- What starts the clock
- The date of death ("מיום הפטירה") for the 12-month recommended submission window; the retroactive cap is counted back from the date the late application is submitted.
- How long
- 12 months from the date of death to submit; 12 months maximum retroactive payment if submitted late
- What is lost
- The source states that if the application is submitted late, the pension can be received for a retroactive period of at most 12 months. Entitlement for months earlier than that is not paid.
A survivors' pension (קצבת שאירים) application is recommended within 12 months of the date of death; a late application is paid retroactively for no more than 12 months.
What the source does not say
The source uses "מומלץ" (it is recommended), not a word of obligation, so the 12 months from death is presented as advice rather than a bar on filing; the page does not say whether filing later than 12 months affects anything beyond the retroactive cap. It does not state a longer retroactive window equivalent to the 48-month one on the old age page, and says nothing specific about survivors living outside Israel.
