You have to go to tapu office and sell the share you are giving her to her name. No actual money has to change hands,obviously, but tax will be due on the value you sell, 4% I believe. You will by law need a translator at time of sale. You will need all photos and documents for a purchase/sale. Usual costs on a sale purchase will be due. You can use a registered translator to do everything. Total cost will vary according to value council places on your property.
