Michigan Estate Planning Law: Wills, Trusts, and Powers of Attorney

Michigan estate planning law governs the legal instruments through which residents structure the transfer of assets, designate decision-makers, and manage affairs during incapacity or after death. The field encompasses wills, revocable and irrevocable trusts, powers of attorney, and healthcare directives — all of which are defined and regulated under the Michigan Compiled Laws. Estate planning intersects directly with the Michigan probate process, which administers estates through the court system when formal validation of documents is required. Understanding how these instruments are classified, executed, and enforced is essential for legal professionals, financial advisors, and anyone responsible for an estate in Michigan.

Definition and scope

Michigan estate planning law is primarily codified in the Estates and Protected Individuals Code (EPIC), enacted as Public Act 386 of 1998 and located at MCL 700.1101 through MCL 700.8102. EPIC consolidated and replaced earlier Michigan probate statutes, aligning the state with a framework derived from the Uniform Probate Code.

The core instruments recognized under Michigan law fall into three categories:

1. Testamentary instruments — Wills, including holographic and attested wills, which control the distribution of probate assets after death.
2. Trust instruments — Revocable living trusts, irrevocable trusts, testamentary trusts, and special needs trusts, which can transfer assets outside the probate system.
3. Incapacity instruments — Durable powers of attorney for finances (MCL 700.5501–700.5520) and patient advocate designations (healthcare proxies) under the Estates and Protected Individuals Code and the Patient Advocate Designation Act (MCL 700.5506).

Scope and coverage limitations: This page covers estate planning instruments governed by Michigan state law, specifically EPIC and related Michigan statutes. Federal estate tax law (governed by the Internal Revenue Code), federal Medicaid regulations under Title XIX of the Social Security Act, and multi-state or international estate issues involving assets held outside Michigan fall outside the scope of this reference. Tribal estate matters governed by sovereign tribal law are also not addressed here — see Michigan Tribal Law and Sovereignty for that distinct framework.

How it works

Execution requirements under EPIC establish specific formalities for each instrument type. A valid attested will in Michigan requires the testator to be at least 18 years of age, of sound mind, and to sign the will (or direct another to sign) in the presence of 2 witnesses who also sign the document (MCL 700.2502). Holographic wills — handwritten and signed by the testator without witness signatures — are recognized under MCL 700.2502(2), but they carry heightened risk of contest and are subject to strict authenticity standards.

Revocable living trusts must be created by a settlor with legal capacity, executed with a written trust agreement, and funded by transferring titled assets into the trust. Unlike wills, funded revocable trusts bypass probate entirely, which can reduce the time and cost of estate administration. Under MCL 700.7402, a trust is created only if the settlor has capacity, the intent to create a trust is manifest, and the trust has definite beneficiaries or qualifies as a charitable or honorary trust.

Durable powers of attorney for finances require notarization and, under MCL 700.5501, must be signed before a notary public or two witnesses. The document remains effective upon the principal's incapacity if designated as "durable." Patient advocate designations follow parallel requirements under MCL 700.5506.

The Michigan regulatory context for estate and probate matters situates these instruments within the broader administrative and judicial framework that governs their enforcement.

A numbered breakdown of the estate planning instrument execution sequence:

1. Assessment of assets — identifying probate versus non-probate property (beneficiary-designated accounts, jointly held real estate, trust-held assets).
2. Selection of appropriate instruments — determined by estate complexity, family structure, tax exposure, and incapacity risk.
3. Drafting by a licensed Michigan attorney under Michigan State Bar requirements.
4. Formal execution — witnessing, notarization, or holographic satisfaction per EPIC requirements.
5. Funding and titling — for trusts, actual transfer of assets is required to achieve non-probate transfer.
6. Periodic review — Michigan law does not mandate review intervals, but life events (marriage, divorce, death of a beneficiary) may affect instrument validity under EPIC's revocation-by-divorce rule (MCL 700.2807).

Common scenarios

Probate avoidance: A married couple holds a primary residence jointly with full rights of survivorship and establishes a revocable living trust for investment accounts, naming each other as co-trustees. At death, jointly held real estate passes by operation of law; trust assets pass to successor trustees without court involvement.

Blended families: A testator with children from a prior relationship uses a pour-over will combined with a revocable trust to direct assets to specific beneficiaries. Without explicit planning, Michigan's intestacy rules under MCL 700.2102 could allocate assets in proportions that do not reflect the decedent's intent.

Incapacity planning: A Michigan resident diagnosed with early-stage dementia executes a durable power of attorney designating a sibling as agent and a patient advocate designation naming a spouse for healthcare decisions. Execution while the principal still has capacity is legally critical — a power of attorney executed after loss of capacity is void.

Special needs trusts: A parent establishes a third-party special needs trust for an adult child receiving Supplemental Security Income (SSI). Assets held in a properly structured special needs trust are excluded from SSI resource calculations under federal Social Security Administration rules, preserving eligibility.

Small estates: Michigan offers simplified administration for estates with a gross value under $25,000 (MCL 700.3982), allowing collection of assets by affidavit without formal probate — a critical threshold for lower-value estates.

Decision boundaries

The choice between a will-centered plan and a trust-centered plan hinges on several structural factors:

Michigan property law intersects estate planning at the point of asset titling — how property is held at death determines whether a will or trust controls its disposition, or whether neither does (as with beneficiary-designated accounts).

Attorneys practicing estate planning in Michigan must be licensed through the State Bar of Michigan and are subject to the Michigan Rules of Professional Conduct. Specialized credentials such as the Certified Elder Law Attorney (CELA) designation, administered by the National Elder Law Foundation, are recognized in the field but are not required by Michigan statute.

Estate plans involving federal estate tax exposure are relevant only to estates exceeding the federal exemption threshold set annually by the IRS — for 2024, the federal estate tax exemption is $13.61 million per individual (IRS Revenue Procedure 2023-34). Michigan does not impose a state-level estate or inheritance tax as of the date EPIC was last substantively amended, making federal thresholds the operative tax boundary for most Michigan estates.

Disputes over will validity, trust administration, or agent conduct under a power of attorney are adjudicated in Michigan Probate Courts, which operate as divisions of the circuit court under MCL 700.1302.
