For the unilateral termination of an agricultural land lease agreement due to non-payment of the agreed rent, the following core documents are usually required:

• the lease agreement
• identity documents of the parties
• title deeds / ownership documents
• where one of the parties is represented by an attorney-in-fact or is a legal entity, the relevant documents evidencing representation must also be provided.

In this case, it is necessary to prepare and send a Notice of Unilateral Termination of an Agricultural Land Lease Agreement due to Non-Payment of the Agreed Rent.

The notice must be served in a manner that proves it has reached the addressee, namely by postal mail, by courier with return receipt, or by notarial notice. In this way, you have evidence that the notice has been duly served and has reached the recipient.

Since the termination is due to non-performance, documents evidencing the non-payment of the lease installments are also usually required, together with any other relevant supporting evidence, if available. Depending on the specific case, it may also be necessary to prepare documents for notarization, registration, or filing before the relevant authorities.

The exact set of documents depends on the contents of the agreement, the grounds for termination, and the legal status of the parties.
