Caveat, warning and apperance

[Mrs Jones]

my mother died leaving me her 51% share in a private limited company. Before probate and while a caveat was in place the directors of of company (one of which is and executor) transferred the shares to themselves and the other executor. She also left me the right to buy her property but because there are separate deeds for the 1. House and 2. The land, the executors have said I will not get the option to buy the land. The caveat is still in place and I'm now expecting a warning. The estates solicitors are acting for both the estate and the company. These solicitors also wrote the original will. While I'm happy to enter an appearance I can't afford legal representation having spent 10k getting nowhere. So I'm worried that if I lose, my only asset (my house) maybe at risk. What are your thoughts folks?
