NFL star Adrian Peterson never skimped on child support to the mother of his 2nd child, not once -- despite her claims -- at least according to official documents obtained by TMZ.
As we reported ... Erica Syion filed court docs back in April, accusing AP of stiffing her on more than $50,000 in unpaid child support and other bills (including travel expenses and tuition) related to their 4-year-old son.
She told us, Adrian eventually settled with her in September, paying all his outstanding bills -- but we've obtained official docs showing child support was NEVER in arrears.
According to the papers, Adrian has dutifully paid his child support to Erica ($2,500 a month) since 2009.
Sources close to AP tell us the court order which determined child support ... did NOT require him to pay tuition and travel expenses -- however when Erica raised the issue, Adrian ponied up.
We've also obtained docs showing Adrian asked the court for more visitation time with his son.
We reached out to Erica, but she hasn't gotten back to us.
