Son, Beneficiary of Living Trust

(Lennox, CA USA)

My parents set up a living trust 15 years ago leaving me their residential property.(2 houses on lot) I have lived in one of the houses for 30+ years and still do. My mother passed away 12 years ago. Just recently, my father sold the property.

How does this effect my mom's wishes for me? Can my dad change what she stipulated in the trust? Can he take the $ from the sale ignoring what's said in the trust?
