First, the DMV will probably transfer title of the car to your mother's children. You kids are then free to sell it. The 401k should have a named beneficiary, which passes outside of probate. If not, you will need to file probate to have her debts paid from the 401k funds. BTW, it is unlikely that your mother's estate if small enough for a "small estate affidavit." [The court and statutes count the market value of the house, without regard to the equity.] It would be well worth your time to discuss all this with a probate attorney, so you will have peace of mind.
