How do I legally remove my uncles and his girlfriends personal property from my Grandmothers house that he has left behind.

I don't practice in Illinois, but the basic procedure should be the same. First, if he ever had any kind of lease -- verbal or written -- and you have not done so, you need to evict him. At the end of that process you'll have a writ of possession and the sheriff will move all his stuff out.

If he never had a possessory right to be in your property you need to provide adequate notice. I suggest calling a storage place and asking them what kind of notice they give when they get rid of an occupant's stuff for failure to pay the rent.
