What changes to my estate plan can I not make during divorce?

You may not transfer, encumber, hypothecate, conceal, or in any way dispose of any property, real or personal, whether community, quasi-community, or separate, except in the usual course of business or for the necessities of life without consent of your spouse. 

You cannot create a “nonprobate transfer” or modify a “nonprobate transfer” in a manner that affects the disposition of property subject to the transfer without consent of your spouse.A “nonprobate transfer” includes, but is not limited to, revocable trusts, pension plans, employee benefit plans, IRAs, and life insurance. (Note: Pension plan beneficiaries are controlled by the Employee Retirement Income Security Act of 1974 (ERISA) (29 USC §§1001–1461), and the nonparticipant spouse is entitled to be the beneficiary under federal law.)
