law: Workmen's Compensation Act, 1923 
  10. Notice and claim 
  (1) No claim for compensation shall be entertained by a
  
  Commissioner unless notice of the accident has been given in the manner
  
  hereinafter provided as soon as practicable after the happening thereof and
  
  unless the claim is preferred before him within two years of the occurrence of
  
  the accident or in case of death within two years from the date of death :
  Provided  that where the accident is the contracting of
  
  a disease in respect of which the provisions of sub-section (2) of section 3
  
  are applicable the accident shall be deemed to have occurred on the first of
  
  the days during which the workman was continuously absent from work in
  
  consequence of the disablement caused by the disease :
  Provided  further that in case of partial disablement
  
  due to the contracting of any such disease and which does not force the workman
  
  to absent himself from work the period of two years shall be counted from the
  
  day the workman gives notice of the disablement to his employer :
  Provided  further that if a workman who having been
  
  employed in an employment for a continuous period specified under sub-section
  
  (2) of section 3 in respect of that employment ceases to be so employed and
  
  develops symptoms of an occupational disease peculiar to that employment within
  
  two years of the cessation of employment the accident shall be deemed to have
  
  occurred on the day on which the symptoms were first detected :
  Provided  further that the want of or any defect or
  
  irregularity in a notice shall not be a bar to the entertainment of a claim -
  (a) if the claim is preferred in respect of the death of a
  
  workman resulting from an accident which occurred on the premises of the
  
  employer or at any place where the workman at the time of the accident was
  
  working under the control of the employer or of any person employed by him and
  
  the workman died on such premises or at such place or on any premises belonging
  
  to the employer or died without having left the vicinity of the premises or place
  
  where the accident occurred or
  (b) if the employer or any one of several employers or any
  
  person responsible to the employer for the management of any branch of the
  
  trade or business in which the injured workman was employed had knowledge of
  
  the accident from any other source at or about the time when it occurred :
  Provided  further that the Commissioner may entertain
  
  and decide any claim to compensation in any case notwithstanding that the
  
  notice has not been given or the claim has not been preferred in due time as
  
  provided in this sub-section if he is satisfied that the failure so to give the
  
  notice or prefer the claim as the case may be was due to sufficient cause.
  (2) Every such notice shall give the name and address of the
  
  person injured and shall state in ordinary language the cause of the injury and
  
  the date on which the accident happened and shall be served on the employer or
  
  upon any one of several employers or upon any person responsible to the
  
  employer for the management of any branch of the tread or business in which the
  
  injured workman was employed.
  (3) The State Government may require that any prescribed class
  
  of employers shall maintain at these premises at which workmen are employed a
  
  notice book in the prescribed form which shall be readily accessible at all
  
  reasonable times to any injuries workman employed on the premises and to any
  
  person acting bona fide on his behalf.
  (4) A notice under this section may be served by delivering it
  
  at or sending it by registered post addressed to the residence or any office or
  
  place of business of the person on whom it is to be served or where a notice
  
  book is maintained by entry in the notice-book.
