hi good day, i have some questions on the property ownership transfer procedure. In my case, my parents had a house which is under both me & my sister's name. Recently, my parents decided to buy a new house to put under my sister's name, and the current house transfer to my name. But after contacted the lawyer via phone, he told us that this direct property ownership transfer for this current house cannot be done, unless the current house installment is fully paid or we sell the house. The lawyer ask us to arrange an appointment with him for more details.

need some guidance and advice from professions here, is that really we cannot direct transfer the property ownership?
my thanks in advance
