No. Spendthrift trusts, IRA accounts, 401K plans, and ERISA qualified retirement plans are not property of a bankruptcy estate. If an asset is not property of the estate, the debtor does not have to claim it as exempt to protect it from the claims of creditors; it is by definition beyond the reach of bankruptcy creditors and the trustee. The bankruptcy filing and the automatic stay would have no impact on the division or settlement of these types of accounts in a divorce proceeding.
