Usher's ex-wife, Tameka Raymond nee Foster, has filed emergency legal documents which requests primary custody of their two children be transferred to her. Currently, Usher has primary custody of the children and Raymond has limited rights.

Raymond claims their two children are, when in their father's care, placed in a dangerous environment. This primarily concerns Usher's decision to leave the children in the care of other people, specifically members of his family. Raymond claims those who are in loco parentis are not up to the task of caring for children. 

The filing follows an incident on Monday (5th August) when their son, in Usher's aunt's care, allegedly nearly drowned after his arm became trapped in a pool drain. After being resuscitated, according to E!, the five-year-old was taken to hospital and was "conscious, alert and breathing."

There have been other allegations of the aunt's neglect, made by Raymond, including a claim that she allowed Usher's stalker into the house whilst the children were present. There has also been some implication that the aunt uses physical punishment as a means of discipline her two great nephews.

The documents were filed in Fulton County, Georgia and obtained by TMZ. Raymond's attorney, Angela Kinley, states the filing is because ""the children are at risk while in the care of third-party caregivers...while (Usher) travels around the world for his work-related activities."

The couple married in 2007 but divorced in November 2009. In their short married they had two sons, Usher Raymond V (5) and Naviyd Ely Raymond (4). 

An emergency hearing is scheduled for Friday 9th August.
