Michigan Letters of Authority
Michigan letters of authority guide for personal representatives handling banks, real estate, vehicles, claims, and estate records.
It is not legal advice. Verify current requirements with the county probate court, relevant agency, or qualified Michigan counsel before acting.
Michigan letters of authority are the court document a personal representative uses to show authority after appointment. Other states may call similar documents letters testamentary or letters of administration. In Michigan probate, families often see PC 572.
This guide provides general Michigan letters of authority information. Confirm current form, appointment status, and restrictions with the county probate court.
What Letters Of Authority Do
Letters of authority show that the probate court appointed a personal representative. Banks, title companies, vehicle offices, insurers, and other custodians may ask for certified letters before releasing information or property.
Letters do not make every act proper. The personal representative must still follow Michigan law, court limits, the will, creditor rules, and fiduciary duties.
How A Personal Representative Gets Letters
The estate usually needs an application or petition first. Informal probate often uses PC 558. Formal probate often uses PC 559. After appointment, the court can issue letters of authority, commonly PC 572.
The filing path depends on whether the estate is informal, formal, supervised, contested, or limited by a court order. Read Michigan probate court forms before filing.
What Letters May Be Used For
Letters may help the personal representative:
- Open an estate bank account
- Request account balances
- Transfer or sell estate property
- Work with title companies
- Handle vehicle title issues
- Pay valid claims and expenses
- Sign estate tax or information documents
- Communicate with creditors and beneficiaries
For the broader duty list, read Michigan executor duties.
Restrictions And Expiration Questions
Letters may have restrictions. A court order, supervised administration, bond issue, or limited appointment can affect what the personal representative may do.
Some recipients ask for recently certified letters. If a bank or title company rejects an older copy, ask the probate court how to obtain a fresh certified copy.
Foreign Personal Representatives
If the decedent lived outside Michigan but owned Michigan property, the home-state fiduciary may need to prove authority in Michigan or open a Michigan proceeding. Read Michigan ancillary probate before relying on out-of-state letters.
Records To Keep With Letters
Keep these records together:
- Certified death certificate
- Original or court-filed will
- Appointment order
- Letters of authority
- Bond information, if required
- Inventory and account records
- Deeds, titles, and account statements
- Receipts and closing documents
