The problem is that mother-in-law lives in Iowa while you and your wife (her daughter) live in Nebraska. Your strategy would be legal if all three of you lived in Nebraska.
seems you are correct i called Omaha police @ 402-444-5818 and asked, the officer i spoke to said that if the gun crosses a state line it needs to be ffl-ed .. mailed from fedx or UPS to a local ffl dealer and 4473 form filled out for pick up by the new owner. so it seems you need to call around and find a dealer that has a low fee to be the ffl for you.. i talked to jeff at four aces pawn shop
http://fouracespawnomaha.com/gun-transfer-info/346292 and he charges 15 for the first gun and 5 for each additional so you may find a shop close to you with similar fee and lower fee for additional guns closer to home. best of luck ..
mother in law needs this info
FFL business name:
FFL business address:
FFL# :
on the box being ups or fedx-ed to a local shop close to you four aces wants a copy of her DL and contact info so they can call the last owner
this info is per a e-mail from jeff to me copied and pasted here
The only information a non-FFL holder needs to ship a handgun to a FFL holder is:
FFL business name Four Aces Pawn
FFL address 6604 N. 30 St
Omaha,NE 68112
FFL# 5-47-055-02-7F-10124
We would ask that the original owner or the person accepting responsibility for the disposition of the firearms, includes a copy of their state issued
drivers license or ID and a phone number or email address .
If you chose to use us as your transfer location, we charge $15 for the first firearm and $5 for each additional firearm on the same 4473 form.
