Probate is triggered when solely-titled probate assets exceed $50,000 or when the decedent owned real estate not held in a trust, joint tenancy, marital property with right of survivorship, or under a TOD designation. Wisconsin's informal administration (supervised by the county Probate Registrar) handles most uncontested estates without judicial hearings.
Informal administration (the most common Wisconsin path) typically closes in 6-12 months. Formal administration can run 12-18 months. Wisconsin law generally expects estates to be closed within 18 months of death.
Wisconsin's Transfer by Affidavit allows qualifying estates to skip formal probate.
| If the death occurred… | Small estate threshold |
|---|---|
| Current threshold under Wis. Stat. § 867.03 (raised from $20,000 effective 2014) | $50,000 |
| Prior threshold pre-2014 | $20,000 |
Under Wis. Stat. § 867.03, when the entire probate estate is $50,000 or less, an heir can transfer property using a Transfer by Affidavit 30 days after death. Real property is excluded and must pass through probate or another transfer mechanism.
Under Wis. Stat. § 857.05, the personal representative is entitled to a commission of 2% of the inventory value of the estate, or a rate agreed in writing. The court may allow more in cases of unusual difficulty or extraordinary services.
Example: An estate valued at $1,000,000 would yield an executor commission of approximately $20,000.
Attorney fees:
Attorney fees are reasonable and separately reviewed. Wisconsin allows the personal representative to be paid either the commission or attorney fees, but not both, unless the will authorizes both.
Multiple co-executors:
Co-personal representatives share a single 2% commission; the court allocates among them based on services rendered.
Statute: Wis. Stat. § 857.05
Bond is required by default in informal administration, particularly when there is no will. A will can waive bond, and pro se personal representatives generally must file a surety bond.
Statute: Wis. Stat. § 856.25
Wisconsin has no state estate tax (it was repealed for decedents dying after December 31, 2007). Only the federal estate tax applies, and after the One Big Beautiful Bill Act, only estates above $15 million per individual ($30 million per married couple) in 2026 owe federal estate tax.
Wisconsin is a marital property state (its version of community property) under Wis. Stat. Ch. 766. Each spouse owns an undivided one-half interest in all marital property acquired during marriage. At death, the surviving spouse already owns half of marital property; the decedent can only dispose of his or her half. Wisconsin also provides a deferred marital property elective share under Wis. Stat. § 861.02.
Wisconsin operates one of the more aggressive Medicaid Estate Recovery programs in the country. The state recovers from probate AND non-probate assets — including marital property, joint property, and life estates — of recipients age 55+ who received long-term care. Recovery is deferred while a surviving spouse, minor, or disabled child lives in the home.
The full Wisconsin executor checklist has 24 milestones: 0 specific to Wisconsin law (shown below — filings, forms, and court interactions tied to Wisconsin statutes) and 24 universal duties that apply in every state (expandable at the end of the list). The same item never appears in both groups.
Obtain certified death certificates
Order at least 10-12 certified copies of the death certificate from the Wisconsin Department of Health Services, Division of Public Health, Vital Records. These are required by the circuit court, financial institutions, insurance companies, and government agencies.
Locate and review the will
Search for the decedent's original will and any codicils. Wisconsin follows its own probate code under Wisconsin Statutes Chapters 851-882. Wisconsin is a community property state (having adopted the Uniform Marital Property Act), so distinguishing between marital property (community property) and individual property (separate property) is essential.
Secure estate property and valuables
Immediately secure the decedent's residence by changing locks if necessary. Safeguard valuables such as jewelry, cash, important documents, firearms, and collectibles. If the home will be vacant, arrange for regular checks, maintain climate control, and notify the homeowner's insurance carrier of the vacancy. Secure vehicles, safe deposit boxes, and storage units. Document the condition of all property with photographs.
Determine administration type and file petition
Wisconsin offers formal administration (standard court-supervised process), informal administration (simplified procedure for smaller, straightforward estates under Wis. Stat. Section 867.01), summary settlement (see the small-estate threshold above for current limits), and transfer by affidavit (for personal property (see the small-estate threshold above)). File the appropriate petition with the circuit court (probate branch) in the county where the decedent resided.
Receive Letters Testamentary or Domiciliary Letters
After the court appoints the personal representative, Letters (called Domiciliary Letters in Wisconsin) are issued. The representative must take an oath and post a bond unless waived. Obtain multiple certified copies.
Notify the Social Security Administration
Report the death to the Social Security Administration at 1-800-772-1213 if the funeral home has not already done so. Benefits received after the date of death must be returned. Surviving spouses and dependent children may be eligible for survivor benefits.
Cancel services, subscriptions, and forward mail
Forward the decedent's mail through USPS to the executor's address or a secure location to capture bills, tax documents, and creditor correspondence. Cancel or transfer utilities (electric, gas, water, internet, phone), streaming services, gym memberships, magazine subscriptions, and other recurring payments. Notify the landlord if the decedent rented. Cancel the decedent's driver's license, voter registration, and passport to help prevent identity theft.
Publish notice to creditors
Publish a Notice to Creditors in the official newspaper of the county for three successive weeks, as required by Wis. Stat. Section 859.07. Creditors have three months from the date of the published notice to file their claims. Also mail notice to all known creditors.
Notify financial institutions
Send certified copies of the death certificate and Letters to all banks, brokerage firms, insurance companies, and retirement account custodians. Request date-of-death valuations. As a community property (marital property) state, carefully identify which assets are marital property versus individual property.
Open an estate bank account
Obtain an EIN from the IRS via Form SS-4 and open a checking account in the name of the estate. All estate income and expense payments should flow through this account.
File IRS Form 56 (Notice of Fiduciary Relationship)
File IRS Form 56 to notify the IRS that you are acting as the fiduciary (executor or administrator) for the decedent's estate. This establishes your authority to receive the decedent's tax information, file returns on their behalf, and correspond with the IRS regarding estate matters. File this form promptly after receiving Letters.
Maintain insurance and pay ongoing estate expenses
Review and maintain all insurance policies on estate property, including homeowner's insurance, auto insurance, and any umbrella liability coverage. Lapsed coverage during administration can expose the estate to significant liability. Continue paying ongoing obligations from the estate bank account: mortgage or rent, property taxes, HOA fees, storage unit fees, and essential maintenance. Keep detailed records of all payments for the final accounting.
File inventory of estate assets
Prepare and file an inventory of all estate assets with the court within six months of appointment, as required by Wis. Stat. Section 858.01. The inventory must include all real and personal property with date-of-death fair market values. The court may appoint appraisers.
Handle digital assets and online accounts
Identify and secure the decedent's digital assets, including email accounts, social media profiles, cloud storage, cryptocurrency wallets, online banking, and digital subscriptions. Most states have adopted the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), which governs fiduciary access to digital accounts. Check the decedent's devices, password managers, and records for account credentials. Contact service providers to memorialize or close accounts as appropriate.
File claims against life insurance and benefits policies
File claims on all life insurance policies, accidental death policies, and any other insurance or death benefits payable to the estate or named beneficiaries. Provide certified death certificates and completed claim forms to each insurance carrier. Note that policies with named beneficiaries generally pass outside of probate directly to the beneficiary, but proceeds payable to the estate must be inventoried.
File final personal income tax return (Form 1040 and Wisconsin Form 1)
File the decedent's final federal income tax return (Form 1040) and Wisconsin individual income tax return (Form 1) for the period from January 1 through the date of death. Wisconsin imposes a graduated income tax. A surviving spouse may file jointly.
File estate income tax return (Form 1041 and Wisconsin Form 2) if applicable
If the estate earns more than $600 in gross income during administration, file federal Form 1041 and Wisconsin Fiduciary Income Tax Return (Form 2). The estate is a separate taxpayer.
File estate tax return (Form 706) if applicable
If the gross estate exceeds the federal estate tax exemption, file federal Form 706 within nine months of death. Wisconsin does not impose a separate state estate or inheritance tax. Form 706 may be filed for portability.
Review and pay valid creditor claims
Evaluate all claims filed within the three-month claims period. Pay valid claims from estate funds in the order of priority established by Wis. Stat. Section 859.25: costs of administration, funeral expenses, expenses of last illness, debts with federal preference, taxes, and all other claims.
Distribute specific bequests
Distribute any specific gifts or bequests identified in the will, such as jewelry, heirlooms, specific dollar amounts, or particular assets to named beneficiaries. Obtain signed receipts from each beneficiary. Ensure adequate reserves are maintained for taxes, administration costs, and any pending creditor claims before making distributions.
Distribute residuary estate to beneficiaries
After all debts, taxes, expenses, and specific bequests have been satisfied, distribute the remaining estate assets to the residuary beneficiaries as directed by the will or Wisconsin intestacy law (Wis. Stat. Section 852.01). The surviving spouse's marital property interest is protected. Wisconsin also provides a statutory allowance for the surviving spouse and minor children. Obtain signed receipts from all beneficiaries.
File final accounting with the court
File a final account with the circuit court detailing all receipts, disbursements, and distributions, as required by Wis. Stat. Section 862.05. The court will review and approve the accounting. Under informal administration, the personal representative provides an accounting to interested persons rather than filing with the court.
Obtain judgment of final settlement and close the estate
After the court approves the final accounting, a judgment of final settlement is entered. The personal representative is discharged and the estate is closed. Close the estate bank account and retain financial records for at least five years.
Close the estate bank account
After all distributions are complete and the final accounting is approved, close the estate bank account. Ensure all outstanding checks have cleared and no further transactions are pending. Retain all financial records for at least seven years for tax and audit purposes.
If the decedent owned Wisconsin real estate but was domiciled elsewhere, ancillary probate is required in the Wisconsin Circuit Court for the county where the property is located. An authenticated copy of the foreign will and probate order is required.
Informal administration (the most common path) typically closes in 6-12 months. Formal administration may run 12-18 months. Wisconsin law generally expects estates to be closed within 18 months of death.
The filing fee is 0.2% of the value of property subject to administration (e.g., $2,000 on a $1M estate), with a $20 minimum. Statutory commission is 2% to the personal representative. Attorney fees for uncontested informal administration commonly run $2,500-$5,000.
Wisconsin's Transfer by Affidavit (Wis. Stat. § 867.03) is available when the entire probate estate is $50,000 or less. The affidavit may be used 30 days after death. Real property is excluded.
Wisconsin allows informal administration without an attorney, supervised by the Probate Registrar. Formal administration requires a licensed attorney. Pro se personal representatives must also typically file a surety bond.
Yes. Common tools include revocable living trusts, joint tenancy with right of survivorship, marital property with right of survivorship, Transfer on Death deeds (Wis. Stat. § 705.15), POD/TOD accounts, and beneficiary designations.
Under Wis. Stat. § 856.05, the custodian of a will must file it (or deliver it to the named personal representative) within 30 days of learning of the death. A named personal representative who has the will must file it with the court within 30 days.
No. Wisconsin repealed its state estate tax for decedents dying after December 31, 2007. Only the federal estate tax applies, and for 2026 the exemption is $15 million per individual / $30 million per married couple under the One Big Beautiful Bill Act.
Yes. Wisconsin has authorized TOD deeds (technically 'TOD beneficiary designations' on a deed) under Wis. Stat. § 705.15. A properly recorded TOD designation lets real estate pass outside probate to the named beneficiary.
