My wife worked for a school system in Texas (TRS) and has retired. She paid very little into Social Security in her life - mostly as part time work and never reached 40 credits. She was previously married for 35 years. It appears she is not eligible for spousal benefits on her previous husband. Is she eligible for a portion of mine? We have been married for 3 1/2 years. I am 70 and have been receiving benefits since 62. She is now 65.
