Mods pls move na lang po if i'm in the wrong thread.

Need help po mga sir and peeps.

I bought a pre-owned car last Feb and now due for registration this month. Also planning to transfer the vehicle to my ownership . I did not notice until only yesterday that in the (Open) Deed of Sale where the
"IN WITNESS WHEREOF...." and "WITNESS MY HAND AND SEAL...." portions, the year typed was 2010 instead of 2011., NOTARY PUBLIC until Dec 2010 but Series of 2011

As I recall the seller furnished his own computerized format of the Deed of Sale to the lawyer's secretary in Manila City Hall where it was notarized though it's an open DOS.

AFAIK alterations/corrections will void this document, how will I go with the TMG and LTO process of ownership transfer?

I can no longer reach the previous owner/seller for his signature to execute a replacement deed of sale.

My questions are:
1. Will a Notary Public notarize a DOS without the presence of the Seller supposing I make a new copy and scan the seller's signature.

2. As the last two digits of my plate number is 1 & 5, will there be a penalty if I get to register until next week or week after.

Any enlightenment and suggestions will be greatly appreciated. Thanks in advance.
