More stipulated means something that is required to be done or agreed upon to a greater extent. Antonyms for more stipulated could be less specified, relaxed, flexible, or unbounded. Less specified means that something is not required to be defined to a greater extent than is necessary. If something is described as relaxed, it means that there is a greater degree of freedom in how it is done. Flexible means that there is more give and take in how something is executed. Unbounded means that there are no restrictions or limits in how something is done. These antonyms can help to describe a situation where a less rigid approach is needed.
