Key features
Point to the original
Give its title, its date and a short description, so the addendum is tied to the right contract.
Choose the parts you are changing
Select one or more areas, such as payment or term, and describe the change.
Say what is added and removed
Write the wording being added and the wording being taken out, where you have it.
Set when it takes effect
Give the date the change applies from.
Both parties named
The parties are named and sign the addendum, with the original carrying on otherwise unchanged.
A lawyer reviews it before it is used
Your answers are prepared into a draft and reviewed by a qualified lawyer, rather than handed back to you as a finished form.
About this document
A contract addendum records a change to an existing agreement. It identifies the original, says what is being changed, and confirms that everything else stays as it was.
It is useful when the parties want to adjust a term, such as a fee, a date or the scope, without rewriting the whole contract.
The builder does not read your original agreement. You describe it and the change in your own words. Whether the change is effective, and whether the original allows it to be made this way, are questions a lawyer reviews.
