I am pursuing child support from my son's father. Upon being served my son's father has now changed the after school and summer custody arrangement that has been in place for the last 4 years. (which is my son remains with me after school and summer days when his father works) Can he legally do this? 
My son is suffering... ANY advice to my rights to try and keep a sense of routine in my sons life would help. (I know his father is now trying to demonstrate 50/50 custody as with the after school care etc. the custody split was 41% to 59%.) Can he just out of the blue change the schedule like this?
My son is already feeling the ripple effect of not seeing me (or I him) everyday as per usual. (acting out in class and home sick from school before the 1/2 way mark today)
He is 12.
Any help would be appreciated!
Thank you,
