ANSWER:

She has no right to stop them from visiting you in your house as this is your house! She can object to them living there but not to visiting you! 

QUESTION: When my parents come to visit me and my children my wife misbehaves with them and fights with me afterwards saying that my parents have no right to come in my house. My parents live in their own house normally. I know that my wife has the right to a separate house in Islam but can she refuse to allow my parents to come to my house for a visit also?
