My wife passed away before I turned 60. I remarried one day after I turned 60 so I would be eligible to file for survivor benefits. My former wife paid into Social Security for 30 years. My new wife is a retired teacher and receives a teacher's pension and will never receive Social Security since her union opted out of Social Security. My understanding is that her teacher's pension will not impact the amount I receive in survivor benefits nor in retirement benefits when I turn 70 and file for my social security benefit. Is that correct?
Yes, that's correct. The fact that your current wife receives a pension based on work that was exempt from Social Security taxes has no bearing on your Social Security benefits, whether you draw on your own record or on a former spouse's record.
