Dear Liz: My wife (71) and I (68) have been diligent savers our entire lives. We have accumulated IRA assets of approximately $2 million along with a house and other assets. Our total estate is under $10 million. We have two adult children in their 20s who did not inherit the saving gene. My question is: Does a trust exist that would maintain the IRA’s tax-deferred status, make required minimum distributions to our kids and include appropriate spendthrift provisions? Also, would the distributions be based on our life expectancies or on theirs?

Answer: Yes, you can create a spendthrift trust and name it as the beneficiary of your IRAs. Your children could be named beneficiaries of the trust. Required minimum distributions for inherited IRAs would be based on the elder child’s life expectancy. Your children would not be able to “invade” or tap the principal.

A spendthrift trust would not only prevent your kids from blowing through any money left in the IRAs. It also would prevent creditors from getting the money in case of bankruptcy. In many states, inherited IRAs are vulnerable to creditor claims.

Here’s the thing, though: This is a question you should be asking your estate planning attorney. If you don’t have one, you need to get one. People with small, simple estates may be able to get away with do-it-yourself planning, but yours is neither small nor simple. Trying to save money by using software or forms just isn’t a good idea. Whatever money you save may be wasted when your estate plan goes awry in ways you didn’t foresee, because you’re not an estate planning expert.

Trusts that name IRAs as beneficiaries, for example, must have special language to accomplish what you want, said Jennifer Sawday, an estate planning attorney in Long Beach. Without the right language, the IRA custodian might liquidate the IRA instead. That would trigger the taxes and lump sum payouts you’re trying to avoid.
