I am a single woman living in Sioux Falls and want to add my son's name on the title of my home as a joint tenant. What are pros and cons?

In South Dakota, the main advantage of adding your son's name to your house is that doing so will avoid probate and make it easier for him to take possession upon your death. The main disadvantage is that the property will be subject to any claims for your son's debts and could even come into the picture if he were to get divorced.
