No it is not required by law. In new construction they will generally give you a stove, microwave, and dishwasher as standard features but not a refrigerator. Of course in resale it is up to the seller. As long as you are not taking items that are considered real property ( a cooktop attached to the countertop or builtin units) when the unit was shown. Most appliances if they are not attached to the home or builtin with the intent of making them permanent then they are considered personal property and do not convey unless stated in the contract.
