If a person dies in the State of Texas without a will, there several options for the person who decides to handle the estate. Choosing the correct option depends upon the assets involved and if the heirs are in agreement on certain matters.
If no formal administration of the estate is necessary, there are two options: 1. Small Estate Affidavit (estates of $50,000 or less); or 2. Proceeding to Determine Heirship. These are both pretty simple process that can be done relatively cheaply with the help of an attorney.
If a formal administration is necessary, then there are still two choices: 1. Independent Administration (if all heirs agree on the appointment of an IA); or 2. Dependent Administration (when all the heirs do not agree on the appointment of the administrator; more expensive route).
If either of these latter two options is chosen, then along with the administration filing/proceeding, the administrator will also need to file an Application to Determine the Heirs (and the appointment of an ad litem attorney to assist the Court in determining the heirs of the estate).
To determine which step is necessary, you should consult an estate planning attorney.
