He finally claimed his newborn daughter, Sailor Grace after months of staying silent.
Now, Dakota Meyer has filed for joint custody and child support, but in order for the case to move forward, Meyer has to take a paternity test.
"It does hurt [to have to prove paternity]," Meyer's grandmother, Jean told the Daily Mail.
"But that's just the way the law is – you have to get permission here and permission there.
"I really think Dakota will do the right thing and I think he has a right to that child."
Though Meyer and Bristol Palin were engaged when she got pregnant, Meyer's extended family doesn't know much about Sarah Palin's daughter.
"I've met her but I don't really know her," Jean admitted. "But I helped raise Dakota and I do know him. He's a strong young man and a good one.
"He will be a father to his child and he'll be a good one he's just got to get this girl and the law to agree."
The Palins are livid that Meyer wants joint custody.
"For many months we have been trying to reach out to Dakota Myers [sic] and he has wanted nothing to do with either Bristol's pregnancy or the baby," Sarah Palin told Entertainment Tonight.
Palin believes Meyer is doing this to "save face."
Bristol and Meyer met while filming her mom's show, Amazing America in 2013. The decorated marine proposed to her last March at a Rascal Flatts concert.
Their wedding was to take place over Memorial Day weekend, but it was called off just days before.
