You can only claim a child on your taxes if you provide at least 50% of the FINANCIAL support (through mortgage, food, clothing, education, etc.) for the child. If you provided at least 50% of the support for the child, then you can claim the child for the tax year in which you provided the support.
Keep the claim active with child support enforcement
Because the state provides most of the support for an incarcerated child, a taxpayer may not claim a child if the taxpayer provides less than one half of the child's support.
Contact Child Support Enforcement every 24 months.

I can't find any evidence that he ever had a child out of wedlock.
The length of time for someone to claim child support can vary depending on the jurisdiction. Generally, the custodial parent can claim child support until the child reaches the age of majority, which is typically 18 years old. Some jurisdictions may allow for an extension of child support if the child is pursuing higher education.
The person who provided physical custody of the child for more than 50% of the year can claim the child as a dependent, regardless of whether or not back child support is owed.
To claim a child as a dependent on your taxes, the child must have lived with you and you must have provided support for over 50% of the year. So the mother in this case can claim her grandson on her taxes if she supported the child for at least 183 days out of the year, regardless of whether or not the mother of the child owes back child support.
