The personal representative must be represented by an attorney if formal probate is filed. The Wisconsin Legislature created a procedure for probating a decedent's solely owned property as well as property in which he had a joint tenancy interest in an informal manner without the necessity of processing the probate through the court and without the necessity of an attorney, if certain conditions are met. You may use an attorney, as needed, at any time during informal probate.
At any point in informal administration, you can ask the court to switch from an informal to a formal. The Registrar can also ask the court to switch to a formal, and you would then be required to retain an attorney. The Probate Registrar can answer questions on preparation of forms but cannot give legal advice.
