In the past, some pensions were set up based on a person working full time and so many years (let's say 30) Then, the were allowed to retire and collect a set, pre-determined amount till death. Sometimes, spouses could continue to receive the pension of a deceased pensioner. There were COLA's built into these sometimes, similar to SS. However, for many years now, many "pension" plans have significantly changed. You would be well advised to get an up to date, detailed version of your plan and understand it fully. Do NOT rely on what someone told you. Sometimes, back room deals are cut with union leadership and employers that never reach the membership. These are entered into the new contracts with very little notice. I would not negotiate a divorce settlement until I fully understood my pension plan and exactly how it works.
