How to File Affidavit of Heirship in Wisconsin

When someone dies without a will in Wisconsin, their family often needs to prove who the legal heirs are. One way to do that is by filing an affidavit of heirship. This document helps establish ownership of real estate or personal property when probate isn’t required. It’s commonly used when a house or land was owned by the deceased and there’s no formal estate process.

What exactly is an affidavit of heirship in Wisconsin?

An affidavit of heirship is a sworn statement that identifies the people legally entitled to inherit property after someone passes away. In Wisconsin, it's not a court order, but it can be used in deeds to transfer title, especially for real estate. The person signing it (the affiant) must know the facts firsthand usually a relative or someone close to the decedent.

For example, if your aunt died and left her home to her children, you might file an affidavit to transfer the deed into the names of her surviving children. That’s one common use case.

When should you file an affidavit of heirship in Wisconsin?

You typically file this document when:

The deceased didn’t leave a will
The estate is small and doesn’t need full probate
You’re transferring real property like a house or land
There’s no dispute over who the heirs are

If there’s any question about who inherits, or if the estate includes significant assets, probate may still be needed instead.

Who can sign an affidavit of heirship in Wisconsin?

Only someone with direct knowledge of the family relationships and death can sign. That usually means a close relative like a child, sibling, or spouse. The signer must swear under penalty of perjury that the information is true.

It’s important: the person signing cannot be a beneficiary unless they have independent evidence. For instance, if you’re named as an heir, you can still sign but you’ll need other witnesses to verify the facts.

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

You’ll need several key pieces of proof:

A certified copy of the death certificate
Proof of relationship (birth certificates, marriage certificates)
Any existing deeds or property records
Witness statements from two people who know the family history

These documents help confirm the heirship details and make the affidavit valid. Missing even one piece can delay the process.

How do you actually file the affidavit in Wisconsin?

Start by filling out the official form. Wisconsin doesn’t have a single statewide form, but most counties accept a standard affidavit template. You’ll list the deceased’s name, date of death, known heirs, and how each heir is related.

After completing the form:

Sign it in front of a notary public
Have two disinterested witnesses also sign and notarize their statements
File the signed affidavit with the county recorder’s office where the property is located

Once filed, the document becomes part of the public record. It can then be used to update property titles or sell the inherited land.

Common mistakes to avoid

Even small errors can cause delays or rejection. Watch out for:

Incorrect dates or missing names
Not having witnesses sign in front of a notary
Using outdated or incorrect forms
Trying to file without proper documentation

One mistake people make is assuming the affidavit alone transfers property. It doesn’t it just supports the transfer. You’ll still need to record a new deed with the county.

What happens after you file?

After filing, the affidavit becomes part of the public record. If you're updating a property deed, you’ll need to work with a title company or attorney to prepare the new deed using the affidavit as supporting evidence.

Some lenders or title insurers may ask for additional proof, so keep copies of everything. Also, remember that an affidavit of heirship does not replace probate if the estate is large or contested.

Is there a fee to file an affidavit of heirship in Wisconsin?

Yes. Most counties charge a filing fee typically between $10 and $50, depending on the location. Some places also charge extra for recording a deed afterward. Check with your local county recorder’s office for exact fees.

Final tips before you begin

Take your time. Family histories can be complicated, and small errors can lead to longer delays. Make sure all documents match names spelled the same way, dates consistent. Double-check that both witnesses are truly independent (not beneficiaries).

If you're unsure, talk to a local attorney or contact your county clerk’s office. They can answer specific questions about forms and procedures.
