Do I put my name on an offer to purchase real estate with my sister that she is paying cash?

Gifts and inheritances are exempt from property division in a divorce under Wisconsin law, when received before or during the marriage from a third party; if you trust your sister that she is buying the property for you and at some point down the road will transfer appropriate title to you, you could ptoceed  by having the property titled in her name; if you proceed by her giving you the money now so you can purchase the property on your own and have it titled in your name, you may find the title company refusing to allow you to close on the property in the middle of a divorce without first providing a copy of your  divorce decree proving you are already divorced or your spouse signing a chapter 766 waiver form relinquishing marital property rights to the home you are purchasing.
