I'm a freelance web developer and I entered into a contract with a client in August 2018. The contract was set to end and product delivered by October 5 2018. However, due to the client changes in ideas and work in progress, we went way past that end date and now I am only going to deliver the final work in 2 days.
Given that there is a clause in the original agreement which states that in case of changes in ideas and the work takes more time at my sole discretion, then the client will allow more time to deliver. All of that is good.
However, I want to change the end date of the Original contract to November 2 2018 but I am not sure if that's possible, given it's already past October 5.
Can I actually amend the original contract now and say the end date changed to November 2nd 2018 and then amend some sections of the contract as well, to remove some sections and also to add some sections?
