[Ilaw] Custody modification

Good morning. Client and ex are modifying their custody agreement from their divorce. Currently, there is no Court proceeding pending, either Family or Supreme. If the parties execute a modification agreement does a proceeding need to be filed in Family Court/Supreme Court or can the agreement just be filed in Supreme? Thank you. Jody N. Gerber, Esq. 450 Seventh Avenue, Suite 2710 NY, NY 10123 (212) 683-6634
