So I let my Mother, my children's grandparents to claim my children because they did live with her while we remodeled our house. They were able to come back late spring when we got their new bedroom furniture in, which I can show that much. But she claimed them for the whole year this time without asking me because she says she needs the taxes and stimulus money for medical expenses. I only have proof starting when the kids went back to school and dental appointments. What can I do to fight this. She is refusing to change her return.
