Section 95 in Indian Evidence Act 1872
Title: Evidence as to document unmeaning in reference to existing facts

A sells to B, by deed, "my house in Calcutta".
A had no house in Calcutta, but it appears that he had a house at Howrah, of which B had been in possession since the execution of the deed.
These facts may be proved to show that the deed related to the house at Howrah.
Title: Evidence as to application of language which can apply to one only of several persons

Title: Evidence as to application of language to one of two sets of facts to neither of which the whole correctly applies
When the language used applies partly to one set of existing facts, and partly to another set of existing facts, but the whole of it does not apply correctly to either, evidence may be given to show to which of the two it was meant to apply.
A agrees to sell to B "my land at X in the occupation of Y". A has land at X, but not in the occupation of Y, and he has land in the occupation of Y but it is not at X. Evidence may be given of facts showing which he meant to sell.
