Questions people ask

What details does this template ask for?

The form asks for 18 details, starting with Project, Contract name or number, and date, Change order number, Client, Contractor. 7 more are optional.

Can I download this template as Word or PDF?

Yes. When you have filled in the form, save it as a Word document to keep editing, or as a PDF to send or print. It is free and needs no account.

Is what I type sent anywhere?

No. What you type stays in your browser while you fill in the document. It only goes to nerix if you choose to open the template in the chat.

What should I check before I use this template?

Follow the change procedure in your contract, including who may sign and any deadline for claiming extra cost or time. Get the signatures before the extra work starts where you can: a change agreed only by word of mouth is hard to prove. The totals are worked out from the figures you enter, so check them against your records.

Are these contract templates free?

Most are. You can fill in and download them for free as Word or PDF, with no account. A few long business agreements are premium: free to fill in, paid once to download, and marked with their price.

Is a template contract legally valid?

A signed agreement is usually valid when both sides understand and accept it, but rules differ by country and by type of contract. Treat a template as a careful starting point and check what applies where you are.

Do I need a lawyer to use a template?

For simple, low risk agreements many people do not. For large sums, property, employment disputes or anything unusual, ask a lawyer to review the draft first.

Can I change the terms?

Yes. Download the Word version and edit it, or ask nerix in the chat to make a clause stricter, shorter or in another language.
