My mom married a man that had been in a marriage for 10 plus years and divorced. So him and my mother was married for 5 yrs and divorced can she draw some of his social security?

Hi,

If I'm understanding you correctly, then no. Your mother would need to have been married to her ex-husband for at least 10 years prior to their divorce in order to potentially qualify for divorced spousal benefits (https://www.ssa.gov/planners/retire/divspouse.html).
