Illinois Transfer of Firearms Question

As I understand it, now. If the recipient has a valid FOID. At the FOID website you can get a confirmation that their FOID is valid and print it out. The same for the present owner. Put that documentation with a letter describing the transfer. Done for each firearm. Must be kept for ten years.
Key word is now! FOID rules are about to change soon.

you must keep a record of what you transferred and when, and to whom. The ISP website will give you a transfer number after you input their FOID number and birthdate, if they are eligible (valid foid). Whether or not the rules will change is up in the air but I doubt it will get easier. S
Go to the ISP website, select "transfers" and follow the directions.

Provided all transfers happen at the same time, checking FOID validity once should be fine....but doing for each wouldn't hurt. The seller must record all info on the buyer (everything on the FOID card) and descriptions and serial numbers of each weapon. These records must be retained for 10 years and can be viewed by the police at any time upon their request. If the 'seller' dies, the estate would assume this responsibility through its executor or an attorney for record keeping. The 3 day waiting period applies for private transfers, too!
