INSTRUCTIONS FOR INFORMAL PROBATE WITH OR WITHOUT A WILL  

These general instructions are for informational purposes only and do not constitute legal advice.  Please consult an 
attorney if you have specific questions.  Court staff cannot provide legal advice or assist you with legal decisions.   

GENERAL INFORMATION  

Informal probate is an administrative proceeding to probate a will and/or appoint a Personal representative.  An 
administrative proceeding means that you do not have to have a hearing in front of a Probate and Family Court judge.   
  
If the decedent died with a will (testate), an informal petition may be filed to probate the decedent’s will with or without 
a request for the appointment of a personal representative.  An informal petition may also be filed for the informal 
appointment of a personal representative after the formal or informal probate of a will.  If the petitioner is requesting 
the appointment of a personal representative and the decedent died with a will that has not been probated, the 
petitioner must also request that the will be probated at that time.  

f the decedent died without a will (intestate), an informal petition may be filed to appoint a personal representative.   

nformal probate is unavailable if: 

the original will is lost, destroyed or otherwise unavailable; 

there is no official death certificate; 

the location or identity of any heir or devisee is unknown; 

the person to be appointed Personal representative does not have priority for appointment by statute or by 
renunciation and/or nomination; 

  an heir or devisee is an incapacitated or protected person or a minor and is not represented by a conservator or 

is only represented by a guardian who is also the petitioner; 

 the personal representative to be appointed is an interested person solely due to his or her status as a creditor 
or as a public administrator; 

the estate of a since deceased heir or devise is not represented by a personal representative;  

supervised administration is necessary; 

  a judge must sign an order or final decree for any reason. 

Note:  A determination of heirs and an adjudication of testacy are made only in a formal probate proceeding. 

The total fee required to file an informal petition is $390.00. The fee is broken down as follows:  $375 for the filing of the 
informal petition including all required forms/documents and a $15.00 surcharge to assign a docket number.  The 
$390.00 filing fee includes the initial appointment bond, notice forms and the initial court issued Letters of Authority but 
does not include publication costs.
