Legal Question in Wills and Trusts in California

Please see my previous answer which states that one-sixth of the estate will go to each child and each grandchild.

if no surviving spouse, each would get one-sixth.

Did the Decedent leave a Will or a Trust? If not, my colleague's answers above are correct. Also, the 1/6th share to deceased siblings would then be shared equally among their children. If a deceased sibling had no children, that share would be divided equally among the other siblings.

Based on the number of questions you have posted in this forum, I would suggest you contact a local attorney for assistance. The small expense will far outweigh the risks you are taking in not knowing the probate rules and laws of intestacy.

Again, was the decedent married at the time of death?

You are clearly not a lawyer. And based on your previous postings you are acting on behalf of someone other than yourself. That is a crime. Heed the advice of the previous answer and contact a local probate attorney before you really screw up the probate and find yourself in trouble with the courts on top of it all.
