You are correct. It MAY make it invalid, but not necessarily.

I am not sure exactly what you mean by 'maturity date', or what type of document to which you refer. However, if you are speaking of documents which relate to offers to purchase (documents of sale/purchase, etc.) a missing date may cause confusion in the stated terms of the document and may therefore allow an opening for either one or both of the parties to invalidate the agreement.

This does not prevent both parties from reaching an agreement to correct the date deficiency, which is pretty simple to do by addendum to the particular document, signed by both parties.

Legal Documents are easy to find. Your best bet is to search around online for a template that is closest to what you need and then review it and make changes until you are satisfied with it. A program like Simple Remote lets you set it up as a template and then generate it automatically for a specific property pulling all of the information from where you would anyway be storing just to keep track of what is going on with your business. good luck,
