Bailment in Common law and comparative study in Iran

Bailment, as a special legal concept in common law, has many controversies over its place, boundary, rule and effects. it has some resemblance to “Yade amani” (Custodial possession) in Islamic law. Most of these similarities are in their items but there are lots of differences in effects. But unfortunately it translated in Persian-English Dictionaries mistakenly as deposit contract or other concepts. This mistake translation could drive to other big errors in legal concepts. So working on this issue needs concentration on concepts, rules, effects and objects.
In common law, bailment sphere is becoming to some extent that arouse criticism of some Common law jurists. Consequence of this extensiveness is ambiguity in coverage. But common law courts accepted it and consider it as a source of obligation besides contract and tort.
In Islamic law, “Yade amani” is not a source of obligation but is a description for possession of possessor which sometimes neglectfully becomes description for contract
