Beyonce's father is hitting back against accusations he's a deadbeat dad ... he claims he paid what he owes in child support ... it's just a paperwork screw up.
TMZ broke the story ... Mathew Knowles' baby mama Alexsandra Wright says he's behind on 2 months ... to the tune of $24K.
According to sources familiar with the situation, a few of the payments were only slightly late, but past the deadline for being credited, so it appeared Mathew didn't fork over what he owed.
Here's the problem... Mathew is now behind for December -- payment was due on the 1st. We're told he plans to pay up before it officially becomes delinquent.
Think of it as paying your rent, only with a kid.
We've reached out to Wright but haven't heard back.
