It is usually expected that all parties attend the closing so that any problems that may occur are appropriately addressed. Some sellers choose not to attend and typically pre-sign the closing documents, giving a power of attorney to the lawyer representing them. However, it is uncommon for buyers not to attend the closing since many lenders require a borrower to attend a closing. Exceptions can be made but only if a lender gives prior permission and the lender approves the form of the power of attorney required to close in absentia. If there is no lender, then it is usually acceptable.
