Do I really need help with my mother's probate in South Dakota or can I just do it on my own?

You can certainly do your mother's probate in South Dakota on your own.  However, probate can often be complicated and you should seriously consider hiring a South Dakota probate attorney to make sure the process is done correctly.

Of course, when trying to find a South Dakota probate attorney, you should make sure he/she is licensed in South Dakota and has experience in probate issues.
