This was a question that came up at book club:

Parent 1 claimed child as dependent in odd numbered years

Parent 2 claimed child as dependent in even numbered years

The year the child turned 18 and graduated and child support ended on 18th birthday, both parents claimed child as he became full time college student.

The year was an even year but parent 2 did not provide support other than partial year child support and some college funds.

Which parent was in error claiming the child? No one had the answer. I suggested a tax preparer be consulted.
