The parenting agreement can be terminated at any time.
If both parties agree a modification is neccessary, it's a matter of submitting affidavits for the judge to decide the terms set forth warrant a change that will be in the child's best interest.
If both parties do not agree, the matter will be brought forth for hearing for the judge to decide the child's best interest up to and including interviewing the child as to the child's wish of whom to have custody in their best interest. (which is where we were at when I "threw in the towel" to avoid).
