I'm married and the development of the house is from the purse of me and my wife

I live outside the country but I entrusted my house development with my parents in Nigeria, but they leave in a rented apartment. They're are due for new rent payment at their rented apartment which i sent them the money, only for them to call me that they don't want to rent another apartment again and have moved into my ongoing house and used the money to do somethings in the ongoinghouse. What do I do?
