Nobel Peace Prize-winner President Juan Manuel Santos is championing the accord, against fierce opposition led by ex-president Alvaro Uribe.
Here are five bones of contention in the accord to end the 52-year conflict, revised after an earlier deal was narrowly rejected in a referendum last month.
The accord would offer special non-custodial sentences for FARC members convicted of crimes.
Opponents want tougher punishments for the worst atrocities.
The accord seeks to tackle the cocaine trafficking that has funded the FARC and fueled the conflict.
FARC members could be spared conviction on common drug charges if they can show they did not profit from it personally. Opponents say that grants impunity to drug traffickers.
Under the deal, the FARC pledge to declare all their assets and use them to compensate victims. Opponents say that does not give sufficient guarantees.
Uribe says it does not take into account the "pain" of thousands of people who were kidnapped and children who were recruited to fight.
The accord aims to transform the FARC into a political party.
Opponents complain it does not ban convicted FARC members from running for office before they have completed their sentences.
Santos plans to enforce the deal by having it voted on in congress, where he and his allies hold a majority.
Uribe demands the revised accord be put to another popular vote.
