I have an intestate succession inheritance. I am using Disclaimer, to prevent it from going to a person who has no right to it, even though I lose my share. But I don’t know if it’s ”Timely “. Ca Probate code §279 states that in order to be effective a disclaimer “shall be filed within a reasonable …. And it is “conclusively presumed to have been filed in reasonable time if filed in nine months after death of creator of interest or within nine months after interest is indefeasibly vested, whichever is later. QUESTION#1: Is an interest, indefeasibly vested on one person, if another claims all or part of the interest is her own? QUESTION#2: If it is not deemed indefeasibly vested’ technically a person can’t disclaim because it is not adjudged theirs , RIGHT?
