Yes.  If you are filing for informal or formal probate, you will have to give notice to the persons entitled to notice by law.  Notice is an important step in the probate process.  In general, notice requirements are as follows:

Notice Requirements for Informal Probate:

An informal probate proceeding requires two types of notice:

(1)  Written notice at least 7 days prior to filing an informal petition with the court;

and

(2)  Publication notice within 30 days after the allowance of an informal petition.

Persons entitled to written notice may waive their statutory right to notice by completing an assent and waiver of notice using form MPC 455.

Notice Requirements for Formal Probate

A formal probate proceeding requires both written notice and publication notice prior to the allowance of the formal petition.  After the filing of a formal petition with proper payment, the Registry of Probate will issue formal notice to the petitioner.  The formal notice is called a citation.

A copy of the citation must be served on all interested persons as stated in the Order of Notice.  A copy of the citation must also be published in the newspaper listed in the Order of Notice.  

Persons entitled to written notice may waive their statutory right to notice by completing an assent and waiver of notice using form MPC 455.
