The short answer
A condition is an event that must happen before a duty to perform arises, such as approval, inspection, or a prior payment. Disputes often turn on whether the condition occurred and who was responsible for it.
Where it fits in your case
When a party refuses to pay or perform because something has not yet happened.
What to expect
Prevention. A party that blocks or fails to cooperate in meeting a condition generally cannot rely on it.
Satisfaction clauses are usually judged by a reasonable-person standard for commercial matters and by good-faith judgment for matters of taste.
Simultaneous performance. When payment and delivery are due together, each side usually must be ready to perform.
What we need from you
The contract, approval or inspection records, and evidence of each side’s cooperation.
Common misconceptions
“They never approved, so we owe nothing.” Not if approval was withheld unreasonably or prevented.
“Satisfaction means whatever they want.” Often it means reasonable satisfaction.
