What does this mean?

I was going to sign my son up for kindergarten next year (I’m homeschooling him for pre-k this year) and it asks for this:

5. Present a Baptismal Certificate for every Catholic student.

6. File a custody statement with the school office for students of separated/divorced families.

My sons father isn’t and has never been in the picture. Not on the birth certificate. So, is that irrelevant to me? Or does that mean he can’t go to this school?
