No. If the decedent had a will, the original will must be filed with the Register in Probate within 30 days of the date of death regardless of whether or not a probate is filed.
If the decedent’s solely owned assets are less than $50,000, you may be able to use the Transfer of Affidavit ($50,000 and under) Form PR-1831, which can also be obtained online from Wisconsin Courts. This form is not filed in the Probate Office.
Generally, if a decedent had more than $50,000 in solely owned assets, a probate is necessary to transfer ownership of the decedent's assets to his/her heirs.
