In the U.S. it depends on the state. In some states, someone under 21 can own a handgun, but in some, they cannot. However, people under 21 can possess handguns for other legal reasons (like home self defense or target shooting) in almost every state...maybe every state.
Each state has it's own laws concerning handgun purchases (each country too). The best way to find out what your specific state requires is to look it up in the books, or on the internet, or the old fashioned way, ask a local cop. I think most states at 18 years old you can buy a handgun by yourself. Actually, asking a local cop is not a good way to find out about handgun laws. Checking with a reputable local gun store is usually the easiest way, but that's beside the point. Regardless, there is no such thing as a cosigner for a handgun. Most states (but not all) allow people under 21 to own or possess a handgun, and handguns can be given as a gift as long as the receiver qualifies to own the gun under their state laws. If your state law allows ownership of a handgun under the age of 21, you can purchase a handgun from an individual, or have a parent purchase the handgun from a licensed dealer for you as a gift (to be legal under federal law, it has to be a legitimate gift).
By using his parent/guardian's address, but his name on the envelope.
It depends on where you are. In the U.S. 11 year old children cannot own a handgun, but it is legal under federal and most states' laws to possess the handgun for legal purposes such as hunting and target shooting.
No, and that's federal law.
Can a parent legally kick-out their 17 year old in Michigan ?
Yes, a twelve year old can move in with the other parent.
You need to get a judge to expunge your records.
Yes they can.
a 27 year old woman.
Then the parent of the 21 year old must want their kid to go to prison for some reason.
Depends on the laws where you are- we get questions from SEVERAL nations, and laws vary. In the US, it will vary by state. The issue is not so much "can a minor own a handgun" as it is "Can a minor POSSESS a handgun?" Surprisingly, the answer MAY be yes- with the permission of the Minor's parents, on their own property, or in some instances, when the minor has the written permission of the parents. In some places, a 15 yr old may be working on a ranch, and be permitted to carry a handgun. While I would like to be able to give you a definitive yes/no answer, there are too many variables to do so. Sorry-
Certainly, if they have the parent's permission.
