How to Update Separation Agreement

Hello,

We reached our 366 days a month ago. We discussed updating our separation agreement before filing our complaint for the absolute divorce. My question is, do I simply type a “modification to separation agreement” page and add it on the back end of the separation agreement and also get it notarized.

I used the free resources here for our original agreement, but I noticed there’s no examples of a modification or how to create one to attach to the original agreement before filing a complaint.

Thank you.
