Best endeavours definition

What does Best endeavours mean?

The terms 'best endeavours', 'reasonable endeavours' and the variations 'all reasonable endeavours', 'commercially reasonable endeavours' or 'reasonably commercial endeavours' and 'utmost endeavours' are frequently used in drafting commercial agreements and may be the result of considerable negotiation and often represent a compromise.

These terms represent a range of obligations at different ends of the spectrum. The most onerous obligation which can be imposed is a strict or absolute obligation. Next is the obligation of best endeavours followed by all reasonable endeavours. At the other end of the spectrum is the obligation to use reasonable endeavours. The precise obligations imposed by each of these terms is far from certain and have frequently been the subject of judicial interpretation with varying results.
