Retirement accounts are not normally covered by a will. Instead when you open an account like an IRA or 401(k), you need to designate a beneficiary. This ensures that any assets in your retirement account go to the person you wish upon your death.
With the company 401(k), however, your account will automatically pass to your spouse, unless a special waiver form is signed.
