What is an abandonment affidavit for adoption in Wisconsin?

An abandonment affidavit is a sworn, notarized document that details the biological parent's lack of contact with the child. It is the key document when proceeding without the other parent's consent in Wisconsin.

What the affidavit includes:

• The date of last known contact between the biological parent and the child
• A description of the parent's absence (no visits, no calls, no communication)
• The duration of the absence (must be 12+ months under Wis. Stat. § 48.415)
• Whether the parent has provided financial support (relevant but not determinative)
• Any efforts you or your spouse have made to facilitate contact
• Your spouse's testimony about the biological parent's involvement (or lack thereof)

Who signs it:

• Your spouse (the child's custodial biological parent) signs the affidavit
• It must be notarized (sworn under penalty of perjury)
• You may also sign a supporting affidavit

Why it matters:

• This is the document the Circuit Court relies on to find abandonment
• It must be detailed, specific, and honest — vague statements are less effective
• We prepare this document with proper legal language that meets Wisconsin's requirements
