seller doesn't want to use a lawyer

[Karen F.]

I'm buying a small apartment building.  The owner is a realtor.  Owner says they don't want to use an attorney, that they will represent themselves.  Owner is giving some seller financing.  I'm uncomfortable with this, so is my attorney.  He says that seller must have representation.  Is it legal in CT for seller who is not an attorney to represent self for a closing, and for a seller's financing loan?
