Based on the provided legal document, the assessment of rent does not necessarily depend solely on the existence of a deed or agreement. In the case discussed, the court considered the terms of the registered lease deed, which specified the consolidated rent amount, including furniture and fittings. The court emphasized that the rent as per the lease deed was Rs. 4,000 per month, and this figure was binding, regardless of the tenant’s claim that the actual rent was lower.

Furthermore, the court highlighted that in such matters, the consolidated figure of rent stated in the lease deed is relevant and should be taken into account. The argument that rent was only Rs. 2,500 per month was rejected because the lease deed explicitly mentioned the higher consolidated rent, including furniture and fittings.

Therefore, in the absence of a deed or agreement, rent assessment may involve other evidence such as rent receipts, payment records, or customary practice in the locality. However, the court primarily relies on formal agreements or documented terms to determine the rent amount. If no such agreement exists, the court may need to consider other credible evidence to assess the rent.

In summary, while a deed or agreement provides clear evidence of rent, their absence does not make rent assessment impossible. The court can determine rent based on other credible evidence, but formal agreements generally carry significant weight in such determinations.
