Breach of Tomlin order and subsequent specific performance order

[alanls]

The court issued a Tomlin order for a plot of land to be transferred
to me. The defendant did not adhere to the order therefore a hearing was
held for specific performance. The defendant agreed to transfer the plot
of land to me by a specific date. The TP1 and TR1 were sent to his
solicitors however they are incorrect and would not enable land registry
to transfer the land to me. Therefore the defendant is in breach of
specific performance, what options are available to me to deal with
this breach. I would like to add that the defendant is in prison for
fraud on another matter.
