Legal Question in Wills and Trusts in California

You would not be entitled to anything unless you are a legatee under your mother in law's will, or listed as abeneficiary of her life insurance policy.

You may be asking the wrong attorneys. Your post says California but your postal says 39564, which is in Mississippi. You should get it straightened out and resubmit the question to attorneys in that state or those willing to seek local counsel in your state.

Unlikely. Unless you were specifically named as a beneficiary (under a will, trust or insurance policy), there is no right to inherit merely because you were married to the daughter, who is now deceased. Your children, if any, may be residual beneficiaries, but it would again depend on the wording.
