if i have a lawyer and they withdraws from case without notifying me i only found out from x to be is that legal

Before withdrawing a lawyer needs to discuss the reasons with his/her client and attempt remedy whatever reason he/she has for requesting a withdrawal.  If there is a hearing scheduled, the lawyer must file a motion to withdraw and request court permission.  The lawyer must send a copy of the motion to you.  If there is no scheduled hearing, then the lawyer may file Withdrawl of Appearance without a motion but must send a copy of the client.  I hope this answers your questions.  Best wishes.
