Can I add extra terms to a contract that has already exchanged?

Contracts often fail to address all relevant matters.  This might be because the parties never thought about a situation that has now arisen or because the parties took the view that an answer was so obvious they did not need to make provision in the contract to cover the position.

The contracting parties are usually free to amend contracts as many times as they wish or to tear up the first attempt and start over again.  As a practical matter, too many variations should be avoided as this may lead to the contract becoming unintelligible.

If the contract involves “land”, e.g. taking a new lease, then a distinction is drawn between deliberate (e.g. the parties decided to exchange one contract now for speed and to add extra items later when time permitted) and accidental omissions.  A deliberate omission can render the entire contract void and so it is safest to sign a brand new set of documents with the missing terms added and formally terminate the old documents.

If the omission was accidental and the other party will not agree an amendment you may be able to persuade the courts to correct an obvious drafting error in the contract (e.g. a transposition of names) or to clarify certain terms.  Where there has been some degree of fault by one party (e.g. the party knew of the error and encouraged the other party’s mistaken belief), the courts may be prepared to insert substantial new provisions.
