Let's take a hypothetical case: A couple divorces when their child is three years old. Mom has custody, and Dad moves out of state. For the first few years, Dad sees the child regularly, but now he has remarried and his visits are infrequent. He is now happy and actively participating in the raising of his two new children.

He wishes to reduce support to his first child because he feels resentful about providing for a child he has no relationship with and money is tight in his new household. Do you think he should be permitted to do this? What do you base your opinion on? Does your answer change if Mom has interfered with his visits without good reason? Does your answer change if Mom left him because he was abusive? Should these kinds of issues influence support determinations?
