No!! Not unless it's court ordered.
As a married father do I have the right to prevent my wife from taking our son to go see his grandmother at her house?
Nope!
Sorry you don’t like grandmother but you loose this one.
Why do you want to?
Do you believe the child is endangered by the visit? If that is the case, you should talk to your wife. If she doesn't listen to your concerns, you have bigger problems. And you will need to get a court order to prevent the visit.
If it's just because you don't like the grandmother ... Learn to live with it.
Trouble between spouses?
