Is there a way I can change my boys last name without their fathers permission and how ?
Well you can always add your last name ike me my name is miguel angel cervantes sosa my dads last name is cervantes and my moms is sosa
yes the mom has to approve n you would have to legally adopt them in other to do so. I just did that with my two boys from my wife.
Only if you are the legal guardian with full custody.
