Subject: Public records request: delinquent property tax list, Marquette County, Wisconsin

Dear Records Custodian:

Under the Wisconsin Public Records Law, I request a copy of the current list of real property accounts with delinquent property taxes in Marquette County, Wisconsin.

Please include these fields, to the extent your office keeps them:
- Parcel or account number
- Owner name
- Property (situs) address
- Owner mailing address
- Tax years that are delinquent
- Amount owed (by year, if your office keeps it that way)

I would like the list in electronic form (CSV or Excel), sent by email to [Your email]. A file your office already produces is fine. I am not asking you to create a new record.

If there is a charge, please send me an itemized estimate first if it will be more than $25.

If the list will not be ready within 10 business days, please let me know when I can expect it.

If you withhold any part of the list, please tell me which exemption applies and send the rest.

Thank you for your help.

Sincerely,

[Your name]
[Your mailing address]
[Your email]

How to send it

  1. Check what Marquette County already posts. Many tax offices publish the delinquent list on their website or in a newspaper notice before a tax sale. If it is posted, you may not need a request at all.
  2. Find the records contact. Look on the tax office's website for an open-records email address or online request portal. If the office has its own form, you can paste this letter into it.
  3. Send the letter and keep a copy. Note the date you sent it. In Wisconsin, the office has 10 business days to respond, and a response can be the file, a date it will be ready, or a cost estimate.
  4. Approve or question the estimate. Large data pulls can carry a fee for staff or computer time. Ask what it covers before you pay.
