@Mike9241 - it wasn't clear who is paying for than 50%; while housing and food was discussed (and they are normally the largest), it never discussed utilities, transportation, medical, etc. etc. etc.
Certainly, the grandmother and mother have to determine which one of them is paying more than 50% as it is a critical determinate of who can be HOH, which is why i stated it could be Grandma.
I find these dependent questions can be very complex and dependent on variables that are often not posted, so I normally just point the question to the IRS tool - it is the source of the Truth.
