On a sale, the purchaser shall not be entitled to require that the conveyance to him be executed in his presence, or in that of his solicitor, as such; but shall be entitled to have, at his own cost, the execution of the conveyance attested by some person appointed by him, who may, if he thinks fit, be his solicitor.

This section applies to sales made after the thirty-first day of December, eighteen hundred and eighty-one.
