How to Amend a Michigan Trust Yourself: The DIY Trust Amendment Guide

Your kid got married. Your sister was supposed to be the successor trustee but you had a falling out. The cottage went to your nephew but he passed away last year. Your bank changed names twice. The Michigan estate planning attorney who drafted your trust ten years ago is retired. Now what? Many Michigan trust holders assume that amending a revocable trust is a $1,500 attorney visit. It is not. Under MCL 700.7602, a trust amendment in Michigan can be a single typed page that you sign, date, and notarize. The law is intentionally flexible: as long as you "substantially comply" with the amendment process in your original trust (or with a clearly intentional writing if the trust is silent), the change is enforceable. This guide walks through exactly how to do it, what to include, what to avoid, and when a restatement is the better tool.

The 30-Second Answer

For a revocable Michigan trust, you can amend it yourself by drafting a written amendment that (a) clearly identifies the trust by name and date, (b) specifies which sections or provisions are being changed, (c) states the new language exactly as it should read, (d) is signed and dated by you as settlor, and (e) is ideally notarized (not legally required but strongly recommended). Most Michigan trusts include an amendment procedure in the trust itself -- read your trust first and follow that procedure. If you have already amended the trust multiple times, consider a full restatement instead of stacking amendments. Total DIY cost: free if you draft it yourself; $25-$50 if you use a template; one notary fee of about $10 if your bank or UPS Store does it for free.

What Michigan Law Actually Requires

The Michigan Trust Code controls amendments. The key section is MCL 700.7602, which states three things that matter for DIY amendments:

• 700.7602(1): "Unless the terms of a trust expressly provide that the trust is irrevocable, the settlor may revoke or amend the trust." Translation: revocable trusts can be amended by the settlor at any time. Trusts created on or after April 1, 2010 are presumed revocable unless they state otherwise.
• 700.7602(3)(a): The settlor amends the trust by "substantially complying with a method provided in the terms of the trust." Translation: read your trust. It almost certainly has an amendment paragraph. Follow whatever procedure it specifies.
• 700.7602(3)(b): If the trust does not specify a method, or specifies a non-exclusive method, the settlor amends by (i) any later will that expressly refers to the trust, or (ii) any other writing that manifests the settlor's clear and convincing intent to amend.

Notice what is NOT required. Per the analysis at Will.com, "Michigan does not impose a general witness or notarization requirement for trust validity (MCL §§700.7401--700.7402)." Trust amendments inherit the same flexibility. You do not need two witnesses (unlike a will, which requires two under MCL 700.2502). You do not need a notary. You technically do not even need a typed document -- handwritten amendments are valid if dated and signed.

That said, every Michigan estate planning attorney recommends notarization. Per the breakdown at CF Legal in Flint: "Michigan law doesn't technically require witnesses or notarization for trust amendments, but most experienced trust update attorneys strongly recommend both. Proper execution with notarization establishes clear evidence of your capacity and intent." A $10 notary signature is the cheapest insurance against a future challenge.

Amendment vs. Restatement

Michigan trust holders typically have two options when they want to change a trust:

Amendment

A standalone document that changes specific provisions while leaving the rest of the trust intact. Best when you have one or two small changes -- changing a beneficiary, swapping the successor trustee, updating a charitable gift, or adding a recently-born child. You stack the amendment on top of the original trust. The original trust and all prior amendments together control.

Restatement

A document that rewrites the entire trust from scratch, while preserving the original trust's legal identity (same name, same date of original creation, same tax ID number if it has one). The restatement says "this restated trust replaces the original trust dated X" and then provides a complete new set of provisions. The original trust and all prior amendments are superseded entirely. Best when you have made three or more amendments, when you want to clean up confusing language, when laws have changed enough to merit a rewrite, or when more than ten years have passed since the original.

Per the analysis at CF Legal's Flint trust update guide, "For families with multiple changes needed, a restatement often provides cleaner documentation and prevents confusion from having multiple amendments." A restatement avoids the situation where a successor trustee or court has to reconcile six amendments stacked on top of an original from 2008.

A rule of thumb: if you would have to look at three or more documents to figure out what the current rules are, restate. If one amendment will fix the issue, amend.

The DIY Amendment Process Step-by-Step

1. Pull out your original trust document. Find the amendment paragraph. It usually appears near the end and says something like "I reserve the right to amend, modify, or revoke this trust by a writing signed by me and delivered to the trustee." Or it may say "by a writing acknowledged before a notary public." Whatever the trust says, you must "substantially comply" with that method. This is the single most important step -- if you ignore the trust's own amendment paragraph, your amendment may fail.
2. Identify the trustee on the original trust. If you are the trustee (most common in revocable living trusts), you only need to sign the amendment and place it with the trust records. If someone else is the trustee, the amendment may need to be delivered to them. Read the trust.
3. Write out exactly what you want to change. Be specific. "I amend Article IV, Paragraph 3 of the John Doe Revocable Living Trust dated January 15, 2018, by removing the bequest of '$10,000 to my niece, Susan Smith' and replacing it with '$15,000 to my niece, Susan Smith-Johnson, of Royal Oak, Michigan.'" Vague language ("I now want my nephew to get more") is what gets amendments invalidated.
4. Draft the amendment as a standalone document. Title it "First Amendment to the [Name of Trust] Trust" (or "Second Amendment," etc.). Include the trust name and date in the first paragraph. Include the changes in clear numbered paragraphs.
5. Sign and date the amendment. Sign exactly as you signed the original trust -- if the original is signed "John A. Doe," sign the amendment "John A. Doe." Consistency matters if anyone later challenges.
6. Notarize it. Take it to any bank, UPS Store, AAA branch, or Michigan Secretary of State office. Notarization is free at many Michigan banks if you have an account there. The notary will witness your signature, stamp the document, and record the act in their journal. A notarized signature is virtually unchallengeable.
7. Attach it physically to the original trust. Staple the amendment to the original trust binder or store both together in the same envelope/file. The successor trustee needs to find both documents together.
8. Distribute copies. Give a copy to your successor trustee, to your spouse if applicable, and to anyone else who already has a copy of the original trust. If the trust was registered with the probate court, file a copy there (this is rare; most Michigan trusts are not registered).
9. Update your asset records. If the amendment changes the trust's name (which a restatement usually does not), retitle assets. If you changed a beneficiary, no asset retitling is needed -- the trust still owns the assets, only the distribution provision changed.

Sample Trust Amendment Structure

Two Mistakes That Get Amendments Thrown Out

The Michigan Court of Appeals has a small but instructive line of cases about trust amendments. The two failure patterns:

Mistake 1: Ignoring the amendment procedure in the trust itself

In In re Bisbikis Trust, the trust required amendments to be made "by signing a writing specifically referring to this Trust Agreement and indicating the intent to alter or amend, whether or not such writing be witnessed or notarized." The settlor wrote a long letter to his wife describing how he wanted assets distributed but never specifically referenced the trust or used the word "amend." The court refused to enforce the letter as a trust amendment. Per GGTM Law's analysis, the court held that "substantial compliance" still requires actually referring to the trust.

Lesson: always explicitly reference the trust by name and date in your amendment, and use the word "amend" (not "change my will," "want to add," or similar vague language).

Mistake 2: Ambiguous or contradictory language

If the amendment can be read two different ways, a court will not enforce it as you intended. Common ambiguities: writing "to my children equally" when you have three biological children and two stepchildren (the stepchildren are usually NOT included in "my children" -- see our stepparent inheritance guide). Writing "to be divided fairly" without specifying percentages. Writing "I want my house to go to John" without specifying which house or which John.

Lesson: be specific. Name people by full legal name. Identify property by full description (the house at 123 Main Street, Pontiac, Michigan 48340). Specify dollar amounts or percentages, not "fair shares."

10 Life Events That Should Trigger a Michigan Trust Amendment

If any of these apply to you and you have not amended your trust in the last 12 months, it is time:

1. Marriage, divorce, or remarriage
2. Birth or adoption of a child or grandchild
3. Death of a named beneficiary or successor trustee
4. Move to or from Michigan (other states have different rules)
5. Significant change in assets -- buying or selling a home, business, or cottage
6. Beneficiary becomes disabled (may need a special needs trust amendment)
7. Beneficiary develops addiction, financial problems, or relationship issues that affect inheritance plans
8. Change in tax law (the 2025 OBBBA $15M estate tax exemption is a recent example -- see our estate tax 2026 guide)
9. Successor trustee moves out of state, becomes incapacitated, or is no longer suitable
10. Banks or brokerages have merged/renamed (rare to require amendment, but may want updates to "schedule of assets")

Per our when to update your Michigan estate plan guide, even without a major life event you should review your trust every three to five years.

What If My Trust Is Irrevocable?

Irrevocable trusts cannot simply be amended by the settlor. By signing the trust as "irrevocable," you gave up the right to change it on your own. But Michigan law provides four paths to modify an irrevocable trust if circumstances change:

• Beneficiary consent (MCL 700.7411): if all beneficiaries (including all contingent beneficiaries) consent in writing and the modification does not defeat a material purpose of the trust, the court may approve the change.
• Court modification for changed circumstances (MCL 700.7412): the court may modify the trust if continued administration on the original terms would be impracticable, wasteful, or impair the trust's accomplishment of its purpose.
• Decanting: the trustee can sometimes "pour" assets from the original irrevocable trust into a new trust with updated terms. This requires specific authority in the original trust or court approval, and may have tax consequences.
• Nonjudicial settlement agreement: all interested parties sign an agreement modifying the trust without going to court. Available only for certain types of changes.

All four paths are more complex than a revocable-trust amendment and usually require attorney involvement. This article is for the much more common scenario -- you have a revocable living trust you want to update yourself.

Frequently Asked Questions

Do I need an attorney to amend my Michigan trust?

No. There is no Michigan statute requiring attorney involvement in a trust amendment. Most Michigan attorneys recommend their use only because attorneys frequently see DIY amendments that fail one of the two mistakes above (ignoring the trust's own amendment procedure, or ambiguous language). If you read your trust's amendment paragraph carefully and follow the structure in this guide, you can do this yourself.

Does my spouse need to sign the trust amendment?

Only if your trust is a joint trust (one trust shared between you and your spouse as co-settlors). For a single-settlor revocable trust, your signature alone is sufficient. If your trust is joint, both spouses must sign all amendments unless the trust specifically allows one spouse to amend alone.

Can I just cross out language in the original trust and initial it?

Strongly discouraged. While Michigan case law has occasionally upheld handwritten changes (the Stillwell case is one example), the much safer route is a separate amendment document. Crossing out language in the original creates ambiguity, raises authenticity questions, and invites challenges. Always draft a separate amendment.

Do I need to record the amendment with the county?

No. Trusts are private documents in Michigan and are not recorded with the county Register of Deeds. The only exception is if your amendment changes how a specific piece of real estate is held -- and that change is reflected in a new deed, not in the trust amendment itself.

What if my trust says amendments require my attorney's signature?

Some Michigan trusts drafted in the 1990s and 2000s contained these unusual provisions. If your trust includes such a requirement, you must "substantially comply" with it -- which usually means tracking down the original attorney or someone authorized to act on their behalf. If the attorney is deceased or retired, an attorney letter explaining that fact may suffice, but the safest path is to do a restatement that includes a new, simpler amendment procedure.

How many amendments can I have before I should restate?

Two is fine. Three is the gray zone. Four or more should always be restated. Stacked amendments create confusion and invite challenges. A clean restatement provides one document that controls.

Does amending the trust trigger any tax consequences?

For a revocable trust during your lifetime: no. Because you can revoke the trust, the IRS treats trust assets as still yours, and amendments do not affect that. Beneficiary changes do not trigger gift tax because the beneficiaries do not have a current right to anything. After your death, the trust becomes irrevocable and amendments are no longer possible.

What if I want to revoke the trust entirely?

Use the same procedure as an amendment but draft a "Revocation" instead. Reference the trust by name and date, state your intent to revoke entirely under MCL 700.7602, sign and notarize. You then need to retitle any assets out of the trust's name back into your individual name (or into a new trust if you are replacing it).

Can my successor trustee challenge an amendment after I die?

They can try, but Michigan has a short statute of limitations under MCL 700.7604 -- two years from the settlor's death, or six months if the trustee sends formal notice complying with the statute. Per the Siddell case discussed above, properly-notarized amendments with clear language are virtually unchallengeable.

Should I tell the beneficiaries about the amendment?

Not legally required during your lifetime for a revocable trust. After your death, MCL 700.7813 requires the trustee to provide certain information to beneficiaries within 63 days of the trustee's acceptance of office, which includes copies of the trust and amendments. During your life, telling or not telling is your choice.

What if my original trust is missing -- can I still amend?

You need to locate or reconstruct the original first. A trust amendment that references a missing trust creates significant administrative headaches. If the original trust truly cannot be found, the better path is a full restatement that essentially creates a new trust (in the original trust's name and date) and supersedes the missing original.
