I'll try to make it as brief as possible. Grandma dies in September. She was a cosigner on my sister/brother in law's home years ago. My grandma's estate was just settled and closed today via probate according to her attorneys. My sister/bil that own the home are now seperated and will divorce. They are going to allow the property to go into foreclosure. Could grandma's estate still be held liable for this property that goes into foreclosure? My aunt says yes, but it seems to me that if the probate closed the case on this, it should be over with right?

It depends on the probate process - creditors are allowed to make claims against the estate and they must generally be paid prior to the distribution of assets to the beneficiaires. http://resources.lawinfo.com/Search....e%2C+creditors.
