When a child is not residing with the custodial parent on a full-time basis, is the child entitled to half of the table amount of support payable to the parent?

The court further stated that once a child becomes an adult, it is appropriate to reduce the table amount of support payable to the custodial parent for the time period when the adult child is not residing with the custodial parent on a full‑time basis. In Lu v. Sun, supra, the court confirmed that one half of the table amount was appropriate in the factual situation presented and in recognition of the "ongoing costs" borne by the mother in maintaining the daughter's permanent home and in covering incidentals that she as the custodial parent must provide [para. 28].
