Postponement for the father of 3 minor children

I am the father of 3 minor children, two children were born in marriage, one child is out of wedlock on the birth certificate, I am the father, with the mother of the child we have drawn up a notarized alimony agreement, where I transfer funds for maintenance every month, and the child lives with the mother, or are there enough grounds for receiving a deferment in connection with the maintenance of 3 minor children?
