Certificate of Not The Same Person - Expiration date?

Hello! I was told before na wala expiration yun Certificate of NTSP (Not the Same Person) from Bureau of Immigration.
My last travel was 2012 pa and I have one Certificate of NTSP dated 2012. Wala kasi Valid till sa certificate. I remember way back 2006-2012 I traveled a lot. On my first travel on 2006, I was hold at the immigration but since it was my first time, they allow me to fly to HK but told me for my next travel I need the NTSP Certification. So on 2007 I got one, and have used it to travel between 2007 to 2012. then another one on 2012 (I misplaced the old one). I was told there was no expiration coz no expiry is indicated on both of my NTSP. Halos parehas lang laman ng NTSP ko.
2012 to now is like 12 years apart.
Can I still use my 2012 certificate for my travel next year?

If ever may expiration. I noticed na need meron court order clearance as one of the requirements. Yun ka same name ko nasa Davao, can I just bring my old NTSP? I don't think na makapag travel pa ako sa Davao just to get a court clearance. All I can present is Affidavit of NTSP, NBI and my old NTSP Certificate if need mag apply ulit.
