Bueno pues ya tengo respuesta desde PZZ:
Dear Sir/Madam,
Our law states that the document that proves the ownership is the bill of sale or invoice. However we also accept the written statement form the owner that he is the owner from (pick the date). Underneath the clause about the submitting false testimony and the owner’s signature.
Es decir, que si no tenemos como es mi caso, copia del viejo contrato de compraventa, podemos hacer una declaración jurada de titularidad, así que genial
