Judge order name change. Does support stop that day?

Ok, before anyone can give you an answer, you first have to ask a question. Also be sure to tell what state you are in because different areas have different local laws.

A name change, by itself, has nothing to do with support. Only if the name change is a result of an adoption does it affect support. So you really need to give us more info for us to help.

I agree, a name change has no effect on support payments, adoption of child would effect. Perhaps you can tell us more about what is happening.
