applying for a visit visa to the uk would require you to submit the deed of sale to them. you will need to submit all necessary documents and they will keep all these docuements for review and then inform you after a few days or even weeks if they need to interview you.. its not like the US embassy interview where you just present your documents then and there and you will be handed it back during the interview after theyve looked at it.. please try to read the other forums so you can get a better idea as to how the process really is..
if you are referring to the original copy of the deed of sale this is the one im referring to that enables whoever it is who possesess it, can sell your property.. i advise you really not to submit this if you can..
what you can do as ive said earlier, is go to the registry of deeds in quezon city, bring the original deed all three of them to be sure, they will ask you to photocopy it there , fill up a form, pay at the counter, and then they will keep the photocopy of the deed of sale to process it for authentication, after that they will ask you to go back after 3 days... to claim the certified true copy of your deed of sale..
