Quick answer: check whether the title reads OR or AND first. With OR, the survivor simply releases the title. With AND or sole ownership, use the DMV's own Form 827 if the estate qualifies.
A dedicated DMV form, not the general P-110
OR versus AND makes all the difference
Joint ownership with "OR" lets the surviving owner simply release the title, with no additional documents related to the deceased required. Sole ownership, or joint ownership with "AND," means the vehicle becomes part of the deceased owner's estate and must follow probate procedures unless the estate qualifies for Form 827.
A lost title has to be replaced first
If the title has been lost, a duplicate title must be obtained before any transfer can be processed.
A newer option in development: TOD for vehicles and boats
Alaska has been developing transfer-on-death titling for boats and vehicles through the DMV, letting an owner name a beneficiary in advance and adding that transfer to the state's list of accepted nonprobate transfers — worth checking current DMV guidance for availability.
A local probate attorney can review your estate — many offer a free consultation.
The Alaska DMV processes Form 827 the same way statewide, regardless of which borough or census area the decedent lived in — Alaska has no counties at all, unlike most other states.
