Yes, you will probably have to reopen the estate in order to distribute the funds.  The check is going to be made out to "the estate of" so a bank account is necessary too.  You need to give the court a valid reason to reopen.  Speak with the clerk of the court and although they can not give you legal advice but they can give you guidance.  You might want to have a conference with the court attorney as well.  Good luck.
