California Probate Form DE-310 Petition to Determine Succession to Real Property deals with estates of $150,000 or less in gross value. There are many sub rules to review in coming up with the $150,000. For example assets that are jointly titled or held in trust would generally NOT be considered in calculating the $150,000 in assets. The use of this petition does require a noticed hearing in Court. This as opposed to transferring personal property, worth less than $150,000, where no Court appearance is required.
