I am in this exact situation but the father of our granddaughter (who did pay some child support in 2019 but is in arrears) is threatening to sue us for fraud if we claim the child. In our case we paid for almost 100% of our daughters plus 2 kids living expenses for 5 months of 2019 which far exceeds what she got in child support (they live in their own apartment). The second grandchild is not his and we claim him already with no complications since his father doesn't do a return. We believe by law we are entitled to claim the second grandchild but are not sure if the 2000 credit is worth the aggravation and possibility of opening ourselves up to an irs audit or lawsuit. Thoughts?
