Gov. Code, § 911.3

(a) When a claim that is required by Section 911.2 to be presented not later than six months after accrual of the cause of action is presented after such time without the application provided in Section 911.4, the board or other person designated by it may, at any time within 45 days after the claim is presented, give written notice to the person presenting the claim that the claim was not filed timely and that it is being returned without further action. The notice shall be in substantially the following form:

“The claim you presented to the (insert title of board or officer) on (indicate date) is being returned because it was not presented within six months after the event or occurrence as required by law. See Sections 901 and 911.2 of the Government Code. Because the claim was not presented within the time allowed by law, no action was taken on the claim.

Your only recourse at this time is to apply without delay to (name of public entity) for leave to present a late claim. See Sections 911.4 to 912.2, inclusive, and Section 946.6 of the Government Code. Under some circumstances, leave to present a late claim will be granted. See Section 911.6 of the Government Code.

You may seek the advice of an attorney of your choice in connection with this matter. If you desire to consult an attorney, you should do so immediately.”

(b) Any defense as to the time limit for presenting a claim described in subdivision (a) is waived by failure to give the notice set forth in subdivision (a) within 45 days after the claim is presented, except that no notice need be given and no waiver shall result when the claim as presented fails to state either an address to which the person presenting the claim desires notices to be sent or an address of the claimant.
