Live in CA. Father-in-law signed a pretty standard will 15 years ago. Divided his estate evenly, naming my husband as executor. Since then, we became joint tennant owners of his home, the deed listing us as 90% and him 10%. We verbally agreed with him that his estate would consist of the value of his 10% to be paid in cash to the three other siblings within two years of his death, while the house would become fully ours. This has been discussed with the other siblings, but is not in writing. Dad is dying, and may not last until June. Will the house automatically pass to us, as joint tennants? As he has little or no cash assets, will there be any need for probate? Can the siblings force an "execution" of the exisiting will to require dividing the 10% four ways, and payment before the agreed on two years?
