You can request your current landlord to provide you a copy, if she/he has this item in the file. Otherwise, you can contact your former landlord, or the escrow company that handled the sales transactions, to see if they can assist you with this. In the future, you should always make a copy of the documents you sign and keep them in your file.
I agree with Mr Marshall. I have a few additional thoughts. The question is a little vague as to when these events occurred. And, I am not sure what you mean by "estoppel." The concept is not usually used as it is in the question. Assuming it's some kind of agreement that prevented your former landlord for charging you for the storage space? It's a little tough to analyze without seeing the agreement.
Your use of the term "estoppel" makes me think that you've been using this space without charge for some time. If that's the case, be sure to present that fact in writing to the new manager and owner as well as evidence of the same (canceled checks for instance).
I don't think there is a bright line rule that states that you are entitled to receive a copy of the document at issue. If you still have a relationship with your former landlord, or can contact him/her, try doing so. As you have now learned the hard way- be sure to keep everything you have ever signed.
An attorney could likely assist you with this. It all comes down to a cost-benefit analysis as to whether retention of one would be worth the expense.
Best of luck to you!
