Property tax issue

[Demetrius Crisco]

i just acquired an investment property at auction. I check before I bought it and it says that the property taxes are up to date. The last owner died like almost two years ago. I do not know who has been paying the taxes, it might have been the mortgage company. My question is.... How can I make sure someone does not acquire my property from paying the taxes? I just bought the property, my fear is that someone has been paying the taxes and now are gonna swoop in and the property becomes theirs. What should I do about this?
