Subject
The study addresses whether a conclusive oath may be directed to prove a rent adjustment under a written lease, noting the prohibition on personal evidence in Article 29 of the Evidence Law, and considers the effect of inconsistent admission and denial on the admissibility of related defenses.
Summary
1) A conclusive oath is permissible to establish a rent modification for the first contractual year despite the ban on personal evidence in Article 29, being comparable in evidentiary weight to written proof. 2) The conclusive oath is a decisive evidentiary means that appeals to the opponent's conscience and, when taken, displaces other forms of evidence. 3) A tenant's prior admission of occupying the property precludes a later defense of non-enjoyment; an inconsistency between admission and denial undermines that defense.
