A solidary obligation, or an obligation in solido, is a type of obligation in the civil law jurisprudence that allows either obligors to be bound together, each liable for the whole performance, or obligees to be bound together, all owed just a single performance and each entitled to the entirety of it. (Wikipedia)

A joint and several obligation in common law corresponds to a civil law solidary obligation, i., one of several debtors bound in such wise that each is liable for the entire amount, and not merely for his proportionate share. (StuDocu)
