Security for costs or expenses.

This term is used among the civilians, Nov. 112, c. 2, and generally on the continent of Europe. In nearly all the countries of Europe, a foreign plaintiff, whether resident there or not, is required to give caution pro expenses; that is, security for costs. In some states this requisition is modified, and, when such plaintiff has real estate, or a commercial or manufacturing establishent within the state, he is not required to give such caution.
