If the house that you live in is owned by both parents (or rented by both parents) then you cannot force the other parent to leave the house without either a Family Court Order for sole occupancy of the house or an Ouster Order being attached to a Domestic Violence Order (an Ouster Order is an Order for the other person to vacate the property within a certain timeframe).
If you rent the property and the rental agreement is in your sole name or the property is in your sole name then you can refuse the other parent entry to the property. The only way they could then be technically permitted access to the property would be if they obtained either an Ouster Order or Sole Occupancy Order from the Court.
