Statutory Authority

Wills

WI Stat., Ch. 853 (§s853.0101, et. seq.).

Trusts

WI Stat., Ch. 701 (§§701.01, et. seq.).

Wisconsin Will Requirements

A Wisconsin Last Will and Testament should include:

  • Age and Capacity: Testator must be at least 18 years old and have adequate mental capacity
  • Format: Must be in writing
  • Signature: Must be signed by the testator (or by another person in the testator’s presence and at his or her direction)
  • Witnesses: Must be signed by at least two witnesses

Witness Requirements

For Wisconsin wills:

  • Witnesses must observe the testator signing the will or hear the testator’s declaration that the testator’s signature is genuine
  • Witnesses must sign the will in the testator’s presence and within a reasonable time after the signature or authentication occurs
  • Anyone competent under Wisconsin law to act as a witness in court can witness a will

Interested Witness Limitations

A Wisconsin will witnessed by an interested party (i.e., someone who receives a personal and beneficial interest under the will) is not invalid as a whole. However, provisions in favor of an interested witness (or an interested witness’s spouse) are void to the extent the value exceeds what the witness would have received had the testator died intestate.

Self-Proved Wills

Though notarization of a will is not strictly required in Wisconsin, a will can be made “self-proved” if it includes a notarized affidavit with a self-proving clause attached to the will. When a will is self-proved:

  • The affidavit is executed by both witnesses and the testator
  • It states that the testator willingly signed the will with the intent to create a will and with the required legal capacity
  • The affidavit serves as evidence of the will’s authenticity and allows for admission in probate without further witness testimony

Incorporation by Reference

Wisconsin law authorizes testators to incorporate other documents within a will by reference:

  • Documents can include written lists setting forth dispositions of tangible personal property not otherwise addressed in a will
  • These “memorandums of personal property” must be signed and dated by the testator
  • The list must identify with reasonable certainty the devised items and intended recipients
  • A list of personal property can be created before or after a will is executed and can be altered by the testator
  • Wisconsin law also authorizes a similar list disposing of “digital property
When a Wisconsin decedent leaves a will, it is presumed to pass his or her entire estate, and distributions are presumed to transfer the entire interest in transferred property.

Amendment, Revision, and Revocation of Wisconsin Wills

Revoking a Wisconsin Will

Wisconsin wills can be revoked by:

  • Physical destruction of the will (e.g., by burning or tearing) with the intent to revoke
  • Execution of a later will or codicil that explicitly declares an intent to revoke the prior will

Amending a Wisconsin Will

Amendment of a Wisconsin will can be accomplished through:

  • A codicil (a later-executed addendum to an existing will)

The codicil must satisfy all formalities required for Wisconsin wills.

Implicit Revocation

A new will that does not expressly revoke a prior will is presumed to revoke the prior will by inconsistency if the later will completely disposes of the testator’s estate. If a later will does not completely dispose of the testator’s estate, it is presumed to have been intended as a supplement to the earlier will, with the later-executed will controlling in the event of any conflicting provisions.

Automatic Revocation by Divorce

If, after executing a Wisconsin will, a testator is divorced, any provisions in the will in favor of the former spouse (or the former spouse’s relatives) are deemed to have been revoked unless the will or a property settlement agreement or other contract between the former spouses expressly states otherwise.

Marriage After Will Execution

If a testator marries after execution of a will, the surviving spouse inherits the same share of the estate he or she would have inherited had the testator died intestate, adjusted for any distributions to children of the testator who are not children of the surviving spouse.

A later-wed spouse’s share is inapplicable if:

  • The will contemplates the marriage
  • Sufficient evidence shows that the testator intended the will to apply notwithstanding the marriage
  • A valid prenuptial agreement is present

Children Born After Will Execution

If a child is born to or adopted by a testator after execution of a Wisconsin will—and if the testator’s will does not provide for or appear to intentionally omit the child—the child inherits a share of the estate:

  • If the testator has no other children, the share is equal to what the child would have inherited had the testator died intestate
  • If the testator has other children provided for under the will, the share is equal to devises to other children

Holographic and Oral Wills

Holographic Wills

Wisconsin law does not recognize holographic (or handwritten) wills. A will written in the testator’s handwriting must satisfy all other requirements for creation of a valid will to be admissible in probate.

Oral Wills

Oral (or “nuncupative”) wills are not recognized under Wisconsin law.

Wisconsin Trust Requirements

Wisconsin trusts are primarily governed by the Wisconsin Trust Code, enacted by the legislature at WI Stat., §§701.0101, et. seq.

Requirements for a Valid Wisconsin Trust

For a trust to be valid under Wisconsin law:

  • The purpose of the trust must be lawful and capable of being achieved
  • In general, the purposes of a trust and the trust itself must be for the benefit of the trust’s beneficiaries
  • The settlor must express an intent to create a trust and have adequate capacity (measured under the same standard applying to wills)
  • Alternatively, a trust may be created by an authorized guardian or conservator
  • A Wisconsin trust is void to the extent its creation was induced through fraud, duress, or undue influence

Required Trust Elements

Wisconsin trusts must have:

  • A definite beneficiary (subject to exceptions such as for charitable trusts, trusts for the care of animals, and certain trusts created for noncharitable purposes)
  • A trustee with actual duties to perform

Sole Trustee/Beneficiary Rule

The sole trustee of a Wisconsin trust cannot also be the trust’s sole beneficiary.

Trustee Responsibilities

Trustees who manage assets are governed by the “prudent investor rule” and must exercise reasonable care, skill, and caution in carrying out their duties.

Trust Creation Methods

Wisconsin trusts can be created through:

  • Transfer of property by a grantor to a trustee (either during life or through a will or other testamentary instrument)
  • A grantor’s declaration that identifiable property is owned as trustee
  • A declaration of the intent to create a trust with the expectation that property will be transferred to the trust
  • By exercising a power of appointment in favor of a trustee
  • Through a court order establishing the trust

Oral Trusts

Though most trusts are evidenced by a written instrument setting forth the trust’s terms, Wisconsin law recognizes oral trusts. However, the creation and terms of an oral trust must be established by clear and convincing evidence.

Revocability

Unless a Wisconsin trust is expressly made irrevocable, the settlor is assumed to retain the power to revoke or amend the trust.

Trust Termination

Wisconsin trusts terminate upon:

  • Revocation or expiration under the trust’s own terms
  • When there is no purpose of the trust remaining to be achieved
  • When the trust’s purposes become unlawful or impossible to achieve

A trust may also be modified or terminated:

  • By a court upon the petition of the settlor, trustee, and/or beneficiaries
  • In some circumstances, upon the consent of the trustee and all beneficiaries
Upon petition, a court may also retroactively reform or modify the terms of a trust for the benefit of a disabled individual to maintain eligibility for public assistance.

Special Considerations

Wisconsin Basic Will

The “Wisconsin Basic Will” is a form published by the Wisconsin legislature (at WI Stat. §853.55). Key features:

  • It is intended as a relatively simple template for creating a will valid under Wisconsin law
  • If completed, executed, and witnessed correctly and in full, a Wisconsin Basic Will is considered valid and admissible in probate
  • As a fill-in-the-blank form, the Basic Will can be useful for testators with relatively small, simple estates with little need for customization
  • The legislature also provides for a “Wisconsin Basic Will with Trust” (at WI Stat. §853.56) that includes a trust for care of children

Estate Taxes

No Estate or Inheritance Taxes

Wisconsin does not impose either estate or inheritance taxes. Large Wisconsin estates may still be liable for federal estate taxes.

Simplified Probate

Small Estate Options

Wisconsin law allows for informal administration of small estates (defined as $50,000 or less) through three methods:

  1. Summary Settlement: Can be used if a decedent leaves a surviving spouse or minor children—or if the estate’s value is not more than specified expenses (e.g., costs of administration, final expenses, etc.) and allowable exemptions
  2. Summary Assignment: Available for some small estates that are not eligible for Summary Settlement
  3. Transfer by Affidavit: Allows an individual to undertake certain responsibilities for the estate and transfer property outside probate under appropriate circumstances

Informal administration is not permitted for estates over $50,000 or intestate estates in which not all interested parties consent to informal administration.

Marital Property

Wisconsin’s Unique System

Wisconsin’s “marital property” system is similar to the “community property” systems used in a few other states:

  • Under Wisconsin’s Marital Property Act, most assets and income acquired by either spouse during a marriage are assumed to belong to both spouses equally, unless they agree otherwise
  • Married Wisconsin residents’ assets often include a significant amount of marital property
  • Married individuals can distribute separate property (e.g., property owned prior to the marriage or obtained via inheritance) and their one-half interest in marital property by will
  • A couple can also agree to own some or all marital property with a right of survivorship, in which case full ownership vests in the surviving spouse upon the other spouse’s death

Non-Probate Transfers

Joint Ownership

  • Assets co-owned as joint tenants with a right of survivorship automatically transfer to a surviving owner upon the other owner’s death
  • Wisconsin does not recognize tenancy by the entireties, but “survivorship marital property” results in a similar outcome for purposes of bypassing probate

Survivorship Marital Property

  • Survivorship marital property (or “marital property with right of survivorship”) is a form of co-ownership Wisconsin allows for spouses
  • Upon one spouse’s death, the surviving spouse acquires undivided title to any survivorship marital property owned by the couple
  • Spouses may also enter into a marital property agreement, which allows for non-probate transfer of property owned by either spouse or both spouses

Beneficiary Designations

  • POD (payable-on-death) designations can be added to financial accounts and CDs
  • TOD (transfer-on-death) designations can be used with assets like registered securities and brokerage accounts
  • Some assets—like retirement accounts and life insurance—allow owners to name a beneficiary who automatically takes ownership of the asset upon the original owner’s death

Transfer-on-Death Instruments

Transfer-on-Death Deeds

Wisconsin recognizes transfer-on-death designations on real estate deeds (commonly called “TOD deeds” or “beneficiary deeds”):

  • The TOD designation is included within a validly recorded deed during life
  • Ownership of the real estate automatically transfers to the named beneficiary upon the owner’s death
  • The beneficiary does not acquire present rights over the real estate until death actually occurs

Vehicle Titles

Wisconsin does not recognize TOD designations on vehicle titles.

Spousal Shares and Protections

Intestate Succession for Spouses

If a married Wisconsin decedent is intestate:

  • The surviving spouse receives the entire estate unless the decedent is survived by children who are not also the children of the surviving spouse
  • If the decedent is survived by children who are not also the children of the surviving spouse, the surviving spouse receives a one-half interest in individual property and one-half of the decedent’s interest in marital property

Deferred Marital Property

Wisconsin also allows surviving spouses to elect a one-half interest in a decedent spouse’s “augmented deferred marital property estate”:

  • Essentially, a surviving spouse can claim up to fifty percent of the portion of a decedent’s estate that did not qualify as marital property
  • The augmented estate includes the decedent’s probate estate, some assets transferred outside probate, and the value of the surviving spouse’s estate that would have qualified as deferred marital property (had the surviving spouse died first)

Wisconsin Spendthrift Trusts

Although the general rule is that creditors of a trust’s beneficiaries may attach a beneficiary’s interest in a trust, Wisconsin law recognizes “spendthrift provisions”:

  • Spendthrift provisions prevent creditors of beneficiaries from attaching trust assets until actually distributed to the relevant beneficiary
  • To be effective, a spendthrift trust’s beneficiaries must be either someone other than the trust’s settlor or disabled
  • Spendthrift provisions do not protect against attachment to satisfy child support obligations

For traditional trusts:

  • Creditors of a revocable trust’s settlor can attach trust assets as long as the settlor remains living (or, upon death, through estate claims)
  • In the case of irrevocable trusts, settlors’ creditors can attach trust assets that could be distributed for the settlor’s benefit (unless the irrevocable trust is for the benefit of a disabled person)

Conclusion

Creating a will or trust does not have to be difficult or intimidating for Wisconsin residents. However, certain circumstances—like second marriages, stepchildren, aging parents, special needs beneficiaries, guardianships, and business interests—can add complexity and result in unforeseen consequences.

Wisconsin offers unique estate planning tools like the statutory Basic Will form for simple estates, marital property provisions similar to community property states, and multiple options for small estate administration. The state’s marital property laws particularly impact estate planning for married couples, making it essential to understand how these provisions affect your assets. When any out-of-the-ordinary issues are present, it’s advisable to consult with an experienced attorney familiar with and licensed under Wisconsin law to ensure your estate plan takes full advantage of the state’s provisions while avoiding potential pitfalls.

FAQs: Wisconsin Wills and Trusts

Q: What are the requirements for a valid will in Wisconsin?

A: A Wisconsin will must be in writing, signed by the testator (or by another at the testator’s direction), and witnessed by at least two competent witnesses who sign in the testator’s presence. The testator must be at least 18 years old and of sound mind.

Q: What is the Wisconsin Basic Will?

A: The Wisconsin Basic Will is a statutory fill-in-the-blank will form (WI Stat. §853.55) provided by the state for simple estates. When properly completed and executed with witnesses, it creates a valid will without needing to draft a custom document.

Q: How does Wisconsin’s marital property system affect estate planning?

A: Wisconsin uses a marital property system similar to community property, where most assets acquired during marriage belong equally to both spouses. This means each spouse can only transfer their half-interest in marital property through their estate plan, while separate property can be distributed freely.

Q: What are my options for avoiding probate in Wisconsin?

A: Wisconsin offers several probate-avoidance tools including living trusts, POD/TOD designations on accounts and deeds, survivorship marital property, joint tenancy, and simplified procedures for estates under $50,000 through Summary Settlement, Summary Assignment, or Transfer by Affidavit.

Q: How are surviving spouses protected under Wisconsin law?

A: Wisconsin protects surviving spouses through intestate succession laws (receiving the entire estate if there are no children from outside the marriage), rights to deferred marital property (allowing claims to property that would have been marital property), and favorable treatment of survivorship marital property.

Q: Does Wisconsin recognize handwritten or oral wills?

A: No, Wisconsin does not recognize holographic (handwritten) or nuncupative (oral) wills. Even handwritten wills must meet all formal requirements including proper execution and witness signatures to be valid in Wisconsin.
