personal representative must prepare and distribute a sworn inventory of estate assets within 91 days of appointment. Missing this deadline can trigger court intervention and erode the court’s confidence in the personal representative’s ability to manage the estate.

Notice to Creditors and Publication

The personal representative must publish a notice to creditors in an Oakland County newspaper approved by the court. Under MCL 700.3801 et seq., creditors then have four months from the date of publication to file claims against the estate.

This four-month window is mandatory. It cannot be shortened, even for simple estates. Publication costs vary but typically run around $150-$200 as an example – the actual amount depends on the publication outlet.

Separately, the personal representative must send formal notice to all known heirs and beneficiaries, whether named in the will or entitled under Michigan’s intestacy laws.

Inventory and Appraisal

The personal representative must identify, secure, and value every probate asset – real estate, bank accounts, investment accounts, vehicles, business interests, and personal property. A sworn inventory is filed with the court within the 91-day window required by MCL 700.3706.

Not everything the deceased owned passes through probate. Assets with beneficiary designations, jointly held property, and trust-held assets generally pass outside the probate estate. But documenting everything – including non-probate assets – protects the personal representative and reduces disputes among beneficiaries later.

Payment of Debts and Taxes

Using estate funds, the personal representative pays funeral expenses, valid creditor claims, administration costs (including attorney fees and personal representative compensation), and any required taxes. Michigan law establishes a strict priority order for these payments. Distributing assets to beneficiaries before debts are settled can expose the personal representative to personal liability – a risk that catches many first-time executors off guard.

Final Distribution and Closing

After the creditor period expires and all obligations are satisfied, the personal representative distributes remaining assets according to the will – or under Michigan’s intestacy statutes if there is no will. The personal representative then files either a formal accounting and petition for complete settlement, or Michigan’s “Sworn Statement to Close Unsupervised Administration” for simpler cases.

How Long Does Probate Take in Oakland County?

Straightforward, uncontested estates in Oakland County typically take 7 to 12 months from petition to closing. The mandatory four-month creditor period accounts for the bulk of that minimum timeline, with the remaining months devoted to asset gathering, debt payment, tax filings, and distribution.

Contested estates – those involving disputes among heirs, will challenges, or complex assets like business interests or multiple properties – routinely take 9 to 18 months and sometimes longer.

The personal representative’s organization and responsiveness are the single biggest factors families can control. Filing promptly, responding immediately to court notices, and working with experienced Michigan probate counsel keeps estates on the faster end of these timelines.

How Much Does Probate Cost in Oakland County?

Probate costs add up across several categories. Here’s what Oakland County families should realistically expect:

• Court filing fees run approximately $175 for the initial petition or application, plus additional costs for subsequent filings.

• Publication costs for the creditor notice typically run $150–$250, depending on the outlet.

• Attorney fees for probate administration generally range from $300–$500 per hour, and straightforward probate administration typically costs $10,000–$15,000 in total.

• The inventory fee assessed by the court runs 1–3% of estate value.

• Personal representative compensation, appraisal costs, and accounting fees add further.

For a moderately sized Oakland County estate, families should budget for total probate costs ranging from roughly 3% to 7% of the estate’s gross value. That’s a significant expense – and one of the most compelling reasons to explore probate avoidance strategies before they’re needed.

Oakland County Small Estates: A Faster Path

Michigan law provides a streamlined alternative for smaller estates that can save families significant time and money.

Under MCL 700.3982 and MCL 700.3983, estates valued at $50,000 or less in probate assets may qualify for simplified small-estate procedures – either a small-estate petition or collection by affidavit. This threshold is adjusted annually, so families should confirm the current figure at the time of filing. When the estate qualifies, these tools can reduce a months-long process to a matter of weeks and eliminate thousands in court and attorney fees.

An important note: following amendments to MCL 700.3983, certain real property may be included in the affidavit process under specific conditions. This is a meaningful change from prior law, which generally excluded real estate from small-estate affidavits. The eligibility requirements are specific, however, and using small-estate procedures incorrectly can create bigger problems than full administration would have. A brief consultation with a probate attorney is the most efficient way to determine whether this shortcut fits your family’s situation.

At Boroja, Bernier & Associates, small estate assistance typically costs $1,500-$3,000 for straightforward affidavit preparation and guidance – a fraction of full probate administration.

Why Probate in Oakland County Requires a Local Attorney

Oakland County’s transition to MiFILE e-filing, its four-judge bench, and its position as one of Michigan’s highest-volume probate courts all create dynamics that reward familiarity with local practice.

A probate attorney who regularly files in Oakland County understands how the court’s electronic filing system works, which filing errors trigger rejections, and what each judge expects in terms of documentation and procedure. That familiarity translates directly into fewer delays, fewer rejected filings, and a smoother experience for families who are already dealing with enough stress.

In our experience handling Oakland County estates, the most common mistake families make isn’t a legal error – it’s waiting too long to start. Probate timelines are measured in months, and every week of delay at the beginning compounds into longer waits at the end.
