Idaho Code § 67-7437
Except as otherwise provided in this section, any prize won under this chapter is not assignable. If the prize winner dies before the prize is paid, the prize shall be paid to the estate of the prize winner. A prize is subject to garnishment and recovery for unpaid taxes, child or spousal support or public assistance benefits paid and recoverable by the state or any county, or by a person pursuant to a judgment and execution under an order of the court. A prize shall also be subject to immediate withholding and set-off to collect any support delinquency or state taxes owed upon notification from the department of health and welfare pursuant to section 56-203E, Idaho Code, or the state tax commission pursuant to section 63-3060, Idaho Code. The state lottery shall not pay a prize claim until the lottery ticket or share has passed the validation tests established by the state lottery.
No prize shall be paid arising from claimed tickets or shares that are stolen, counterfeit, altered, fraudulent, unissued, produced or issued in error, unreadable, not received or not recorded by the state lottery by applicable deadlines, lacking in captions that confirm and agree with the state lottery play symbols as appropriate to the game involved, or not in compliance with such additional specific rules and regulations and public or confidential validation and security tests of the state lottery appropriate to the particular lottery game involved. Confidential validation or security tests shall be subject to disclosure according to chapter 1, title 74, Idaho Code.
No particular prize in any lottery game may be paid more than once, and in the event of a binding determination that more than one (1) claimant is entitled to a particular prize, the sole remedy of such claimants is the award to each of them an equal share in the prize.
