Under Idaho Code § 49-434, trailer owners have the convenience of registering utility trailers for 1 year, 5 years, or up to 10 years at the local County Assessor Motor Vehicle office, saving on annual renewal trips.

Q: Does an Idaho trailer bill of sale need to be notarized?

While standard sales of trailers with an unladen weight of 2,000 lbs or less do not statutorily require notarization if both parties sign, having Form SBF-ID-TRL notarized is strongly recommended by County Assessors to verify transaction authenticity, prevent ownership disputes, and avoid registration rejections.
