Query over will

Hi - please can you advise if it is the solicitors duty to ensure the executors act appropriately and in a timely manner?
I am the youngest of 3 sisters whose mum died in March making all 3 of us both executors and beneficiary’s - part of mums will also covered my brother who had a learning disability - he sadly died in May
1 sister managed mums affairs and the other my brothers
I have asked them for documents/ information etc and have been ignored
i asked the solicitor about this and he said in time I should receive something
is it not his role to peruse this? He said he was not asked to manage my brothers affairs so didn’t
please can you advise? Thank you
