Consequences of sales law when selling a home?

Questioner

In 2016, we concluded a mortgage deed with a right of sale to my father. However, we want to sell the house. But I don't know how this sales right works. My father says we can't sell anything without his permission, but from what I read on the internet we only have to offer it to him for the price we can sell it for. If my father says he doesn't agree, we can sell it to our buyer. But what is true?

Lawyer

What is decisive is what is stated exactly in the deed. I advise you to consult this and also to contact the notary.
