Quinn, ask your lawyer about the possibility of starting the probate process yourself if the Executor is holding off. Depending on your circumstances, it might be possible. Below is the section of the code dealing with that. In my case, I am a beneficiary of the Will so I am considered an "interested person". Sounds like you may have a similar situation. I am sure your lawyer could advise you on whether or not this is possible in your situation. I just found this out from my lawyer. But, disclaimer, I am not qualified to provide any legal advise. Just trying to let you know what I found out as a suggestion to discuss with your lawyer.
Sec. 256.051. Eligible Applicants for Probate of Will.
(a) An executor named in a will, an administrator designated as authorized under Section 254.006, an independent administrator designated by all of the distributees of the decedent under Section 401.002(b), or an interested person may file an application with the court for an order admitting a will to probate, whether the will is:
(1) in the applicant's possession or not;
(2) lost;
(3) destroyed; or
(4) outside of this state.
(b) An application for the probate of a will may be combined with an application for the appointment of an executor or administrator. A person interested in either the probate or the appointment may apply for both.
