If, at the time a person becomes the owner of a lot, another person is liable to pay a contribution in respect of the lot, the owner is jointly and severally liable with the other person for the payment of the contribution and any interest on the contribution.
A mortgagee or covenant chargee in possession of a lot is jointly and severally liable with the owner of the lot—
for any regular periodic contributions to the administrative fund or capital works fund together with any interest on those contributions, and
for any other contribution together with interest on that contribution taken to recover unpaid contributions, if the mortgagee or covenant chargee has been given written notice of the levy of the contribution, and
for any costs payable as a debtor in respect of enforcement action to recover unpaid contributions.
Subsection (2) does not affect the liability of an owner of a lot for any contribution levied under this section.
