When someone dies without a will in Wisconsin, their property doesn’t automatically go to the people they might have wanted it to. Instead, the state uses legal processes to determine who inherits. One of those tools is an affidavit of heirship. Filing this document helps prove who the legal heirs are, especially when there’s no probate estate. It’s often used to transfer real estate or clear title on property.

What exactly is an affidavit of heirship in Wisconsin?

An affidavit of heirship is a sworn statement that identifies the deceased person’s family members and confirms who legally inherits their assets. It’s not a will, but it serves a similar purpose when there's no estate plan. In Wisconsin, this document is most commonly used to transfer ownership of land or a home when no formal probate process was started.

For example, if your parent passed away and left a house to you and your siblings, but didn’t leave a will, you can file an affidavit of heirship to officially claim ownership. The county recorder’s office will accept it as proof of inheritance, allowing you to update the deed.

When do you need to file an affidavit of heirship in Wisconsin?

You’ll want to file one if you’re trying to sell, refinance, or transfer real property after a relative passes away and there’s no will. It’s also common when the estate is small and probate isn’t necessary.

Keep in mind: this only works for certain types of property mostly real estate. If there are significant debts, multiple beneficiaries, or complex assets, probate may still be required instead.

Who can sign an affidavit of heirship in Wisconsin?

The person filing the affidavit must be someone with firsthand knowledge of the family relationships. This is usually a close relative like a child, sibling, or spouse who can swear under oath that they know who the legal heirs are.

You’ll need to provide your full name, address, and relationship to the deceased. You’ll also have to list all other heirs and explain how you know they’re related. The notary will verify your identity and witness your signature.

What documents do you need to prepare?

Before filling out the form, gather key records like the death certificate, birth certificates of the deceased and heirs, marriage certificates (if applicable), and any prior deeds or property records. These help confirm family ties and ownership history.

How do you actually file the affidavit in Wisconsin?

Start by completing the affidavit form. Make sure every section is filled out clearly and accurately. Then, take it to a notary public. The notary will ask you to sign it in their presence and affix their seal. This step is critical without a proper notarization, the document won’t be accepted.

After that, you’ll submit the notarized affidavit to the county clerk’s office where the property is located. Most counties require you to file it with the official records for real estate transfers. You may also need to pay a small filing fee.

Check the specific steps for your county at how to submit the document properly.

Common mistakes to avoid

• Using outdated or incorrect names (e.g., using a former married name without explanation).
• Forgetting to include all heirs even distant relatives could have a claim.
• Failing to get the document notarized before submitting it.
• Submitting the affidavit without a certified copy of the death certificate.

One mistake that trips up many people: assuming the affidavit alone is enough to transfer a deed. In most cases, you’ll still need to record a new deed with the county, using the affidavit as supporting evidence.

Do you need help with the notarization process?

Notarizing the affidavit is straightforward, but it’s easy to make errors if you're not familiar with the rules. A notary will check your ID, watch you sign, and stamp the document. Some notaries may ask for extra proof of your relationship to the deceased.

Next steps after filing

Once the affidavit is filed, keep copies of everything your signed form, notary stamp, receipt, and any correspondence. You’ll likely need these later when applying for a new deed or working with a lender.

If you’re transferring property, contact the county land records office to start the deed change. They may ask for a certified copy of the filed affidavit.

For more details on the forms you’ll need, review which forms are required. Always double-check with your local government office, since procedures can vary slightly between counties.
