This section applies if a mortgagee of land which consists of or includes a dwelling-house brings an action in any court for the enforcement of his security.
A connected person who is not already a party to the action is entitled to be made a party in the circumstances mentioned in subsection (3).
The circumstances are that—
the connected person is enabled by section 30(3) or (6) (or by section 30(3) or (6) as applied by section 35(13) or 36(13)), to meet the mortgagor's liabilities under the mortgage;
he has applied to the court before the action is finally disposed of in that court; and
the court sees no special reason against his being made a party to the action and is satisfied—
that he may be expected to make such payments or do such other things in or towards satisfaction of the mortgagor's liabilities or obligations as might affect the outcome of the proceedings; or
that the expectation of it should be considered under section 36 of the Administration of Justice Act 1970.
In this section "connected person" has the same meaning as in section 54.
