Fodd bynnag, mewn sawl achos sydd wedi dod i'm sylw yn ddiweddar, mae’n ymddangos nad yw'r gwarantau neu'r polisïau yswiriant perthnasol yn barod i dderbyn atebolrwydd neu na allant wneud hynny, ac o dan delerau rhai contractau lesddaliadau, mae'n ymddangos bod y lesddeiliad yn atebol yn ôl y gyfraith am gost y gwaith.
However, in several cases that have recently come to my attention, it appears that warranties or insurance policies are unwilling or unable to accept liability and under the terms of some leasehold contracts, legal liability for the cost of the work appears to rest with the leaseholder.
