relative to the allocation of parental rights and responsibilities and establishing a presumption of equal parenting time.

HB 1770 establishes a legal presumption of equal parenting time (50% of overnights annually) for New Hampshire family courts, replacing the current "best interest" standard. It defines equal parenting as a 50/50 overnight split with no more than a three-night difference in any year, requiring courts to correct imbalances the following year. The presumption can only be overridden by clear and convincing evidence of specific harm - such as abuse, neglect, domestic violence, or a parent's incapacity - and courts must provide written findings for any deviation. This applies to all custody cases, including initial rulings, temporary orders, and modifications, and takes effect January 1, 2027.
