If a father is not on the birth certificate, does his parents have rights to get grandparents…

Yes

Not automatically. Paternity needs to be established. They can’t prove they are the grandparents. They would have to go to court and have a DNA test to be able to get their grandparents rights established.

Idaho is a state where grandparents have rights, but they’d have to establish paternity first. They can legally get a court ordered paternity test. But without establish paternity, they have no rights.

Can they? Yes. There is a process they'll have to follow though. Are you against them having contact for any particular reason?
