This will involve a lot of work on your end, unless you can easily see that the nursing home/Medicaid has paid for more than half his expenses. Basically, it's who paid more than half his expenses during the year and do you have the receipts to prove it if by chance you are audited. You can get into the nitty gritty like his portion of the housing/utilities/food, etc. But really unless you kept track beginning last Jan, you are looking at a lot of work now. Good luck.
