Is an attorney required in New York State?

[Joe P.]

I buy and sell vacant land in Pennsylvania.  Many of the properties I purchase are less than $2k.  For this reason it often does not make sense for me to hire an attorney/title company and purchase title insurance.  Many people aren't even aware that you can do this but with these smaller properties I simply have the seller notarize the deed and I send it to the county to be recorded.  I am looking at expanding to upstate New York and I have read that an attorney may be required to buy and sell land there.  Does anyone have any knowledge on this?  If attorney is required do both buyer and seller need one?
