Rule 21.3 Objection to documents founded on

Where a deed or writing is founded on by a party, any objection to it by any other party may be stated and maintained by exception without its being reduced.

Where an objection is stated under paragraph (1) and an action of reduction would otherwise have been competent, the sheriff may order the party stating the objection to find caution or give such other security as the sheriff thinks fit.

An objection may not be stated by exception if the sheriff considers that the objection would be more conveniently disposed of in a separate action of reduction.
