(1) In the cases governed by section 1314 (2) nos. 2 and 3, the petition may be filed only within one year, and in the cases governed by section 1314 (2) no. 4, it may be filed only within three years. The period for filing begins on the discovery of the mistake or the deceit or upon the duress having ended; however, the period for the legal representative of a spouse who is incapable of contracting does not begin before the date on which they become aware of the circumstances that cause the period to commence. Section 206 and section 210 (1) sentence 1 are to be applied accordingly to the running of the period.
(2) If the legal representative of a spouse without capacity to contract does not file the petition in good time, the spouse may file the petition themselves within six months after the incapacity to contract comes to an end.
(3) If the marriage has been dissolved already, the petition no longer may be filed.
