My ex and I divorced in 1991. He retired in 2014 from the RR and began receiving RR Retirement benefits. I also started receiving a small portion (less than $500/month) in 2014 and now, I may have to retire within the next year. I see from other messages that you mention "Tier 1 & Tier 2" RR retirement benefits. How do I find out what those are so I can be fully prepared with what my financial situation will be when I do have to retire.
