I would try the website that I listed below. I would also try calling the East Bay Community Law Center. You usually have to meet certain income qualifications to get help there, but I believe they also have a self-help center called CLASS where you can get assistance if you make too much money. I would also try the Alameda County Bar Association number at 510-302-2222. If you don't meet their income qualifications for free legal help, they may be able to refer you to someone who might be able to give you advice for a fee.

It seems Yves was able to clarify that rather than being at odds, the aunt and grandmother were intending to split the estate, so likely just a matter of getting a lawyer to work out the details as the case moves through probate, but I’m curious: It seems folks feel that if there was an effort by both spouse and mother of a deceased person to exclusively inherit the estate when there was no will, it would be the mother who would be considered next of kin. But when someone is on life support and doctors are asking for guidance on whether to pull the plug, it is the spouse who is considered next of kin. Why is it that you think in this case the mother would be considered next of kin?
