Well, the reason I asked is that, if you own the land, he's not allowed to build a sidewalk there. It's your land, and he would be trespassing if he tried to enter. The deed would specifically have to allow him to build the sidewalk.
Either way, though, a person cannot just dump land on someone else without that person's consent. You have the option of letting him know, in writing, that you do not want the property, that you refuse to accept it, and that you never agreed to the transfer. You may also want to consider calling to see if he will tell you his purpose in doing this, which could help you determine the next step.
If the deed has been recorded, it may be necessary to have a local attorney help get the deed reversed, or get a court order that he must pay the maintenance
fees. You could also try to write a paper stating that you refuse to accept the transfer, you did not give any consideration for the property, you do not want the property, there was never any agreement between you, and are not the legal owner of the property, then file that with the county. But you may still wind up in court.
