A document can be presented for registration beyond the period of 4 months of its execution

Under the Registration Act, a document can generally be presented for registration within four months of its execution. However, there are exceptions to this rule:

(B) Owing to urgent necessity: If there is an urgent necessity, a document can be presented for registration beyond the four-month period.

(C) Owing to unavoidable accident: If there is an unavoidable accident, such as circumstances preventing timely presentation, the document can also be presented for registration beyond the four-month period.

So, the document can be presented for registration beyond the period of four months if (B) and (C) conditions are present. It is not an automatic right (Option A) but is allowed under specific circumstances as exceptions to the general rule. Therefore, the correct answer is Only if (B) and (C) are present.
