§  4503.  Attorney.  (a)  1.  Confidential communication privileged. Unless the client waives the  privilege,  an  attorney  or  his  or  her employee,  or any person who obtains without the knowledge of the client evidence of a confidential communication made between  the  attorney  or his  or  her  employee  and  the  client  in  the course of professional employment,  shall  not  disclose,  or  be  allowed  to  disclose   such communication,  nor  shall  the  client  be  compelled  to disclose such communication,  in  any  action,  disciplinary  trial  or  hearing,   or administrative  action,  proceeding or hearing conducted by or on behalf of  any  state,  municipal  or  local  governmental  agency  or  by  the legislature  or  any  committee  or  body  thereof. Evidence of any such communication obtained  by  any  such  person,  and  evidence  resulting therefrom,  shall  not  be  disclosed  by  any state, municipal or local governmental agency or by the  legislature  or  any  committee  or  body thereof.  The relationship of an attorney and client shall exist between a professional service corporation organized under  article  fifteen  of the   business   corporation   law   to  practice  as  an  attorney  and counselor-at-law and the clients to whom it renders legal services.   2. Personal representatives. (A) For purposes of  the  attorney-client privilege,  if  the client is a personal representative and the attorney represents the personal representative in that capacity, in the  absence of  an agreement between the attorney and the personal representative to the contrary:  (i) No beneficiary of the estate is,  or  shall  be  treated  as,  the client  of  the  attorney  solely  by  reason  of  his  or her status as beneficiary;  (ii) The existence of a fiduciary relationship  between  the  personal representative  and  a  beneficiary  of  the  estate  does not by itself constitute or give rise to any waiver of the privilege for  confidential communications made in the course of professional employment between the attorney  or  his or her employee and the personal representative who is the client; and  (iii) The fiduciary's testimony that he  or  she  has  relied  on  the attorney's advice shall not by itself constitute such a waiver.  (B)  For  purposes  of this paragraph, "personal representative" shall mean   (i)   the   administrator,   administrator   c.t.a.,    ancillary administrator,  executor, preliminary executor, temporary administrator, lifetime trustee or trustee to whom letters have been issued within  the meaning  of  subdivision thirty-four of section one hundred three of the surrogate's  court  procedure  act,  and  (ii)  the   guardian   of   an incapacitated communicant if and to the extent that the order appointing such  guardian  under  subdivision  (c)  of  section 81.16 of the mental hygiene law or any subsequent order of any court expressly provides that the guardian is to be the personal representative of  the  incapacitated communicant  for  purposes of this section; "beneficiary" shall have the meaning set forth in subdivision eight of section one hundred  three  of the  surrogate's court procedure act and "estate" shall have the meaning set forth in subdivision nineteen of section one hundred  three  of  the surrogate's court procedure act.  (b)  Wills  and revocable trusts. In any action involving the probate, validity or construction of a will or,  after  the  grantor's  death,  a revocable  trust,  an  attorney  or  his  employee  shall be required to disclose information as to the preparation, execution or  revocation  of any  will,  revocable  trust, or other relevant instrument, but he shall not  be  allowed  to  disclose  any   communication   privileged   under subdivision (a) which would tend to disgrace the memory of the decedent.
