Collateral together and separately
A tenant and a landlord can agree on the order of priorities in using the collateral and can agree that there is no hierarchy of collateral.
In such a case the landlord can activate the number of collaterals at a time, as he sees fit.
For example, the parties agreed that the tenant would present a bank check as well as a guarantor for collateral to fulfill his obligations.
In the event that the tenant breaches the agreement, the landlord will strive to activate the securities.
The tenant of course will demand that the landlord first realize the bank check and only then turn to the securities.
And here, the landlord will have to decide whether by law he can turn to the guarantor at the same time as the realization of the bank check or not.
