I agree with you morally. I'd wait for the DNA test before I explained to my 10-year-old that he had a sibling. I'd want to be sure. But it's his call, and he can explain now or wait until later. He has the right to tell his own son about a possible sibling if he wants to. You can't legally prevent it.

I agree that it would be very hard to restrict another parent from informing the child of life events. The only option you may have is file to enjoin him from discussing it with your son pending the findings as it would be in the child's best interest. The courts are always focused on the best interests of a child. Without the court explicitly telling him otherwise, he's able to discuss it with your child but if the information ends up false and harmed your son, he'll have to explain to the court his actions.
I agree with your thought process, but there is also the other side of the coin that allows both parents to be able to co-parent the child. If he feels this is something that would be best then I am sure he will go ahead and tell him. Perhaps having an honest talk with him will help, express your concerns and ask that he wait until proof is received.

I agree with my colleagues. It makes no sense to get him hopped up about some possibility without proof first. Still, I understand why the father feels the need to tell the son (when appropriate). Good luck!
