Estate planning is often driven by wanting to LEAVE things to people. But sometimes it's driven by wanting to leave things AWAY from people - a specific adult child, an estranged sibling, a former stepchild. Michigan generally lets you disinherit almost any family member EXCEPT your surviving spouse (Michigan MCL 700.2202 grants spouses an "elective share" that overrides the will). Doing this right requires specific language, a contest-resistant document, and careful planning to prevent your wishes from being unwound after your death. This guide covers exactly who you can and cannot disinherit in Michigan, the exact language attorneys use, and how to add layers of protection so your disinheritance actually holds up.
The 30-Second Answer
- Adult children: fully disinheritable in Michigan. No forced heirship for adult children.
- Minor children: generally disinheritable, but Michigan homestead allowance (MCL 700.2402), family allowance (MCL 700.2403), and exempt property (MCL 700.2404) still apply.
- Grandchildren, siblings, parents, cousins: fully disinheritable.
- Spouse: CANNOT be fully disinherited. Michigan MCL 700.2202 grants the surviving spouse an "elective share" of roughly one-half of the augmented estate. Only prenuptial or postnuptial agreements can waive this.
- Cohabiting partners: Michigan does not recognize common-law marriage, so unmarried partners have no automatic inheritance rights and don't need to be disinherited (they get nothing by default).
- Best practice: use explicit disinheritance language, a no-contest clause, and a Michigan-compliant witnessed will (see our witness requirements guide).
Who You CAN Disinherit in Michigan
Under Michigan's Estates and Protected Individuals Code (EPIC), the following categories can be completely disinherited from your Michigan will:
Adult Children
Michigan does NOT protect adult children from disinheritance. You can leave any adult child (or all your adult children) $0 with no legal recourse - provided your will properly disinherits them (see language below). This is different from some states (Louisiana, for example) which have "forced heirship" for children.
Minor Children (Mostly)
Michigan can disinherit minor children from specific bequests, but three protections remain:
- Homestead allowance: MCL 700.2402 grants the surviving spouse OR minor/dependent children $27,000 in 2026 (adjusted annually)
- Family allowance: MCL 700.2403 permits Michigan probate court to grant reasonable support for surviving spouse and minor children during estate administration (typically $2,000-$5,000/month)
- Exempt property: MCL 700.2404 sets aside $10,000 (2026 inflation-adjusted) in household furniture, cars, appliances, and personal effects for the surviving spouse or minor children
You can waive these in a Michigan prenuptial agreement but not in a will alone.
Grandchildren
Fully disinheritable. Michigan does not recognize any inherent inheritance right for grandchildren unless their parent (your child) predeceased you and Michigan's anti-lapse statute (MCL 700.2603) applies.
Siblings, Parents, Cousins, In-Laws
Fully disinheritable. Michigan intestate succession rules under MCL 700.2101-2106 only reach siblings if there is no will AND no closer relatives. Since your will controls, you can leave them $0.
Adopted Children
Michigan treats legally adopted children the same as biological children under MCL 700.2114. They can be disinherited on the same terms as any adult child.
Stepchildren
Michigan does NOT treat stepchildren as heirs by default (unless legally adopted by you). Stepchildren inherit nothing under Michigan intestate succession, so no active disinheritance is needed.
Former Spouses
Michigan MCL 700.2807 automatically revokes an ex-spouse from wills, revocable trusts, and beneficiary designations upon divorce (with the ERISA exception for employer group life insurance - see our Michigan divorce & estate plan guide).
Who You CANNOT (Fully) Disinherit
Your Surviving Spouse - Michigan Elective Share (MCL 700.2202)
Michigan strongly protects surviving spouses. If you leave your spouse LESS than roughly one-half of the "augmented estate" (calculated under MCL 700.2202), your spouse can:
- File a Michigan election with probate court within 63 days of the will being admitted (or 6 months after inventory filing, whichever is later)
- Claim the "elective share" - roughly 50% of the augmented estate (including certain assets you thought you gave away)
- Override your will completely as to that share
The augmented estate includes probate assets PLUS:
- Life insurance proceeds
- Retirement account balances
- Gifts made within 2 years of death
- Assets in revocable trusts
- Joint-tenancy property
Michigan spouses can WAIVE the elective share via:
- Prenuptial agreement (Michigan Uniform Premarital Agreement Act, MCL 557.28-32)
- Postnuptial agreement (case-law based, harder to enforce)
- Written waiver signed with full disclosure and independent counsel
If you want to disinherit your Michigan spouse, DIY tools are insufficient - hire a Michigan family law attorney for a prenup/postnup. This is one situation where the $89 will kit alone will not accomplish your goal.
The Right Michigan Disinheritance Language
Michigan probate courts require CLEAR intent to disinherit. Ambiguous language can be interpreted against the disinheritance. Attorney-recommended templates:
Explicit Named Disinheritance
"I have intentionally and with full knowledge omitted to provide for my son [FULL NAME], born [DATE], in this Last Will and Testament. This omission is not an oversight and no bequest of any kind is intended for him. Any share of my estate that would otherwise pass to [NAME] shall pass instead to [ALTERNATE BENEFICIARY]."
Class Disinheritance
"I have intentionally omitted to provide for any and all children born to me or adopted by me who are not specifically named in this Will. This omission is deliberate and no share of my estate is intended for any unnamed child."
Nominal Bequest (Alternative Strategy)
Some Michigan attorneys recommend leaving a small nominal bequest ($1, $100) rather than complete disinheritance:
"To my daughter [FULL NAME], born [DATE], I bequeath the sum of One Hundred Dollars ($100.00) and no more, in full and complete satisfaction of any claim she may have against my estate."
Argument for nominal bequest: proves you didn't "forget" your daughter (blocking pretermitted heir claims) and gives you a specific dollar sum to reference in a no-contest clause.
Reason Statement (Optional)
Some testators include a brief explanation:
"My decision to omit [NAME] from this Will reflects our estrangement over the past [X] years and is not the result of any confusion, undue influence, or diminished capacity on my part."
Warning: reason statements can BACKFIRE if the "reason" is inflammatory or factually contested. Michigan attorneys are split on whether to include them. If you do, keep it factual, brief, and non-defamatory.
No-Contest Clauses under MCL 700.2518
A "no-contest clause" (sometimes called an "in terrorem clause") threatens forfeiture of any bequest for a beneficiary who challenges the will. Michigan MCL 700.2518 allows no-contest clauses but they are NOT enforced against a contest brought with "probable cause."
Standard Michigan No-Contest Language
"If any beneficiary under this Will, either directly or indirectly, contests or attempts to contest the validity of this Will or any of its provisions, that beneficiary shall forfeit any interest under this Will, and I direct that such beneficiary shall be treated as though they had predeceased me."
Why Nominal Bequests Amplify the No-Contest Clause
If you leave a disliked family member $0, they have nothing to lose by contesting - the no-contest clause is toothless. If you leave them $500, they now face a choice: keep $500 or gamble on a $50,000 contest. Most rational relatives take the $500. Michigan case law generally supports this "meaningful stake" approach.
Probable Cause Exception
Michigan MCL 700.2518 does NOT enforce no-contest clauses when the contestant has "probable cause" to contest (e.g., legitimate concerns about the testator's capacity or undue influence). Purely retaliatory contests DO trigger the clause.
Making Your Michigan Disinheritance Contest-Proof
Michigan disinheritance is most vulnerable to challenges on three grounds. To defend against each:
1. Testamentary Capacity Challenge
Contestant claims you weren't of "sound mind" when signing. Defense:
- Sign your will WELL before any dementia or serious illness diagnosis
- Include a "capacity affidavit" signed by your primary care physician within 30 days of signing
- Record a brief video (2-5 minutes) of yourself explaining your wishes coherently
- Use the Michigan self-proving affidavit under MCL 700.2504
2. Undue Influence Challenge
Contestant claims you were manipulated by another family member. Defense:
- Do NOT use the primary beneficiary as a witness or notary
- Sign the will at your own home, at a bank, or in an attorney's office - NOT at the beneficiary's home
- Do NOT have the primary beneficiary transport you to the signing appointment
- Document that you understand what you're signing (multiple witnesses can confirm this)
3. Fraud / Forgery Challenge
Contestant claims someone forged your signature or substituted pages. Defense:
- Initial every page in ink at the bottom right corner
- Use consistent paper stock and formatting throughout
- Sign with your usual signature style
- Use a self-proving affidavit with notarization
Using a Trust to Add Layers of Protection
A Michigan revocable trust is more difficult to contest than a will because:
- Trusts are not part of the public probate record - the disinherited person may not learn of the disinheritance until well after your death
- Michigan Trust Code (MCL 700.7100 et seq.) requires the contestant to prove capacity and undue influence issues at a HIGHER standard than for a will
- Trust distributions can be delayed to allow contest periods to expire
- Trust "silent" provisions can conceal disinheritance from public view
For serious disinheritance situations, layer a revocable trust ON TOP OF a Michigan will:
- Sign a Michigan revocable trust that contains the disinheritance language
- Fund the trust with your major assets (retitle real estate, bank accounts, etc.)
- Sign a Michigan "pour-over will" that catches any unfunded assets and sends them to the trust
See our Michigan living trust cost guide.
Five Common Michigan Disinheritance Mistakes
1. "I Just Won't Mention Them"
Silence is dangerous. Michigan's pretermitted heir doctrine (MCL 700.2302) can grant an omitted heir a share if the omission appears unintentional. Say it explicitly.
2. Using Vague Language
"I don't want my son to inherit anything" is weaker than "I have intentionally and with full knowledge omitted to provide for my son [FULL NAME]." Precision matters.
3. Naming a Disinherited Person as Executor
Never name someone you're disinheriting as your executor/personal representative. They have both motive and access to obstruct estate administration.
4. Storing the Will Where the Disinherited Person Can Access It
Some Michigan will contests are solved by simply making the original disappear. Store your will securely (see our Michigan will storage guide).
5. Waiting Too Long
Disinheritance is much harder to defend when signed weeks before death. Sign years earlier, ideally in good health, with contemporaneous documentation.
Frequently Asked Questions
Can I disinherit my spouse if we're separated but not divorced?
No, not fully. Under Michigan law, a separated (not divorced) spouse retains full elective share rights under MCL 700.2202. Complete divorce is required to eliminate spousal inheritance rights.
Can I disinherit my child if they have a disability?
Legally yes, but consider the consequences. Michigan special needs trusts allow you to provide for a disabled child WITHOUT disqualifying them from SSI, Medicaid, and other means-tested benefits. Consult a Michigan attorney about a "third-party special needs trust" under 42 USC 1396p(d)(4)(A).
Can I disinherit my child by leaving them $1?
Yes - this is the "nominal bequest" strategy. Combined with a no-contest clause, $1 (or preferably $100-$500) is often more effective than $0.
What if my disinherited child gets legal advice and challenges the will?
Michigan probate courts entertain the challenge. If the challenge is with probable cause, the will contest proceeds and no-contest clauses may not apply. If without probable cause, the no-contest clause forfeits the challenger's bequest.
Can I "conditionally" disinherit (e.g., if my son marries again)?
Michigan generally enforces reasonable conditions on bequests. Public-policy-violating conditions (racist, religious, or grossly unfair) are typically struck down. Consult a Michigan attorney for anything unusual.
Does Michigan allow disinheritance based on lifestyle choices?
Yes, generally. You can disinherit for any reason or no reason, provided the disinheritance itself is clearly stated. Michigan courts do NOT require justification.
What if the disinherited person predeceases me?
Their share (if any) does not pass to their descendants by default UNLESS your will provides otherwise. Michigan's anti-lapse statute (MCL 700.2603) only applies to bequests to a "class" of relatives.
Can I use a Michigan trust to disinherit and prevent notification?
Michigan Trust Code (MCL 700.7813) generally requires the trustee to notify "qualified beneficiaries." Disinherited persons are NOT qualified beneficiaries and typically receive no notice - they may not learn of the trust for years.
Should I tell the disinherited person during my lifetime?
Legally not required. Emotionally, some estate planners recommend a written letter (kept separate from the will) explaining your reasoning. This can reduce post-death contest motivation. Others recommend against it because it may prompt lifetime litigation.
Can I disinherit and still leave a small "quiet" bequest?
Yes - the nominal bequest strategy. $100-$500 is enough to create a "meaningful stake" for no-contest purposes without giving the disinherited person meaningful money.
What if a disinherited child was a caregiver?
Michigan recognizes "quantum meruit" claims for uncompensated caregivers who provided services to the deceased. If your disinherited caregiver-child sues for compensation for years of caregiving, they may recover fair market value of services separately from any inheritance. Consult a Michigan attorney if this may apply.
Can adopted children be disinherited the same as biological children?
Yes. Michigan MCL 700.2114 treats legally adopted children the same as biological children. Same disinheritance rules apply.
