The transfer of an individual's interest in an individual investment account to his former spouse under a divorce decree or under a written instrument incident to a divorce shall not be considered a taxable transfer made by such individual notwithstanding any other provision of this subtitle, and such interest at the time of the transfer shall be treated as an individual investment account of such spouse and not of such individual. Thereafter such account shall be treated, for purposes of this subtitle, as maintained for the benefit of such spouse. If, during any taxable year of the individual for whose benefit the individual investment account is established, that individual engages in any transaction prohibited by section 4975 with respect to the account, the account shall cease to be an individual investment account as of the first day of that taxable year. If, during any taxable year, an individual for whose benefit an individual investment account is established uses the account or any portion thereof as security for a loan, the portion so used shall be treated as distributed to that individual. For purposes of this title, in the case of a custodial account treated as a trust by reason of the preceding sentence, the custodian of such account shall be treated as the trustee thereof.
