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 other assets when probate isn’t required. It’s commonly used for transferring property titles, especially when there’s no formal estate administration.

What exactly is an affidavit of heirship?

An affidavit of heirship is a sworn statement that lists the deceased person’s relatives and confirms who inherits their property. It’s not a will, but it serves as official proof of family relationships and inheritance rights. In Wisconsin, this form is usually filed with the county recorder’s office to update property deeds.

When should you file an affidavit of heirship in Wisconsin?

You might need to file one if a loved one passed away and left real estate behind, but didn’t have a will. It’s most common when the estate is small, or when there are no disputes among family members. For example, if a parent died and left a house to their children, and all children agree on who gets what, an affidavit can help transfer the deed without going through probate.

If you're unsure whether your situation qualifies, review the specific requirements for affidavits in Wisconsin. The process doesn’t apply to all estates especially those with complex debts or contested claims.

Who can sign an affidavit of heirship?

The person completing the affidavit must be someone with firsthand knowledge of the deceased’s family ties. That could be a close relative, such as a child, sibling, or spouse. They must swear under oath that the information they provide is true and accurate. In some cases, a notary public will witness the signing.

It’s important that the person signing has lived with or closely known the deceased. If someone only knows about the family through hearsay or secondhand stories, they may not be eligible to sign.

What documents do you need to prepare?

You’ll need several pieces of supporting evidence. These include death certificates, birth certificates, marriage certificates, and any records showing family relationships. A certified copy of the death certificate is essential it’s typically required by the county recorder.

How do you actually file the affidavit?

Start by filling out the affidavit form. Make sure every section is complete and matches the facts in your supporting documents. Then, take it to a notary public for signing. After that, file the original with the county recorder’s office where the property is located.

Some counties accept digital copies, but it’s safer to bring the original. You may also need to pay a small recording fee typically between $10 and $50, depending on the county.

Common mistakes to avoid

  • Using outdated or incorrect names (e.g., using a married name instead of a legal name at death).
  • Missing a required signature from a notary or witness.
  • Filing in the wrong county always confirm where the property is located.
  • Trying to use an affidavit for large estates or properties with liens.

One mistake people make is assuming an affidavit works for any type of property. If the deceased had a mortgage or unpaid taxes on the home, the title can’t be transferred this way. Always check with the county recorder before starting.

What happens after you file?

Once the affidavit is recorded, it becomes part of the public record. This helps clear the title so the heirs can sell, refinance, or transfer the property. It’s a permanent document, so accuracy matters.

If another heir later challenges the claim, the affidavit can be used as evidence in court but it’s best to avoid disputes by getting everyone involved to agree upfront.

Next steps: Start with the right paperwork
