In Wisconsin, if the estate (all of the property that does not automatically transer by itself) is over $50,000, you will need to open a probate case to get Domiciliary Letters, which will appoint you as the Personal Representative. You will then have the legal authority to handle all of your late father's assets and property.
If the estate is under $50,000, the process is much easier. You can fill out a Transfer by Affidavit form that will give you the same authority without court involvement.
In either case, the forms needed can be obtained from the probate court in the county where your father passed. The probate forms are also available online here, though you may want to talk with someone at the court or a lawyer before you go digging through the forms online, as there are a lot of them and they are not self-explanatory.
