What is the relationship between the petitioner and the mother of a child under a consent agreement establishing joint custody?

1. The petitioner-mother is the party with primary physical residence of the child. The parties entered into a consent agreement in August 2011 establishing custody and visitation. The parties agreed to joint custody, with primary physical residence to petitioner. Respondent's basic visitation schedule consisted of three weekends per month, one night during the week (as agreed), and holidays and vacations (as agreed). For the 2015 calendar year, the evidence (particularly, respondent's exhibit A) showed that the child spent about 33.74 percent of all hours with the father, and thus the child spent about 66.26 percent of all hours with the mother. Respondent's exhibit A also showed that the child spent "40.27 % of all days" with the father, but this percentage is skewed because some of the "days" were not overnights. Courts have declined to accord greater weight to the custodial days as compared to the overnight custodial periods (see, Somerville, id. at 880, and Matter of Mitchell v. Mitchell, 134 AD3d 1213, 1215 [3d Dept 2015]). Clearly, the petitioner is the party with primary physical residence of the child.
