Establish a clear record of the firearm’s serial number and description
Document the exact date you took legal ownership
Protect yourself if the firearm was previously involved in an incident
Demonstrate responsible, law-abiding firearm ownership
For buyers, a signed GunTransfer bill of sale is proof that you own the firearm as of a specific date — critical if it is ever lost, stolen, or traced. GunTransfer makes this documentation simple for every private purchase in California.
