Buying a phone off somebody

[samsunggggggg]

If you buy a phone off somebody that is brand new or used can they just blacklist it after you buy it from them?

Unless it a stolen item and the owner blacklist it.

Thanks for the answer! Is there a way that I could stop that from happening? I'm scared that after i purchase the phone he will just black list it right after.
