What is Order of Precedence?

Complex contracts typically consist of multiple documents that together form the agreement: a master agreement, one or more schedules (scope, rates, SLAs), general terms and conditions, and any amendments or addenda. When those documents do not align perfectly (which occurs regularly in practice) the question arises as to which document prevails.

A precedence clause resolves this by establishing an explicit hierarchy. A typical hierarchy might be: (1) the master agreement, (2) schedules in order of date, (3) general terms and conditions. Where a conflict exists between a schedule and the general terms, the schedule prevails.

The most common sources of conflict are: a later-negotiated schedule that qualifies a provision in the master agreement, multiple versions of the same schedule without clear supersession of the earlier version, and general terms and conditions that are partially overridden by specific contractual provisions.

In back-to-back contracting, precedence is particularly important. When a main contractor mirrors its obligations to the client in its contract with a subcontractor, the precedence rules in both layers must be consistent. A divergent hierarchy in the chain can create liability gaps.

Without a precedence clause, a court determines priority based on interpretation of the parties' intent, an uncertain and expensive procedure that is easily avoided.

The order of precedence clause is one of the most overlooked provisions in complex contracts. Yet it is precisely this clause that determines, in a dispute, which version of reality prevails legally. Businesses that enter contracts with multiple schedules, amendments or recurring changes face serious uncertainty without an explicit hierarchy.

Establishing the hierarchy at the time of signing creates clear expectations and avoids costly interpretative disputes. It costs one sentence at signing and can save a fortune in litigation.
