When a tenant with arrears is vacated then tenanted into a new property, Chintaro will transfer the arrears from the old tenancy to the new tenancy. In the process, you can choose to treat the arrears as rent or other charges. 

If the arrears transfer is not required for a particular tenant, you can remove the arrears transfer transactions. 

In the screenshot Anna has arrears transferred from her old tenancy to her new tenancy as a transaction:

The old tenancy also shows the transfer of arrears with a transaction:

To remove the transferred arrears, double click each of these transactions and send then to the buffer.
