N15 Form Question

I'm hesitant to go too into detail (for obvious reasons given the context of an N15 form being used), but ultimately I just need to clarify a detail of the N15 form to ensure it won't be an issue for me from a legal standpoint. I know I fit the required criteria of an N15, and I am a signed co-tenant. However, I never physically moved into the building (due to concerns relating to partner behaviour) prior to ending the relationship. That being the case the N15 uses phrases like "I will move out of the rental unit on or before this date." Given that I never moved in to begin with but am still a legally signed co-tenant, can I still effectively use this form without issue?

I have calls out to lawyers with no response to set up a call so far unfortunately. But any thoughts/guidance would be very appreciated as getting some distance and cutting ties with the co-signer for safety purposes is my top priority.
Thanks in advance.
