What type of lawyer do I need when I feel the administrator of my son's affairs has not been fair?

2 weeks from returning from burial of son lawyer calls to tell me to have ex husband in charge of sons affairs due to my out of state availability, it was a wrongful death suit, I contacted lawyer in past two years asking about sons belongings and was told not to worry ex husband can't get rid of anything without my knowledge, plus that they started correspondence with me in my current married name (kept ex husband last name) and then switched to maiden name, check sent to me in maiden name I haven't used in over 30+ years and ex husband took out his expenses for funeral from award. We split funeral costs and I am still paying it on my credit card. I received none of the items from my sons room I requested which have very little monetary value only sentimental. Need to know how I can get someone to fairly look at this matter.
