In-State Tuition Question

I’m considering several options in the UC system and have a question about in-state tuition.

I was born & raised in CA where I lived as a permanent resident, minus college dorms, until I was 24. However, I have been living out-of-state for nearly a year now and will have to renew my driver’s license soon, register to vote, etc. Do I forfeit the right to in-state tuition under these circumstances? It is unlikely I move back to CA in the near future unless it is to attend school, so I wanted to be aware if I needed to reestablish residency to get those in-state benefits.

Thanks!
