In re Douglas, 200 Cal.App.4th 236, 132 Cal.Rptr.3d 582, 588 (4th Dist. Oct. 27, 2011) (Though the trial court erred [in failing to advise the defendant of the sex offender registration requirement before plea], Defendant was almost instantly aware of the error when he signed the registration advisal form and received verbal notification on December 19, 1997. Despite this notice, Defendant chose to take no action for over a decade, and has thus forfeited his right to contest the error. While we recognize there may be advisements and rights so fundamental that the application of forfeiture doctrine is inappropriate, here we find the application reasonable and warranted. Defendant's deliberate inactivity for over a decade forfeited his right to challenge the Bunnell error.).
