I am sorry for your loss.
If your assets were truly held as joint "with rights of survivorship", then probate may not be necessary. As an example, if you and your wife were both on the deed to your home (or other real estate), unless the deed says you both own it jointly "with rights of survivorship" then you will have to go through probate (SC law deems it as though you each own a 1/2 interest in the home).
You may also want to go through probate to avoid any creditors that your wife may have had for which you are not responsible.
