In contrast with criminal cases, in civil cases one party sues another for an injury or harm that they feel the other party has committed against them. At issue is not whether the defendant is “guilty” or “innocent,” but whether or not he or she is liable, and if so, to what degree.
They both have very similar meanings, even if you look up synonyms for guilty, you can find liable.
I hope this helps, if not, comment and i will tell you in more detail.
Thx ;)
