Principle

Last verified: 1/01/2026

Risk follows responsibility

Risk follows responsibility

Legal scope

This principle is not regulated by statute and exists as an observed market rule arising from contract structure and allocation of legal responsibility.

Applicable acts / sections

— General contract law.

— Construction / Builders’ Lien legislation.

— Prompt Payment and Adjudication frameworks.

Observed principle

The party that assumes responsibility for outcomes, defects, delays, or third-party claims bears the corresponding legal and financial risk.

What it regulates

— Allocation of liability and exposure.

— Contract structure and internal pricing logic.

— Scope and necessity of insurance, bonds, and guarantees.

What it does not regulate

— Actual price levels or margins.

— Productivity, methods, or sequencing of work.

— Quality standards absent defined acceptance criteria.

Impact by role (legal position)

Worker          Limited responsibility, therefore limited risk and limited pricing power.

Company Greater responsibility results in higher risk and contractual exposure.
Client Risk may be transferred contractually, with cost increases reflecting that transfer.
Failure when ignored

Misalignment between assumed responsibility and contract pricing results in disputes, underpricing, non-performance, or uninsured losses.

Resolution mechanism

Applicable acts / sections

— Legal basis for completion and acceptance disputes.

What it does not regulate

Applicable acts / sections

— General contract law.

— Allocation of responsibility and risk.

What it does not regulate

— Fairness or market reasonableness of contractual terms.

Applicable acts / sections

— General contract law.

— Construction / Builders’ Lien legislation.
