New Hampshire restricted insurer-required aftermarket parts on newer and leased vehicles

Effective January 1, 2017, New Hampshire added RSA 407-D:3-a and amended its aftermarket-parts disclosure law. Insurers may not require or specify aftermarket parts on vehicles placed in service within the immediately preceding two years with 30,000 or fewer miles, or on leased vehicles when the lease says the parts would reduce residual value. The chapter also requires written estimate disclosure and identification of aftermarket parts.

What to check

New Hampshire collision shops should flag newer low-mileage and qualifying leased vehicles when reviewing insurer estimates and verify that aftermarket-parts disclosures match RSA 407-D.
