This answer was rated:

I signed a contract with someone to build something for me to meet the deadline. He however, was not able to make the deadline and ask me for additional sum of money to complete the project. Am i obliged to pay him the additional money?

Please explain to me in legal principles. I would like to do some research about this matter.
Thank you for your question here on Just answer. It is my pleasure to try and assist you with this today.

Did you agree that time was of the essence?
Customer: replied 4 years ago.

Yes it was. The timing was very important, because it can result in huge damages that may deprive me of my substantial benefit. I need the thing to complete a major project, which without it my company will suffer huge losses.

Why does he want more money to complete the job?

Have you paid?

How much money is involved?

Customer: replied 4 years ago.

He need it to complete the job on time.

There is actually case law on this and the answer is quite

An agreement to pay more money can be sufficient consideration if
you derive practical benefit. There must also be no economic duress.

The leading case is Williams v Roffey and Google will give you plenty of reading
however the circumstances are a bit different in that the contractor was
offered more money to get the job completed on time and the extra money that
was offered, was never paid. That is why he sued so it is a bit different than
yours in that in the case I quote they offered money whereas in your case, it
is being demanded.

It is also worth googling Stilk v Myrick which is probably closer
to your scenario.

In your particular case I think you are entitled to rely on the
price that is quoted. In addition, he is demanding money to finish the job
which puts you under pressure.

From a practical point of view, I would agree to pay him what he
is demanding but then don't pay it and let him sue you or, if he will not
finish the work without payment, pay him, wait until the job is finished and
then sue him for the money back on the basis that paid the pressure/duress

PS. I use voice type, voice recognition typing because I only
type with two fingers and it would take me ages. Sometimes, a computer does not
hear me correctly and you will get an incoherent word. I do try to but
sometimes they slip through. I apologise therefore if anything doesn't make sense.
It is me losing it, not you. Just ask if anything is not clear please.
