Wisconsin state law dictates that an estate should be closed within 18 months after it is opened. Many counties strive to close out probate cases in a shorter time, typically twelve months. However, the most complex estates may take more than two years to close, and the most straightforward might be wrapped up in six months. The length of the process depends on the size of the estate, the complexity of estate assets, tax issues, creditor claims, whether there is a will contest, and more. An experienced Wisconsin probate attorney can help the probate process move as efficiently as possible.
