Final answer:
In a QTIP marital deduction trust, the surviving spouse may have limited powers of appointment and the 5x5 power to retain election options for the executor.
Step-by-step explanation:
A QTIP (Qualified Terminable Interest Property) marital deduction trust allows the surviving spouse to have control over certain powers of appointment. The surviving spouse may be given limited powers of appointment, which allows them to distribute the trust's assets among a predetermined class of beneficiaries but with certain restrictions. They can also have the 5x5 power, which allows them to distribute up to 5% of the trust's assets among anyone they choose without any restrictions.
