Final answer:
To address a Planning Act violation found in a title search, a legal requisition letter is needed, outlining the breaches and requesting remedial action within a stipulated timeframe.
Step-by-step explanation:
When a title search reveals a violation of the Planning Act, the type of requisition letter required is typically a legal document that outlines the specific breaches and requests rectification within a certain period. This letter may be drafted by a lawyer or a legal professional and should be addressed to the property owner or the responsible party. It's important that the requisition letter be precise, professional, and includes all the necessary legal references to the violation and potential consequences if the issue is not resolved.
