Quick answer: the biggest delay risks in Michigan are skipping creditor notice publication, ending up in supervised administration, and a disallowed claim that goes to a lawsuit. Estimate your own timeline with the Michigan probate timeline calculator.
1. Skipping or botching creditor notice publication
2. Ending up in supervised administration
Supervised administration requires court approval for nearly every significant action — selling an asset, paying a claim, making a distribution. That ongoing oversight is why it routinely runs well past informal administration's typical timeline, and it's the track disputes among heirs or an uncertain will often push an estate into.
3. A disallowed claim that turns into a lawsuit
When a personal representative formally disallows a creditor's claim, the creditor has 63 days to sue on it or lose it for good. If they do sue, resolving that lawsuit — discovery, a hearing, a ruling — adds real time the estate wouldn't otherwise need before it's safe to close.
4. Real estate that needs to be sold
Selling estate real estate adds its own appraisal, listing, and closing timeline. Under supervised administration, that sale may also need separate court approval, while informal administration generally allows more flexibility to proceed without a hearing at each step.
