If you are on the registry, your name and address is posted for public viewing.

What Evidence Proves You Live In California?
This would include evidence of paying rent, securing employment or advising people that you have moved here.
Where Do You Register If Living On A College Campus?

Do You Need To Register If You Are Visiting A Friend?
Visiting and staying at a friend’s or relative’s home for a time does not qualify as residing there unless you show some intent.
How Does The Prosecution Prove You Knew You Had To Register?
To be prosecuted for failure to register as a sex offender, the prosecution must prove you had knowledge of your legal requirement to register7.
However, if there is a court record that indicates that you were ordered to register, even if only given orally in court, then you will likely be found to have had knowledge.
Is Being Notified In Court Enough?
You will be found to have had knowledge if the prosecutor gave you oral notice in open court that is verified by the court record.
When you were released from prison or jail, you were either given a written notice of your duty to register or an oral one by a representative of the Department of Corrections.
Also, when you were arraigned and given a copy of the complaint against you, the crimes of which you were charged will be ones for which a conviction requires registration.
How Does Ther Prosecution Prove I Willfully Failed to Register?
Willful failure is connected with the element of knowledge of your obligation to register since you cannot willfully or intentionally fail to register if you lacked the knowledge that you were ordered to do so8.
If circumstances caused a delay in your registering such as hospitalization, then you can use this to show lack of willful failure to register.
Penalties For Failing To Register as a Sex Offender
Penaltoes for Penal Code 290 PC – Failing to register as a sex offender depend on whether the underlying sex offense for which you were convicted was a misdemeanor and whether you have any prior convictions for failing to register.

If this is your first offense and you were convicted of a misdemeanor sex offense, then you will be charged with a California misdemeanor.
You face up to:
- 12-months in jail and/or
- A fine up to $1000.
Will the court give me a break if this is my first time failing to register?
It depends on your excuse for failing to register. If the court can be convinced that you did not register because of some emergency or that you did submit your registration information but that it was lost or have some other valid excuse, then the court might accept it and dismiss the charge against you.
What if I moved here from another state where I did not have to register?
You have a responsibility to find out if California will require you to register under its own laws. If you committed a sex crime that under California law would have required you to register, then you must register when you move here.
Penalty For Penal Code 290 If Your Underlying Offense Was A Felony
If the underlying offense was a felony, then failing to register as a sex offender is a felony offense. You face
- 16-months, 2 or 3 years in state prison,
- A fine up to $10,000
- formal probation.
It is also a felony if you had a prior conviction for failing to register regardless if it was a misdemeanor sex offense.
Further, if your obligation to register arose on multiple occasions, then you face a separate count for each time you failed to do so.
For example, if you failed to register when you moved from LA to San Francisco and again within 5 days of your birthday, then you face two charges of violating PC 290(c). You continue to violate the statute each time your duty to register arises so that you may face significant time in prison.
Can failure to register as a sex offender subject me to California’s 3-strikes law?
It can if you have two prior strikes and the sex crime for which you are required to register is a felony. Also, your two prior felonies must have been violent or serious felonies, which includes any sex crime committed with force, violence or the threat of it.
Other serious sex crimes are oral copulation, sodomy or sexual penetration with a person under the age of 14 and who is at least 10-years younger than you. A third strike means you face incarceration of 25 years to life.
Defenses For Failing To Register Under PC 290
There are a number of defenses available to a person who did not register as a sex offender when required to do so.
You Lacked Knowledge
Regarding lack of knowledge, your attorney might assert you lacked the mental capacity to understand or had some kind of cognitive disability in which you failed to understand what registering meant despite acknowledging your understanding in court or even signing your name to documents that included your obligation.
Lack of Registration was not Willfull
Another is arguing that you did not willfully neglect to register. Although you had knowledge, circumstances were such that you were unable to register. You may have been temporarily incapacitated, ill or hospitalized. If an emergency arose that caused you to miss the date, that may be a reasonable excuse as well.
If you can prove you mailed your registration, then the agency’s assertion that it did not receive the documents may be a valid excuse since mail can be lost or mislaid. Further, a clerk who entered your information may have done so erroneously.
