As long as the date of transfer or change in ownership of real property between parent and child occurred on or before February 15, 2021, the transfer will qualify for the exclusion under Proposition 58/193. The date of death is the date of the change in ownership. The claim must be filed with the County Assessor within three years of the date of transfer or before a transfer to a third party or within six months of the date of notice of supplemental or escape assessment. Therefore, the claim does not need to be filed by February 16, 2021.
