How do I find out who the estate attorney is?

Generally, if you are an heir/devisee of an estate, the person who opens the estate (by petitioning the Court to open the estate and appoint them as personal representative) is required to give you notice of the proceedings. Whether they are required to do that before or after they petition the Court to open probate depends on whether or not they open probate formally or informally. 

If you receive notice of the proceedings as described above, the filings you receive should have the filing attorney's contact information in the case caption at the top of the filing(s), as well as on the signature block of any pleadings. 

If no person has filed to open an estate and be appointed as personal representative, then the questions become who has priority to serve as personal representative of the estate. If the Decedent has a will, and the will specifies a person(s) to serve as personal representative, that personal generally has priority. If there is no will, or if there is no one nominated in the will, the priority is determined by the statute. You can try reaching out to the person nominated in the will, or the family of the Decedent to attempt to ascertain if there are plans to open an estate and have a personal representative appointed, and if so, who is going to petition the Court to be personal representative, if they are represented/will be represented by an attorney, and who that attorney is. 

Importantly, you do not have to have priority to be appointed as personal representative. When it may be appropriate to petition without priority depends on the specific circumstances of each case.  

Further, if you are not an heir/devisee of an estate, you will likely not receive any notice, but didn't, you should contact an attorney to advise you of your rights. 

Last, keep in mind that no attorney technically represents the estate. The personal representative may have an attorney, but that attorney represents only the personal representative as a client (the estate is not their client). This is important to understand, because the attorney's duties are to their clients. The personal representative is the fiduciary for the estate, not their attorney.
