Termination of registration as a solo parent

Dear PAO,

My friend, K, is a registered solo parent because she and the father of her child were never married, and the child is under her care and custody. Recently, a social worker visited her to conduct some sort of inspection. It seems that K's neighbor reported that the child has been receiving support from his father. Actually, for the longest time, K's child has not received support from his father. It was only around early this year that the father started providing support for the child's needs. Can that be a basis for the termination of K's registration as a solo parent, even if they are still not married and have no plans of marrying one another?
