When a seller places their property onto the market they have a legal obligation to produce an EPC certificate and provide certain information to the prospective seller upon request, usually through the sellers solicitor. Property enquiries have now been generally standardised in the form of a SPIF, a sellers property information form.  This form contains standard information to enquire whether the seller has any knowledge of previous or future circumstances that may affect the purchasers enjoyment of the property. Knowledge of boundary changes, disputes and complaints, notices and proposals, guarantees, planning alterations, known developments etc are usually considered.
