Changing a parenting plan: the adequate-cause gate comes first

A motion to modify a parenting plan is DENIED unless the supporting affidavits establish adequate cause for a hearing — only then does the court set a show-cause date. Behind the gate, major changes need a substantial change in circumstances (with the statute's own lanes: agreement, integration, detriment, the limitations conduct), while minor schedule adjustments ride a lighter track. Support modification runs prospectively on its own rules.
