Landlord Fails to Repair After Request

Common questions
Frequently Asked
4
How is reasonable time determined when a contract or statute is silent?+
Courts and factfinders measure the period by the time a reasonable person would need to perform the required act under the particular circumstances, including the nature of the transaction, the parties' knowledge, and any commercial usages. The inquiry is fact-specific and avoids rigid formulas.
Supporting sources
Does a party's delay in demanding action affect whether a later response occurs within a reasonable time?+
A party's own delay in making a request or demand can shorten the period considered reasonable for the responding party, because the overall timeline must still allow the responding party a fair opportunity to act once notice is given.
Supporting sources
Can a reasonable time ever be measured in hours rather than days or weeks?+
Yes. When the need to preserve evidence or prevent immediate harm is urgent, a period as short as two hours may qualify as reasonable if the restraint is narrowly tailored and the authorities are acting diligently.
Supporting sources
What happens if a designated trustee neither accepts nor rejects within a reasonable time?+
The designated trustee is deemed to have rejected the trusteeship, freeing the settlor or beneficiaries to appoint a successor without further delay.
