An ex wife can file 498A subject to the limitation period under S. 468 of the Cr.P.C. The offence under 498A is punishable with an imprisonment of up to 3 years. Section 468 of the Cr.P.C lays down a limitation period of 3 years for taking cognizance of an offence which is punishable with an imprisonment of a term not exceeding 3 years. Apart from this, the offence under 498A IPC is a continuing offence under S.472 Cr.P.C and, therefore, on every single occasion during the marriage the wife was treated with cruelty in relation to the demand of dowry, a fresh limitation period of 3 years would begin in her favour. Therefore, in terms of section 468 of Cr.P.C read with S. 472 Cr.P.C, an offence under 498A IPC can be taken cognizance of within 3 years from the date of last commission, irrespective of when the marriage was dissolved. To put in a nutshell, the dissolution of marriage would not hinder the wife from registering the FIR under 498A if the same fulfills the requirement of Sections 468 & 472 Cr.P.C.
