The maternal grandparents applied for custody of their 9-year-old granddaughter following the death of the child's mother.
The father, who had access under a previous court order, also sought custody.
The court found that the child had lived primarily with her maternal grandparents and had a strong attachment to them, and that moving her would cause further trauma.
The court also noted the father's history of alcohol abuse and the high level of conflict between the parties.
Sole custody was awarded to the maternal grandparents, with a specified access schedule for the father, subject to a prohibition on alcohol consumption during access.
The father was also ordered to pay retroactive child support.
