This question is more complex than it seems. In its simplest form, you are not required to take any action. When you sell the property at some point in the future, indicate on the deed, for example, "Mary Smith, nka (now known as) Mary Jones hereby grants, etc."
There are many other details that affect the answer to this question. The most important of which is Wisconsin's Marital Property law. This law assumes that property used by a couple during the course of a marriage is jointly owned unless specified otherwise.
If you wish to remain the sole owner of the property and do not intend to convey any interest in the property to your spouse, steps must be taken prior to and during the marriage to ensure this occurs.
However, if you intend for your spouse to share in the ownership of the property, there are a number of ways a married couple can hold title to the property. Each one has distinct legal implications. Depending on your financial status, age and other factors, a trust might even be advisable.
As you can see, it is best to seek the help of an attorney to draft a deed that will accomplish your goals.
