A certificate of inheritance or a certificate of executorship is an official record that authorises us to settle the estate with the person or persons designated in the certificate. It also states the rights of this person or these persons. We need this information to be sure that we are settling the estate with and for the right person. ABN AMRO is not the only party that may ask you for this certificate; other bodies may do so too.
You can get this certificate from a notary.
