A quick claim deed was signed by duress on a house six years ago. Is it too late to dispute this?
There is no statute of limitations for a quitclaim deed. You are claiming that you are trying to set aside a quitclaim deed based on duress - which would normally be some form of tort under CO law - a threat, force, etc. - which would be 2 years. I am not really sure how you can quitclaim a deed in front of a notary under duress. Was a gun put to your head? Did they threaten to kill your family? Duress is a really serious accusation to make and there are certain requirements that must be met.

Mr. Leroi is correct. You would need some very strong facts to make a valid dispute.
