MY English teachers always made us rephrase if we asked a question like "Can I ....?" when the question was not one of our ABILITY to do something, but rather of a question of permission or possibility, to which they replied "I don't know, CAN you?"
By this do you mean:
May I attempt to enforce collection measures against the NCP to collect a CS arrearage?
May I agree to accept a lump sum from the NCP in lieu of the entire balance owed?
May I seize certain assets? May I have him jailed for contempt?
May I have some input where I may find the NCP to try to collect?
or
Can I squeeze money out of him even though he's living in a box and muttering about aliens for the past 5 years?
