Is there an Oregon law stating only natural parents may be called father or mother?

Is there an Oregon law stating only natural parents may be called father or mother?
I have heard there is an Oregon Law stating only natural parents may be referred to as “mother” or “father” (or their equivalents) but have been unable to find such a thing in the Oregon Revised Statutes. The only thing I have found is mention of it regularly being in divorce decrees. Has anybody out there heard of an actual law explaining this?

Do you know why you can’t find anything? Because it isn’t a law. As a matter of fact, it’s unenforceable. It doesn’t even make sense. Who would waste anyone’s time worrying about it?
